Description

Technical Field

[0001] The present invention relates generally to the field of detergents and cleaning compositions. In particular, the present invention relates to enzymatic detergents and cleaning compositions comprising specific hydroxyl compounds and having improved enzyme stability.

[0002] More specifically, the present invention relates to detergents and cleaning compositions comprising enzymes and an effective amount of 1,2-heptanediol and / or 2,3-heptanediol or a specific type of enzyme stabilizer such as an alkanediol with a carbon chain of 5 to 14 carbon atoms, caprylic acid glyceride, 4-hydroxyacetophenone, ethylhexylglycerol, tropolone or a mixture of said enzyme stabilizers and a surfactant, and the use of said detergents and cleaning compositions for preparing detergents and cleaning products for household, institutional and industrial applications. In addition, the present invention relates to the use of specific enzyme stabilizing substances as defined herein for stabilizing enzymes in detergents and cleaning compositions. Finally, the present invention relates to a method for stabilizing enzymes in detergents and cleaning compositions by adding an effective amount of a specific enzyme stabilizer such as an alkanediol with a carbon chain of 5 to 14 carbon atoms, caprylic acid glyceride, 4-hydroxyacetophenone, ethylhexylglycerol, tropolone or a mixture of said enzyme stabilizers to said detergents and cleaning compositions. Background Art

[0003] Detergents and cleaning compositions (especially for clothing and textile cleaning, dishwashing, etc.) consist mainly of surfactants or mixtures of surfactants, whose main task is to remove water-insoluble substances, such as dirt and grease, from surfaces of fabrics, clothes, dishes, utensils, etc., as well as from hard surfaces of metals, plastics, glass, ceramics, etc. In addition to surfactants, modern detergent and cleaning formulations consist of builders, chelating agents, co-builders, other polymer additives for specific washing or cleaning effects (such as soil removal and anti-redeposition, dye transfer inhibition and rheology modification), and enzyme stabilizers. In addition to the ingredients mentioned, one or more enzymes are added to the detergents and cleaning compositions as further active substances with a cleaning action.

[0004] Since the beginning of the 20th century, enzymes have been used in detergents and cleaning compositions. Enzymes can be used to improve the performance of detergents or cleaning agents. As is well known, enzymes are an effective chemical that is used together with detergents and other cleaning agents to decompose dirt. Enzymes decompose dirt, making them more soluble, and enable surfactants to remove them from the surface to provide enhanced substrate cleaning. Specifically, enzymes can provide desirable activity for removing stains such as protein-based, carbohydrate-based or triglyceride-based stains from substrates. Therefore, enzymes have been used in various cleaning applications to digest or degrade dirt, such as grease, oil (such as vegetable oil or animal fat), protein, carbohydrate, etc. For example, enzymes can be used as components for fabric care, cleaning textiles, warewashing, in-situ cleaning, cleaning drains, cleaning floors, cleaning carpets, cleaning medical or dental instruments, cleaning meat cutting tools, cleaning hard surfaces, for personal care, etc.

[0005] However, the use of enzymes in such detergents and cleaning compositions has proven difficult due to stability issues.

[0006] Proteins and / or enzymes may be damaged during storage, for example by inactivation, denaturation or disintegration (eg, by physical impact, oxidation or proteolytic cleavage).

[0007] The stability problems encountered are exacerbated over time and under storage or transport conditions at temperatures above standard ambient temperature (25°C), in particular above 35°C.

[0008] Most of the enzymes used are susceptible to the ingredients contained in the detergents and cleaning compositions, resulting in a loss of enzyme performance. Enzymes tend to be affected by surfactants and bleaches in the formulation. In addition, proteases also hydrolyze themselves (autoproteolysis) and all other proteins, especially enzymes. This occurs especially during cleaning, i.e. in aqueous washing liquids, when relatively favorable reaction conditions exist. This also occurs during storage of the composition, so that extended storage times also result in a certain loss of protease activity and the activity of other enzymes. This is particularly problematic in gel-like or liquid and aqueous formulations, since they demonstrate that the reaction medium and the hydrolysis agent are together with water.

[0009] In the past, many approaches have been taken to improve the stability of enzymes for storage. For example, borate-based stabilization systems have been used to try to address the stability of enzyme formulations.

[0010] However, the use of such stabilizing systems has some disadvantages. First, compositions containing borates are under scrutiny and regulations have been proposed that would limit their incorporation, and might even exclude them altogether. Second, compositions based on borates do not provide the desired level of stability. Boric acid derivatives, in addition to their stabilizing effect, have a key disadvantage: many of these boronic acid derivatives, such as borates, form undesirable byproducts with other detergent and / or cleaning agent ingredients, rendering them no longer usable in the relevant agents for their desired purpose, or even remaining as impurities on the items to be cleaned.

[0011] Other attempts to stabilize enzymes in detergents and cleaning compositions include the use of ingredients that have undesirable effects, such as amine oxides and / or alkyl polyglucosides. These ingredients are problematic because they foam. In many cleaning situations, particularly including medical and dental instrument cleaning, detergents and cleaning compositions that minimize foaming are desired so that the surface being cleaned remains visible.

[0012] Loss of enzyme performance in detergent and cleaning compositions results in loss of cleaning performance.

[0013] The detergent and cleaning industry is constantly searching for ingredients that can address these negative aspects.

[0014] Therefore, there remains a continuing need for materials having the ability to improve enzyme stability in detergent and cleaning compositions.

[0015] It is therefore an object of the present invention to provide multi-purpose enzyme-containing detergent and cleaning compositions having excellent enzyme stability in detergent and cleaning compositions and thus having improved cleaning performance.

[0016] Furthermore, it was an object of the present invention to provide enzyme-containing detergents and cleaning compositions which provide better enzyme stability compared to detergents and cleaning compositions comprising conventional enzyme stabilizers.

[0017] Another object of the present invention is to provide substances which are able to stabilize enzymes or enzyme mixtures in detergent and cleaning compositions.

[0018] Finally, it is another object of the present invention to provide a method for stabilizing enzymes in detergent and cleaning compositions.

[0019] Finally, another object of the present invention is to provide an enzyme composition comprising an enzyme and an enzyme stabilizer.

[0020] Surprisingly, it has been found that adding an effective amount of a specific type of enzyme stabilizer (such as an alkanediol having a carbon chain of 5 to 14 carbon atoms, caprylic acid glyceride, 4-hydroxyacetophenone, ethylhexylglycerol, tropolone or a mixture of said enzyme stabilizers, as defined herein) to detergents and cleaning compositions comprising an enzyme or an enzyme mixture has a positive impact on enzymatic performance, as they significantly slow down the rate of enzyme inactivation by effectively stabilizing the enzyme or enzyme mixture. The enzymes in these detergents and cleaning compositions show excellent stability during storage, thus maintaining performance over time. More specifically, the enzymatic detergents and cleaning compositions exhibit stability after storage for at least 2 weeks and at temperatures above standard ambient temperature (25°C), in particular above 35°C.

[0021] Additionally, based on the improved enzyme stability, the enzyme can work longer and thus provide more cleaning benefits by effectively removing soil and / or stains.

[0022] Conversely, also due to the excellent stability of the enzymes, the amount of enzymes and other ingredients used to increase the effectiveness of the enzymes in these detergents and cleaning compositions (such as enzyme stabilizers) can be reduced to achieve similar cleaning results, ie, without sacrificing cleaning performance.

[0050] As contemplated herein, the term "detergent and cleaning composition" should be understood to mean all products suitable and commonly used for washing or cleaning. Detergent and cleaning composition are mainly composed of a surfactant or a mixture of surfactants. In addition to surfactants, detergents and cleaning compositions are usually composed of builders and chelating agents, co-builders and other polymer additives for specific effects (such as decontamination, anti-redeposition, dye transfer inhibition, rheology modification). Detergent and cleaning composition refers to a composition that can be used to remove undesirable compounds from textiles (such as fabrics, clothes), dishes, floors, hard surfaces (such as metals, plastics and ceramics) waiting to be cleaned. These deposits may be caused by dirt or stains, bacteria and other contaminants. Detergent is the cleaning composition most commonly used for textiles. Detergent and cleaning composition can be used for household cleaning, public institution cleaning and industrial cleaning. Detergent and cleaning composition also contain disinfectants that kill all vegetative cells (including recognized pathogenic microorganisms). Detergent and cleaning composition can be used by the detergent composition itself or by detergent products or by its use solution.

[0051] The detergent and cleaning compositions according to the first and second aspects of the present invention are preferably used for removing stains and / or soils from textiles, fabrics, laundry, dishes, utensils, medical and dental instruments, hard surfaces and the like.

[0052] Within the scope of the present invention, the terms "cleaning" and "washing" are used synonymously and refer to the reduction and / or removal of deposits, i.e. the removal of undesirable compounds from the items to be cleaned on tableware / dishes and other kitchen utensils (such as cutlery / silverware, pots, pans, bakeware, etc.).

[0053] These deposits may be caused by stains from tea, chocolate, coffee, grass, red wine, grass / mud, juice, blood, tomato puree, unused motor oil, salad dressing balsamic vinegar, cooked beef fat, French mustard, make-up etc. or dirt caused by grease, starchy dirt (such as rice, pasta), proteinaceous dirt (such as egg yolk, chocolate, mayonnaise), lipstick starchy dirt etc. and other dirt remaining on the surface. Deposits are therefore any form of undesirable residues of pollutants, dirt, food, grease etc.

[0054] In the context of the present invention, the term "substrate" includes fabrics, textiles, clothing, dishes, utensils, any hard surface, medical and dental instruments, etc., which may be stained and / or soiled and may be treated by a washing or cleaning process.

[0055] As used herein, the term "fabric cleaning" includes detergents and cleaning compositions or products designed to clean stained and / or soiled materials. Such compositions or products include, but are not limited to, laundry detergent compositions, fabric softening compositions, fabric enhancing compositions, fabric refreshing compositions, laundry pre-wash, laundry pre-treatment, laundry detergent additives, spray products, dry cleaning agents or compositions, laundry rinse additives, laundry additives, post-rinse fabric treatments, ironing aids, unit dose formulations, delayed delivery formulations, detergents contained on or in porous substrates or nonwoven sheets, substrates with fibers (preferably the fibers include an active agent), and other suitable forms apparent to those skilled in the art.

[0056] As used herein, the term "fabric care" refers to various fabric benefits including smoothness, shape retention, resiliency, color protection, pilling control, and the like.

[0057] As used herein, the term "dish" or "ware" refers to solid surfaces such as countertops, tiles, floors, walls, panels, windows, sanitary ware, kitchen and bathroom furniture, appliances, engines, circuit boards, and dishes. Hard surfaces can include, for example, health care surfaces, such as medical or dental instruments, medical or dental devices, electronic devices for monitoring patient health, and surfaces of floors, walls, or fixtures of structures where health care occurs, and food processing surfaces, such as surfaces of tools, machines, equipment, structures, etc. used as part of food processing, preparation, or storage activities. In the context of the present invention, the term "ware" refers to items such as eating and cooking utensils, dishes, and other hard surfaces (such as showers, sinks, toilets, bathtubs, countertops, windows, mirrors, and floors).

[0058] As used herein, the term "surface" refers to solid surfaces such as countertops, tiles, floors, walls, panels, windows, plumbing fixtures, kitchen and bathroom furniture, appliances, engines, circuit boards, and dishes. Hard surfaces can include, for example, health care surfaces such as medical or dental instruments, medical or dental devices, electronic devices used to monitor patient health, and surfaces of floors, walls, or fixtures of structures where health care occurs, as well as food processing surfaces such as surfaces of tools, machines, equipment, structures, etc. used as part of food processing, preparation, or storage activities.

[0059] As used herein, "enzyme stabilizers" (b) are substances that stabilize enzymes in detergent and cleaning compositions during storage for at least 2 weeks and at temperatures above standard ambient temperature (25° C.), in particular above 35° C. The agent is different from "additional enzyme stabilizers" (d) which are generally known in the art and which are used in addition to enzyme stabilizers to provide an additional enzyme stabilizing effect.

[0060] Surprisingly, it has been found that adding an enzyme stabilizer as described herein or a mixture of enzyme stabilizers to detergents and cleaning compositions stabilizes the enzymes in the detergents and cleaning compositions during storage. In this way, the enzymatic properties of such detergents and cleaning compositions and thus the cleaning performance can remain stable.

[0061] Based on this advantageous effect, the detergents and cleaning compositions according to the invention provide enzyme stability during storage for at least 2 weeks and at temperatures above standard ambient temperature (25° C.), in particular above 35° C., as well as improved cleaning performance.

[0062] Enzymes or enzyme preparations / components (a1, a2, a3, a) The enzymatic detergents and cleaning compositions according to the invention comprise as component (a1, a2, a3, a) at least one enzyme or an enzyme formulation comprising at least one enzyme which provides cleaning performance by removing stains and / or soils, and / or fabric care benefits.

[0063] As is well known, enzyme is an effective chemical substance, which is used together with detergent and other cleaning agents to decompose dirt. Enzyme decomposes dirt, makes them more soluble, and enables surfactant to remove them from the surface, to provide enhanced substrate cleaning. Specifically, enzyme can provide ideal activity, for removing stains such as protein-based, carbohydrate-based or triglyceride-based from substrate. In addition, enzyme also helps to improve washing results at lower temperatures. Therefore, enzyme has been used in various cleaning applications, to digest or degrade dirt, such as grease, oil (such as vegetable oil or animal fat), protein, carbohydrate etc. For example, enzyme can be used as a component addition of the composition for laundry, textiles, warewashing, in-situ cleaning, cleaning drains, floors, carpets, medical or dental instruments, meat cutting tools, hard surfaces, personal care etc.

[0064] Enzymes suitable for use in detergents and cleaning compositions can act by degrading or modifying one or more types of soil residues encountered on an apparatus or device, thereby removing the soil or making the soil more removable by a surfactant or other component of the cleaning composition. Both degradation and modification of soil residues can improve detergency by reducing the physicochemical forces that bind the soil to the apparatus or device being cleaned (e.g., the soil becomes more soluble in water). For example, one or more proteases can cleave complex macromolecular protein structures present in soil residues into simpler short-chain molecules that themselves are more easily desorbed from a surface, dissolved, or otherwise more easily removed by a cleaning solution containing the protease.

[0065] The detergent enzyme according to the present invention has cleaning, stain removal, stain removal or other beneficial effects as a component of detergents and cleaning compositions, which are used for instruments, devices or equipment (such as medical or dental instruments, devices or equipment); or for laundry, textiles, dishwashing, cleaning in place, drains, carpets, meat cutting tools, hard surfaces, personal care, etc.

[0066] Enzymes that can be used in detergents and cleaning compositions according to the present invention include enzymes that provide desirable activity for removing protein-based, carbohydrate-based, or lipid-based (fat-based or oil-based) stains and / or soils from substrates; for cleaning, stain removal, stain removal and disinfecting presoaks, such as presoaks for medical and dental instruments, devices and equipment; presoaks for flatware, cooking utensils and tableware; or presoaks for meat cutting equipment; for machine warewashing; for laundry and textile cleaning and stain removal; for carpet cleaning and stain removal; for cleaning in place (CIP) and stain removal in place; for cleaning and stain removal of food processing surfaces and equipment; for drain cleaning; presoaks for cleaning; etc.

The cellulase can be purified, or a component of a microbial extract, and is wild type or variant (chemical or recombinant). Preferred cellulases are commercially available under the following trade names: Celluclean ® and Carezyme ® , each available from Novozymes; and Revitalenz ® , available from DUPONT / IFF.

[0074] The selection of preferred enzymes depends on the conditions of final use, including physical product form, use pH, use temperature and soil type to be degraded or altered, and is influenced by factors such as pH activity and / or stability optimum, thermostability and stability to active detergents, builders, etc. Enzymes can be selected to provide optimal activity and stability for any given set of use conditions. In this regard, bacterial or fungal enzymes are preferred.

[0075] Proteases, amylases and lipases are the most commonly used enzymes in detergents and cleaning compositions. Proteases are particularly useful for cleaning protein-containing soils, such as egg, milk, meat residues, etc. Amylases are particularly useful for removing starchy soils, such as pasta and rice. Lipases are particularly useful for cleaning soils that include fats / greases.

[0076] As will be determined by those skilled in the art, enzymes are designed to work on specific types of soils. For example, according to one embodiment of the present invention, a dishwashing application may use a protease because the protease is effective at the high temperatures of a dishwashing machine and is effective in reducing proteinaceous soils. Proteases are particularly useful for cleaning proteinaceous soils such as blood, skin flakes, mucus, grass, food (e.g., eggs, milk, spinach, meat residues, ketchup), etc.

[0077] According to the present invention, enzyme compositions can vary based on the specific cleaning application and the type of soil that needs to be cleaned. For example, the temperature of a specific cleaning application will affect the enzyme selected for use in the enzyme composition according to the present invention. Warewashing applications, for example, clean substrates at temperatures exceeding about 60°C, or exceeding about 70°C, or between about 65°C and 80°C, and enzymes such as proteases are ideal due to their ability to retain enzymatic properties at such elevated temperatures. Laundry washing applications, for example, clean clothes at temperatures exceeding about 40°C, or exceeding about 50°C, or between about 65°C and 90°C, and enzymes such as proteases are ideal due to their ability to retain enzymatic properties at such elevated temperatures.

[0078] Preferably, the at least one enzyme in the detergent and cleaning composition is selected from the group consisting of proteases, amylases, lipases, gluconidases, cellulases, peroxidases or mixtures thereof.

[0079] In some variations, the enzyme in the detergent and cleaning compositions is a protease, amylase, lipase, cellulase, gluconidase, peroxidase, mannanase, or any mixture thereof.

[0080] Preferably, the enzymes in the detergent and cleaning compositions are a mixture of proteases, amylases, lipases, cellulases and / or pectate lyases.

[0081] Preferred detersive enzymes in detergent and cleaning compositions include hydrolases such as proteases, amylases, lipases or combinations thereof.

[0082] Preferably, the enzyme in the detergent and cleaning composition is a protease, amylase, lipase, cellulase, peroxidase, gluconidase or any mixture thereof.

[0083] In still more preferred variations, the enzymes in the detergent and cleaning compositions disclosed herein are proteases, amylases, lipases or any mixtures thereof.

[0084] Still more preferably, the enzyme in the detergent and cleaning compositions is a protease, an amylase or a mixture thereof.

[0085] Still more preferably, the enzyme in the detergent and cleaning compositions is a protease, a lipase or a mixture thereof.

[0086] More preferably, the enzymes in the detergent and cleaning compositions are selected from amylases, lipases or mixtures thereof.

[0087] In some other embodiments, the enzymes in the detergent and cleaning compositions are proteases.

[0088] In yet other variations, the enzyme in the detergent and cleaning compositions is an amylase.

[0089] In yet other variations, the enzyme in the detergent and cleaning compositions is a lipase.

[0090] In yet other variations, the enzyme in the detergent and cleaning compositions is a cellulase.

[0091] Preferred enzymes in detergents and cleaning compositions according to the present invention for cleaning medical or dental devices or instruments include proteases, amylases, cellulases, lipases or combinations thereof.

[0092] Preferred enzymes in detergents and cleaning compositions according to the present invention for food processing surfaces and equipment include proteases, lipases, amylases, gluconidases or combinations thereof.

[0094] Preferred enzymes in detergents and compositions for carpets include proteases, amylases or combinations thereof.

[0095] Preferred enzymes in the detergent and cleaning compositions according to the present invention for meat cutting tools include proteases, lipases or combinations thereof.

[0096] Preferred enzymes in detergent and cleaning compositions according to the present invention for hard surfaces include proteases, amylases, lipases or combinations thereof.

[0097] Preferred enzymes in the detergent and cleaning compositions according to the present invention for drains include proteases, amylases, lipases or combinations thereof.

[0098] For stain removers, the enzyme is preferably selected from the group consisting of proteases, amylases, lipases, mannanases, pectate lyases.

[0099] For fabric softeners, the enzyme is preferably a cellulase.

[0100] To increase the bleaching effect, an oxidoreductase is optionally added to the detergent and cleaning compositions according to the first and second aspects of the present invention.

[0101] The oxidoreductase is selected from the group consisting of oxidases, oxygenases, catalases, peroxidases (such as haloperoxidases, chloroperoxidases, bromoperoxidases, lignin peroxidases, glucose peroxidases or manganese peroxidases), dioxygenases or laccases (such as phenol oxidases and polyphenol oxidases) and any mixtures thereof.

[0102] Commercial enzymes are available in liquid or dry form (i.e., pucks, powders, etc.), sold as untreated aqueous solutions or in various purified, processed, and compounded forms established in the prior art, and contain from about 0.1% to about 80% by weight of active enzyme, typically in combination with stabilizers, buffers, cofactors, impurities, and inert vehicles. The actual active enzyme content depends on the manufacturing method and is not critical; provided that the detergent and cleaning composition has the desired enzymatic properties.

[0103] This comprises, for example, solid enzyme preparations obtained by granulation, extrusion or freeze drying, or, particularly in the case of liquid or gel-like medicaments, comprises a solution of enzyme, which is advantageously concentrated as far as possible, has a low water content and / or adds a stabilizer. Alternatively, for solid and liquid application forms, the enzyme can be encapsulated, for example, by spraying or extruding the enzyme solution with a preferred natural polymer, or in capsule form, for example, a capsule in which the enzyme is encapsulated, such as in a solidified gel, or in a capsule of a core-shell type, wherein the core containing the enzyme core is coated with a protective layer of watertight, air and / or chemicals. Other active substances (for example stabilizers, emulsifiers, pigments, bleaching agents or dyestuffs) can be applied in the form of superimposed layers. Such capsules are applied using methods known per se, for example, by vibration or rolling granulation or in a fluidized bed process. Advantageously, such particles are low in dust, for example, due to the application of polymer film formers, and are storage-stable due to the presence of coatings. In addition, two or more enzymes can be packaged together so that a single particle exhibits a variety of enzyme properties.

[0104] In a variant according to the invention, the enzyme is added to the detergent and cleaning composition as a single enzyme.

[0105] In some other variants, the enzyme added to the detergent and cleaning composition is preferably an enzyme mixture of two, three, four or even more different enzymes. Typically, for laundry detergents, the enzyme mixture contains two (preferably protease and amylase) to six enzymes. For dishwashing detergents, a typical enzyme mixture contains two enzymes (preferably protease and amylase).

[0106] Still more preferably, the enzyme is added to the detergent and cleaning composition as an enzyme formulation in the form of a mixture with an enzyme stabilizer, preferably in combination with one or more enzyme stabilizers (b1, b2, b3, b) as defined herein, and / or a mixture with one or more commonly used enzyme stabilizers, such as the enzyme stabilizers (d1, d2, d3, d) described below, optionally a buffer, etc.

[0107] Preferred combinations of enzymes and specific types of enzyme stabilizers (b), such as alkanediols having a carbon chain of 5 to 14 carbon atoms, glyceryl caprylate, 4-hydroxyacetophenone, ethylhexylglycerol, tropolone or mixtures of said enzyme stabilizers, are described in detail below.

[0108] Enzyme stabilizer / component (b1, b2, b3, b) The enzymatic detergent and cleaning compositions according to the invention further comprise at least one enzyme stabilizer as component (b1, b2, b3, b).

[0109] In a preferred variant, the enzymatic detergent and cleaning compositions according to the invention comprise a mixture of enzyme stabilizers.

[0110] Enzyme stabilizers within the meaning of the present invention are (b I ) at least one linear alkanediol having a carbon chain of 5 to 14 carbon atoms or a mixture comprising at least one first linear alkanediol having a carbon chain of 5 to 14 carbon atoms and one or more second linear alkanediols having a carbon chain of 5 to 14 carbon atoms different from the first linear alkanediol; (b) II ) caprylic acid glyceryl ester; (b III ) 4-Hydroxyacetophenone; (b IV ) ethylhexylglycerin; (b V )tropolone; and any mixture of said enzyme stabilizers.

[0111] The enzyme stabilizer is found to effectively stabilize the enzymes in detergents and cleaning compositions and thereby slow down the rate of enzyme deactivation during storage. In this way, the cleaning performance of the detergents and cleaning compositions is maintained over time.

[0112] Alkanediols (b1, b2, b3, b I ） Component (b) in the enzymatic detergent and cleaning composition according to the first aspect of the present invention is 1,2-heptanediol (b1) or 2,3-heptanediol (b2), or a mixture comprising the two heptanediols, namely 1,2-heptanediol plus 2,3-heptanediol (b3).

[0113] 1,2-Heptanediol belongs to the class of alkanediols and is a straight chain alkanediol having the following general formula:

[0114] It has a carbon chain containing 7 carbon atoms, and the two functional OH groups of the alkanediol are in the α, β positions and chemically bonded to the C1 and C2 carbon atoms in the alkanediol chain.

[0115] 2,3-Heptanediol belongs to the class of alkanediols and is a straight chain alkanediol having the following general formula:

[0116] It has a carbon chain containing 7 carbon atoms, and the two functional OH groups of the alkanediol are in the β, γ positions and are chemically bonded to the C2 and C3 carbon atoms in the alkanediol chain.

[0117] Alternatively, the enzyme stabilizing component (b) in the detergent and cleaning composition according to another aspect of the present invention is selected from the group consisting of: (b I ) at least one linear alkanediol having a carbon chain of 5 to 14 carbon atoms or a mixture comprising at least one first linear alkanediol having a carbon chain of 5 to 14 carbon atoms and one or more second linear alkanediols having a carbon chain of 5 to 14 carbon atoms different from the first linear alkanediol.

[0118] An alkanediol is any of a class of organic compounds belonging to the alcohol family, ethylene glycol; in the ethylene glycol molecule, two hydroxyl groups (-OH) are attached to different carbon atoms of the carbon chain.

[0119] Straight-chain 1,2-alkanediols have been used as multifunctional actives for more than 15 years. Short-chain 1,2-alkanediols are amphiphilic compounds and, like 1,2-pentanediol, 1,2-hexanediol and 1,2-heptanediol, are therefore soluble in water and oil. In contrast, 1,2-octanediol is a solid and tends to precipitate or recrystallize in oily solutions and in water at ≥ 0.5%. 1,2-decanediol, on the other hand, is a solid and is only soluble in oil. In addition to moisturizing, some 1,2-alkanediols are used as viscosity modifiers.

[0120] In a first alternative, the enzyme stabilizer (b) of the detergent and cleaning compositions according to another aspect of the invention is at least one linear alkanediol having a carbon chain of 5 to 14 carbon atoms.

Most preferably, the at least one linear alkanediol has a carbon chain of 7 to 9 carbon atoms. Most preferably, the at least one linear alkanediol has a carbon chain of 7 or 8 carbon atoms.

[0123] Furthermore, in a second alternative of this another aspect, the enzyme stabilizing component (b) may comprise a combination of a first linear alkanediol and a second linear alkanediol, preferably at least one having a carbon chain of 5 to 14 carbon atoms (preferably a carbon chain of 6 to 14 carbon atoms, more preferably a carbon chain of 7 to 14 carbon atoms, more preferably a carbon chain of 7 to 12 carbon atoms, still more preferably a carbon chain of 7 to 11 carbon atoms, and even more preferably a carbon chain of 7 to 10 carbon atoms, and most preferably a carbon chain of 7 to 9 carbon atoms, and most preferably 7 or 8 carbon atoms), and at least one second linear alkanediol having a carbon chain of 5 to 14 carbon atoms, preferably a carbon chain of 6 to 14 carbon atoms, more preferably a carbon chain of 7 to 14 carbon atoms, more preferably a carbon chain of 7 to 12 carbon atoms, still more preferably a carbon chain of 7 to 11 carbon atoms, and even more preferably a carbon chain of 7 to 10 carbon atoms, and most preferably a carbon chain of 7 to 9 carbon atoms, and most preferably a carbon chain of 7 or 8 carbon atoms. Therefore, the present invention also relates to a mixture comprising the first alkanediol and the second alkanediol as described herein.

[0143] This means that the enzyme stabilizer is an alkanediol mixture comprising at least one first linear alkanediol having a carbon chain of 5 to 14 carbon atoms and one or more (i.e. two, three, four or more) second linear alkanediols having a carbon chain of 5 to 14 carbon atoms. In this alternative, the first linear alkanediol can be any alkanediol described herein generally for linear alkanediols and in particular for the first alternative in another aspect.

[0145] The second linear alkanediol preferably consists of a chain of 5 to 14 carbon atoms linked to each other by a single covalent bond, wherein the two OH functions are linked to two different carbon atoms in the chain.

[0157] The phrase "different from each other" means that the first linear alkanediol and the second linear alkanediol in the mixture differ in their carbon chain lengths (ie, the number of carbon atoms) or in their configurational isomerism.

[0158] Likewise, the first straight-chain alkane diol and the second straight-chain alkane diol in the mixture may have the same number of carbon atoms. For example, the first straight-chain alkane diol and the second straight-chain alkane diol have carbon chains of 7 carbon atoms, but the first straight-chain alkane diol and the second straight-chain alkane diol differ in their configurational isomerism or in their stereoisomerism.

[0161] If both the first alkanediol and the second alkanediol have the same number of carbon atoms, this alkanediol combination is also referred to herein as a "homoalkanediol mixture" or a "homocombination." For example, the first linear alkanediol and the second linear alkanediol have carbon chains of 7 carbon atoms, but the first linear alkanediol and the second linear alkanediol differ in their configurational isomerism or in their stereoisomerism.

[0162] If the first alkanediol and the second alkanediol have different numbers of carbon atoms, this alkanediol combination is also referred to herein as a "heteroalkanediol mixture" or "heterocombination". For example, the first linear alkanediol has a carbon chain of 7 carbon atoms and the second linear alkanediol has a carbon chain of 8 carbon atoms. However, in addition to this, the first linear alkanediol and the second linear alkanediol may differ in their configurational isomerism or in their stereoisomerism.

[0163] In a preferred variant, the present invention relates to a detergent and cleaning composition, wherein the at least one linear alkanediol or the first linear alkanediol is chosen from the group consisting of pentanediol, hexanediol, heptanediol, octanediol, nonanediol, decanediol, undecanediol, dodecanediol, tridecanediol and tetradecanediol; and / or the second linear alkanediol is chosen from the group consisting of pentanediol, hexanediol, heptanediol, octanediol, nonanediol, decanediol, undecanediol, dodecanediol, tridecanediol and tetradecanediol.

[0164] Particularly preferred are enzyme stabilizer mixtures wherein the at least first linear alkanediol is selected from alkanediols having a lower number of carbon atoms of 5 to 8, and wherein the one or more second alkanediols are selected from alkanediols having a higher number of carbon atoms of 9 to 14.

[0165] Most preferred is an enzyme stabilizer mixture wherein the at least first linear alkanediol is selected from the group consisting of pentanediol, hexanediol, heptanediol, octanediol and any mixture thereof, and the one or more second alkanediols are selected from the group consisting of nonanediol, decanediol, undecanediol, dodecanediol, tridecanediol and any mixture thereof.

[0166] The term "alkanediol" in the context of the present invention also includes its configurational or positional isomers. Configurational isomers are compounds with the same molecular formula but with different linkages. Positional isomers (a specific form of configurational isomerism) are structural isomers that can be considered to differ only in the position of the functional groups on the parent structure, in this case especially the position of the two alcohol functional groups.

[0167] Depending on the number of carbon atoms in the carbon chain of the alkanediol, there are various positional isomers of the alkanediol: (x,x+1) configuration isomers; (x,x+2) configuration isomers; (x,x+3) configuration isomers; etc., as well as α,ω configuration isomers when the alcohol functional group is located at the end of the carbon chain, where x represents the number of carbon atoms in the alkanediol chain to which the OH group of the alkanediol is chemically bonded. For example: if x is 1, the two OH groups of the alkanediol are chemically bonded to the C1 and C2 carbon atoms in the alkanediol chain; if x is 2, the two OH groups of the alkanediol are chemically bonded to the C2 and C3 carbon atoms in the alkanediol chain, etc.

[0168] In the (x,x+1) configuration isomer, the two OH functional groups are ortho-attached to two different adjacent carbon atoms in the chain. In the (x,x+2) configuration isomer, the two OH functional groups are attached to two different carbon atoms in the chain, where the two carbon atoms are separated by one C atom. In the (x,x+3) configuration isomer, the two OH functional groups are attached to two different carbon atoms in the chain, where the two carbon atoms are separated by two C atoms. In the α,ω configuration isomer, the two functional groups are attached to the first C atom and to the terminal C atom.

[0238] According to a preferred variant, the at least one linear alkanediol or the at least one first linear alkanediol is chosen from the group consisting of 1,2-alkanediols having a higher number of carbon atoms (and more particularly more than 10 carbon atoms), namely 1,2-undecanediol, 1,2-dodecanediol, 1,2-tridecanediol or 1,2-tetradecanediol.

Therefore, 1,2-alkanediols with a higher number of carbon atoms (and more specifically more than 10 carbon atoms) are effectively used as enzyme stabilizers in detergents and cleaning compositions containing enzymes. Improved enzyme stability in detergents and cleaning compositions leads to better cleaning performance.

[0240] In a more preferred variant, the at least one linear alkanediol or the at least one first linear alkanediol is selected from the group consisting of 2,3-alkanediols having a number of carbon atoms of 6 to 14, i.e. 2,3-hexanediol, 2,3-heptanediol, 2,3-octanediol, 2,3-nonanediol, 2,3-decanediol, 2,3-undecanediol, 2,3-dodecanediol, 2,3-tridecanediol, 2,3-tetradecanediol and any mixture thereof, or from the following The group consisting of: 2,3-alkanediols having 7 to 14 carbon atoms, i.e., 2,3-heptanediol, 2,3-octanediol, 2,3-nonanediol, 2,3-decanediol, 2,3-undecanediol, 2,3-dodecanediol, 2,3-tridecanediol, 2,3-tetradecanediol and any mixture thereof, or selected from the group consisting of: 2,3-alkanediols having 7 to 12 carbon atoms, i.e., 2,3-heptanediol, 2,3-octanediol, 2,3-nonanediol, 2,3-decanediol, 2,3-undecanediol, 2,3-dodecanediol, 2,3-tridecanediol, 2,3-tetradecanediol and any mixture thereof. 2,3-decanediol, 2,3-undecanediol, 2,3-dodecanediol and any mixture thereof, or selected from the group consisting of: 2,3-alkanediol having 7 to 11 carbon atoms, i.e., 2,3-heptanediol, 2,3-octanediol, 2,3-nonanediol, 2,3-decanediol, 2,3-undecanediol and any mixture thereof, or selected from the group consisting of: 2,3-alkanediol having 7 to 10 carbon atoms, i.e., 2,3 -heptanediol, 2,3-octanediol, 2,3-nonanediol, 2,3-decanediol and any mixture thereof, or selected from the group consisting of: 2,3-alkanediols having 7 to 9 carbon atoms, i.e., 2,3-heptanediol, 2,3-octanediol, 2,3-nonanediol and any mixture thereof, or selected from the group consisting of: 2,3-alkanediols having 7 and 8 carbon atoms, i.e., 2,3-heptanediol, 2,3-octanediol and any mixture thereof.

[0245] Studies have found that these alkanediols show particularly significant enzyme stabilization properties. Therefore, 2,3-alkanediols with a lower number of carbon atoms are effectively used as enzyme stabilizers in detergents and cleaning compositions containing enzymes. Improved enzyme stability in detergents and cleaning compositions leads to better cleaning performance.

Thus, 1,2-alkanediols having a higher number of carbon atoms (and more specifically more than 10 carbon atoms) are effectively used as enzyme stabilizers in detergents and cleaning compositions containing enzymes. Improved enzyme stability in detergents and cleaning compositions results in better cleaning performance.

[0284] In a more preferred variant, the at least one second linear alkanediol is selected from the group consisting of 2,3-alkanediols having a number of carbon atoms of 6 to 14, i.e. 2,3-hexanediol, 2,3-heptanediol, 2,3-octanediol, 2,3-nonanediol, 2,3-decanediol, 2,3-undecanediol, 2,3-dodecanediol, 2,3-tridecanediol, 2,3-tetradecanediol and any mixtures thereof, or selected from the group consisting of 2,3-alkanediols having a number of carbon atoms of 7 to 14, i.e. 2,3-hexanediol, 2,3-heptanediol, 2,3-octanediol, 2,3-nonanediol, 2,3-decanediol, 2,3-undecanediol, 2,3-dodecanediol, 2,3-tridecanediol, 2,3-tetradecanediol and any mixtures thereof. 2,3-alkanediol having 14 carbon atoms, i.e., 2,3-heptanediol, 2,3-octanediol, 2,3-nonanediol, 2,3-decanediol, 2,3-undecanediol, 2,3-dodecanediol, 2,3-tridecanediol, 2,3-tetradecanediol, and any mixture thereof, or 2,3-alkanediol having 7 to 12 carbon atoms, i.e., 2,3-heptanediol, 2,3-octanediol, 2,3-nonanediol, 2,3 2,3-decanediol, 2,3-undecanediol, 2,3-dodecanediol and any mixture thereof, or selected from the group consisting of: 2,3-alkanediols having 7 to 11 carbon atoms, i.e., 2,3-heptanediol, 2,3-octanediol, 2,3-nonanediol, 2,3-decanediol, 2,3-undecanediol and any mixture thereof, or selected from the group consisting of: 2,3-alkanediols having 7 to 10 carbon atoms, i.e., 2,3-heptanediol alcohol, 2,3-octanediol, 2,3-nonanediol, 2,3-decanediol and any mixture thereof, or selected from the group consisting of 2,3-alkanediols having 7 to 9 carbon atoms, i.e., 2,3-heptanediol, 2,3-octanediol, 2,3-nonanediol and any mixture thereof, or selected from the group consisting of 2,3-alkanediols having 7 and 8 carbon atoms, i.e., 2,3-heptanediol, 2,3-octanediol and any mixture thereof.

[0285] The study found that the 2,3-alkanediols exhibit particularly significant enzyme stabilization properties. The alkanediols are therefore effectively used as enzyme stabilizers in detergents and cleaning compositions containing enzymes. The improved enzyme stability in the detergents and cleaning compositions leads to better cleaning performance after storage compared to detergents and cleaning compositions without the addition of such alkanediols.

[0286] In still more preferred variations, the second linear alkanediol is selected from the group consisting of 2,3-alkanediols having a lower carbon number of 5 to 8, i.e. 2,3-pentanediol, 2,3-hexanediol, 2,3-heptanediol, 2,3-octanediol and any mixtures thereof, or from the group consisting of 2,3-alkanediols having a carbon number of 6 to 8, i.e. 2,3-hexanediol, 2,3-heptanediol, 2,3-octanediol and any mixtures thereof, or from the group consisting of 2,3-alkanediols having a carbon number of 7 and 8, i.e. 1,2-heptanediol, 1,2-octanediol and any mixtures thereof.

[0287] In a still more preferred variation, the second linear alkanediol is 2,3-pentanediol or 2,3-hexanediol or 2,3-heptanediol or 2,3-octanediol, or any mixture thereof. In a still more preferred variation, the second linear alkanediol is 2,3-heptanediol or 2,3-octanediol, or any mixture thereof.

[0288] In a most preferred variation, the second linear alkanediol is 2,3-heptanediol.

[0289] Studies have found that these alkanediols show particularly significant enzyme stabilization properties. Therefore, 2,3-alkanediols with a lower number of carbon atoms are effectively used as enzyme stabilizers in detergents and cleaning compositions containing enzymes. Improved enzyme stability in detergents and cleaning compositions leads to better cleaning performance.

[0290] In a still more preferred variant, the second linear alkanediol is selected from the group consisting of 2,3-alkanediols having a higher carbon number of 9 to 14, i.e. 2,3-nonanediol, 2,3-decanediol, 2,3-undecanediol, 2,3-dodecanediol, 2,3-tridecanediol, 2,3-tetradecanediol and any mixtures thereof, or from the group consisting of 2,3-alkanediols having a carbon number of 9 to 13, i.e. 2,3-nonanediol, 2,3-decanediol, 2,3-undecanediol, 2,3-dodecanediol, 2,3-tridecanediol and any mixtures thereof, Or selected from the group consisting of: 2,3-alkanediols having 9 to 12 carbon atoms, i.e., 2,3-nonanediol, 2,3-decanediol, 2,3-undecanediol, 2,3-dodecanediol and any mixture thereof, or selected from the group consisting of: 2,3-alkanediols having 9 to 11 carbon atoms, i.e., 2,3-nonanediol, 2,3-decanediol, 2,3-undecanediol and any mixture thereof, or selected from the group consisting of: 2,3-alkanediols having 9 and 10 carbon atoms, i.e., 2,3-nonanediol, 2,3-decanediol and any mixture thereof.

[0291] In a still more preferred variation, the second linear alkanediol is 2,3-nonanediol or 2,3-decanediol or 2,3-undecanediol or 2,3-dodecanediol, or any mixture thereof.

[0292] According to a preferred variant, the second linear alkanediol is chosen from the group consisting of 2,3-alkanediols having a higher number of carbon atoms (and more particularly more than 10 carbon atoms), namely 2,3-undecanediol, 2,3-dodecanediol, 2,3-tridecanediol or 2,3-tetradecanediol.

[0293] These alkanediols were found to show better enzyme stabilization properties. Thus, 2,3-alkanediols having a higher number of carbon atoms (and more specifically more than 10 carbon atoms) are effectively used as enzyme stabilizers in detergents and cleaning compositions containing enzymes. Improved enzyme stability in detergents and cleaning compositions results in better cleaning performance.

[0296] In a particularly preferred variant, in the detergent and cleaning compositions according to the invention, the linear alkanediol is selected from the group consisting of 1,2-pentanediol, 1,2-hexanediol, 1,2-heptanediol, 1,2-octanediol, 1,2-nonanediol, 1,2-decanediol, 1,2-undecanediol, 1,2-dodecanediol, 1,2-tridecanediol, 1,2-tetradecanediol and any mixtures thereof.

[0297] In a more particularly preferred variant, the detergent and cleaning compositions according to the invention comprising a mixture or combination of at least one first linear alkanediol and one or more second linear alkanediols comprise any of the following mixtures / combinations: ▪ A mixture containing 1,2-pentanediol and 2,3-pentanediol; or ▪A mixture containing 1,2-hexanediol and 2,3-hexanediol; or ▪A mixture comprising 1,2-heptanediol and 2,3-heptanediol; or ▪ A mixture containing 1,2-octanediol and 2,3-octanediol; or ▪A mixture comprising 1,2-nonanediol and 2,3-nonanediol; or ▪A mixture comprising 1,2-decanediol and 2,3-decanediol; or ▪ A mixture comprising 1,2-undecanediol and 2,3-undecanediol; or ▪A mixture comprising 1,2-dodecanediol and 2,3-dodecanediol; or ▪ A mixture comprising 1,2-tridecanediol and 2,3-tridecanediol; or ▪Contains a mixture of 1,2-tetradecanediol and 2,3-tetradecanediol.

[0298] In the homoalkanediol mixture, the first linear alkanediol and the second linear alkanediol have the same number of carbon atoms.

[0299] Particularly advantageous are mixtures comprising a combination of 1,2-pentanediol and 2,3-pentanediol or a combination of 1,2-heptanediol and 2,3-heptanediol or a combination of 1,2-octanediol and 2,3-octanediol and / or 3,4-octanediol.

[0300] A homoalkanediol mixture comprising 1,2-nonanediol and 2,3-nonanediol or a homoalkanediol mixture comprising 1,2-decanediol and 2,3-decanediol or a homoalkanediol mixture comprising 1,2-undecanediol and 2,3-undecanediol is most preferred due to its excellent enzyme stabilizing effect.

[0301] The above specified homoalkanediol mixtures according to the second aspect of the invention comprising 1,2-alkanediol and 2,3-alkanediol are characterized by a synergistic effect, i.e. the alkanediol mixtures stabilize enzymes in detergent and cleaning compositions in a synergistic manner compared to their respective single 1,2-alkanediol or 2,3-alkanediol species.

[0302] The synergistic effect or action of stabilizing the enzyme was found for a homogeneous mixture comprising 1,2-pentanediol and 2,3-pentanediol.

[0303] The synergistic effect of stabilizing the enzyme was also observed for a homogeneous mixture comprising 1,2-hexanediol and 2,3-hexanediol.

[0304] A homogenous mixture comprising 1,2-heptanediol and 2,3-heptanediol is particularly advantageous since it has a particularly pronounced synergistic effect on enzyme stabilization in detergent and cleaning compositions.

[0305] Alkanediol mixtures comprising 1,2-octanediol and 2,3-octanediol or 1,2-nonanediol and 2,3-nonanediol are particularly advantageous as these mixtures are effective in synergistically stabilizing enzymes in enzymatic detergent and cleaning compositions.

[0306] Furthermore, alkanediol mixtures comprising 1,2-decanediol and 2,3-decanediol or alkanediol mixtures comprising 1,2-undecanediol and 2,3-undecanediol synergistically stabilize enzymes in detergent and cleaning compositions.

[0307] The enzyme stabilizing effect also applies to alkanediol mixtures comprising 1,2-dodecanediol and 2,3-dodecanediol or to alkanediol mixtures comprising 1,2-tridecanediol and 2,3-tridecanediol.

[0308] The above-mentioned synergistic stabilizing effect on the performance of enzymes in detergent and cleaning compositions is particularly pronounced for homogeneous mixtures comprising 1,2-heptanediol and 2,3-heptanediol or comprising 1,2-octanediol and 2,3-octanediol or comprising 1,2-nonanediol and 2,3-nonanediol.

[0309] The above-specified homoalkanediol mixtures comprising a 1,2-alkanediol and a corresponding 2,3-alkanediol exhibit a marked synergistic activity and are significantly better than the corresponding 1,2-alkanediol or 2,3-alkanediol alone at the same concentration.

[0310] In particularly preferred variants, the detergent and cleaning compositions according to the second aspect of the invention comprising a mixture or combination of at least one first linear alkanediol and one or more second linear alkanediols may thus comprise any of the following mixtures / combinations: ▪ A mixture containing 1,2-hexanediol and 1,2-octanediol; or ▪ A mixture containing 1,2-hexanediol and 2,3-octanediol; or ▪ A mixture containing 1,2-octanediol and 2,3-hexanediol; or ▪ A mixture containing 1,2-octanediol and 2,3-heptanediol; or ▪ A mixture containing 1,2-pentanediol and 2,3-hexanediol; or ▪A mixture comprising 1,2-pentanediol and 2,3-heptanediol; or ▪ A mixture containing 1,2-pentanediol and 2,3-octanediol; or ▪A mixture comprising 1,2-pentanediol and 1,2-nonanediol; or ▪A mixture comprising 1,2-pentanediol and 2,3-nonanediol; or ▪A mixture comprising 1,2-heptanediol and 1,2-pentanediol; or ▪A mixture containing 1,2-heptanediol and 1,2-hexanediol; or ▪A mixture comprising 1,2-heptanediol and 1,2-octanediol; or ▪ A mixture containing 1,2-heptanediol and 2,3-octanediol; or ▪A mixture comprising 1,2-heptanediol and 1,2-nonanediol; or ▪A mixture comprising 1,2-heptanediol and 2,3-nonanediol; or ▪A mixture comprising 1,2-heptanediol and 1,2-decanediol; or ▪A mixture comprising 1,2-heptanediol and 1,2-undecanediol; or ▪A mixture comprising 1,2-heptanediol and 1,2-dodecanediol; or ▪Contains a mixture of 1,2-heptanediol and 1,2-tridecanediol.

[0311] The above-specified alkanediol mixture according to the invention comprising a first linear alkanediol and a second linear alkanediol is characterized by a synergistic effect, i.e. the alkanediol mixture stabilizes enzymes in detergent and cleaning compositions in a synergistic manner compared to the corresponding individual 1,2-alkanediol or 2,3-alkanediol substances.

[0312] In a particularly preferred variant, the detergent and cleaning compositions according to the invention comprising a mixture or combination of at least one first linear alkanediol and one or more second linear alkanediols may thus comprise the following mixtures / combinations: ▪Contains a mixture of 1,2-hexanediol and 1,2-octanediol.

[0313] Surprisingly, the alkanediol mixtures described have a particularly pronounced enzyme stabilizing effect.

[0314] Still more preferred is an enzyme stabilizer mixture wherein the at least first linear alkanediol is selected from 1,2-alkanediols having a lower number of 5 to 8 carbon atoms, and the one or more second alkanediols are selected from 1,2-alkanediols having a higher number of 9 to 14 carbon atoms.

[0315] Most preferred is an enzyme stabilizer mixture wherein the at least first linear alkanediol is selected from the group consisting of 1,2-pentanediol, 1,2-hexanediol, 1,2-heptanediol, 1,2-octanediol and any mixture thereof, and the one or more second alkanediols are selected from the group consisting of 1,2-nonanediol, 1,2-decanediol, 1,2-undecanediol, 1,2-dodecanediol, 1,2-tridecanediol, 1,2-tetradecanediol and any mixture thereof.

[0316] Most preferred is an enzyme stabilizer blend wherein the at least one first linear alkanediol is selected from the group consisting of 1,2-alkanediols having a lower number of carbon atoms of 5 to 8, i.e., 1,2-pentanediol, 1,2-hexanediol, 1,2-heptanediol, 1,2-octanediol, and any mixtures thereof, and the one or more second alkanediols are selected from the group consisting of 1,2-alkanediols having a higher number of carbon atoms of 9 to 13, i.e., 1,2-nonanediol, 1,2-decanediol, 1,2-undecanediol, 1,2-dodecanediol, 1,2-tridecanediol, and any mixtures thereof.

[0317] Surprisingly, such alkanediol mixtures of short-chain alkanediols and long-chain alkanediols have a particularly pronounced enzyme-stabilizing effect.

[0318] More preferred are alkanediol mixtures in which the difference between the number of carbon atoms of the at least first straight chain alkanediol and the number of carbon atoms of the one or more second alkanediols is at least 2 carbon atoms. In those alkanediol mixtures, short-chain and long-chain alkanediols are combined with each other, resulting in improved enzyme stability.

[0319] Still more preferred are enzyme stabilizer mixtures in which the difference between the number of carbon atoms of the at least first linear alkanediol and the number of carbon atoms of the one or more second alkanediols is at least 3 carbon atoms. With such alkanediol mixtures, the enzyme stabilization effect is particularly pronounced.

[0320] Such combinations may comprise any of the following mixtures / combinations: ▪ a combination of 1,2-pentanediol and one of 1,2-octanediol, 1,2-nonanediol, 1,2-decanediol, 1,2-undecanediol, 1,2-dodecanediol, 1,2-tridecanediol or 1,2-tetradecanediol; or ▪ A combination of 1,2-hexanediol and one of 1,2-nonanediol, 1,2-decanediol, 1,2-undecanediol, 1,2-dodecanediol, 1,2-tridecanediol, and 1,2-tetradecanediol; or ▪ A combination of 1,2-heptanediol and one of 1,2-decanediol, 1,2-undecanediol, 1,2-dodecanediol, 1,2-tridecanediol, and 1,2-tetradecanediol; and ▪ A combination of 1,2-octanediol and one of 1,2-undecanediol, 1,2-dodecanediol, 1,2-tridecanediol or 1,2-tetradecanediol.

[0321] In a further preferred variant according to the invention, in the detergent and cleaning compositions, the linear alkanediol is selected from the group consisting of 2,3-pentanediol, 2,3-hexanediol, 2,3-heptanediol, 2,3-octanediol, 2,3-nonanediol, 2,3-decanediol, 2,3-undecanediol, 2,3-dodecanediol, 2,3-tridecanediol, 2,3-tetradecanediol and mixtures thereof.

[0322] In a more preferred variant of the detergent and cleaning composition according to another aspect of the invention, the linear alkanediol is selected from the group consisting of 2,3-pentanediol, 2,3-hexanediol, 2,3-heptanediol, 2,3-octanediol, 2,3-nonanediol and mixtures thereof.

[0323] Surprisingly, the addition of 2,3-pentanediol, 2,3-hexanediol, 2,3-heptanediol and other 2,3-alkanediols (such as 2,3-octanediol, 2,3-nonanediol, 2,3-decanediol, 2,3-undecanediol, 2,3-dodecanediol, 2,3-tridecanediol and 2,3-tetradecanediol) to enzyme-containing detergent and cleaning compositions results in a significant stabilization of the enzymes compared to compositions without added 2,3-alkanediol.

[0324] According to a particularly preferred variant, the detergent and cleaning compositions according to the invention comprise at least one enzyme stabilizer selected from the group consisting of at least one linear 1,2-alkanediol having a carbon chain of 6 to 14 carbon atoms, or a mixture comprising at least one first linear 1,2-alkanediol having a carbon chain of 6 to 14 carbon atoms and one or more second linear 1,2-alkanediols having a carbon chain of 6 to 14 carbon atoms which are different from the first linear 1,2-alkanediol.

[0325] According to a particularly preferred variant, the detergent and cleaning compositions according to the invention comprise at least one enzyme stabilizer selected from the group consisting of at least one linear 1,2-alkanediol having a carbon chain of 7 to 14 carbon atoms, or a mixture comprising at least one first linear 1,2-alkanediol having a carbon chain of 7 to 14 carbon atoms and one or more second linear 1,2-alkanediols having a carbon chain of 7 to 14 carbon atoms which are different from the first linear 1,2-alkanediol.

[0326] Surprisingly, it has been found that these 1,2-alkanediols having a carbon chain of 6 to 14 or 7 to 14 carbon atoms are particularly effective enzyme stabilizers, which can also be effectively incorporated into a wide range of detergents and cleaning compositions. On the other hand, the improved enzyme stability in detergents and cleaning compositions leads to better cleaning performance after storage compared to detergents and cleaning compositions without the addition of such alkanediol stabilizers.

[0327] According to a particularly preferred variant, the detergent and cleaning compositions according to the invention comprise at least one enzyme stabilizer selected from the group consisting of at least one linear 1,2-alkanediol having a carbon chain of 5 to 8 carbon atoms, or a mixture comprising at least one first linear 1,2-alkanediol having a carbon chain of 5 to 8 carbon atoms and one or more second linear 1,2-alkanediols having a carbon chain of 5 to 8 carbon atoms which are different from the first linear 1,2-alkanediol.

[0328] In a still more preferred variant, the detergent and cleaning compositions according to the invention comprise at least one enzyme stabilizer selected from the group consisting of at least one linear 1,2-alkanediol having a carbon chain of 6 to 7 carbon atoms, or a mixture comprising at least one first linear 1,2-alkanediol having a carbon chain of 6 to 7 carbon atoms and one or more second linear 1,2-alkanediols having a carbon chain of 6 to 7 carbon atoms which are different from the first linear 1,2-alkanediol.

[0329] Surprisingly, it has been found that these short-chain 1,2-alkanediols are particularly suitable enzyme stabilizers and can also be effectively incorporated into a wide range of detergents and cleaning compositions. It has been found that these substances exhibit excellent enzyme stabilizing properties and significantly slow down the rate of enzyme deactivation during storage of detergents and cleaning compositions. Such detergents and cleaning compositions exhibit improved cleaning properties compared to detergents and cleaning compositions to which such substances are not added.

[0330] According to a particularly preferred variant, the detergent and cleaning compositions according to the invention comprise at least one enzyme stabilizer selected from the group consisting of at least one linear 1,2-alkanediol having a carbon chain of 9 to 14 carbon atoms, or a mixture comprising at least one first linear 1,2-alkanediol having a carbon chain of 9 to 14 carbon atoms and one or more second linear 1,2-alkanediols having a carbon chain of 9 to 14 carbon atoms which are different from the first linear 1,2-alkanediol.

[0331] In a more preferred variant, the detergent and cleaning compositions according to the invention comprise at least one enzyme stabilizer selected from the group consisting of at least one linear 1,2-alkanediol having a carbon chain of 10 to 13 carbon atoms, or a mixture comprising at least one first linear 1,2-alkanediol having a carbon chain of 10 to 13 carbon atoms and one or more second linear 1,2-alkanediols having a carbon chain of 10 to 13 carbon atoms different from the first linear alkanediol.

[0332] In a still more preferred variant, the detergent and cleaning compositions according to the invention comprise at least one enzyme stabilizer selected from the group consisting of at least one linear 1,2-alkanediol having a carbon chain of 11 to 12 carbon atoms, or a mixture comprising at least one first linear 1,2-alkanediol having a carbon chain of 11 to 12 carbon atoms and one or more second linear 1,2-alkanediols having a carbon chain of 11 to 12 carbon atoms different from the first linear alkanediol.

[0333] Surprisingly, it has been found that these long-chain 1,2-alkanediols are particularly suitable enzyme stabilizers and can also be effectively incorporated into a wide range of detergents and cleaning compositions. It has been found that these substances exhibit remarkable enzyme stabilizing properties and significantly slow the rate of enzyme inactivation during storage of detergents and cleaning compositions. Such detergents and cleaning compositions exhibit improved cleaning properties compared to detergents and cleaning compositions to which such substances are not added.

[0334] In a most preferred variant, the detergent and cleaning compositions according to the invention comprise at least one enzyme stabilizer selected from the group consisting of at least one linear 1,2-alkanediol having a log Pow value of ≤ 1, or a mixture comprising at least one first linear 1,2-alkanediol having a log Pow value of ≤ 1 and one or more second linear 1,2-alkanediols having a log Pow value of ≤ 1 different from the first linear 1,2-alkanediol.

[0335] The 1,2-alkanediol having a log Pow value of ≤ 1 is selected from the group consisting of 1,2-pentanediol (0.06), 1,2-hexanediol (0.58), 1,2-heptanediol (0.9) and any mixture thereof. The 1,2-alkanediol is more soluble in water.

[0336] The Pow value is the partition coefficient of a compound in a two-phase system consisting of two immiscible solvents, n-octanol and water, at equilibrium. Therefore, this value is a comparison of the solubility of the solute in these two liquids. Therefore, the partition coefficient measures the hydrophilicity or hydrophobicity of a chemical substance.

[0337] The logPow value is a constant defined as follows: Log Pow = log10 (partition coefficient) Partition coefficient, P = [n-octanol] / [water] where [ ] represents the concentration of solute in the organic and / or aqueous partitions.

[0338] The log Pow values ​​were determined at a standard temperature of 25°C.

[0339] A logPow value ≤ 1 means that the compound has a higher affinity for the aqueous phase (is more hydrophilic) and is therefore more soluble in water; a logPow value ≥ 1 indicates a higher concentration in the lipid phase (i.e., the compound is more lipophilic) and is therefore more soluble in fat-like solvents.

[0340] Surprisingly, it has been found that 1,2-alkanediols with a log Pow value of ≤ 1 are particularly suitable enzyme stabilizers, which can also be effectively incorporated into a wide range of detergents and cleaning compositions. Thus, detergents and cleaning compositions comprising 1,2-alkanediols with a log Pow value of ≤ 1 show improved enzymatic stability during storage compared to detergents and cleaning compositions without the addition of such 1,2-alkanediols.

[0341] In a still more preferred variant, the detergent and cleaning compositions according to the invention comprise at least one enzyme stabilizer selected from the group consisting of at least one linear 1,2-alkanediol having a log Pow value ≥ 1, or a mixture comprising at least one first linear 1,2-alkanediol having a log Pow value ≥ 1 and one or more second linear 1,2-alkanediols having a log Pow value ≥ 1 which are different from the first linear 1,2-alkanediol.

[0342] The 1,2-alkanediol having a log Pow value of ≥ 1 is selected from the group consisting of 1,2-octanediol (logPow = 2.1), 1,2-nonanediol, 1,2-decanediol, 1,2-undecanediol, 1,2-dodecanediol, 1,2-tridecanediol, 1,2-tetradecanediol and any mixture thereof. The 1,2-alkanediol is more soluble in fat-like solvents, such as n-octanol.

[0343] Surprisingly, it has been found that 1,2-alkanediols with a log Pow value of ≥ 1 are particularly suitable enzyme stabilizers, which can also be effectively incorporated into a wide range of detergents and cleaning compositions. Thus, detergents and cleaning compositions comprising 1,2-alkanediols with a log Pow value of ≥ 1 show improved enzymatic stability during storage compared to detergents and cleaning compositions without the addition of such 1,2-alkanediols.

[0367] Likewise, for the alkanediol mixture, the ratio of the first linear alkanediol to the second alkanediol or the ratio range described above is also applicable.

[0368] Preferred variants according to the invention also encompass a mixture comprising 1,2-hexanediol as the first linear alkanediol and 1,2-octanediol as the second linear alkanediol in a ratio ranging from 50:50 to 99.9:0.1, preferably in a ratio ranging from 75:25 to 99:1, more preferably in a ratio ranging from 80:20 to 98:2, or still more preferably in a ratio ranging from 90:10 to 95:5.

The improved enzyme stability in detergents and cleaning compositions in turn leads to better cleaning performance even after storage compared to detergents and cleaning compositions without the addition of such enzyme stabilizer mixtures.

[0392] Surprisingly, even a synergistic enzyme stabilizing effect could be observed for the mixture compared to the stabilizing effect of the individual enzyme stabilizers.

[0393] Most preferably, the detergent and cleaning compositions according to the present invention comprise a mixture of enzyme stabilizers comprising a combination of 1,2-alkanediol and 4-hydroxyacetophenone selected from the group consisting of: ▪Include(b III ) a mixture of 4-hydroxyacetophenone and 1,2-pentanediol; ▪Include(b III ) a mixture of 4-hydroxyacetophenone and 1,2-hexanediol; ▪Include(b III ) a mixture of 4-hydroxyacetophenone and 1,2-heptanediol; ▪Include(b III ) a mixture of 4-hydroxyacetophenone and 1,2-octanediol; ▪Include(b III ) a mixture of 4-hydroxyacetophenone and 1,2-nonanediol; ▪Include(b III ) a mixture of 4-hydroxyacetophenone and 1,2-decanediol; ▪Include(b III ) a mixture of 4-hydroxyacetophenone and 1,2-undecanediol; ▪Include(b III) a mixture of 4-hydroxyacetophenone and 1,2-dodecanediol; ▪Include(b III ) a mixture of 4-hydroxyacetophenone and 1,2-tridecanediol; ▪Include(b III ) a mixture of 4-hydroxyacetophenone and 1,2-tetradecanediol; The study found that an enzyme stabilizer mixture comprising a combination of 4-hydroxyacetophenone and 1,2-alkanediol exhibits an excellent synergistic enzyme stabilization effect and significantly slows down the enzyme deactivation rate of detergents and cleaning compositions during storage.

[0437] Additional enzyme stabilizers / components (d1, d2, d3, d) The enzymatic detergent and cleaning composition according to the first and second aspects of the present invention optionally comprises at least one additional enzyme stabilizer (d1, d2, d3, d) which is different from the enzyme stabilizer (b1, b2, b3, b) to further stabilize the enzyme in the detergent and cleaning composition without loss of performance (i.e. retention of proteolytic activity or enzyme retention). The enzyme is stabilized by the additional enzyme stabilizer by physical protection with the aid of a protective layer.

[0438] Negatively charged anionic surfactants capture Ca and / or Mg ions from the washing liquid and form a complex. The formation of this complex leads to a reduction in washing performance. In order to prevent the formation of this complex, chelating agents (such as EDTA, HEDP, etc.) are added to detergents and cleaning compositions. However, these chelating agents not only complex the Ca ions and / or Mg ions from the washing liquid, but also capture the Ca ions and Mg ions from the surface of the enzyme, which in turn leads to denaturation. Therefore, the enzyme loses their active form, which in turn leads to a reduction in enzymatic activity. Therefore, enzyme stabilizers are added to detergents and cleaning compositions, which protect the enzyme. Therefore, chelating agents can only capture Ca ions and / or Mg ions from the washing liquid, but can no longer capture Ca ions and / or Mg ions from the surface of the enzyme. Therefore, enzyme activity can be maintained by adding enzyme stabilizers.

[0439] The formulation of detergents and cleaning compositions can vary depending upon the specific enzymes used.

[0440] The enzymes used herein are stabilized by the presence of water-soluble sources of calcium and / or magnesium ions in the finished detergents and cleaning compositions, which provide such ions to the enzymes. Calcium ions are generally slightly more effective than magnesium ions, and are preferred herein if only one type of cation is used. Typical detergents and cleaning compositions (especially liquids) contain 1 to 30 millimoles, preferably 2 to 20 millimoles, more preferably 5 to 15 millimoles, and most preferably 8 to 12 millimoles of calcium ions per liter of finished composition.

[0441] It should be understood that the above-mentioned levels of calcium and / or magnesium ions are sufficient to provide enzyme stability. More calcium and / or magnesium ions can be added to the composition to provide an additional measure of grease removal performance. Therefore, as a general suggestion, the composition herein will typically contain 0.01% by weight to 2% by weight of a water-soluble source of calcium ions or magnesium ions or both. Of course, this amount can vary with the amount and type of enzyme used in the composition.

[0442] Additional enzyme stabilization may be provided by the presence of various other stabilizers disclosed in the art, particularly borate materials, see US 4,537,706, the entire contents of which are incorporated herein.

[0443] One group of stabilizers is a reversible protease inhibitor. Benzamidine hydrochloride, borax, boric acid, boronic acid or their salts or esters are often used for this purpose, particularly including derivatives with aromatic groups. Typically, the amount of such enzyme stabilizers in the composition is 0.05% to 5%, more preferably 0.075% to 3% (calculated based on boric acid) by weight of boric acid or other borate compounds capable of forming boric acid in the composition. Boric acid is preferred, but other compounds such as boric oxide, borax and other alkali metal borates (e.g., sodium orthoborate, sodium metaborate and sodium pyroborate and sodium pentaborate) are also suitable. Substituted boric acids (e.g., phenylboric acid, butaneboric acid and p-bromophenylboric acid) can also be used to replace boric acid.

[0444] Peptide aldehydes, i.e. oligopeptides with a reduced C-terminus, in particular oligopeptides from 2 to 50 monomers, or bisulfite adducts thereof are also useful for this purpose. Peptide reversible protease inhibitors include, but are not limited to, ovomucoid and leupeptin. Specific reversible peptide inhibitors and specific peptide inhibitors for the protease subtilisin and fusion proteins from proteases are also suitable for this purpose.

[0445] Further enzyme stabilizers are amino alcohols such as monoethanolamine, diethanolamine, triethanolamine and propanolamine and mixtures thereof, aliphatic carboxylic acids up to C12 such as succinic acid, other dicarboxylic acids or salts of the abovementioned acids.

[0446] End-capped fatty acid amide alkoxylates are also suitable for this purpose.

[0447] Preferably, the additional enzyme stabilizers (d1, d2, d3, d) in the detergent and cleaning compositions according to the invention are selected from the group consisting of: polyols, such as glycols such as monopropylene glycol, glycerol, mannitol, isomalt, sorbitol, xylitol, threitol, erythritol, arabitol; amino alcohols, such as monoethanolamine, diethanolamine, triethanolamine and monopropanolamine, dipropanolamine, tripropanolamine; aliphatic carboxylic acids up to C12, such as succinic acid and its salts; dicarboxylic acids and their salts; blocked fatty acid amide alkoxylates; salts, preferably calcium and magnesium salts, such as calcium chloride, calcium formate, magnesium chloride, magnesium formate; reversible enzyme inhibitors, such as borate-containing compositions such as 4-FBPA, boron-free inhibitors such as disubstituted alaninamides, sodium formate; and any mixtures thereof.

[0448] Most preferably, the additional enzyme stabilizers (d1, d2, d3, d) in the detergent and cleaning compositions according to the invention are selected from the group consisting of calcium chloride, calcium formate, magnesium chloride, magnesium formate and any mixtures thereof.

[0449] Furthermore, by adding the additional enzyme stabilizer, the negatively charged anionic surfactants can be prevented from forming complexes with Ca ions and / or Mg ions from the wash liquor, thereby preventing a reduction or loss of their washing performance.

[0450] Preferably, at least one enzyme (a1, a2, a3, a) is added to the detergent and cleaning compositions according to the first and second aspects of the invention as an enzyme formulation mixed with at least one additional enzyme stabilizer (d1, d2, d3, d) (as described above) and optionally a buffer or the like.

[0451] In a further preferred variant, at least one enzyme (a1, a2, a3, a) is added to the detergent and cleaning compositions according to the invention as an enzyme formulation in admixture with one or more further enzyme stabilizers (d1, d2, d3, d) and with a specific type of enzyme stabilizer (b1, b2, b3, b) such as alkanediols, caprylic acid glyceride, 4-hydroxyacetophenone, ethylhexylglycerol, tropolone or a mixture of said enzyme stabilizers as defined herein, which is different from the further enzyme stabilizers and optionally a buffer etc.

[0452] Surprisingly, it has been found that the addition of an enzyme stabilizer (b1, b2, b3, b) as defined herein enhances or promotes the enzyme stabilizing effect of another enzyme stabilizer (d1, d2, d3, d3).

[0453] Unexpectedly, the combination of enzyme stabilizer (b1, b2, b3, b) and additional enzyme stabilizer (d1, d2, d3, d) produces a synergistic enzyme stabilizing effect in enzyme-containing detergent and cleaning compositions compared to the use of a single enzyme stabilizer (b1, b2, b3, b) or the use of a single additional enzyme stabilizer (d1, d2, d3, d).

[0454] A particular promoting effect can be observed for the combined use of enzyme stabilizers (b1, b2, b3, b) such as alkanediols having a carbon chain of 5 to 14 carbon atoms, caprylic acid glyceride, 4-hydroxyacetophenone, ethylhexylglycerol, tropolone or a mixture of said enzyme stabilizers with enzyme stabilizers (d1, d2, d3, d) comprising calcium chloride, calcium formate, magnesium chloride, magnesium formate and any mixture thereof.

[0455] For the detergent and cleaning compositions and enzyme formulations according to the invention, the list of enzyme stabilizers (b1, b2, b3, b) described herein can be combined arbitrarily with the list of further enzyme stabilizers (d1, d2, d3, d) described herein.

[0456] A significant synergistic enzyme stabilizing effect is observed when one or more of the following enzyme stabilizers (b1, b2, b3, b) are used in combination with one or more additional enzyme stabilizers (d1, d2, d3, d) as defined herein, preferably calcium chloride, calcium formate, magnesium chloride, magnesium formate and any mixtures thereof: ▪1,2-Pentanediol; ▪1,2-Hexanediol; ▪1,2-Heptanediol; ▪1,2-Octanediol; ▪1,2-nonanediol; ▪1,2-Decanediol; ▪1,2-Undecanediol; ▪1,2-Dodecanediol; ▪1,2-Tridecanediol; ▪1,2-Tetradecanediol; ▪Glyceryl caprylate; ▪4-Hydroxyacetophenone; ▪Ethylhexylglycerin; ▪Treptolide; ▪A mixture containing 1,2-hexanediol and 1,2-octanediol; ▪ A mixture containing 1,2-hexanediol and 1,2-octanediol and tropolone; and ▪Contains a mixture of 4-hydroxyacetophenone and 1,2-octanediol.

[0457] Thus, the combined addition of an enzyme stabilizer as defined herein with an additional enzyme stabilizer results in improved enzyme stability compared to the enzyme stabilizing effect of a single agent. Detergents and cleaning compositions comprising the mixture show improved cleaning performance compared to detergents and cleaning compositions without the addition of such a mixture.

[0458] Optional additional components In the context of the present invention, it is also possible and advantageous in some cases to combine the detergent and cleaning composition according to the first aspect or the second aspect of the present invention with other active substances and / or additives to obtain ready-to-use compositions or formulations. Active ingredients provide desired properties and functions for the detergent and cleaning composition according to the present invention. The term "functional ingredient" or "functional additive" includes ingredients that provide beneficial properties in specific uses. Some specific examples of functional ingredients are discussed in more detail below. However, various other functional ingredients may also be used.

[0461] Chelating agents / sequestrants Detergents and cleaning compositions disclosed herein may optionally include one or more chelating agents capable of complexing iron, manganese and / or calcium ions. This additionally allows softening of water. In addition, negatively charged anionic surfactants capture Ca and / or Mg ions from the washing solution and form complexes. The formation of this complex results in a reduction in washing performance. In order to prevent the formation of this complex, a chelating agent as described below is also added to the detergent and cleaning compositions. Therefore, the addition of a chelating agent does not reduce the performance of the anionic surfactant in the detergent and cleaning compositions.

[0462] The chelating agents may be present in acid or salt form, including alkali metal, ammonium and substituted ammonium salts thereof and mixtures thereof.

[0463] Preferably, the chelating agent is selected from the group consisting of aminocarboxylates, phosphonates or mixtures thereof.

Among the hydroxyalkane phosphonates, 1- Hydroxyethane-1,1-diphosphonate (HEDP) is of particular importance. The chelating agent may contain nitrogen, such as in EDTA, NTA, DTPA, PDTA, GLDA, MGDA, EDDS, EDTMP, EDTMPA and DTPMP or ASMA, ASDA, ASMP, IDA, SMAS, SEAS, SMGL, SEGL, MIDA, a-ALDA, SEDA, ISDA, PHDA, ANDA, SLDA, TUDA, SMDA, HEDTA, DEG, ATMP or mixtures thereof.

The chelating agents may be present in their acid form or salt form, preferably, the chelating agents may be present in the form of sodium, ammonium or potassium salts.

[0469] Particularly preferred chelating agents include diethylenetriaminepentaacetic acid (DTPA), ethylenediamine-N,N'-disuccinic acid (EDDS) and 1,1-hydroxyethanediphosphonic acid (HEDP) or alkali metal, potassium, alkaline earth metal, ammonium or substituted ammonium salts thereof, or mixtures thereof. The most preferred chelating agents are phosphonates. Phosphonate chelating agents include HEDP in acid form or in salt form with alkali metal, potassium, alkaline earth metal, ammonium or substituted ammonium.

[0470] Most preferred are the following chelating agents: GLDA, MGDA, sodium citrate, HEDP and any mixtures thereof.

[0471] In the detergent and cleaning compositions according to the present invention, the chelating agent is generally present in an amount of 0.1 to 10.0 wt %, preferably 0.1 to 5.0 wt %, and more preferably 0.1 to 3.0 wt %, based on the total weight of the composition.

[0472] Preferably, the detergent and cleaning compositions according to the invention comprise at least 0.2 wt.-% chelating agent, also preferably at least 0.3 wt.-%, also preferably at least 0.5 wt.-%, most preferably at least 0.6 wt.-%, but typically no more than 3 wt.-%, also preferably no more than 2 wt.-%, most preferably no more than 1 wt.-% chelating agent, based on the total weight of the composition.

[0473] However, in some automatic dishwashing gels, the amount of GLDA may be from 30% to 40% by weight, based on the total weight of the composition.

[0474] Antimicrobial Agents Detergents and cleaning compositions may also contain one or more antimicrobial agents.

[0475] In the context of the present invention, the term "antimicrobial component" refers to a group of substances, in particular agents that kill microorganisms (such as bacteria, yeasts and / or fungi) or prevent or inhibit their growth, which prevents the product from being contaminated by microorganisms. Without the addition of such agents, the product would deteriorate, which can be manifested by odor changes, discoloration, mold growth, gas formation, emulsion separation or viscosity changes, making the product unacceptable to consumers.

[0476] Suitable antimicrobial agents include, but are not limited to, antimicrobial classes such as phenols, quaternary ammonium compounds, metal derivatives, amines, alkanolamines, nitro derivatives, analides, organic sulfur and sulfur-nitrogen compounds, and various compounds. Exemplary phenolic agents include pentachlorophenol, o-phenylphenol, phenoxyethanol. Exemplary quaternary ammonium antimicrobial agents include benzalkonium chloride, cetylpyridinium chloride, amines, and nitro-containing antimicrobial compositions such as hexahydro-1,3,5-tris(2-hydroxyethyl)-s-triazine, dithiocarbamates such as sodium dimethyldithiocarbamate, and various other materials with antimicrobial properties known in the art.

[0477] In a preferred variant according to the invention, the detergent and cleaning composition is further combined with benzyl alcohol, methylbenzyl alcohol, phenoxyethanol and any mixture thereof. Said substances have a broad spectrum of activity against microorganisms and are added to detergent compositions to inhibit microbial spoilage and thus for stabilization purposes.

[0478] In particular, antimicrobial agents are added to liquid detergents due to their higher water content, which makes such compositions susceptible to microbial infestation and growth.

[0479] If an antimicrobial agent is included in the detergent and cleaning compositions of the present invention, the amount of the antimicrobial agent is preferably between about 0.0001 wt % and about 15 wt %, particularly in an amount of 0.001 wt % to 10 wt %, most particularly in an amount of 0.001 wt % to 5 wt %, based on the total weight of the composition.

[0480] Enzyme is usually incorporated into detergents and cleaning compositions according to the present disclosure in an amount sufficient to produce effective cleaning during the washing process. Effective amount for cleaning refers to an amount that produces a clean, sanitary and preferably non-corrosive appearance for the material being cleaned (particularly for medical or dental devices or apparatus). Effective amount for cleaning can also refer to an amount that produces a cleaning, stain removal, decontamination, whitening and deodorizing or refreshing improvement effect for a substrate (such as a medical or dental device or apparatus, etc.). This cleaning effect can be achieved with an amount of enzyme as low as about 0.02% by weight of the detergent and cleaning composition.

[0481] In the detergents and cleaning compositions of the present disclosure, suitable cleaning can typically be achieved when the enzyme is present at about 0.0001% to about 35% by weight; preferably about 2% to about 15% by weight; preferably about 3% to about 10% by weight; preferably about 4% to about 8% by weight; preferably about 4%, about 5%, about 6%, about 7% or about 8% by weight. Typically, higher enzyme levels are desirable in highly concentrated cleaning formulations.

[0482] In the detergent and cleaning compositions of the present invention, when the enzyme is present in an amount of 0.0001% by weight to 5% by weight, based on the total weight of the composition, suitable cleaning can be achieved.

More preferably, based on the total weight of the composition, the detergent and cleaning compositions according to the present invention comprise an enzyme in an amount of 0.001% by weight to 3% by weight. Most preferably, based on the total weight of the composition, the enzyme is present in the detergent and cleaning compositions in an amount of 0.01% by weight to 2% by weight. Further preferably, based on the total weight of the composition, the enzyme is present in the detergent and cleaning compositions in an amount of 0.05% by weight to 2% by weight.

[0483] Typically, the enzyme is present in the detergent and cleaning compositions according to the invention in an amount of 0.05 to 2.0 wt %. Typically, proteases and amylases are used in higher concentrations in detergents and cleaning compositions, i.e., the amount of proteases is 0.4 to 1.5 wt % and the amount of amylases is 0.05 to 0.6 wt %, based on the total weight of the composition.

[0484] For enzyme mixtures, the above amounts relate to the total enzyme content in the mixture, ie the amount is the sum of the contents of all enzymes in the mixture.

[0485] Based on the gross weight of the composition, 1,2-heptanediol (b1) or 2,3-heptanediol (b2) or a mixture (b3) comprising 1,2-heptanediol and 2,3-heptanediol according to the first aspect of the present invention is present in detergents and cleaning compositions in an amount of 0.001% by weight to 15.0% by weight. In a preferred variant, based on the gross weight of the composition, detergents and cleaning compositions comprise 1,2-heptanediol (b1) or 2,3-heptanediol (b2) or a mixture (b3) comprising 1,2-heptanediol and 2,3-heptanediol in an amount of 0.01% by weight to 10.0% by weight. In a more preferred variant, based on the gross weight of the composition, 1,2-heptanediol (b1) or 2,3-heptanediol (b2) or a mixture (b3) comprising 1,2-heptanediol and 2,3-heptanediol is advantageously used in detergents and cleaning compositions in an amount of 0.1% by weight to 5.0% by weight. In still more preferred variants, 1,2-heptanediol (b1) or 2,3-heptanediol (b2) or a mixture (b3) comprising 1,2-heptanediol and 2,3-heptanediol is advantageously used in detergents and cleaning compositions in an amount of 0.3% to 3.0% by weight, based on the total weight of the composition. In the most preferred variants, 1,2-heptanediol (b1) or 2,3-heptanediol (b2) or a mixture (b3) comprising 1,2-heptanediol and 2,3-heptanediol is advantageously used in detergents and cleaning compositions in an amount of 0.5% to 1.0% by weight, based on the total weight of the composition.

[0486] For the heptanediol mixture (b3), the above amounts relate to the total content of 1,2-heptanediol and 2,3-heptanediol in the mixture, ie the amount is the sum of the contents of 1,2-heptanediol and 2,3-heptanediol in the mixture.

[0487] Based on the gross weight of the composition, at least one enzyme stabilizer (b) according to the present invention is present in detergents and cleaning compositions in an amount of 0.001% by weight to 15.0% by weight. In preferred variants, based on the gross weight of the composition, detergents and cleaning compositions comprise at least one enzyme stabilizer (b) in an amount of 0.01% by weight to 10.0% by weight. In more preferred variants, based on the gross weight of the composition, at least one enzyme stabilizer (b) is advantageously used in detergents and cleaning compositions in an amount of 0.1% by weight to 5.0% by weight. In still more preferred variants, based on the gross weight of the composition, at least one enzyme stabilizer (b) is advantageously used in detergents and cleaning compositions in an amount of 0.3% by weight to 3.0% by weight. In most preferred variants, based on the gross weight of the composition, at least one enzyme stabilizer (b) is advantageously used in detergents and cleaning compositions in an amount of 0.5% by weight to 1.0% by weight.

[0488] For an alkanediol mixture comprising at least one first linear alkanediol and one or more second linear alkanediols, the above amounts relate to the total content of the first linear alkanediol and the second linear alkanediol in the mixture, i.e. the amount is the sum of the contents of the first linear alkanediol and the second linear alkanediol in the mixture.

[0489] For an enzyme stabilizer mixture comprising two or more enzyme stabilizers, the above amounts relate to the total content of enzyme stabilizers in the mixture, ie the amount is the sum of the contents of the individual enzyme stabilizers in the mixture.

[0490] In particularly preferred variants according to the first aspect of the invention, the detergent and cleaning compositions comprise 2,3-heptanediol or 2,3-heptanediol comprising a mixture (b3) of 1,2-heptanediol and 2,3-heptanediol in an amount of 0.001% to 15.0% by weight, preferably in an amount of 0.01% to 10.0% by weight, more preferably in an amount of 0.1% to 5.0% by weight, still more preferably in an amount of 0.3% to 3.0% by weight, and most preferably in an amount of 0.5% to 1.0% by weight, based on the total weight of the composition.

[0491] Even more preferably, the detergent and cleaning compositions comprise 2,3-heptanediol or 2,3-heptanediol comprising a mixture (b3) of 1,2-heptanediol and 2,3-heptanediol in an amount of 0.001 to 0.5 wt.-%, preferably in an amount of 0.005 to 0.1 wt.-%, and most preferably in an amount of 0.01 to 0.075 wt.-%, based on the total weight of the composition or household care product.

[0492] In particularly preferred variants according to the invention, the detergent and cleaning compositions comprise 2,3-alkanediol as linear alkanediol, or 2,3-alkanediol comprising a mixture of at least one first linear alkanediol and one or more second linear alkanediols, in an amount of 0.001% to 15.0% by weight, preferably in an amount of 0.01% to 10.0% by weight, more preferably in an amount of 0.1% to 5.0% by weight, still more preferably in an amount of 0.3% to 3.0% by weight, and most preferably in an amount of 0.5% to 1.0% by weight, based on the total weight of the composition or household care product.

[0493] Even more preferably, the detergent and cleaning compositions comprise 2,3-alkanediol as the linear alkanediol, or 2,3-alkanediol comprising a mixture of at least one first linear alkanediol and one or more second linear alkanediols, in an amount of 0.001 wt.-% to 0.5 wt.-%, preferably in an amount of 0.005 wt.-% to 0.1 wt.-%, and most preferably in an amount of 0.01 wt.-% to 0.075 wt.-%, based on the total weight of the composition or home care product.

[0494] Typically, at least one surfactant is present in the detergent and cleaning compositions according to the present invention in an amount of more than 3% by weight, based on the total weight of the composition. Preferably, the surfactant is present in an amount of 4% to 90% by weight, based on the total weight of the composition. More preferably, the detergent and cleaning compositions according to the present invention comprise a surfactant in an amount of 10% to 60% by weight, still more preferably in an amount of 20% to 50% by weight, and most preferably in an amount of 30% to 40% by weight, based on the total weight of the composition.

[0495] In contrast, the light-duty composition according to the first and second aspects of the invention comprises at least one surfactant in an amount of more than 3% to 40% by weight, based on the total weight of the composition. Preferably, the surfactant is present in an amount of 4% to 30% by weight, based on the total weight of the composition. The dish cleaning and / or rinsing composition according to the invention comprises a surfactant in an amount of 5% to 20% by weight, and preferably in an amount of 6% to 15% by weight, based on the total weight of the composition.

[0496] At least one additional enzyme stabilizer is present in the detergent and cleaning compositions according to the first and second aspects of the invention in an amount of 0.0001% to 5% by weight, based on the total weight of the composition. Preferably, the additional enzyme stabilizer is present in an amount of 0.001% to 4% by weight, based on the total weight of the composition. Most preferably, the detergent and cleaning compositions according to the first and second aspects of the invention comprise additional enzyme stabilizers in an amount of 0.01% to 3% by weight, based on the total weight of the composition.

[0497] Surprisingly, it has been found that the detergents and cleaning compositions according to the present invention have excellent enzyme stability. The more stable the enzymes in the composition, the longer they are effective in removing dirt and stains. Thus, the enzymatic effect of the detergents and cleaning compositions according to the present invention increases over time compared to detergents and cleaning compositions to which the enzyme stabilizer of the present invention is not added.

[0498] In particular, it has been found that the addition of an effective amount of a specific type of enzyme stabilizer (such as alkanediol, caprylic acid glyceride, 4-hydroxyacetophenone, ethylhexylglycerol, tropolone or a mixture of said enzyme stabilizers, as defined in detail herein) to detergents and cleaning compositions comprising an enzyme or an enzyme mixture results in excellent enzyme stabilization properties as demonstrated in the following examples, and significantly slows the rate of enzyme inactivation of the detergents and cleaning compositions during storage. Such detergents and cleaning compositions exhibit improved cleaning properties compared to detergents and cleaning compositions to which such enzyme stabilizers are not added.

[0499] It has been unexpectedly observed that the addition of an enzyme stabilizer or enzyme stabilizing mixture as described above can stabilize enzymes in detergent and cleaning compositions. Without being bound by theory, it is hypothesized that with the addition of an enzyme stabilizer as described herein, a protective layer, particularly preferably a coating, is created around the enzyme / enzymes to keep them stable or resistant to irritating ingredients within detergent and cleaning compositions, as hypothesized for the known enzyme stabilizer ethylene glycol.

[0500] In particular, adding an enzyme stabilizer as described above or an enzyme stabilizing mixture to a detergent and cleaning composition containing an enzyme can maintain the activity of the enzyme for a long time during the storage period of the composition. The enzyme stabilizer according to the present invention has a positive impact on enzyme performance because it significantly delays the rate of enzyme inactivation during storage. Therefore, the activity of the enzyme remains higher than the activity of the detergent and cleaning composition that does not contain this enzyme stabilizer of the present invention. The more stable the enzyme is, the longer their effective time in removing dirt, protein, starch and fat, etc. Therefore, compared with detergents and cleaning compositions that do not contain enzyme stabilizers or enzyme stabilizing mixtures, detergents and cleaning compositions disclosed herein show better cleaning performance after storage.

[0501] Furthermore, by adding such enzyme stabilizers as defined herein, it is even possible to improve the enzyme stabilizing effect of further enzyme stabilizers added to detergent and cleaning compositions.

[0502] Thus, enzymatic stabilization allows detergents and cleaning compositions to be stored without or at least with greatly reduced enzymatic degradation and deterioration. Surprisingly, using the enzyme stabilizer according to the invention, the storage life of detergents and cleaning compositions can be extended without or with less enzyme inactivation compared to compositions without the enzyme stabilizer of the invention.

[0503] Beneficially, the enzymatic detergents and cleaning compositions according to the present invention exhibit storage stability while retaining enzymatic efficacy compared to detergents and cleaning compositions that do not contain the enzyme stabilizers of the present invention.

[0504] Further, the enzymatic detergents and cleaning compositions according to the present invention exhibit improved storage stability, such that they can be stored at temperatures above standard room temperature (25°C), preferably at least 30°C, more preferably at least 35°C, for at least 2 weeks, more preferably at least 4 weeks, still more preferably at least 6 weeks, most preferably at least 8 weeks, and most preferably at least 12 weeks, while retaining the enzymatic efficacy, and thus resulting in better cleaning performance.

[0505] Surprisingly, the enzyme stabilizer according to the invention provides enzyme stability for detergents and cleaning compositions in a wide pH range of pH 3 to pH 12. Thus, the enzyme stabilizer according to the invention allows stabilization of enzymes in a variety of detergents and cleaning compositions with different pH values ​​in the acidic, alkaline or neutral pH range. This is particularly advantageous for detergents and cleaning compositions with acidic or alkaline pH values, such as bathroom cleaners or kitchen cleaners, in which enzymes tend to be inactivated or unstable.

[0506] Without the use of enzyme stabilizers as described herein, the enzymatic stability in detergents and cleaning compositions comprising enzymes as defined herein will decrease during storage, so that the cleaning performance of the detergents and cleaning compositions will decrease upon use.

[0507] The enzyme stabilization effect is demonstrated in the following examples by actual washing / cleaning tests. As shown in the present disclosure, use solutions produced by detergents and cleaning compositions according to the present invention remain active for a much longer period of time than detergents and cleaning compositions without the addition of the enzyme stabilizer of the present invention.

[0508] This enzyme stabilization effect results in a more effective composition due to prolonged soil or stain removal activity.

[0509] Advantageously, the improved stability further allows for reduced use of enzymes, enzyme stabilizers, or some other ingredients commonly used in detergent and cleaning compositions. Due to the excellent stability of enzymes in the detergent and cleaning compositions of the present disclosure, the compositions can reduce the amount of enzymes used without sacrificing cleaning performance.

[0510] Due to the excellent stability of enzymes in the detergents and cleaning compositions of the present disclosure, the compositions are likely to have reduced or even no other enzyme stabilizers, such as glycerol, or other ingredients commonly used in existing detergents and cleaning compositions. Some stabilizers may be difficult to include in detergents and cleaning compositions, or may cause undesirable reactions with other ingredients. Some stabilizers cause health / safety / labeling issues in concentrated compositions (e.g., undesirable GHS labeling icon warnings). An additional advantage is that no or reduced amounts of other enzyme stabilizers are used to produce the detergents and cleaning compositions disclosed herein.

[0511] Thus, in preferred variants, the detergent and cleaning compositions according to the invention have fewer further components or are even free of additional enzyme stabilizers other than those described above, such as reduced amounts of ingredients comprising borates.

[0512] According to a further aspect of the present invention, the detergent and cleaning compositions according to the first and second aspects of the present invention are used as such, or are used to prepare detergent and cleaning products.

[0513] Enzymatic detergents and cleaning compositions or products as described herein can be used in a variety of cleaning methods. As used herein, the term "cleaning" refers to performing, promoting or assisting in stain removal, bleaching, microbial population reduction, disinfection, etc. Preferably, the enzymatic detergents and cleaning compositions or products can be used for textile cleaning, laundry washing, dishwashing, fabric care, for household, institutional and industrial hard surface cleaning, such as utensils or other surfaces, cleaning medical and dental instruments, etc.

[0514] Preferably, the enzymatic detergents and cleaning compositions or products can be used to clean, wash or pre-soak medical or dental devices, instruments or equipment, including any of the various medical or dental instruments or equipment that can benefit from cleaning with an enzymatic cleaning composition. Exemplary medical and dental instruments and devices include instruments, devices, tools, utensils, equipment and equipment used in medicine or dentistry, including instruments, devices, tools, utensils, equipment and equipment that can be cold sterilized, soaked or washed and then heat sterilized. Medical and / or dental instruments may be contaminated with blood, mammalian tissue (including but not limited to human tissue) or other foreign matter.

[0515] Suitable examples of detergents and cleaning compositions or products include heavy-duty detergents, color-protecting detergents, light-duty detergents, all-purpose detergents, fabric softeners, fabric wash fragrances, scented washes, laundry wipes, stain and / or soil removers (pre-stain, Vanish type), degreasing cleaners, washing machine cleaners, all-purpose cleaners, hand dishwashing detergents, automatic machine dishwashing detergents, hard surface cleaners, glass and mirror cleaners, cleaning wipes, kitchen cleaners, cookware cleaners, oven cleaners, floor cleaners, wood floor cleaners, carpet cleaners, bathroom and shower cleaners, toilet cleaners, grout cleaners, disinfectants, drain unclogging agents, toilet seat clog gels, air fresheners, furniture polishes, car shampoos, medical cleaning products, and the like.

[0516] The above-mentioned detergent and cleaning compositions or products refer to compositions or products in liquid, solid, tablet, encapsulated, diluted or concentrated form and optionally in two-compartment or multi-compartment form.

[0517] As used herein, liquids include free-flowing liquids as well as pastes, gels, foams and mousses. Non-limiting examples of liquids include light-duty and heavy-duty liquid detergents and cleaning compositions, fabric enhancers, detergent gels commonly used in laundry, bleaching agents and laundry additives. Gases (e.g., suspended bubbles) or solids (e.g., particles) may be contained in the liquid.

[0518] As used herein, solid includes powder, flakes, granules, pellets, tablets, microcapsules, beads, noodles, pearlized balls, pastilles, pucks, agglomerates, bricks, blocks, or another solid form known to those skilled in the art.

[0519] Solid detergent and cleaning compositions or products can be provided as pressed solid blocks, cast solid blocks, extruded pellets or blocks or tablets. In addition, solid detergent compositions or products can be provided in the form of unit doses. Unit doses refer to solid detergent and cleaning composition units that are sized so that all units are used during a single wash cycle.

[0520] Solid detergents and cleaning compositions or products can also be provided in the form of multiple-use (e.g., multi-use) solids such as blocks or multiple pellets, and can be repeatedly used to produce aqueous use solutions of detergent compositions for multiple cycles or a predetermined number of distribution cycles. Multiple-use solid detergent compositions can be reused to generate aqueous detergent compositions, such as use solutions, for multiple washing cycles. The pressed solid detergent blocks are adapted to provide stability so that the reactive components in the composition do not react with each other before the point of dilution and / or use. In some aspects, the order in which the components are introduced to form solids is non-restrictive because the water introduced into the solid composition is minimal and / or no water is introduced into the solid composition. However, in some aspects, the pressed solid detergent blocks are made by using a bonding system to minimize any damage to the coated particles that can be used. Advantageously, the pressing process for preparing the pressed solid detergent blocks generates pressed solid detergent blocks and prevents the reaction or mixing of components. In one aspect of the present disclosure, the solid detergent composition remains unreacted or unmixed until the point of use, such as dilution.

[0521] In a pressed solid process, a flowable solid, such as a granular solid or other particulate solid containing a binder, is combined under pressure. In a pressed solid process, a flowable solid of the composition is placed into a forming part, such as a mold or a container. The method may include gently pressing the flowable solid in the forming part to produce a solid cleaning composition.

[0522] Enzymatic detergents and cleaning compositions or products can be provided in concentrated form and diluted into a use solution or provided in the form of a use solution. Preferably, the use composition is diluted to a concentration between about 500 ppm and about 5000 ppm, more preferably between about 750 ppm and about 4500 ppm, and most preferably between about 1000 ppm and about 4000 ppm.

[0523] The enzymatic detergents and cleaning compositions or products according to the invention are used for household cleaning, medical cleaning, institutional cleaning (such as cleaning of schools, airports, hospitals) or industrial cleaning.

[0524] Enzymatic detergents and cleaning compositions or products according to the present invention can be prepared by combining and mixing the various ingredients according to conventional and known methods. Preferably, the enzyme is added last to prevent enzyme denaturation or inactivation. Mixing can be carried out by any suitable automatic or manual method. For example, automatic or manual stirring can be performed. The enzymatic detergent composition can be prepared in an intermittent or continuous process.

[0525] Based on the aforementioned advantageous effects thereof, the detergents and cleaning compositions according to the present invention (which contain a combination of enzymes and enzyme stabilizers such as alkanediol, caprylic acid glyceryl, 4-hydroxyacetophenone, ethylhexylglycerol and / or tropolone) are particularly effective for effectively removing stains and / or soils from substrates during washing and cleaning processes.

[0526] Therefore, the present invention relates in a further aspect to a method of treating a stained and / or soiled substrate, the method comprising the steps of: - treating substrates with detergent and cleaning compositions or products according to the invention; and - Rinse the substrate in water to remove the composition or product.

[0527] Preferably, the method of treating a soiled and / or stained substrate is carried out in the wash containing a wash liquor comprising water and an enzymatic detergent and cleaning composition according to the invention. The wash liquor may be applied to the substrate or the substrate may be immersed in the wash liquor.

[0528] The method may alternatively include applying an enzymatic detergent and cleaning composition (i.e., insoluble in the absence of water) directly to part or all of the substrate to treat stains and / or soils directly on the substrate. Such a process is preferably a pre-treatment and may then be treated with or in a wash liquor.

[0529] The method according to the present invention is applicable to both higher and lower temperatures. Dishwashing applications, for example, clean substrates at temperatures exceeding about 60° C., or exceeding about 70° C., or between about 65° C. and 80° C. Laundry applications, for example, clean clothes at temperatures exceeding about 40° C., or exceeding about 50° C., or between about 65° C. and 90° C.

[0530] Preferably, the method is applied at low temperatures, at which stain and / or soil removal is more problematic. Preferably, the treatment temperature is below 50°C, preferably below 40°C, more preferably below 30°C.

[0531] Enzymatic detergents and cleaning compositions according to the present invention are particularly effective in stain and / or soil removal at such low temperatures.

[0532] Thus, the method allows for enzymatic removal of stains and / or soils in a low temperature range, regardless of the temperature sensitivity of the enzyme used.

[0533] This is particularly advantageous when treating sensitive substrates such as wool, silk and synthetic fibers (such as polyester, acrylic, nylon) that can only be washed or cleaned at low temperatures.

[0534] Preferably, the substrate is cotton.

[0535] More preferably, the substrate is wool or silk.

[0536] More preferably, the substrate is a blended fabric, such as cotton and polyester, or a synthetic fiber, such as polyester, acrylic, nylon.

[0537] Based on the advantageous enzyme stabilizing effect, as described above for enzyme stabilizers, the present invention in a further aspect relates to the use of at least one enzyme stabilizer for stabilizing enzymes in detergent and cleaning compositions, the at least one enzyme stabilizer being selected from the group consisting of: (b I ) at least one linear alkanediol having a carbon chain of 5 to 14 carbon atoms or a mixture comprising at least one first linear alkanediol having a carbon chain of 5 to 14 carbon atoms and one or more second linear alkanediols having a carbon chain of 5 to 14 carbon atoms different from the first linear alkanediol, as defined herein; (b II ) Glyceryl caprylate; (b III )4-hydroxyacetophenone; (b IV )Ethylhexylglycerin; (b V )tropolone; and Any mixture thereof.

[0538] Concerning enzyme stabilizers and preferred variants thereof, reference is made to the above description in connection with the detergents and cleaning compositions according to the invention, which, to avoid repetitions, also applies to the use of at least one enzyme stabilizer for stabilizing enzymes in detergents and cleaning compositions.

[0539] Concerning the enzymes and preferred variants thereof, reference is made to the above description of the enzymes in connection with the detergents and cleaning compositions according to the invention, which, to avoid repetitions, also applies to the use of at least one enzyme stabilizer (b) for stabilizing the enzymes in the detergents and cleaning compositions.

[0540] Preferably, the enzyme is selected from the group consisting of proteases, amylases, lipases, cellulases, cutinases, gluconidases, peroxidases, pectinases, mannanases, esterases, hemicellulases, xylanases, phospholipases, pectate lyases, keratinases, reductases, nucleases (including DNases and / or RNases), phenoloxidases, lipoxygenases, ligninases, pullulanases, tannases, pentosanases, melanases, ß-glucanases, arabinosidases, hyaluronidases, chondroitinases, oxidoreductases and any mixtures thereof.

[0541] More preferably, the enzyme is selected from the group consisting of proteases, amylases, lipases, cellulases, mannanases, pectate lyases and any mixtures thereof.

[0542] Surprisingly, it was found that the use of at least one enzyme stabilizer as described herein stabilizes enzymes in detergents and cleaning compositions during storage, resulting in better cleaning performance compared to detergents and cleaning compositions without said enzyme stabilizing material.

[0543] Therefore, the use of the aforementioned substances allows stabilization of enzymes in detergents and cleaning compositions, especially during storage. This excellent effect is based on the excellent enzyme stability produced by the combination of enzyme and enzyme stabilizer.

[0544] Due to the improved enzyme stabilization effect, the amount of enzyme in detergents and cleaning compositions comprising the enzyme can be reduced, and the use of other enzyme stabilizers can be nearly eliminated or at least reduced, while providing stable enzymatic detergents and cleaning compositions.

[0545] Furthermore, surprisingly, at least one enzyme stabilizer as described herein can be used as an enzyme stabilizer (as previously described as an additional enzyme stabilizer) in place of a commercially available enzyme stabilizer: thus, the composition can use less enzyme stabilizer, such as a reduced amount of ingredients including, for example, borates.

[0546] Based on the advantageous enzyme stabilizing effect, as described above for the enzyme stabilizer, the present invention finally relates to a method for stabilizing enzymes in detergent and cleaning compositions, the method comprising the following steps: i. Providing detergents and cleaning compositions comprising enzymes; and ii. adding thereto an effective amount of at least one enzyme stabilizer selected from the group consisting of: (b I ) at least one linear alkanediol having a carbon chain of 5 to 14 carbon atoms or a mixture comprising at least one first linear alkanediol having a carbon chain of 5 to 14 carbon atoms and one or more second linear alkanediols having a carbon chain of 5 to 14 carbon atoms different from the first linear alkanediol, as defined herein; (b II ) Glyceryl caprylate; (b III )4-hydroxyacetophenone; (b IV )Ethylhexylglycerin; (b V )tropolone; and Any mixture thereof.

[0547] Concerning enzyme stabilizers and preferred variants thereof, reference is made to the above description in connection with the detergents and cleaning compositions according to the invention, which, to avoid repetitions, also applies to the use of at least one enzyme stabilizer for stabilizing enzymes in detergents and cleaning compositions.

[0548] Concerning the enzymes and preferred variants thereof, reference is made to the above description of the enzymes in connection with the detergents and cleaning compositions according to the invention, which, to avoid repetitions, also applies to the method for stabilizing the enzymes in detergents and cleaning compositions.

[0549] Preferably, the enzyme is selected from the group consisting of proteases, amylases, lipases, cellulases, cutinases, gluconidases, peroxidases, pectinases, mannanases, esterases, hemicellulases, xylanases, phospholipases, pectate lyases, keratinases, reductases, nucleases (including DNases and / or RNases), phenoloxidases, lipoxygenases, ligninases, pullulanases, tannases, pentosanases, melanases, ß-glucanases, arabinosidases, hyaluronidases, chondroitinases, oxidoreductases and any mixtures thereof.

[0550] More preferably, the enzyme is selected from the group consisting of proteases, amylases, lipases, cellulases, mannanases, pectate lyases and any mixtures thereof.

[0551] During storage of detergents and cleaning compositions, the enzymes contained therein are destroyed, for example by inactivation, denaturation or disintegration, for example by physical influences such as temperatures above 35° C., oxidation or proteolytic cleavage. Subsequently, the detergents and cleaning compositions lose their enzymatic properties.

[0552] Surprisingly, it has been found that adding an effective amount of at least one enzyme stabilizer as defined herein to enzyme-containing detergents and cleaning compositions has a positive impact, as they significantly slow down the rate of enzyme inactivation by effectively stabilizing the enzyme. The enzymes in these detergents and cleaning compositions show excellent stability during storage, thus maintaining performance over time. More specifically, the enzymatic detergents and cleaning compositions exhibit stability after storage for at least 2 weeks and at temperatures above standard ambient temperature (25°C), in particular above 35°C.

[0553] Therefore, adding one of the aforementioned enzyme stabilizing materials to detergents and cleaning compositions is beneficial in a method for stabilizing the enzyme contained therein during storage. The combination of the enzyme stabilizer of the present invention and the enzyme helps to stabilize the enzyme more effectively during storage and leads to improved cleaning performance of the detergents and cleaning compositions compared to detergents and cleaning compositions that do not contain the enzyme stabilizer.

[0554] Additionally, based on the improved enzyme stability, especially during storage, the enzymes can work longer and thus provide more cleaning benefits by effectively removing stains and / or soils.

[0555] Conversely, also due to the excellent stability of the enzymes, the amount of enzymes or additional enzyme stabilizers and other ingredients used to increase the stability of the enzymes in these detergent and cleaning compositions can be reduced without losing cleaning performance.

[0556] In a final aspect, the invention relates to an enzyme composition, The enzyme composition comprises or consists of: (A) at least one enzyme; (B) at least one enzyme stabilizer selected from the group consisting of: (B I ) a mixture comprising at least one first linear alkanediol having a carbon chain of 5 to 14 carbon atoms and one or more second linear alkanediols having a carbon chain of 5 to 14 carbon atoms different from the first linear alkanediol; (B II ) Glyceryl caprylate; (B III )4-hydroxyacetophenone; (B IV )Ethylhexylglycerin; (B V )tropolone; and Any mixture thereof; and (C) at least one additional enzyme stabilizer different from the enzyme stabilizer (B).

[0563] It was found that the above combination of enzyme (A) and enzyme stabilizer (B) results in excellent enzyme stability in the enzyme composition / formulation, especially during storage.

[0564] With regard to the further enzyme stabilizers (C) and preferred variants thereof, reference is made to the above description of the further enzyme stabilizers in connection with the detergent and cleaning compositions according to the invention, which, to avoid repetitions, also applies to the enzyme compositions.

[0566] The present invention will now be described in detail with reference to the following examples, which are intended only to illustrate the present invention, so that the content of the present invention is not limited to or confined to the following examples.

[0567] Example Example 1 : The following tests were conducted to show the stabilizing influence of different enzyme stabilizers according to the invention on the stability of different enzymes and thus the cleaning performance of detergents and cleaning compositions according to the invention.

[0568] Detergents and cleaning compositions are laundry detergents, hand dishwashing detergents and automatic machine dishwashing detergents.

[0569] For this purpose, samples of detergent and cleaning compositions comprising an enzyme or an enzyme mixture according to the invention and an enzyme stabilizer were stored for 2 weeks, 4 weeks, 6 weeks and 12 weeks.

[0570] The enzymes in the detergent and cleaning compositions are selected from proteases, amylases, lipases or cellulases according to different sensitivities (protease sensitivity, amylase sensitivity, etc.).

[0571] Storage of each sample was also performed at different storage temperatures, namely 4°C, 20°C and 35°C.

[0572] In parallel, the same comparative tests are carried out under the same conditions on detergent and cleaning compositions containing the same enzyme or enzyme mixture but without enzyme stabilizer.

[0573] The cleaning performance of the tested detergents and cleaning compositions according to the invention and comparative detergent cleaning compositions were tested before storage and after 2, 4, 6 and 12 weeks of storage as described below.

[0574] Example 1.1: Laundry detergent The cleaning performance of laundry detergents is analyzed according to the standard AISE (International Association of Soaps, Detergents and Maintenance Products) laundry detergent testing guidelines.

[0575] The cleaning performance test involves evaluating the stain removal efficiency of the tested laundry detergents on 14 stains.

[0576] Test conditions: Washing machine, Miele European household front-loading washing machine Water hardness: 2.5mmol / l Water temperature: 40℃ Washing cycles: 6 cycles (heavy duty detergent: cotton cycle; Light Detergent: Delicate cycle) Ballast load: 3kg, clean white ballast load Ballast dirt: 4 pieces of SBL 2004 (100% cotton, about 8g dirt / cloth sample) Dosage: Recommended dose for normal dirt / medium hardness Drying: Dry overnight Stain Collection: Tea, Chocolate, Coffee, Grass, Red Wine, Grass / Mud, Juice, Blood, Tomato Puree, Unused Motor Oil, Salad Dressing Balsamic Vinegar, Cooked Beef Fat, French Squeezed Mustard, and Makeup.

[0577] Each stain was measured / rated before washing (to verify the quality of the stain) and after washing.

[0578] The degree of stain removal can be evaluated by: (B) Sensory panel (rating 1 to 10: Rating 1: No cleaning; Rating 10: Complete removal) (C) Spectrophotometer, or digital image analysis system, used to determine the stain removal index (SRI) whiteness W Results were statistically analyzed using Tukey's HSD test (HSD = Honestly Significant Difference) with a 95% confidence level. The HSD value highlights significant differences between each pair of products.

[0579] Example 1.2: Hand dishwashing detergent The cleaning performance of hand dishwashing detergents was analyzed according to the quality assessment recommendations for the cleaning performance of IKW hand dishwashing detergents.

[0580] The test consists in measuring the efficiency of a hand dishwashing detergent by the stability of its foam while cleaning dishes coated with a representative mixed soil containing liquids, proteins and carbohydrates (foam mileage test: duration of foam).

[0581] Test conditions: Water hardness: 16 ± 2°d Water temperature: 45℃±1℃ Test soils: (1) Low-fat soils: Composition as specified in the IKW recommendations; and (2) Normal dirt: Composition as specified in the IKW recommendations The soil is applied to the center of the dish by an automatic dispenser.

[0582] Dishwashing process: As specified in the IKW recommendations End point identification: When the foam layer breaks permanently on the surface of the dishwashing soak, the dishwashing soak is considered exhausted and the endpoint has been reached. The number of wash dishes tested for each wash is recorded in the test protocol.

[0583] For each type of soil, five wash tests were performed with each test product.

[0584] The products were compared based on the number of discs washed out until the foam burst. Tukey's HSD statistical test was performed at a 95% confidence level.

[0585] Example 1.3: Machine dishwashing detergent Analyze the cleaning performance of machine dishwashing detergents according to the quality assessment recommendations of the cleaning performance of IKW dishwasher detergents.

[0586] The cleaning performance test involves evaluating the stain removal efficiency of the tested laundry detergents on 14 stains.

[0587] Test conditions: Washing machine, Miele dishwasher GSL or Miele GSL 2 Water hardness: For typical products: 1.8mmol / l For multifunctional products: 3.5mmol / l Water temperature: During main wash cycle: 45°C Washing cycles: at least 3 cycles Dosage: Recommended dose for normal dirt / medium hardness Stain collection: black tea (bleachable), Milk, milk skin (long-lasting / sensitive to alkali), Starch mixtures, pasta (contains starch, amylase-sensitive), Egg yolk, cream pudding, minced meat (contains egg white, sensitive to proteases) Number of dirty items: 6 of each type Each stain was measured / evaluated either by visual evaluation with reference to a photo catalogue or by gravimetric analysis as described in the IKW recommendations.

[0588] The results obtained were statistically analyzed using Tukey's HSD test (HSD = Honestly Significant Difference) with a 95% confidence level. The HSD value highlights the significant differences between each pair of products.

[0589] As can be seen from the above tests, the detergent and cleaning composition according to the present invention showed excellent cleaning performance even after storage for 12 weeks, compared with the cleaning performance without the enzyme stabilizer of the present invention. On the contrary, this means that the enzyme in the detergent and cleaning composition is stabilized by adding the enzyme stabilizer of the present invention during storage, while in the detergent and cleaning composition without adding the enzyme stabilizer, the enzyme performance decreases over time.

[0590] Example 2: Evaluation of enzyme stability of enzyme detergents and laundry detergent compositions according to the present invention in terms of stain removal performance Qualitative The following test was conducted to show the stabilizing effect of different enzyme stabilizers on the stability of different enzymes in detergent and cleaning compositions in terms of stain removal performance before and after storage at 40°C for 1 month.

[0591] To evaluate laundry stain removal performance, laundry detergent compositions were tested in combination with different enzyme stabilizers. The laundry detergent compositions were blended with different enzyme stabilizers as specified in the table below and evaluated according to the spectrocolorimeter measurements described below and compared to a laundry detergent composition without added enzyme stabilizer (placebo).

[0592] The stain removal efficacy was tested according to the following test protocol: Principle: This test involves evaluating the efficiency of the tested detergents in removing 12 stains. Fabric stains are artificially applied to a specified fabric type and allowed to set for a specified amount of time. The size of each stain sample allows for repeatable readings (50mm diameter). These stained swatches are washed / soaked with the test detergent being compared and the relative extent of stain removal is evaluated. This test allows the comparison of the stain removal abilities of products under identical conditions.

[0593] Stain Selection: To test the effectiveness of the detergents tested, a ready-to-use normalized multi-sample and multi-point monitor (selected and manufactured by Warwick Equest and CFT) was used.

[0594] Description of the stain: ●CS-44 Chocolate Drink, Pure, on Cotton ●CS-07 grass, pure, on cotton ●PC-05 Blood, milk, ink (BMI) on polyester / cotton ●WE5DASB double applied sheep blood on knitted cotton ●CS-68 Chocolate Ice Cream, Aged, on Cotton ●E-165 Chocolate Pudding, on cotton cloth ●E-161 starch, on cotton ●CS-27 Potato Starch, Colored, on Cotton ●CS-62 lard, colored with Sudan red, on cotton ●C-H126 vegetable oil, colored with purple dye, on cotton ●C-H141 Sugar-free pectin, on cotton cloth ●C-H147 Jam, forest fruit, on cotton cloth The stains are manufactured in a reproducible manner and with consistent quality. The stains are a mixture of "natural stains" and "normalized stains". The stains are evenly distributed and colored before and after washing. Therefore, 12 different stain formulations can be tested simultaneously in one testing process. Some stains are particularly sensitive to the enzymes specified in the table below.

[0595]

[0596] Test conditions: Each test sample group of 12 stains was soaked in a washpot containing 833.3 g of the tested laundry detergent solution at a temperature of 40° C. for 30 minutes.

[0597] 833.3 g of laundry detergent solution consisted of the following dilution: 3 g of liquid laundry with a hardness of 15° Hf.

[0598] The test solutions were agitated using a Rotawash M228B / C.

[0599] At the end of the test cycle, remove the stain from the washtub and lay it horizontally to dry.

[0600] Measurements / Evaluations: Average reflectance measurements of fabrics were made using a spectrocolorimeter Ci62 before the tissue was stained, after it was stained, and again after treatment with the tested laundry detergent and washing. Three measurements were made for each stain. The performance of the products was evaluated instrumentally based on the Stain Removal Index (SRI). The SRI is a scale of 0 to 100, with 0 representing no stain removal and 100 representing complete stain removal.

[0601] As described in ASTM D4265, the SRI is calculated according to the following formula:

[0602] in: US = Unwashed stain area UF = Unwashed (unstained) fabric area ΔE * (US - UF) = Delta-E color difference between unwashed stain and unwashed fabric ΔE*(WS - UF) = Delta-E color difference between washed stain and unwashed fabric.

[0603] The value ΔE (absolute color difference) is calculated as:

[0604] in: L = reflectivity a = redness / greenness b = yellowness / blueness The tested laundry detergent compositions were compared to each other as follows: the higher the SRI, the better the laundry cleaning performance, ie the better the stain removal performance.

[0605] To test the stabilizing efficacy of different enzyme stabilizers, an enzyme-containing laundry detergent formulation with the following composition was used:

[0606] *)Medley pure 300L is a blend of proteases, amylases, pectate lyases, mannanases and lipases.

[0607] To the laundry detergent formulations were added different enzyme stabilizers according to the present invention and the stain removal performance was evaluated according to the above test methods and the methods specified in the table below.

[0608] The stain removal performance of each test sample was measured before storage (t=0) and after 1 month of storage (t=1 month).The test samples were stored in an oven (darkness) at a temperature of 40°C.

[0609] Evaluation of enzyme stabilization effect: The lower the ΔSRI between SRI (t=0) and SRI (t=1 month), the better the enzyme stabilization effect of the tested enzyme stabilizer.

[0610] In the following table, the following abbreviations are used: C5 = 1,2-pentanediol C6 = 1,2-Hexanediol C7 = 1,2-Heptanediol C8 = 1,2-octanediol C10 = 1,2-decanediol 4HAP = 4-Hydroxyacetophenone 2.1 Stain removal performance of different 1,2-alkanediols on amylase-sensitive stains Table 1 :

[0611] As can be seen in Table 1, the addition of 1,2-alkanediol to detergents and laundry compositions results in improved enzyme stability on amylase sensitive stains compared to detergents and laundry compositions without enzyme stabilizers. Surprisingly, the addition of 1,2-hexanediol, 1,2-heptanediol and 1,2-decanediol results in a better stabilizing effect compared to 1,2-pentanediol. Thus, by adding 1,2-hexanediol, 1,2-heptanediol or 1,2-decanediol to detergent or laundry formulations, the stability of enzyme-containing detergents and cleaning compositions can be significantly improved. In terms of stain removal efficacy, 1,2-hexanediol shows the best enzyme stabilizing effect on amylase sensitive stains.

[0612] 2.2 Stain removal performance of different 1,2-alkanediols on lipase-sensitive stains Table 2 :

[0613] As can be seen in Table 2, the addition of 1,2-alkanediol to detergents and laundry detergent compositions results in improved enzyme stability on protease sensitive stains compared to detergents and laundry detergent compositions without enzyme stabilizers. Surprisingly, the addition of 1,2-hexanediol, 1,2-heptanediol and 1,2-octanediol results in a better stabilizing effect compared to 1,2-pentanediol. Thus, by adding 1,2-hexanediol, 1,2-heptanediol or 1,2-octanediol to detergent or laundry detergent formulations, the stability of enzyme-containing detergents and cleaning compositions can be significantly improved.

[0614] 2.3 Stain removal performance of a mixture of 4-HAP and 1,2-alkanediol on lipase-sensitive stains Table 3 :

[0615] As can be seen in Table 3, the addition of 4-hydroxyacetophenone alone or a mixture of 4-hydroxyacetophenone and 1,2-alkanediol to detergents and cleaning compositions produces an enzyme stabilizing effect compared to the addition of any enzyme stabilizing effect to the detergents and cleaning compositions.

[0616] 2.4 Stain removal performance of 1,2-alkanediol or mixture of 1,2-alkanediol on protease-sensitive stains Table 4 :

[0617] As can be seen in Table 4, the addition of 1,2-alkanediol to detergents and laundry washing compositions results in improved enzyme stability on protease sensitive stains compared to detergents and laundry washing compositions without enzyme stabilizers. Surprisingly, the addition of 1,2-heptanediol or 1,2-decanediol results in a better stabilizing effect compared to 1,2-pentanediol. Thus, by adding 1,2-heptanediol or 1,2-decanediol to detergent or laundry washing formulations, the stability of enzyme-containing detergents and cleaning compositions can be significantly improved.

[0618] Surprisingly, a mixture of two different 1,2-alkanediols, such as a mixture of 1,2-pentanediol and 1,2-heptanediol or a mixture of 1,2-decanediol and 1,2-heptanediol, has a synergistic enzyme stabilizing effect compared to the use of a single 1,2-alkanediol.

[0619] 2.5 Stain removal performance of a mixture of 4-HAP and 1,2-alkanediol on protease-sensitive stains Table 5 :

[0620] As can be seen from Table 5, the addition of 4-hydroxyacetophenone alone or a mixture of 4-hydroxyacetophenone and 1,2-alkanediol to the detergent and cleaning composition produces an enzyme stabilizing effect compared to the detergent and cleaning composition to which any enzyme stabilizer is added. The enzyme stabilizing effect of the mixture of 4-hydroxyacetophenone and 1,2-alkanediol is even better, i.e., synergistic, than the enzyme stabilizing effect of using a single substance.

[0621] As can be seen from the above results, the addition of the enzyme stabilizer specified in the present application to the enzyme detergent and cleaning composition alone or in the form of a mixture of two promoters leads to a significant improvement in enzyme stability. Even at a low addition rate of the enzyme stabilizer or its mixture, the detergent and cleaning composition show excellent enzyme stability after storage. Due to the small degree of enzyme inactivation after storage, the detergent and cleaning composition according to the present invention has a low degree of degradation in cleaning performance compared to the detergent and cleaning composition to which such enzyme stabilizer is not added, or even no degradation.

[0622] Example 3: Analysis of enzyme stability The effects of different enzyme stabilizers and their concentrations on enzyme stability were evaluated by enzyme assay.

[0623] An enzyme assay is a normalized experimental protocol established to measure the activity or concentration of an enzyme in a biochemical system. Most enzymatic assays are based on the detection of a fluorescent, luminescent, or spectrophotometric endpoint signal.

[0624] The enzyme stabilizers according to the invention and the enzymes as described herein were tested in a suitable expander.

[0625] Three different enzymes were tested, namely protease, amylase and lipase.

[0626] The enzyme composition was prepared by varying the concentration of the enzyme stabilizer. The amount of enzyme in the buffer system was kept constant.

[0627] The samples were analyzed for enzyme stability by a suitable enzyme assay. The stability results were collected for each enzyme tested.

[0628] The formulation samples were then stored at different storage temperatures (ie 4°C, 20°C and 35°C) for periods of 2 weeks, 4 weeks, 6 weeks and 12 weeks. Samples of each formulation tested were then collected and analyzed by enzyme assay.

[0629] From the results it can be seen that even after 12 weeks of storage, the tested enzymes retained enzyme performance. These results show that the enzyme stabilizer of the present invention provides retention of enzyme performance.
