Background Art

[0003] Detergents and / or cleaning compositions must remove multiple stains and dirt from different substrate types under a wide range of cleaning conditions. Detergents and cleaning compositions (particularly detergents and cleaning compositions for clothing and textile cleaning, dishwashing, etc.) are mainly composed of a mixture of surfactants or surfactants, and their main task is to remove water-insoluble substances, such as dirt and grease, from surfaces such as fabrics, clothes, dishes, utensils, etc. and hard surfaces such as metals, plastics, glass, ceramics, etc. In addition to the surfactant, modern detergents and / or cleaning formulations are composed of builders, chelating agents, co-builders and other polymer additives for specific washing or cleaning effects (such as decontamination and anti-redeposition), dye transfer inhibition and rheology modification. In addition to the ingredients, one or more bleaching agents are usually added to the detergent and cleaning compositions as additional active substances.

[0004] At present, for example, many consumer products such as detergents, fabric softeners, washing powders, liquid detergents, shower gels, shampoos, deodorants, lotions, etc. are perfumed with fragrance materials or contain cosmetic ingredients to deliver specific effects. Detergents and / or cleaning compositions should especially provide fresh fragrance, so that not only visually but also olfactorily perceive the freshness and cleanliness after cleaning or washing. Preferably, detergents and / or cleaning compositions should also provide effective malodor coverage / masking or removal, i.e. remove or reduce undesirable and quite unpleasant odors on corresponding cleaning articles. Clean articles should smell fresh and clean, without the malodor adhering to the articles, or alternatively give a certain desired fragrance or fresh feeling. This clean or fresh feeling is particularly desirable for, for example, laundry detergents, toilet bowl cleaners, etc.

[0005] In order to achieve the desired odor impression, a variety of ingredients, such as additives and auxiliaries, are usually required, or a large amount of fragrance components must be added. Common additives for improving the fragrance impression are so-called fixatives, i.e. fragrance blockers. These substances are usually substances with low volatility. Unfortunately, however, these substances and their fragrance can interfere with other ingredients of detergents and / or cleaning formulations, thereby changing the desired odor impression of the fragrance components, or these substances can also hinder each other in terms of fragrance formation.

[0006] Furthermore, household care products such as laundry detergents (in powder or liquid form), fabric conditioners, dishwashing detergents, floor and surface cleaners, glass cleaners, air fresheners, etc. should be able to effectively reduce malodors or unpleasant odors, such as human or animal sweat on household furniture and textiles (such as pillows, sofa coverings, etc.), clothing, carpets, etc. In addition, effective detergents and / or cleaning compositions should prevent the formation of malodors.

[0007] Malodors are present in many environments. Such odors are generated in industrial, commercial, and residential environments. In industrial environments, odors are often generated by processes involving the use of chemicals. In commercial and residential environments, malodors can be generated, for example, by waste products, garbage containers, cat litter, sweat, and food handling and processing.

[0008] Unfortunately, the various ingredients of these detergents and / or cleaning compositions may interact with each other during use or may cause allergic reactions. In addition, the more volatile components of the fragrance formulations of such compositions tend to evaporate prematurely. This therefore leads to an undesirable change and / or reduction in the fragrance impression.

[0009] Therefore, the detergent industry has been searching for ingredients that can address these negative issues.

[0010] Therefore, there remains a continuing need for materials that can improve the cleaning and fragrance performance of detergent and / or cleaning compositions containing fragrance components without the need for multiple additional additives.

[0011] Furthermore, there is a need for less complex, highly effective detergent and / or cleaning compositions which avoid the use of ingredients that are undesirable in environmental and health terms.

[0012] Therefore, an object of the present invention is to provide a multiple-use detergent and / or cleaning composition with excellent fragrance properties and improved cleaning performance. In particular, an object of the present invention is to provide a detergent and / or cleaning composition with improved fragrance properties in terms of strength and adhesion.

[0013] Furthermore, it was an object of the present invention to provide detergents and / or cleaning compositions which provide better cleaning performance and an improved malodor reduction and / or covering effect and additionally prevent the formation of malodors compared to detergents and / or cleaning compositions comprising customary formulations.

[0014] Furthermore, it is an object of the present invention to provide a method for cleaning substrates which has improved olfactory properties in terms of strength and adhesion without the need for additives such as fixing agents.

[0015] Another object of the present invention is to provide substances or substance mixtures which are able to enhance the fragrance intensity of odorous substances in detergents and / or cleaning compositions and to improve the adhesion of odorous substances contained in detergents and / or cleaning compositions even when small amounts of fragrance components are used.

[0016] Finally, it is an object of the present invention to provide a method for enhancing or improving the cleaning efficiency of a detergent and / or cleaning composition and / or improving malodor coverage and / or malodor reduction and / or malodor prevention.

[0017] Surprisingly, it has been found that the addition of an effective amount of 1,2-heptanediol or 2,3-heptanediol or a mixture comprising 1,2-heptanediol and 2,3-heptanediol or a specific mixture of at least one further alkanediol as specified herein with at least one further enhancer, such as glyceryl caprylate, 4-hydroxyacetophenone and / or ethylhexylglycerol, as a fragrance enhancer (as defined herein) to a detergent and / or cleaning composition comprising an odoriferous component has a positive influence on the cleaning performance and effectively allows an improved fragrance impression. Substrates treated with the detergent and / or cleaning composition according to the invention show a significantly increased fragrance impression and prolonged adhesion compared to formulations not comprising 1,2-heptanediol or 2,3-heptanediol or a mixture comprising 1,2-heptanediol and 2,3-heptanediol or a mixture of at least one further alkanediol as specified herein with glyceryl caprylate, 4-hydroxyacetophenone and / or ethylhexylglycerol as a fragrance enhancer. Surprisingly, mixtures of alkylene glycols with caprylic acid glyceryl, 4-hydroxyacetophenone and / or ethylhexylglycerol show excellent fragrance enhancing properties, i.e., the intensity and adhesion of the fragrance contained in the detergent and / or cleaning composition are improved even when using small amounts of fragrance components without the need for the addition of fixatives and the like, thereby reducing the total amount of ingredients in the final formulation and reducing the allergenic potential and environmental impact of the final product formulation.

[0018] Therefore, no additional additives are required to achieve adequate adhesion.

[0019] In addition, it is surprising to find that the compositions disclosed herein can effectively reduce malodor or at least effectively cover malodor. In addition, it is surprising to find that the compositions disclosed herein can effectively prevent the formation of malodor. These effects are not only based on the presence of odor components, but are produced by the synergistic interaction of the individual components of the composition.

[0020] Furthermore, the fragrance enhancing components simultaneously improve cleaning performance such that fewer ingredients overall are required to provide an effective detergent and / or cleaning formulation providing a clean and fresh result and impression.

[0021] More specifically, it has surprisingly been found that the addition of an effective amount of 1,2-heptanediol or 2,3-heptanediol or a mixture comprising 1,2-heptanediol and 2,3-heptanediol or at least one 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 and glyceryl caprylate, 4-hydroxyacetophenone and / or ethylhexylglycerol as defined herein to a detergent and / or cleaning composition improves the fragrance intensity of the fragrance in the detergent and / or cleaning composition comprising odoriferous components and prolongs their adhesion on the treated substrates, thereby ensuring a prolonged fragrance, compared to detergents and / or cleaning compositions not containing such fragrance enhancing compositions based on a combination of specific hydroxyl compounds as defined herein.

[0022] Thus, perfumed detergent and / or cleaning compositions containing a fragrance component and 1,2-heptanediol or 2,3-heptanediol or a mixture comprising 1,2-heptanediol and 2,3-heptanediol or at least one 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 and glyceryl caprylate, 4-hydroxyacetophenone and / or ethylhexylglycerol as defined herein provide improved overall performance in terms of cleaning and fragrance impression over detergents and / or cleaning compositions not containing such fragrance enhancing compositions.

[0023] Conversely, also due to the enhanced effects in fragrance performance, cleaning performance and malodor reduction / prevention performance, the amount of additives (such as fixatives), fragrances, malodor reducers and other ingredients used to increase the efficacy and fragrance performance in these detergents and / or cleaning compositions can be reduced without sacrificing cleaning performance. Summary of the invention

[0024] The present invention is made in view of the above disadvantages.

For these alkanediols, particularly pronounced enhancement effects are observed, especially in terms of flavor enhancement.

[0034] In a final aspect, the present invention provides a method for enhancing or improving the cleaning efficiency of a detergent and / or cleaning composition and / or for enhancing the olfactory properties of odorous substances and / or for enhancing the adhesion of odorous substances and / or for malodor reduction and / or for malodor prevention, comprising the following steps: (i) providing a detergent and / or cleaning composition comprising at least one surfactant and at least one odoriferous substance; and (ii) adding thereto an effective amount of 1,2-heptanediol or a mixture of 2,3-heptanediol or a mixture comprising 1,2-heptanediol and 2,3-heptanediol or a mixture (c), wherein the mixture (c) comprises or consists of: (c I ) at least one reinforcing agent selected from the group consisting of: at least one linear alkane diol having a carbon chain of 5 to 14 carbon atoms, or a mixture comprising at least one first linear alkane diol having a carbon chain of 5 to 14 carbon atoms and one or more second linear alkane diols having a carbon chain of 5 to 14 carbon atoms different from the first linear alkane diol; and at least one other enhancer selected from the group consisting of: (c II ) Glyceryl caprylate; (c III )4-hydroxyacetophenone; (c IV )ethylhexylglycerin; and Any mixture of these other enhancers.

[0037] The present invention is specifically described in the appended claims. However, the present invention itself and its preferred variations, other objects and advantages are also apparent from the following detailed description in conjunction with the appended embodiments and drawings.

[0038] Unless otherwise indicated, all percentages are by weight.

[0039] Numerical ranges recited in the specification and given in the format of "x to y" include the values ​​defining the range and include each integer within the defined range. When multiple preferred numerical ranges are specified in this format, all ranges generated by combining the various endpoints are also included.

[0040] In the context of the present invention, the term "comprising" means that the mentioned components are essential, but other components may be added and still be encompassed by the present invention.

[0041] The term "consisting of" as used according to the present invention means that the total amount of components (a) to (c) (and respectively (a) to (d)) adds up to 100 wt.-%, based on the total weight of the detergent and / or cleaning composition, and indicates that the subject matter is closed and may include only the limitations explicitly stated.

[0042] Unless the context indicates otherwise, whenever "comprising" is mentioned, it is intended to encompass both meanings as alternatives, ie, the meaning may be "including" or "consisting of."

[0043] In the context of the present invention, the term "at least one ..." or "one or more ..." means that the detergent and / or cleaning composition according to the present invention may contain any one or a mixture of two, three, four, five, six or even more different corresponding components following the term.

[0044] The term "and / or" indicates that there is a connection, or that an alternative is provided.

[0045] The term "optionally" means that the subsequently described component may but need not be present in the detergent and / or cleaning composition, and that the description includes variations in which the compound is included and variations in which the compound is not present.

[0046] As used herein, the term "alkyl" refers to a saturated hydrocarbon having one or more carbon atoms, including straight-chain alkyl groups (such as methyl, ethyl, propyl, butyl, pentyl, hexyl, heptyl, octyl, nonyl, decyl, undecyl, dodecyl, tridecyl, tetradecyl, pentadecyl, hexadecyl, heptadecyl, octadecyl, etc.), cyclic alkyl groups (or cycloalkyl or alicyclic or carbocyclic groups) (such as cyclopropyl, cyclopentyl, cyclohexyl, cycloheptyl, cyclooctyl, etc.), branched alkyl groups (such as isopropyl, tert-butyl, sec-butyl, isobutyl, etc.) and alkyl-substituted alkyl groups (such as cycloalkyl-substituted alkyl groups).

[0047] Unless otherwise indicated, the term "alkyl" includes unsubstituted alkyl and substituted alkyl. As used herein, the term "substituted alkyl" refers to an alkyl group having a substituent of one or more hydrogens on one or more carbons of a substituted hydrocarbon backbone. Such substituents may include, for example, alkenyl, alkynyl, halogen, hydroxyl, alkylcarbonyloxy, arylcarbonyloxy, alkoxycarbonyloxy, aryloxy, aryloxycarbonyloxy, carboxylate, alkylcarbonyl, arylcarbonyl, alkoxycarbonyl, aminocarbonyl, alkylaminocarbonyl, dialkylaminocarbonyl, alkylthiocarbonyl, alkoxy, phosphate, phosphonate, cyano, amino, imino, sulfydryl, alkylthio, arylthiol, thiocarboxylate, sulfate, alkylsulfinyl, sulfonate, nitro, etc.

[0048] In the context of the present invention, the term "enhance" means "improve", "strengthen", "increase". Accordingly, an "enhancer" or "enhancing composition" is an agent or a mixture of substances (composition) that is able to "improve", "enhance", "increase" certain characteristics or properties as defined herein, in particular the fragrance performance in terms of fragrance intensity and / or fragrance adhesion of odorous substances in detergents and / or cleaning compositions. In addition, the enhancers as specified herein improve the cleaning properties and malodor covering / reducing / preventing properties of the detergents and / or cleaning compositions disclosed herein. Therefore, the term "enhance" is not limited to the fragrance enhancing properties of the corresponding composition.

[0049] The term "adhesion" refers to the residue (also called fixation or tenacity) of a fragrance compound (odorant) on the substrate to which it is applied. The slower the fragrance / aroma of a perfume dissipates, the greater its stickiness, since the adhesion of a fragrance depends on the degree of its volatility. Adhesion is usually achieved by fixation. The terms "fragrance substance", "fragrance compound", "odorant" and "odorant compound" are used synonymously.

[0050] Surprisingly, the compositions according to the invention are effective detergent and / or cleaning compositions while showing improved hold / toughness allowing for a long-lasting and intense fragrance impression.

[0051] The resulting perfumed formulations / products exhibit high strength even at low addition rates of the odoriferous compound while ensuring enhanced anchorage (toughness).

[0052] Many attempts have been made to hide malodors by using deodorizing compositions. Odor neutralizers act to interact with malodors and chemically neutralize them. However, these neutralizers (such as oxidizing agents, such as oxygen bleach, chlorine; chlorinated materials, such as sodium hypochlorite, chlorine dioxide; potassium permanganate; reducing agents, such as sodium bisulfite) are often flammable, explosive, corrosive or toxic. Odor masking agents act to intentionally mask odors by adding another substance. Odor masking has been achieved by using fragrances, perfumes, colognes, etc. In addition, both deodorizers and neutralizers may cause allergic reactions or interact with other components of the final product.

[0053] Typically, masking agents suppress malodors by: (i) using large amounts of fragrances to provide a more pleasant aroma; or (ii) providing fragrances that are blended with the malodor to provide a different and more desirable aroma. Unfortunately, in both cases, large amounts of fragrances must be utilized, which themselves often prove unpleasant. Furthermore, malodors are often still detectable at reasonably tolerable masking fragrance levels. Additionally, high levels of odorous components are expensive and may cause allergic reactions.

[0054] Surprisingly it has been found that the compositions disclosed herein are effective in masking malodors ("malodor coverage"). To achieve effective coverage, only low levels of odoriferous components are required, based on the potentiating effect of the (fragrance) potentiators as specified herein.

[0055] In addition, the compositions disclosed herein are found to be effective in reducing malodors or even preventing the formation of malodors without the need for the addition of harmful or hazardous neutralizers. Thus, the compositions according to the present invention are not only capable of covering or masking malodors, but are also effective in preventing the formation of malodors. DETAILED DESCRIPTION

[0063] As considered herein, the term "detergent and / or cleaning composition" is understood to refer to all products suitable for and commonly used in washing or cleaning. Detergent and / or cleaning composition are mainly composed of surfactants or surfactant mixtures. In addition to surfactants, detergents and / or cleaning compositions are usually composed of builders and chelating agents, co-builders and other polymer additives for specific effects (such as anti-redeposition, dye transfer inhibition or rheology modification). Detergent and / or cleaning composition refers to a composition that can be used to remove undesirable compounds from articles to be cleaned (such as textiles (such as fabrics, clothes), dishes, floors, hard surfaces (such as metals, plastics and ceramics)). These deposits may be caused by stains and dirt, bacteria and other pollutants. Detergent is the cleaning composition most commonly used for textiles. Detergent and / or cleaning composition can be used for household cleaning, public institution cleaning and industrial cleaning. Detergent and / or cleaning composition also includes a disinfectant that kills all vegetative cells (including identified pathogenic microorganisms). Detergent and / or cleaning composition can be used by detergent composition itself or by detergent product or by its use solution.

[0064] The detergent and / or cleaning compositions according to the invention are preferably used for removing stains and / or soils from textiles, fabrics, laundry, dishes, utensils, medical and dental instruments, hard surfaces, etc., while enhancing or improving the olfactory impression and / or for enhancing the adhesion of odorous substances and / or malodor reduction / masking / prevention.

[0065] The detergent and / or cleaning composition according to the invention provides improved cleaning performance and improved olfactory properties as well as malodor reduction and / or malodor masking and / or malodor prevention.

[0066] 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 items / substrates to be cleaned (such as textiles and surfaces), tableware / dishes and other cooking utensils (such as cutlery / silverware, pots, pans, bakeware, etc.) and other substrates.

[0067] These deposits may be formed by stains caused by sweat, grease, tea, chocolate, coffee, grass, red wine, grass / mud, fruit juice, blood, tomato puree, unused motor oil, salad dressing, cooked beef fat, French squeezy mustard, make-up, etc., or by dirt caused by grease, starch-based dirt (such as rice), pasta, protein-based dirt (such as egg yolk), mayonnaise, lipstick, starch-based dirt, etc. and other dirt remaining on the corresponding surface. Deposits are therefore any form of undesirable residues of pollutants, dust, food, grease, etc.

[0068] In the context of the present invention, the term "substrate" includes fabrics, textiles, clothing, dishes, utensils, carpets, any hard surface (such as tiles, floors or furniture), medical and dental instruments, etc., which can be contaminated with stains and / or soil and can be treated by washing or cleaning methods.

[0069] As used herein, the term "dishware" or "ware" refers to any form of kitchenware, diningware, or tableware, such as, but not limited to, pots, cutlery, pans, plates, tongs, knives, forks, spoons, glassware (such as glasses), cutting boards, china, etc.

[0070] The term "hard surface" refers to solid, substantially non-flexible surfaces such as countertops, tiles, floors, walls, panels, windows, plumbing fixtures, kitchen and bathroom fixtures, appliances, engines, circuit boards, and dishes. Hard surfaces may include, for example, sanitary care surfaces and food / plant / animal processing surfaces.

[0071] Surprisingly, it was found that certain combinations of (fragrance) enhancers as specified herein are effective for improving the fragrance intensity and the adhesion of odorous substances. In addition, it was found that these substances are very suitable for malodor reduction and at least enhance the malodor reducing effect of antimicrobial substances. With regard to the coverage of malodors and the prevention of their formation, further advantageous effects were found. Therefore, the combination of odorous substances with the fragrance enhancing mixture as specified herein is preferably used for improving the olfactory properties of odorous substances and / or for enhancing the adhesion of odorous substances and / or for malodor reduction.

[0072] Based on the favorable effect on malodor and fragrance intensity, the composition according to the invention is suitable as or for malodor management, or for adjusting the fragrance profile, or for changing the fragrance profile. The composition according to the invention provides excellent effects for adjusting, changing or suppressing undesirable fragrance profiles.

[0073] In the context of the present invention, the term "malodor covering" (or malodor masking) means that the unpleasant odor of one or more substances or compositions is completely suppressed or reduced, but this covering is not achieved by the beneficial intrinsic odor of the added compound. Usually, the unpleasant odor of a substance or composition is improved by adding a compound that exhibits a malodor covering effect, however, due to the beneficial intrinsic odor of the added compound, the added compound does not improve the unpleasant odor of the substance or composition. The added compound is an odor-neutral molecule without a beneficial intrinsic odor. Therefore, in the context of the present invention, the term "malodor covering" does not relate to a fragrance compound or composition that only covers an unpleasant odor due to a strong beneficial intrinsic odor.

[0074] In the context of the present invention, the term "malodor management" means that the formation of unpleasant odors is completely suppressed or inhibited (preventing the formation of malodors) and / or that already existing unpleasant odors are completely suppressed or at least reduced ("malodor reduction"). For example, the formation of unpleasant odors can be suppressed or inhibited by suppressing or inhibiting microbial activity. Therefore, "malodor management" can be achieved by suppressing the generation of malodors and / or reducing malodors.

[0075] In the context of the present invention, malodor reduction / masking / preventive effect means that the olfactory perception that is usually caused by particularly odorous substances and that is unpleasant to most people is perceptibly reduced, covered or even suppressed. Therefore, this reduction is not just based on masking by strong fragrances.

[0124] The odorous substances specified above can be used alone or in the form of a mixture of two, three or even more odorous substances from the same type (natural, synthetic, ethers, esters, etc.) or as a mixture of odorous substances of different types. This means that the fragrance substances specified above can be used in a large number of fragrance mixtures as individual substances or in the form of a mixture with at least one, two, three or even more fragrance substances, which are selected from a wide range of natural and synthetic substances.

[0125] For the detergent and / or cleaning compositions according to the invention, the list of odoriferous substances (b1, b2, b3, b) specified herein can be combined arbitrarily with the list of surfactants specified herein and the list of (fragrance) enhancers as specified herein.

[0126] In the detergent and / or cleaning composition, the odorous substance or the mixture of odorous substances is preferably contained in an amount of about 0.00001% to 10% by weight, preferably 0.0001% to 5% by weight, particularly preferably 0.001% to 2% by weight, relative to the total amount of the detergent and / or cleaning composition.

[0127] Fragrance compositions containing at least one odoriferous substance can be used in liquid form, undiluted or diluted with a solvent. Suitable solvents for this purpose are, for example, ethanol, isopropanol, diethylene glycol monoethyl ether, glycerol, propylene glycol, 1,2-butylene glycol, dipropylene glycol, diethyl phthalate, triethyl citrate, isopropyl myristate, triacetin, vegetable oils, etc.

[0128] In addition, the fragrance composition containing one or more odorous substances can be adsorbed on a carrier, which ensures a fine distribution of the fragrance substances in the product and a controlled release when used. Such carriers can be porous inorganic materials, such as sodium sulfate, silica gel, zeolite, gypsum, clay, clay particles, aerated concrete, etc., or organic materials, such as wood, cellulose-based substances, sugars, dextrins (e.g. maltodextrin), or plastics, such as PVC, polyvinyl acetate or polyurethane. In addition, the one or more odorous substances can be provided in microencapsulated form, spray-dried form or as inclusion complexes or as extruded products.

[0129] The odoriferous substances can be encapsulated, for example, by coacervation with the aid of encapsulation materials, for example made of polyurethane or soft gelatin.

[0130] Spray-dried fragrance compositions can be produced, for example, by spray drying an emulsion or dispersion containing the fragrance substance composition, wherein modified starches, proteins, dextrins and vegetable gums can be used as carriers. Inclusion complexes can be prepared, for example, by introducing a dispersion of the fragrance substance composition and a cyclodextrin or urea derivative into a suitable solvent, such as water.

[0131] Extruded products may be produced by melting and extruding the fragrance material composition with a suitable waxy material, optionally followed by solidification in a suitable solvent such as isopropyl alcohol.

[0132] Enhanced composition or mixture / flavor enhancer / component (c) : The detergent and / or cleaning composition according to the invention further comprises at least one enhancing component / mixture / composition (c). These are also referred to as fragrance enhancers / components or fragrance enhancers / enhancing components or mixtures or compositions.

[0133] Reinforcer mixtures or reinforcing compositions (c) within the meaning of the present invention are (c1.1) 1,2-heptanediol, (c2.1) 2,3-heptanediol, (c3.1) mixtures of 1,2-heptanediol and 2,3-heptanediol, (c4.1) 1,2-heptanediol and 2,3-heptanediol. I ) at least one linear alkane diol having a carbon chain of 5 to 14 carbon atoms or a mixture comprising at least one first linear alkane diol having a carbon chain of 5 to 14 carbon atoms and one or more second linear alkane diols having a carbon chain of 5 to 14 carbon atoms different from the first linear alkane diol, and (c II ) caprylic acid glyceryl and / or (c III ) 4-hydroxyacetophenone and / or (c IV ) ethylhexylglycerol. Preferably, the reinforcing composition (c) within the meaning of the present invention is (c 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 and (c II ) caprylic acid glyceryl and / or (c III ) 4-hydroxyacetophenone and / or (c IV )Ethylhexylglycerin.

[0134] Therefore, the reinforcing component or the first reinforcing component of the mixture (c) in the composition [alkanediol component] according to the invention is preferably 1,2-heptanediol (c1.1) or 2,3-heptanediol (c2.1), or a mixture comprising two heptanediols, namely 1,2-heptanediol plus 2,3-heptanediol (c3.1).

[0135] Thus, reinforcing component (c) is based on a mixture of at least one (first) alkanediol reinforcing component ((first) reinforcing agent / component) as specified herein and at least one further or second reinforcing component (further or second reinforcing agent / component) selected from the group consisting of glyceryl caprylate, 4-hydroxyacetophenone, ethylhexylglycerin or any mixture of these further reinforcing agents.

[0136] Surprisingly, a mixture of at least one alkanediol and at least one of caprylic acid glyceride, 4-hydroxyacetophenone and / or ethylhexylglycerol shows excellent fragrance enhancement properties, i.e., even when a small amount of fragrance components is used without the need to add fixatives, etc., the intensity and adhesion of the fragrance contained in the detergent and / or cleaning composition are improved. At the same time, these enhancers provide improved malodor reduction and effectively prevent the formation of malodors and lead to improved cleaning performance. Based on these enhancing effects, the total amount of ingredients such as fragrances and other additives can be significantly reduced, thereby advantageously reducing the allergic potential of the final product formulation and its environmental impact. This improvement in properties is based on the synergistic interaction between at least one alkanediol (enhancer) and at least one other enhancer. In addition, this improvement in properties is based on the synergistic interaction between the enhancing component (c) and components (a) and (b).

[0137] More specifically, mixtures of these enhancers as specified above were found to be effective in enhancing or improving cleaning efficiency and at the same time intensifying the olfactory properties of odorous substances in a synergistic manner. Furthermore, these substances were found to be effective in improving the adhesion of odorous substances to substrates (such as clothing, fabrics, textiles, dishes, utensils, surfaces, etc.) treated with corresponding detergents and / or cleaning compositions while providing improved malodor reduction and / or malodor coverage and / or malodor prevention.

[0138] Furthermore, it has surprisingly been found that the substances of component (c) enhance the performance of conventional antimicrobial substances.

[0139] Alkanediol (c1.1), (c2.1), (c3.1), (c I ) The first component of the strengthening component or mixture (c) in the detergent and / or cleaning composition according to the invention [i.e. the alkanediol component] is preferably 1,2-heptanediol (c1.1) or 2,3-heptanediol (c2.1), or a mixture comprising two heptanediols, i.e. 1,2-heptanediol plus 2,3-heptanediol (c3.1).

[0140] 1,2-Heptanediol belongs to the class of alkanediols and is a straight chain alkanediol having the following general formula:

[0141] It has a carbon chain containing 7 carbon atoms, and the two functional OH-groups of the alkanediol are located in the α,β positions and are chemically bonded to the C1 and C2 carbon atoms in the alkanediol chain.

[0142] 2,3-Heptanediol also belongs to the class of alkanediols and is a straight-chain alkanediol having the following general formula:

[0143] It has a carbon chain containing 7 carbon atoms, and the two functional OH-groups of the alkanediol are located in the β,γ positions and are chemically bonded to the C2 and C3 carbon atoms in the alkanediol chain.

[0144] The first component [i.e., the alkanediol component] of the fragrance enhancing component (c) in the detergent and / or cleaning composition according to the present invention is selected from the group consisting of: (c I ) at least one linear alkane diol having a carbon chain of 5 to 14 carbon atoms, or a mixture comprising at least one first linear alkane diol having a carbon chain of 5 to 14 carbon atoms and one or more second linear alkane diols having a carbon chain of 5 to 14 carbon atoms different from the first linear alkane diol.

[0145] In an even more preferred variant, at least one linear alkanediol, at least one first linear alkanediol and / or one or more second linear alkanediols have a carbon chain length of 7 to 14 carbon atoms, and further preferably a carbon chain length of 7 to 12 carbon atoms, more preferably a carbon chain length of 7 to 10 carbon atoms, and most preferably a carbon chain length of 7 to 9 carbon atoms. The most preferred at least one linear alkanediol has a carbon chain of 7 or 8 carbon atoms. In combination with other (second) enhancing components selected from the group consisting of caprylic acid glyceride, 4-hydroxyacetophenone, ethylhexylglycerol or any mixture thereof, it was found that these alkanediols exhibit the best fragrance enhancement properties, i.e., strengthen the olfactory properties of odorous substances and their adhesion to substrates, while providing an improvement in malodor reduction / covering / prevention compared to short-chain alkanediols. For these alkanediols, a particularly significant enhancement effect was observed.

[0146] An alkanediol is a diol, any of a class of organic compounds belonging to the alcohol family; in the molecule of a diol, two hydroxyl (-OH) groups are attached to different carbon atoms of a carbon chain.

[0147] 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, therefore, like 1,2-pentanediol, 1,2-hexanediol and 1,2-heptanediol, are soluble in water and oil. In contrast, 1,2-octanediol is a solid and tends to precipitate or recrystallize in oily solutions and in ≥ 0.5% water. On the other hand, 1,2-decanediol is a solid and is only soluble in oil. In addition to moisturizing, some 1,2-alkanediols are used as viscosity modifiers.

[0148] The enhancer (c I ) in a first alternative is at least one linear alkanediol having a carbon chain of 5 to 14 carbon atoms, and preferably a carbon chain of 7 to 14 carbon atoms, and even more preferably a carbon chain of 7 to 12 carbon atoms, and more preferably 7 to 10 carbon atoms. Most preferably, the at least one linear alkanediol has a carbon chain of 7 to 9 carbon atoms, and further preferably has a carbon chain of 7 or 8 carbon atoms. For these alkanediols, a particularly pronounced reinforcing effect is observed.

[0149] Furthermore, in the second alternative, the reinforcing component (c I ) may include at least one first linear alkane diol in combination with one or more second linear alkane diols, preferably wherein at least one first linear alkane diol has a carbon chain of 5 to 14 carbon atoms (and preferably a carbon chain of 7 to 14 carbon atoms, further preferably a carbon chain of 7 to 12 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 further preferably a carbon chain of 7 or 8 carbon atoms), and at least one second linear alkane diol has a carbon chain of 5 to 14 carbon atoms (and preferably a carbon chain of 7 to 14 carbon atoms, further preferably a carbon chain of 7 to 12 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 further preferably a carbon chain of 7 or 8 carbon atoms). Therefore, the present invention also relates to a mixture comprising a first alkane diol and a second alkane diol as described herein.

[0150] Since the first linear alkanediol of the present invention can be selected from the same list and type of compounds as the linear alkanediol according to the first alternative, in the following, linear alkanediols are generally referred to, which may also be the first linear alkanediol. In a mixture of the first linear alkanediol and the second linear alkanediol, when they are particularly different, the specific terms "first" and "second" will be used to distinguish the two alkanediol components.

[0151] As used herein, the phrase "at least one linear alkane diol" or "at least one first linear alkane diol" means that the composition may contain one linear alkane diol having a carbon chain of 5 to 14 carbon atoms, or may contain one first linear alkane diol having a carbon chain of 5 to 14 carbon atoms, or may contain more than one linear alkane diol, or may contain more than one first linear alkane diol having a carbon chain of 5 to 14 carbon atoms, i.e., two, three, four or more different linear alkane diols or first linear alkane diols having a carbon chain of 5 to 14 carbon atoms.

[0152] The at least one linear alkanediol or the at least one first linear alkanediol according to the present invention consists of a chain of 5 to 14 carbon atoms (and preferably a carbon chain of 7 to 14 carbon atoms, further preferably a carbon chain of 7 to 12 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 further preferably a carbon chain of 7 or 8 carbon atoms) joined to each other by a single covalent bond, wherein the two OH functions are attached to two different carbon atoms in the chain.

[0153] The at least one linear alkanediol or the at least one first linear alkanediol having a carbon chain of 5 to 14 carbon atoms in the detergent and / or cleaning composition according to the invention is selected from the group consisting of pentanediol, hexanediol, heptanediol, octanediol, nonanediol, decanediol, undecanediol, dodecanediol, tridecanediol and tetradecanediol.

[0156] In a further preferred variant, at least one linear alkane diol or at least one first linear alkane diol has a carbon chain of 7 to 10 carbon atoms and is selected from the group consisting of heptanediol, octanediol, nonanediol and decanediol. In a most preferred variant, at least one linear alkane diol or at least one first linear alkane diol has a carbon chain of 7 to 9 carbon atoms and is selected from the group consisting of heptanediol, octanediol and nonanediol.

[0157] In a most preferred variant, in the detergent and cleaning composition according to the invention, at least one linear or at least one first linear alkanediol has a carbon chain of 7 or 8 carbon atoms and is selected from the group consisting of heptanediol, octanediol and nonanediol. Thus, in a more preferred variant, at least one linear alkanediol or at least one first linear alkanediol is selected from the group consisting of alkanediols having 7 and 8 carbon atoms, i.e. heptanediol, octanediol and any mixtures thereof.

[0158] In a still more preferred variant, the at least one linear alkanediol or the at least one first linear alkanediol is chosen from the group consisting of alkanediols having a higher number of carbon atoms of 9 to 14, i.e. nonanediol, decanediol, undecanediol, dodecanediol, tridecanediol, tetradecanediol and any mixtures thereof, or from the group consisting of alkanediols having a number of carbon atoms of 9 to 13, i.e. nonanediol, decanediol, undecanediol, dodecanediol, tridecanediol and any mixtures thereof, or from the group consisting of alkanediols having a number of carbon atoms of 9 to 12, i.e. nonanediol, decanediol, undecanediol, dodecanediol and any mixtures thereof, or from the group consisting of alkanediols having a number of carbon atoms of 9 to 11, i.e. nonanediol, decanediol, undecanediol and any mixtures thereof, or from the group consisting of alkanediols having a number of carbon atoms of 9 to 10, i.e. nonanediol, decanediol and any mixtures thereof.

[0160] In a still more preferred variant, the at least one linear alkanediol or the at least one first linear alkanediol is selected from the group consisting of heptanediol, octanediol and nonanediol.

[0161] In a most preferred variant, at least one linear alkanediol or at least the first linear alkanediol is heptanediol.

[0162] In a second alternative, the detergent and / or cleaning composition according to the invention comprises as a first enhancer a mixture comprising at least one first linear alkanediol having a carbon chain of 5 to 14 carbon atoms (and preferably a carbon chain of 7 to 14 carbon atoms, further preferably a carbon chain of 7 to 12 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 further preferably a carbon chain of 7 or 8 carbon atoms) and one or more second linear alkanediols having a carbon chain of 5 to 14 carbon atoms (and preferably a carbon chain of 7 to 14 carbon atoms, further preferably a carbon chain of 7 to 12 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 further preferably a carbon chain of 7 or 8 carbon atoms) different from the first linear alkanediol.

[0163] This means that the (first) flavor enhancer / component 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 may be any of the linear alkanediols described herein in general and in particular of the first alternative.

[0164] For example, the mixture may comprise one first linear alkane diol and one, two, three or more second linear alkane diols; or the mixture may comprise two first linear alkane diols and one, two, three or more second linear alkane diols, etc., provided that in each mixture, the first linear alkane diol and the second linear alkane diol are different from each other.

[0165] The second linear alkanediol preferably consists of a chain of 5 to 14 carbon atoms joined to each other by a single covalent bond, wherein the two OH functions are attached to two different carbon atoms in the chain.

[0166] The at least one second linear alkanediol having a carbon chain of 5 to 14 carbon atoms in the detergent and / or cleaning composition according to the invention is selected from the group consisting of pentanediol, hexanediol, heptanediol, octanediol, nonanediol, decanediol, undecanediol, dodecanediol, tridecanediol and tetradecanediol.

[0167] In a preferred variant, the at least one second linear alkanediol has a carbon chain of 7 to 14 carbon atoms and is selected from the group consisting of heptanediol, octanediol, nonanediol, decanediol, undecanediol, dodecanediol, tridecanediol and tetradecanediol.

[0168] In a further preferred variant, the at least one second linear alkanediol has a carbon chain of 7 to 12 carbon atoms and is selected from the group consisting of heptanediol, octanediol, nonanediol, decanediol, undecanediol and dodecanediol.

[0169] In a more preferred variant, the at least one second linear alkane diol has a carbon chain of 7 to 10 carbon atoms and is selected from the group consisting of heptanediol, octanediol, nonanediol and decanediol. In a most preferred variant, the at least one second linear alkane diol has a carbon chain of 7 to 9 carbon atoms and is selected from the group consisting of heptanediol, octanediol and nonanediol. In a most preferred variant, in the detergent and cleaning composition according to the first aspect of the invention, the at least one second linear alkane diol has a carbon chain of 7 or 8 carbon atoms and is selected from the group consisting of heptanediol and octanediol.

[0170] In a more preferred variant, the at least one second linear alkanediol is selected from the group consisting of heptanediol, octanediol and nonanediol.

[0171] The phrase "different from each other" means that the first linear alkane diol and the second linear alkane diol in the mixture differ in their carbon chain lengths (ie, the number of carbon atoms) or in their constitutional isomerism.

[0172] 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 structural isomerism or in their stereoisomerism.

[0173] If the first alkanediol and the second alkanediol are both, for example, heptanediol, then according to a second alternative, the second linear alkanediol, heptanediol, is a different constitutional isomer or stereoisomer than the first linear alkanediol.

[0174] In a preferred variant, the detergent and / or cleaning composition according to the invention comprises 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, wherein the number of carbon atoms of the first alkanediol and the second alkanediol is the same or different.

[0175] If both the first alkane diol and the second alkane diol have the same number of carbon atoms, this alkane diol combination is also referred to herein as a "homoalkane diol mixture" or a "homocombination." 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 constitutional isomerism or in their stereoisomerism.

[0176] If the first alkane diol and the second alkane diol have different numbers of carbon atoms, this alkane diol combination is also referred to herein as a "heterogeneous alkane diol mixture" or "heterogeneous combination". For example, the first linear alkane diol has a carbon chain of 7 carbon atoms and the second linear alkane diol has a carbon chain of 8 carbon atoms. However, in addition to this, the first linear alkane diol and the second linear alkane diol may differ in their constitutional isomerism or in their stereoisomerism.

[0177] In a preferred variant, the present invention relates to a detergent and / or cleaning composition, wherein the at least one linear alkanediol or the at least one first linear alkanediol is selected from the group consisting of pentanediol, hexanediol, heptanediol, octanediol, nonanediol, decanediol, undecanediol, dodecanediol, tridecanediol and tetradecanediol; and / or the one or more second linear alkanediols are selected from the group consisting of pentanediol, hexanediol, heptanediol, octanediol, nonanediol, decanediol, undecanediol, dodecanediol, tridecanediol and tetradecanediol.

[0178] Particularly preferred are (fragrance) enhancer mixtures wherein the at least one 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.

[0179] Most preferred are (fragrance) enhancer mixtures wherein the at least one first linear alkane diol is selected from the group consisting of pentanediol, hexanediol, heptanediol, octanediol and any mixtures thereof, and the one or more second alkane diols are selected from the group consisting of nonanediol, decanediol, undecanediol, dodecanediol, tridecanediol and any mixtures thereof.

[0180] The term "alkanediol" in the context of the present invention also includes its constitutional isomers or positional isomers. Constitutional isomers are compounds with the same molecular formula but different linkages. Positional isomers (a specific form of constitutional 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 in particular the position of the two alcohol functions.

[0181] 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)-constitutional isomer; (x,x+2)-constitutional isomer; (x,x+3)-constitutional isomer; etc. and α,ω-constitutional isomer (when the alcohol functional group is 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, and so on.

[0182] In the (x,x+1)-configurational isomer, the two OH functional groups are ortho-attached to two different adjacent carbon atoms in the chain. In the (x,x+2)-configurational 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 carbon atom. In the (x,x+3)-configurational 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 carbon atoms. In the α,ω-configurational isomer, the two functional groups are attached to the first carbon atom and the terminal carbon atom.

[0183] In a preferred variant of the detergent and / or cleaning composition according to the invention, the linear alkanediol having a carbon chain of 5 to 14 carbon atoms is preferably an vicinal (x,x+1)-diol selected from the group consisting of 1,2-diol, 2,3-diol, 3,4-diol, 4,5-diol, other (x,x+1)-diols and mixtures thereof, preferably the α,β-1,2-configurational isomers.

[0184] In a preferred variant of the detergent and / or cleaning composition according to the invention, at least one first linear alkanediol and / or one or more second linear alkanediols having a carbon chain of 5 to 14 carbon atoms are vicinal (x,x+1)-diols selected from the group consisting of 1,2-diols, 2,3-diols, 3,4-diols, 4,5-diols, other (x,x+1)-diols and mixtures thereof, preferably α,β-1,2-configurational isomers, and preferably the first linear alkanediol and / or the second linear alkanediol having a carbon chain of 5 to 14 carbon atoms are selected from 1,2-diols and / or 2,3-diols.

[0185] Thus, according to a preferred variant of the detergent and / or cleaning composition according to the invention, at least one linear alkanediol, at least one first linear alkanediol and / or one or more second linear alkanediols are (x,x+1) constitutional isomers, wherein x represents the number of carbon atoms in the alkanediol chain to which the OH groups of the alkanediol are chemically bonded, in particular 1,2-alkanediol, 2,3-alkanediol, 3,4-alkanediol or mixtures thereof, preferably 1,2-alkanediol or 2,3-alkanediol.

[0186] According to the present invention, vicinal (x,x+1)-diols are most preferred, such as α,β or β,γ or γ,δ, etc.

These substances have been found to effectively intensify the olfactory properties of odorous substances and at the same time provide improved adhesion of the odorous substances. Furthermore, they are effective in malodor reduction / masking / prevention. Furthermore, these substances were found to significantly improve the removal of stains and / or soils and show an overall improved cleaning performance. 2,3-Alkanediols with a relatively low number of carbon atoms are therefore effective as (fragrance) enhancers in detergents and / or cleaning compositions and / or for malodor covering and / or malodor reduction.

[0298] In a still more preferred variant, the at least one 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 their mixtures. any mixture 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 to 10 carbon atoms, i.e., 2,3-nonanediol, 2,3-decanediol and any mixture thereof.

[0301] It is found that these substances show better cleaning efficiency and fragrance enhancement properties. Therefore, 2,3-alkanediols with higher carbon atoms and more preferably more than 10 carbon atoms are effectively used as enhancers in detergents and / or cleaning compositions containing fragrance components within the meaning of the present invention. In terms of strength and adhesion, improved cleaning performance and improved fragrance performance all lead to better performance of detergents and / or cleaning compositions in washing or cleaning processes. For example, even when stored for a long time compared to a preparation that does not contain a enhancer mixture as specified herein, textiles treated with detergents and / or cleaning compositions according to the present invention show a significantly enhanced and prolonged fragrance impression. In addition, these compounds provide improved malodor coverage and / or malodor reduction.

[0302] In a particularly preferred variant, in the detergent and / or cleaning composition 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.

[0304] In the homoalkanediol mixture, the first linear alkanediol and the second linear alkanediol have the same number of carbon atoms.

[0305] 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.

[0306] Homoalkanediol mixtures comprising 1,2-nonanediol and 2,3-nonanediol or homoalkanediol mixtures comprising 1,2-decanediol and 2,3-decanediol or homoalkanediol mixtures comprising 1,2-undecanediol and 2,3-undecanediol are most preferred due to their significant enhancement effects in terms of fragrance performance and improved cleaning efficiency. In addition, the malodor covering and / or reducing properties are enhanced in a synergistic manner.

[0307] The homoalkanediol mixtures specified above according to the invention comprising 1,2-alkanediol and 2,3-alkanediol are characterized by a synergistic strengthening effect, i.e., the alkanediol mixtures exhibit increased cleaning performance and significant fragrance enhancement properties in terms of intensity and adhesion in a synergistic manner compared to their respective single 1,2-alkanediol or 2,3-alkanediol substances. In addition, the malodor covering and / or reducing properties are enhanced in a synergistic manner.

[0308] The synergistic effect or effect in improving cleaning efficiency and simultaneously enhancing fragrance performance is also found for homogeneous mixtures comprising 1,2-pentanediol and 2,3-pentanediol. Furthermore, the malodor covering and / or reducing properties are enhanced in a synergistic manner.

[0309] The synergistic effect of enhancing the intensity and adhesion of odorous substances is also observed for homogeneous mixtures comprising 1,2-hexanediol and 2,3-hexanediol. Furthermore, the malodor covering and / or reducing properties are enhanced in a synergistic manner.

[0310] A homogeneous mixture comprising 1,2-heptanediol and 2,3-heptanediol is particularly beneficial as it has a particularly pronounced synergistic enhancement effect on the fragrance performance and its adhesion properties in detergent and / or cleaning compositions. In addition, the malodor covering and / or reducing properties are enhanced in a synergistic manner.

[0311] Alkanediol mixtures comprising 1,2-octanediol and 2,3-octanediol or 1,2-nonanediol and 2,3-nonanediol are particularly advantageous because these mixtures are effective in synergistically enhancing odoriferous substances when used in detergent and / or cleaning compositions. In addition, the malodor masking and / or reducing properties are enhanced in a synergistic manner.

[0312] Furthermore, the alkanediol mixture comprising 1,2-decanediol and 2,3-decanediol or the alkanediol mixture comprising 1,2-undecanediol and 2,3-undecanediol synergistically enhances the fragrance properties of odoriferous substances in detergent and / or cleaning compositions. Furthermore, the malodor covering and / or reducing properties are enhanced in a synergistic manner.

[0313] A fragrance enhancement effect was also observed for an alkanediol mixture comprising 1,2-dodecanediol and 2,3-dodecanediol or an alkanediol mixture comprising 1,2-tridecanediol and 2,3-tridecanediol. Furthermore, the malodor covering and / or reducing properties were enhanced in a synergistic manner.

[0314] The above synergistic improvement in the performance of the fragrance component in terms of cleaning performance is particularly pronounced for homogeneous mixtures comprising 1,2-heptanediol and 2,3-heptanediol or homogeneous mixtures comprising 1,2-octanediol and 2,3-octanediol or homogeneous mixtures comprising 1,2-nonanediol and 2,3-nonanediol. In addition, the malodor coverage and / or reduction properties are enhanced in a synergistic manner.

[0315] The above-specified homoalkanediol mixtures comprising a 1,2-alkanediol and a corresponding 2,3-alkanediol show a significant synergistic enhancement effect and are significantly better than the corresponding 1,2-alkanediol or 2,3-alkanediol alone and at the same concentration.

[0336] Surprisingly, it was found that these 1,2-alkanediols are particularly suitable (fragrance) enhancers in terms of intensity and adhesion, which can also be effectively incorporated into detergents and / or cleaning compositions. It was found that these substances show better cleaning results and outstanding fragrance properties. For example, these improved properties were found for laundry detergents: even after long-term storage of the treated textiles, the textiles still show a high fragrance intensity. Compared with detergents and / or cleaning compositions without the addition of such substances, such detergents and / or cleaning compositions show improved cleaning and fragrance properties. In addition, improvements in malodors were observed.

[0337] According to a particularly preferred variant, the detergent and / or cleaning composition according to the invention comprises at least one (fragrance) enhancer selected from the group consisting of at least one linear 1,2-diol 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 different from the first linear 1,2-alkanediol.

[0338] Surprisingly, it was found that these 1,2-alkanediols having carbon chains of 7 to 14 carbon atoms are particularly effective fragrance enhancers, which can also be effectively incorporated into a wide range of detergents and cleaning compositions. In addition, it was found that these substances exhibit significant stain and / or soil removal enhancing properties in detergents and cleaning compositions. Thus, such detergents and / or cleaning compositions exhibit improved cleaning properties compared to detergents and / or cleaning compositions to which such substances are not added.

[0339] According to a particularly preferred variant, the detergent and / or cleaning composition according to the invention comprises at least one (fragrance) enhancer selected from the group consisting of at least one linear 1,2-diol 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 different from the first linear 1,2-alkanediol.

[0340] In a more preferred variant, the detergent and / or cleaning composition according to the invention comprises at least one (fragrance) enhancer selected from the group consisting of at least one linear 1,2-diol 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 1,2-alkanediol.

[0341] In a still more preferred variant, the detergent and / or cleaning composition according to the invention comprises at least one (fragrance) enhancer selected from the group consisting of at least one linear 1,2-diol 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 which are different from the first linear 1,2-alkanediol.

[0342] Surprisingly, it has been found that these long-chain alkanediols are particularly suitable (fragrance) enhancers in terms of intensity and adhesion, which can also be effectively incorporated into a wide range of detergent and / or cleaning compositions.

[0343] In addition, it was found that these substances show better cleaning results and outstanding fragrance properties. For example, these improved properties were found for laundry detergents: even after long-term storage of the treated textiles, the textiles still show high fragrance intensity. Compared with detergents and / or cleaning compositions without the addition of such substances, such detergents and / or cleaning compositions show significantly improved cleaning and fragrance properties. In addition, improvements in malodors were observed.

[0344] In a further preferred variant, the detergent and / or cleaning composition according to the invention comprises at least one (fragrance) enhancer 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.

[0345] The 1,2-alkanediol having a log Pow value of ≤ 1 is selected from the group consisting of 1,2-pentanediol (log Pow=0.06), 1,2-hexanediol (log Pow=0.58), 1,2-heptanediol (log Pow=0.9) and any mixture thereof. The 1,2-alkanediol is more soluble in water.

[0346] The Pow value is the partition coefficient of a compound for 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.

[0347] The log Pow value is a constant defined as follows: Log Pow = log10 (partition coefficient) Partition coefficient, P = [n-octanol] / [water] where [ ] indicates the concentration of solute in the organic and / or aqueous partitions.

[0348] The log Pow values ​​were determined at a standard temperature of 25°C.

[0349] A log Pow value ≤ 1 means that the compound has a higher affinity for the aqueous phase (more hydrophilic) and is therefore more soluble in water; a log Pow 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.

[0350] Surprisingly, it was found that within the meaning of the present invention, 1,2-alkanediols with a Pow value ≤ 1 are particularly suitable (fragrance) enhancers, which can also be effectively incorporated into a wide range of detergents and / or cleaning compositions. In addition, it was found that the aforementioned 1,2-alkanediols exhibit significantly improved cleaning properties in detergents and / or cleaning compositions and provide improved malodor reduction and / or coverage. Thus, detergents and / or cleaning compositions comprising 1,2-alkanediols with a Pow value ≤ 1 show improved olfactory properties compared to detergents and / or cleaning compositions without the addition of such 1,2-alkanediols.

[0351] In a further preferred variant, the detergent and / or cleaning composition according to the invention comprises at least one (fragrance) enhancer 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.

[0352] The 1,2-alkanediol having a log Pow value of ≥ 1 is selected from the group consisting of 1,2-octanediol (log Pow = 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.

[0353] Surprisingly, it was found that 1,2-alkanediols with a Pow value ≥ 1 are suitable (fragrance) enhancers that can also be effectively incorporated into a wide range of detergents and / or cleaning compositions and provide improved malodor reduction and / or coverage. In addition, it was found that the aforementioned 1,2-alkanediols exhibit significantly improved cleaning and fragrance properties in detergents and / or cleaning compositions. Thus, detergents and / or cleaning compositions comprising 1,2-alkanediols with a Pow value ≥ 1 show improved olfactory properties compared to detergents and / or cleaning compositions without the addition of such 1,2-alkanediols.

[0354] The term "alkanediol" in the context of the present invention also includes its stereoisomers. Stereoisomers are molecules with the same molecular formula and differ only in how their atoms are arranged in three-dimensional space.

[0377] At these mixing ratios, the above-mentioned alkanediol mixtures show a synergistically enhanced fragrance enhancement effect compared to the corresponding individual substances. This is also true for cleaning performance and malodor management.

[0378] A preferred variant according to the invention also encompasses mixtures 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 alkanediols used according to the present invention include petrochemically derived and bio-based natural and renewable raw material derived alkanediols. Preferably, the alkanediols are from bio-based sources and are therefore bio-alkanediols.

[0406] It has been found that the aforementioned combination comprising an odoriferous substance and a (fragrance) enhancer mixture as specified herein leads to excellent fragrance properties in detergent and / or cleaning compositions, i.e. the fragrance properties of such detergents and / or cleaning compositions are better in terms of intensity and adhesion than the fragrance properties of detergents and / or cleaning compositions not comprising the (fragrance) enhancer mixture as specified herein.

[0407] However, said combinations comprising a mixture of odoriferous components and (fragrance) enhancers not only have remarkable fragrance properties, but are also beneficial in laundry detergents, detergents for manual and automatic dishwashing, hard surface cleaners, cleaners for medical and dental instruments, stain removers and the like, since they exhibit enhanced cleaning activity as well as improved malodor reduction and / or coverage compared to detergents and / or cleaning compositions without the addition of said mixture of (fragrance) enhancers, and effectively allow the prevention of malodor formation, resulting in improved performance upon application.

[0408] It has surprisingly been observed that for detergent and / or cleaning compositions, the addition of a mixture of enhancers as specified above provides an effective fragrance enhancing effect when combined in a synergistic manner with odoriferous materials.

[0409] Particularly pronounced synergistic flavor enhancement effects and improvements as specified above can be observed for the following enhancers: ▪1,2-Heptanediol; ▪1,2-Octanediol; ▪1,2-nonanediol; In combination with at least one of the following other enhancers: ▪Glyceryl caprylate; ▪4-Hydroxyacetophenone; ▪Ethylhexylglycerin.

[0410] For the detergent and / or cleaning compositions according to the invention, the list of enhancers and mixtures thereof specified herein may be arbitrarily combined with the list of surfactants specified herein.

[0411] Optional components Antimicrobial agent / component (d), (d1), (d2), (d3) : The detergent and / or cleaning compositions may also contain one or more antimicrobial agents.

[0412] 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. If such agents are not added, the product will deteriorate, which can be manifested by odor changes, discoloration, mold growth, gas formation, emulsion separation or viscosity changes, making the product unacceptable to consumers.

[0413] Suitable antimicrobial agents include, but are not limited to, antimicrobial classes such as phenols, quaternary ammonium compounds, metal derivatives, amines, alkanolamines, nitro derivatives, anilines, 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, amine- 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 known in the art with antimicrobial properties. Other exemplary antimicrobial agents include glutaraldehyde, Bronopol (2-bromo-2-nitropropane-1,3-diol), silver and isothiazolone (such as methylisothiazolinone), lauroyl arginine ethyl ester hydrochloride (known under the trade name Neolone ™ (sold), sodium benzoate, benzyl alcohol or methyl benzyl alcohol.

[0414] In a preferred variant according to the invention, the detergent and / or 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 the detergent and / or cleaning composition to inhibit microbial spoilage and thus for stabilization purposes.

[0415] In particular, antimicrobial agents are added to liquid detergents and / or cleaners because they have a relatively high water content, which renders such compositions susceptible to microbial attack and growth.

[0416] If included in the detergent and / or cleaning compositions of the present invention, antimicrobial agents are preferably added in an amount of from about 0.001 wt. % to about 5 wt. %, based on the total weight of the composition.

[0417] The antimicrobial component is present in the composition according to the invention in an amount of 0.0001% to 15.0% by weight based on the total weight of the composition. In a preferred variant, the composition comprises an antimicrobial component in an amount of 0.001% to 10.0% by weight based on the total weight of the composition. In a particularly preferred variant, the antimicrobial component is advantageously used in the composition in an amount of 0.001% to 5.0% by weight based on the total weight of the composition.

[0418] Therefore, the detergent and / or cleaning composition according to the present invention preferably contains at least one antimicrobial compound in an amount of 0.0001% to 15.0% by weight, especially in an amount of 0.001% to 10.0% by weight, most especially in an amount of 0.001% to 5.0% by weight, based on the total weight of the composition.

[0419] The activity of these antimicrobial compounds is improved synergistically upon formulation of the composition according to the invention and in particular in a synergistic manner upon component (c) as specified herein.

[0420] Enzymes and enzyme stabilizers : The detergent and / or cleaning composition according to the invention may additionally comprise at least one enzyme or an enzyme preparation comprising at least one enzyme as a further component providing additional cleaning benefits.

[0421] Known enzyme is an effective chemical used 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 the desired activity of removing stains such as protein-based, carbohydrate-based or triglyceride-based from substrate. In addition, enzyme also helps to improve the washing result 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.

[0422] The enzyme that is suitable for detergent and / or cleaning composition can remove dirt or make dirt more removable by the surfactant or other components of cleaning composition by degrading or changing one or more types of dirt residues encountered on fabric or textile. The degradation and change of dirt residue can improve detergency by reducing the physicochemical force that dirt is bonded to the apparatus or device being cleaned, for example dirt becomes more soluble in water. For example, one or more proteases can be cut into simpler short-chain molecules by the complex, macromolecular protein structure present in the dirt residue, which are easier to be desorbed, dissolved or otherwise more easily removed by the washing solution containing the protease.

[0423] The stain removal enzymes according to the present invention have cleaning, stain removal or other beneficial effects as components of detergents and / or cleaning compositions for instruments, devices or equipment (such as medical or dental instruments, devices or equipment); or for laundry, textiles, warewashing, cleaning in place, drains, carpets, meat cutting tools, hard surfaces, personal care, etc.

[0424] Enzymes that can be used in accordance with the present invention include enzymes that provide the desired activity for: removing protein-based, carbohydrate-based or triglyceride-based stains from substrates; for cleaning, stain removal and disinfection pre-soaks, such as pre-soaks for medical and dental instruments, devices and equipment; for pre-soaks for pans, cooking utensils and tableware; or for pre-soaks for meat cutting equipment; for machine warewashing; for clothing 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; for pre-soaks for cleaning; and the like.

Preferred amylases are commercially available under the following trade names: Stainzyme ® and Amplify ® , each available from Novozymes; and Preferenz ® S, available from DUPONT / IFF.

[0429] Lipase Any lipase or lipase mixture from any source can be used in detergents and / or cleaning compositions, provided that the selected enzyme is stable in the desired pH range (about 6 to about 9). For example, the lipase can be derived from plants, animals or microorganisms, such as fungi or bacteria.

Preferred cellulases can be commercially available under the following trade names: Celluclean ® and Carezyme ® , each available from Novozymes; and Revitalenz ® , available from DUPONT / IFF.

[0431] Preferred enzyme selection depends on the conditions of the final application, including physical product form, use pH, use temperature and the type of soil to be degraded or altered, and is influenced by factors such as pH activity and / or optimum stability, thermostability and stability to active detergents, builders, etc. Enzymes can be selected to provide the best activity and stability for any given set of application conditions. In this regard, bacterial or fungal enzymes are preferred.

[0432] Proteases, amylases and lipases are the most commonly used enzymes in detergents and / or cleaning compositions. Proteases are particularly useful for cleaning protein-containing soils, such as eggs, milk, meat residues, etc. Amylases are particularly useful for removing starch-based soils, such as pasta and rice. Lipases are particularly useful for cleaning soils that include fats / greases.

[0433] 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 it is effective at the high temperatures of a dishwashing machine and is effective in reducing protein-based soils. Proteases are particularly useful for cleaning protein-containing soils such as blood, skin scales, mucus, grass, food (e.g., eggs, milk, spinach, meat scraps, tomato sauce), etc.

[0434] According to the present invention, the enzymes included in the detergent and / or cleaning composition can vary based on the specific cleaning application and the type of soil that needs to be cleaned. For example, the temperature of the specific cleaning application will affect the enzyme selected for use in the enzyme composition according to the present invention. For example, warewashing applications clean substrates at temperatures above about 60°C or above about 70°C or between about 65°C and 80°C, and enzymes (such as proteases) are desirable because they are able to maintain enzymatic activity at such elevated temperatures.

[0435] For example, laundry applications clean clothes at temperatures above about 40°C or above about 50°C or between about 65°C to 95°C, and enzymes such as proteases are desirable because they are able to maintain enzymatic activity at such elevated temperatures.

[0460] The oxidoreductase is selected from the group consisting of oxidases, oxygenases, catalases, peroxidases (such as haloperoxidases, chloroperoxidases, bromoperoxidases, lignin peroxidases or manganese peroxidases), dioxygenases or laccases (such as phenol oxidases and polyphenol oxidases) and any mixtures thereof.

[0461] Enzymes are not usually used in combination with bleaches in liquid detergents and / or cleaning compositions because they are unstable (enzyme denaturation), but in powder compositions percarbonate and enzymes are usually added.

[0462] Commercial enzymes are available in liquid or dry form (i.e., disks, powders, etc.), sold as raw aqueous solutions or in various purified, processed, and compounded forms established in the prior art, and include 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; it is assumed that the solid detergent and / or cleaning composition has the desired enzyme activity.

[0463] Preferably, the enzymes are added to the detergent and / or cleaning composition as a single enzyme preparation, as an enzyme cocktail preparation comprising a mixture of different enzymes or more preferably as a preparation mixed with stabilizers, preferably with one or more enzyme stabilizers, buffers and the like.

[0464] This includes, for example, solid enzyme preparations obtained by granulation, extrusion or freeze drying, or, particularly in the case of liquid or gel-like agents, enzyme solutions, advantageously concentrated as far as possible, low water content and / or the addition of stabilizers. Alternatively, for solid and liquid application forms, the enzyme can be encapsulated, for example by spray drying or extruding the enzyme solution together with a preferred natural polymer, or in capsule form, for example, those in which the enzyme is encapsulated, such as in a solidified gel, or in core-shell type, wherein the enzyme-containing core is coated with a protective layer that is impermeable to water, air and / or chemicals. In addition, other active substances (such as stabilizers, emulsifiers, pigments, bleaching agents or dyes) 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 due to the coating being storage-stable. In addition, two or more enzymes can be packaged together so that a single particle exhibits a variety of enzyme activities.

[0465] In a preferred variant according to the invention, the enzyme is added to the detergent and / or cleaning composition as a single enzyme.

[0466] In some other variants, the enzyme added to the detergent and / or cleaning composition is preferably an enzyme mixture of two, three, four or even more different enzymes. Typically, for laundry detergents, the enzyme mixture comprises two (preferably proteases and amylases) to six enzymes.

[0470] Typically, the enzyme is present in the detergent and / or cleaning composition 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 / or 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.

[0471] 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.

The enzyme is stabilized by the additional enzyme stabilizer by physical protection with the aid of a protective layer.

[0473] In a more preferred variant, at least one enzyme is added to the detergent and / or cleaning composition according to the invention as a mixture of an enzyme preparation with one or more stabilizers, preferably with one or more enzyme stabilizers, and optionally buffers, additives, etc. Suitable enzyme stabilizers are known to those skilled in the art.

[0499] Detergent and / or cleaning composition and product thereof According to a further aspect of the invention, the detergent and / or cleaning composition according to the invention is used as such (ie as a detergent and / or cleaning product) or for preparing a detergent and / or cleaning product or a detergent and / or cleaning preparation.

[0500] Surprisingly, it was found that the detergent and / or cleaning compositions of the present disclosure have superior cleaning performance and at the same time show effective malodor covering and / or malodor reducing properties compared to compositions without the addition of the enhancer mixture of the present invention. Furthermore, it was found that the compositions according to the present invention are effective in preventing malodor formation.

[0501] Furthermore, it was surprisingly found that the detergent and / or cleaning composition according to the invention enhances the olfactory properties of the odorous substances contained in the detergent and / or cleaning composition and / or the adhesion of the odorous substances compared to a composition without the addition of the enhancer mixture of the invention. Thus, even with small amounts of odorous components, the strength can be improved.

[0502] Furthermore, the malodor reduction and / or malodor covering properties of the detergent and / or cleaning composition are further improved based on the combination of at least one enhancing composition based on a combination of at least one alkanediol enhancer and at least one other enhancer selected from glyceryl caprylate, 4-hydroxyacetophenone, ethylhexylglycerin or any mixture of these other enhancers as specified herein, the surfactant component, the odoriferous fragrance component and optionally the additional antimicrobial component in a synergistic manner.

[0503] Surprisingly, it has been found that adding an effective amount of a mixture of at least one alkanediol as specified herein as a first reinforcing component and glyceryl caprylate, 4-hydroxyacetophenone, ethylhexylglycerol or any mixture thereof as defined herein as a second / other reinforcing component to a detergent and / or cleaning composition has a positive impact, as they synergistically enhance the cleaning efficiency and / or malodor reduction / masking of the detergent and / or cleaning composition and / or the olfactory properties of the odorous substances contained therein and / or the adhesion of the odorous substances contained therein. The fragrance substances in these detergents and / or cleaning compositions show superior olfactory properties in terms of intensity and adhesion compared to detergents and / or cleaning compositions without such reinforcing composition. Furthermore, it has been surprisingly found that the combination of an alkanediol component as a first reinforcing component and a second / other reinforcing component selected from glyceryl caprylate, 4-hydroxyacetophenone or ethylhexylglycerol or any mixture thereof synergistically enhances (or improves) the malodor reduction and / or malodor covering properties of the detergent and / or cleaning composition.

[0504] Thus, detergents and / or cleaning compositions containing a mixture of odoriferous substances or odoriferous substances with 1,2-heptanediol or 2,3-heptanediol or a mixture comprising 1,2-heptanediol and 2,3-heptanediol or a combination of at least one alkanediol as specified herein with caprylic acid glyceryl ester, 4-hydroxyacetophenone and / or ethylhexylglycerol as defined herein exhibit overall olfactory performance superior to detergents and / or cleaning compositions not containing such a fragrance enhancing composition (c).

[0505] Conversely, also due to the enhancing effect, the amount of fragrances and other ingredients used to enhance the fragrance performance or cleaning performance or malodor management performance in these detergents and / or cleaning compositions can be reduced while achieving similar cleaning results, i.e., without sacrificing fragrance performance or cleaning performance.

[0506] Furthermore, detergents and / or cleaning compositions containing an odorous substance or a mixture of odorous substances with 1,2-heptanediol or 2,3-heptanediol or a mixture comprising 1,2-heptanediol and 2,3-heptanediol or a combination of an alkanediol as specified herein with caprylic acid glyceryl ester, 4-hydroxyacetophenone and / or ethylhexylglycerol as defined herein exhibit improved malodor reduction properties and allow effective malodor coverage. Furthermore, it was found that these compositions are also able to prevent the formation of malodors.

[0507] Conversely, also due to the reinforcing effect, the amount of additives for improving the olfactory impression, such as malodor reducing agents, and other ingredients can be reduced without losing cleaning performance.

[0508] The combination of an enhancer selected from the group consisting of alkanediols and at least one other enhancing component selected from the group consisting of caprylic acid glyceride, 4-hydroxyacetophenone and ethylhexylglycerol in a detergent and / or cleaning composition provides an improved freshness and cleanliness feel. In particular, the detergent and / or cleaning composition according to the present invention is particularly beneficial in preventing or minimizing or covering malodors. It was surprisingly found that these enhancing components act in a synergistic manner.

[0520] As used herein, liquids include free-flowing liquids as well as pastes, gels, foams and mousses. Non-limiting examples of liquids include light and heavy duty liquid detergents and / or cleaning compositions, fabric strengtheners, detergent gels commonly used for laundry, bleaching agents and laundry additives. Gases (e.g., suspended bubbles) or solids (e.g., particles) may be contained in the liquid.

[0521] Solid as used herein 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.

[0522] Solid detergent and / or cleaning composition or product can be provided as pressed solid block, cast solid block, extruded pellet or block or tablet. In addition, solid detergent composition or product can be provided in the form of unit dose. Unit dose refers to the size of solid detergent and / or cleaning composition unit so that the whole unit is used during a single washing cycle.

[0523] Solid detergent and / or cleaning composition or product can also be provided in the form of multiple use (e.g., multiple use) solid, such as block or multiple pellets, and can be reused to produce an aqueous use solution of detergent composition for multiple cycles or a predetermined number of distribution cycles. The solid detergent composition used multiple times can be reused to produce an aqueous detergent composition, such as a use solution, for multiple washing cycles. The pressed solid detergent block is made suitable for providing stability so that the reactive components in the composition do not react with each other until dilution and / or use. In some aspects, the order in which the components are introduced to form a solid is non-restrictive because minimal water and / or no water is introduced into the solid composition. However, in some aspects, the pressed solid detergent block is prepared by using a bonding system to minimize any damage to the usable coated particles. Advantageously, the pressing process for preparing the pressed solid detergent block produces a pressed solid detergent block and prevents the reaction or mixing of the components. In one aspect of the present disclosure, the solid detergent composition remains unreacted or unmixed until use (e.g., dilution).

[0524] In a pressed solid process, a flowable solid, such as a granular solid or other particulate solid including a binder, is combined under pressure. In a pressed solid process, a flowable solid of the composition is placed in a mold (e.g., a die or container). The method may include gently squeezing the flowable solid in this form to produce a solid cleaning composition.

[0525] The detergent and / or cleaning composition or product can be provided in a concentrated form and diluted to a use solution or provided in a use solution form. Preferably, the use composition is diluted to a concentration of about 500 ppm to about 5000 ppm, more preferably about 750 ppm to about 4500 ppm, and most preferably about 1000 ppm to about 4000 ppm.

[0526] The detergent and / or cleaning composition or product according to the invention is used for household cleaning, medical cleaning, institutional cleaning (such as cleaning of schools, airports, hospitals) or industrial cleaning.

[0527] Detergents and / or cleaning compositions or products according to the present invention can be prepared by combining and mixing various ingredients according to conventional and known methods. Preferably, enzymes are added at the end 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 carried out. Detergents and / or cleaning agents such as detergent compositions can be prepared in intermittent or continuous processes.

[0528] Based on its aforementioned advantageous effects, the detergent and / or cleaning composition according to the present invention (which comprises a combination of at least one odorous substance and a fragrance enhancing composition based on a mixture of at least one alkanediol with caprylic acid glyceryl, 4-hydroxyacetophenone and / or ethylhexylglycerol) is particularly effective for enhancing the cleaning efficiency of the detergent and / or cleaning composition and / or enhancing the olfactory properties of the odorous substance contained therein and / or enhancing the adhesion of the odorous substance contained therein and / or for malodor reduction and / or malodor coverage and / or malodor prevention during washing and cleaning processes.

[0529] Therefore, in another aspect, the present invention relates to a method of treating a substrate, comprising the steps of: - treating a substrate with a detergent and / or cleaning composition or product according to the invention; and - Optionally rinsing the substrate in water to remove the composition or product.

[0530] Preferably, the method for treating a substrate is carried out in a washing apparatus or container containing a washing liquid comprising water and a detergent and / or cleaning composition or product according to the invention. The washing liquid may be applied to the substrate or the substrate may be immersed in the washing liquid.

[0531] The method alternatively comprises applying a detergent and / or cleaning composition or product (i.e. one that is insoluble in the absence of water) directly to part or all of the substrate in order to directly treat the substrate. This method is preferably a pre-treatment and can be subsequently treated with or in a wash liquor.

[0532] Surprisingly it has been found that the detergent and / or cleaning compositions according to the invention are suitable for a wide range of fabrics or textiles made of cotton, wool, silk and synthetic fibers (such as polyester, polyacrylic, viscose etc.) and provide an intense and lasting fragrance impression.

[0533] Preferably, the method is applied at low temperature. Preferably, the treatment temperature is below 50°C, and preferably below 40°C, and more preferably below 30°C.

[0534] Surprisingly, it has been found that the method according to the invention is particularly effective at such low temperatures.

[0535] Thus, the method allows for the removal of stains and / or soils in a low temperature range, in particular for temperature sensitive fabrics or textiles such as silk, wool, polyester, polyacrylic, viscose and the like.

[0536] The use of the detergent and / or cleaning composition or product according to the invention in the method according to the invention provides improved cleaning performance.

[0541] Due to the enhancing effect, the total amount of other additives in the detergent and / or cleaning composition can be reduced, and the use of other fragrances and additives (such as fixatives, etc.) can be almost eliminated or at least reduced, while providing an effective detergent and / or cleaning composition that achieves excellent cleaning performance and olfactory performance.

[0542] Surprisingly, it has been found that the addition of an effective amount of a mixture (c) / using an alkanediol, such as 1,2-heptanediol or 2,3-heptanediol or a mixture comprising 1,2-heptanediol and 2,3-heptanediol or a combination of at least one alkanediol as specified herein as an enhancer with a further enhancer selected from the group consisting of caprylic glyceride, 4-hydroxyacetophenone and / or ethylhexylglycerol as defined herein, to a detergent and / or cleaning composition has a positive and synergistic effect on the cleaning performance and effectively enhances the olfactory properties of the odorous substances, such as their intensity, and / or improves the adhesion of the odorous substances contained in the composition. At the same time, these substances allow effective malodor reduction and / or malodor coverage or even prevention of the formation of malodors. This excellent effect is based on the synergistic combination of odorous substances and fragrance enhancing compositions. This improvement also allows a reduction of fragrance compounds and their adjuvants in detergents and / or cleaning compositions, while providing a fresh, clean and hygienic odor impression, which is the basis for the effective cleaning performance of the compositions as disclosed herein.

[0543] The present invention therefore further relates to the use of a composition comprising as component (a) at least one surfactant, as component (b) at least one odoriferous substance, at least one flavor enhancing mixture (c) and optionally as component (d) at least one antimicrobial compound, the flavor enhancing mixture (c) comprising a mixture of: (c 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, and at least one other reinforcing agent selected from the group consisting of: (c II ) caprylic acid glyceryl ester, (c)(c III ) 4-hydroxyacetophenone, and / or (c IV ) Ethylhexylglycerin for enhancing the cleaning efficiency of detergents and / or cleaning compositions and / or for enhancing the olfactory properties of odorous substances and / or for enhancing the adhesion of odorous substances and / or for malodor reduction and / or for malodor covering and / or malodor prevention.

[0546] Finally, based on the advantageous effects, the present invention also relates to a method for enhancing the cleaning efficiency of a detergent and / or cleaning composition and / or enhancing the olfactory properties of odorous substances and / or enhancing the adhesion of odorous substances and / or malodor reduction and / or malodor coverage and / or malodor prevention, comprising the following steps: (i) providing a detergent and / or cleaning composition comprising at least one surfactant and at least one odoriferous substance; and (ii) adding thereto an effective amount of 1,2-heptanediol or a mixture of 2,3-heptanediol or a mixture comprising 1,2-heptanediol and 2,3-heptanediol; or (c I ) at least one reinforcing agent selected from the group consisting of at least one linear alkane diol having a carbon chain of 5 to 14 carbon atoms, or a mixture comprising at least one first linear alkane diol having a carbon chain of 5 to 14 carbon atoms and one or more second linear alkane diols having a carbon chain of 5 to 14 carbon atoms different from the first linear alkane diol, as defined herein; and at least one enhancer selected from the group consisting of: (c II ) Glyceryl caprylate; (c III )4-hydroxyacetophenone; (c IV )ethylhexylglycerin; and Any mixture thereof.

[0547] Finally, based on the advantageous effects, the present invention also relates to a method for enhancing the cleaning efficiency of a detergent and / or cleaning composition and / or enhancing the olfactory properties of odorous substances and / or enhancing the adhesion of odorous substances and / or malodor reduction and / or malodor coverage and / or malodor prevention, comprising the following steps: (i) providing a detergent and / or cleaning composition comprising at least one surfactant and at least one odoriferous substance; and (ii) adding thereto an effective amount of a mixture (c), wherein the mixture (c) comprises or consists of: (c I ) at least one reinforcing agent selected from the group consisting of at least one linear alkane diol having a carbon chain of 5 to 14 carbon atoms, or a mixture comprising at least one first linear alkane diol having a carbon chain of 5 to 14 carbon atoms and one or more second linear alkane diols having a carbon chain of 5 to 14 carbon atoms different from the first linear alkane diol, as defined herein; and at least one enhancer selected from the group consisting of: (c II ) Glyceryl caprylate; (c III )4-hydroxyacetophenone; (c IV )ethylhexylglycerin; and Any mixture of these other enhancers.

[0548] With regard to the one or more fragrance substances / one or more odorous substances and preferred variants thereof, reference is made to the previous description of the one or more odorous substances of the detergent and / or cleaning composition according to the invention, which is equally valid with regard to the use of at least one fragrance enhancing composition (or mixture) (c) for enhancing the cleaning efficiency of the detergent and / or cleaning composition and / or for enhancing the olfactory properties of the odorous substance and / or for enhancing the adhesion of the odorous substance and / or for malodor reduction and / or for malodor covering and / or malodor prevention.

The fragrance in these detergents and / or cleaning compositions shows a significant intensity and adhesion compared to detergents and / or cleaning compositions without such fragrance enhancing composition. Furthermore, the synergistic combination of the (fragrance) enhancer of the present invention with the odorous substance or mixture of odorous substances improves the malodor reduction and / or malodor coverage of the detergent and / or cleaning composition compared to detergents and / or cleaning compositions without said (fragrance) enhancer mixture.

[0551] Conversely, also due to the potentiating effect, the amount of fragrance or other ingredients used to enhance / improve the scent impression in these detergents and / or cleaning compositions can be reduced to achieve a similar odor effect.

[0552] 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.

[0553] Example Example 1 : The following tests were conducted to show the enhancing effect of the enhancers as specified herein in commercial liquid detergent and / or cleaning compositions in terms of cleaning performance and improvement in fragrance intensity as well as enhanced adhesion of fragrance materials on corresponding substrates.

[0554] In parallel, comparative tests were carried out on corresponding compositions under the same conditions, but without the mixture of the first reinforcing component according to the invention with the further (second) reinforcing components as specified herein.

[0555] 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.

[0556] The cleaning performance test consists of evaluating the stain removal efficiency of the tested laundry detergents on 14 stains.

[0557]

[0558] Each stain was measured / rated before washing (to verify the quality of the stain) and after washing.

[0559] The degree of stain removal can be assessed by: (A) Visual inspection by the team; (B) Determine the stain removal index (SRI) whiteness W using a spectrophotometer or a digital image analysis system.

[0560] Sensory evaluation was used to determine the fragrance intensity as well as the malodor reduction. The sensory evaluation was performed by a trained panel.

[0561] Based on spectroscopic or visual measurements via the panel, the extent of stain removal and thus cleaning performance can be determined.

[0562] Results were statistically analyzed using Tukey's HSD test (HSD = Honestly Significant Difference) with a 95% confidence level. The HSD values ​​highlight significant differences between each pair of products.

[0563] Sensory evaluation The degree of malodour reduction or malodour coverage and / or fragrance intensity and / or fragrance adhesion is then tested and evaluated by a trained panel in an established setting.

[0564] To evaluate malodor coverage / reduction, a defined amount of the composition is applied to a filter paper together with a defined amount of sweat odor. Alternatively, the textile sample is treated with sweat odor and subsequently washed with a detergent and / or cleaning composition.

[0565] Fragrance intensity and adhesion were rated on a scale of 1 (no odor) to 6 (very strong), or alternatively in a blind evaluation on a scale of 1 to 10. Alternatively, for malodor evaluation, panelists were asked to rate individual samples on a scale of 0 to 10 (0: no odor; 10: strongest imaginable). Cleaning performance was determined visually by panelists on a scale of 1 (no cleaning) to 10 (complete removal).

[0566] The results indicate that compositions comprising a surfactant, an odoriferous material, an effective amount of 1,2-heptanediol and / or 2,3-heptanediol or a potentiated mixture of an alkanediol as specified herein and glyceryl caprylate, 4-hydroxyacetophenone and / or ethylhexylglycerin are particularly useful for malodor reduction and / or malodor masking based on a synergistic malodor reduction / masking effect.

[0567] At the same time, the fragrance intensity of the odoriferous component is enhanced in a synergistic manner. Furthermore, the combination of alkanediols as enhancers with further enhancers selected from the group consisting of glyceryl caprylate, 4-hydroxyacetophenone and / or ethylhexylglycerol leads to a synergistically improved adhesion of the fragrance component on surfaces and textiles treated with the composition of the invention.

[0568] Furthermore, the results show that alkanediols having a carbon chain of 7 to 14 carbon atoms produce particularly good flavor enhancing properties when combined with other enhancers selected from the group consisting of glyceryl caprylate, 4-hydroxyacetophenone and / or ethylhexylglycerol compared to shorter chain alkanediols.

[0569] Finally, it was found that the combination of the first reinforcing component based on alkanediols and other second reinforcing comp...
