Description

Technical Field

[0001] Cross - Reference to Related Applications This application claims priority under 35 U.S.C. § 119 to Provisional Patent Application No. 62 / 582,652, filed on November 7, 2017, which is hereby incorporated by reference in its entirety.

[0002] The present invention relates to a method for cleaning waxy, oily, and / or fatty stains, including lip cosmetic stains such as lipstick and lip gloss. Specifically, the removal of lip cosmetic stains, including lipstick and lip gloss stains, in utensil cleaning, pre - treatment, and hard - surface cleaning is disclosed through the use of solid and / or liquid cleaning compositions containing long - chain polyamines, i.e., C6 - C20 polyamines having 1 - 5 nitrogens, regardless of the presence or absence of an alkali source. Preferred alkaline cleaning compositions include sodium hydroxide detergents containing N1-(3 - aminopropyl)-N3 - dodecylpropane - 1,3 - diamine and / or N1,N1,N3 - tris(3 - aminopropyl)-N3 - dodecylpropane - 1,3 - diamine.

Background Art

[0003] Various utensils, including drinking utensils in restaurants and bars, are often soiled at the top with lip cosmetic stains that customers transfer from their lips to the drinking utensils when sipping from the glass. Lip cosmetic stains are very difficult to remove typically due to the waxy, oily, and / or fatty consistency of lip cosmetics. As a result of advancements in the lip cosmetic industry in recent years, such as new "long - lasting" lipsticks, the removal of lip cosmetic stains has become even more difficult.

[0004] Previously, drinking utensils have undergone various cleaning processes depending on the specific method of use. Pretreatment or immersion has been used to remove lip cosmetic stains or to loosen dirt before subjecting the drinking utensils to a normal cleaning cycle. In many cases, these pretreatments require the utensils to be turned over to come into contact with the dirt. Additional processes include, for example, re-washing the utensils, manually washing or scrubbing the utensils, and / or adding additional time to the utensil cleaning cycle to remove such dirt.

[0005] Utensil cleaning formulations using alkali metal carbonates, alkali metal metasilicates, alkali metal silicates, and / or alkali metal hydroxides are known to provide effective cleaning power, especially when used in combination with phosphorus-containing compounds. However, the use of phosphorus raw materials in detergents has become undesirable for various reasons, including environmental reasons. This has led to strict regulation of phosphorus-based chemicals. Therefore, the industry is seeking alternative methods to clean utensils and control the formation of hard water scale associated with highly alkaline detergents. Many commercially available detergent formulations use sodium tripolyphosphate as a cost-effective component to control hard water scale and provide cleaning power. However, since the formulations are adapted to contain less than 0.5% by weight of phosphorus, there is a need to identify replacement cleaning components. Many non-phosphate replacement formulations result in the accumulation of severe dirt on hard surfaces.

Summary of the Invention

Problems to be Solved by the Invention

[0006] Therefore, it is an object to develop improved solid and / or liquid cleaning compositions for the effective removal of waxy, oily, and / or fatty dirt, including lip cosmetic dirt.

[0007] A further object is to provide improved utensil cleaning, pretreatment, and hard surface cleaning compositions.

[0008] A further object is to provide a cleaning composition that does not require the use of a pretreatment step for immersing lip cosmetic stains on drinking utensils.

Furthermore, it should be understood that all technical terms used herein are for the sole purpose of describing specific embodiments and are not intended to limit in any way or scope. For example, as used in this specification and the appended claims, the singular forms "a", "an", and "the" may include plural referents unless the context clearly dictates otherwise. Additionally, all units, prefixes, and symbols can be expressed in their SI acceptable form.

[0021] The numerical ranges recited herein include numbers within the defined ranges. Throughout this disclosure, various aspects of the invention are presented in range format. The description in range format is for convenience and brevity only and should not be construed as an inflexible limitation on the scope of the invention. Thus, the description of a range should be considered to specifically disclose all possible subranges as well as the individual numerical values within that range (e.g., 1-5 includes 1, 1.5, 2, 2.75, 3, 3.80, 4, and 5).

[0022] To make the present invention more readily understood, certain terms are first defined. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which embodiments of the present invention pertain. Many methods and materials similar to, modified from, or equivalent to those described herein can be used in the practice of embodiments of the present invention without undue experimentation, and the preferred materials and methods are described herein. When describing and claiming embodiments of the present invention, the following terms are used in accordance with the definitions set forth below.

[0023] As used herein, the term "about" refers to variations in quantity that can occur, for example, due to inadvertent error in these procedures, by the typical measurements and liquid handling procedures used to make concentrates or use solutions in the real world, and by differences in the manufacture, source, or purity of the ingredients used in the preparation of the compositions or the practice of the methods. The term "about" also encompasses different amounts resulting from different equilibrium conditions for the compositions arising from a particular initial mixture. Whether or not modified by the term "about", the claims include equivalents of that amount.

[0024] The terms "active substance", "percent active substance", "weight percent active substance", or "active substance concentration" are used interchangeably herein and refer to the concentration of the components involved in washing, expressed as a percentage after subtracting inert components such as water or salts.

[0025] As used herein, the term "alkyl" or "alkyl group" refers to a saturated hydrocarbon having one or more carbon atoms, including straight-chain alkyl groups (e.g., methyl, ethyl, propyl, butyl, pentyl, hexyl, heptyl, octyl, nonyl, decyl, etc.), cyclic alkyl groups (or "cycloalkyl" or "alicyclic" or "carbocyclic" groups) (e.g., cyclopropyl, cyclopentyl, cyclohexyl, cycloheptyl, cyclooctyl, etc.), branched-chain alkyl groups (e.g., isopropyl, tert-butyl, sec-butyl, isobutyl, etc.), and alkyl-substituted alkyl groups (e.g., alkyl-substituted cycloalkyl groups and cycloalkyl-substituted alkyl groups).

[0026] Unless otherwise specified, the term "alkyl" includes both "unsubstituted alkyl" and "substituted alkyl". As used herein, the term "substituted alkyl" refers to an alkyl group having a substituent that replaces one or more hydrogens of one or more carbons of the hydrocarbon backbone. Such substituents include, for example, alkenyl, alkynyl, halogeno, hydroxyl, alkylcarbonyloxy, arylcarbonyloxy, alkoxycarbonyloxy, aryloxy, aryloxycarbonyloxy, carboxylate, alkylcarbonyl, arylcarbonyl, alkoxycarbonyl, aminocarbonyl, alkylaminocarbonyl, dialkylaminocarbonyl, alkylthiocarbonyl, alkoxyl, phosphate, phosphonate, phosphinate, cyano, amino (including alkylamino, dialkylamino, arylamino, diarylamino, and alkylarylamino), acylamino (including alkylcarbonylamino, arylcarbonylamino, carbamoyl, and ureido), imino, sulfhydryl, alkylthio, arylthio, thiocarboxylate, sulfate, alkylsulfinyl, sulfonate, sulfamoyl, sulfonamide, nitro, trifluoromethyl, cyano, azide, heterocyclic, alkylaryl, or aromatic (including heteroaromatic) groups.

[0028] The "anti-redeposition agent" refers to a compound that helps remain suspended in water instead of redepositing on the object being washed. The anti-redeposition agent is useful in the present invention to assist in reducing the redeposition of the removed dirt onto the cleaned surface.

[0029] As used herein, the term "washing" refers to a method used to promote or assist in dirt removal, bleaching, reduction of the microbial population, rinsing, and any combination thereof. As used herein, the term "microorganism" refers to any acellular or unicellular (including colonies) organism. Microorganisms include all prokaryotes. Microorganisms include bacteria (including cyanobacteria), spores, lichens, fungi, protozoa, virinos, viroids, viruses, phages, and some algae. As used herein, the term "microbe" is synonymous with "microorganism".

[0030] The term "commercially acceptable cleaning performance" generally refers to the degree of cleanliness, effort, or both that a typical consumer might expect to achieve or consume when using a cleaning product or cleaning system to address typical soil conditions on typical substrates. This degree of cleanliness may correspond to a general absence of visible soil or a somewhat lower degree of cleanliness, depending on the particular cleaning product and the particular substrate. Cleanliness can be evaluated in various ways depending on the particular cleaning product being used (e.g., dishwashing detergent) and the particular hard or soft surface being cleaned (e.g., dishes, etc.), and is typically determined using generally agreed-upon industry standard tests or localized variations of such tests. In the absence of such generally agreed-upon industry standard tests, the cleaning performance of phosphorus-containing cleaning products sold in connection with that brand may be evaluated using tests already adopted by the manufacturer or seller.

Solids can have various degrees of shape stability, but typically do not flow appreciably and substantially retain their shape under moderate stress, pressure, or merely gravity, for example when a shaped solid is removed from a mold or an extruded solid exits an extruder. Solids can have various degrees of surface hardness and can range, for example, from those of a molten solid block with a relatively high density and hard surface, similar to concrete, to those of a cured caulking material, to those characterized as malleable and sponge-like.

[0038] As used herein, the term "substantially free of" refers to a composition that either completely lacks a component or has such a small amount of a component that the component does not affect the performance of the composition. The component may be present as an impurity or as a contaminant and must be less than 0.5% by weight. In another embodiment, the amount of the component is less than 0.1% by weight, and in yet another embodiment, the amount of the component is less than 0.01% by weight.

[0039] The term "substantially similar cleaning performance" generally refers to being achieved by a substitute cleaning product or substitute cleaning system that generally has the same degree of cleaning power (or at least not a significantly inferior degree) or generally consumes the same amount of labor (or at least not a significantly inferior consumption).

[0040] As used herein, the term "articles" refers to items such as eating and cooking utensils, dinnerware, glasses, and other hard surfaces.

Other exemplary plastics that can be cleaned using the compounds and compositions of the present invention include polyethylene terephthalate (PET), polystyrene, and polyamide.

[0041] The terms "weight percent", "wt-%", "percent by weight", "% by weight", and variations thereof, as used herein, refer to the concentration of a substance obtained by dividing the weight of the substance by the total weight of the composition and multiplying by 100. It is understood that when used herein, terms such as "percent", "%", etc. are intended to be synonymous with "weight percent", "wt-%", etc.

[0042] The methods and compositions of the present invention may comprise, consist essentially of, or consist of the components and ingredients described in the present invention, as well as other ingredients described herein. As used herein, "consisting essentially of" means that a method or composition may include additional steps, components, or ingredients only if such additional steps, components, or ingredients do not materially alter the basic and novel characteristics of the methods and compositions recited in the claims.

[0043] Detergent composition Embodiment Exemplary ranges of detergent compositions are shown in Tables 1A - 1E in weight percentages of solid and / or liquid detergent compositions, including both concentrates and ready-to-use compositions for various uses. [Table 1] [Table 2] [Table 3] [Table 4] [Table 5]

[0044] The cleaning composition can include a concentrated solid and / or liquid composition, or can be diluted to form a use composition, and can be a composition that is ready for immediate use. Generally, a concentrate refers to a composition that is intended to be diluted with water to provide a use solution that contacts an object to provide desired cleaning, rinsing, etc. The cleaning composition that contacts the article or implement to be cleaned can be referred to as a concentrate or a use composition (or use solution) depending on the formulation used in the method. It should be understood that the concentrations of the long-chain polyamide and other components will vary depending on whether the cleaning composition is provided as a concentrate or a use solution.

[0045] The use solution can be prepared from the concentrate by diluting the concentrate with water at a dilution ratio that provides a use solution having the desired cleaning characteristics. The water used to dilute the concentrate to form the use composition can be referred to as dilution water or a diluent and can vary by location. Typical dilution factors will be from approximately 1 to approximately 10,000, but will depend on factors such as the hardness of the water, the amount of dirt to be removed, etc. In one embodiment, the concentrate is diluted at a ratio of the concentrate to water of from about 1:10 to about 1:10,000. Specifically, the concentrate is diluted at a ratio of the concentrate to water of from about 1:100 to about 1:5,000. More specifically, the concentrate is diluted at a ratio of the concentrate to water between about 1:250 and about 1:2,000.

[0046] In one aspect, the use solution of the cleaning composition has an alkalinity of from about 0 ppm to about 2000 ppm (since some embodiments of the composition do not require an alkali source for removing lipstick stains) and from about 10 ppm to about 250 ppm of long-chain polyamine. In a preferred aspect, the use solution of the cleaning composition has an alkalinity of from about 100 ppm to about 2000 ppm and from about 10 ppm to about 200 ppm of long-chain polyamine. In a preferred aspect, the use solution of the cleaning composition has an alkalinity of from about 500 ppm to about 1500 ppm and from about 100 ppm to about 200 ppm of long-chain polyamine. In a preferred aspect, the use solution of the cleaning composition has an alkalinity of from about 750 ppm to about 1250 ppm and from about 100 ppm to about 200 ppm of long-chain polyamine. Additionally, without being limiting in accordance with the present invention, all recited ranges include the numbers defining the ranges and include each integer within the defined ranges.

[0047] alkali source In some embodiments, the composition comprises an effective amount of one or more alkali sources. In other embodiments, the composition does not contain an alkali source and can unexpectedly provide effective soil removal. In compositions using an alkali source, the effective amount of one or more alkali sources needs to be considered as the amount that provides a composition having a pH of about 7 to about 14. In certain embodiments, the cleaning composition has a pH of about 7.5 to about 13.5. In certain embodiments, the cleaning composition has a pH of about 8 to about 13. During the cleaning cycle, the use solution has a pH of about 8 to about 13. In certain embodiments, the use solution has a pH of about 9 to 11. Examples of suitable alkali sources for the cleaning composition include, but are not limited to, carbonate-based alkali sources containing carbonates such as alkali metal carbonates, and caustic-based alkali sources containing alkali metal hydroxides. Other suitable alkali sources can include metal silicates, metal borates, and organic alkali sources. Exemplary alkali metal carbonates that can be used include, but are not limited to, sodium carbonate, potassium carbonate, bicarbonates, sesquicarbonates, and mixtures thereof. Exemplary alkali metal hydroxides that can be used include sodium hydroxide, lithium hydroxide, or potassium hydroxide. Exemplary metal silicates that can be used include, but are not limited to, sodium silicate or potassium silicate or metasilicate. Exemplary metal borates include, but are not limited to, sodium borate or potassium borate.

[0048] Organic alkali sources are often strong nitrogen bases, for example, ammonia (ammonium hydroxide), amines, alkanolamines, and amino alcohols. Typical examples of amines include primary, secondary, or tertiary amines having a hydrocarbon group linked to at least one nitrogen, and diamines, where the hydrocarbon group is a saturated or unsaturated straight-chain or branched alkyl group having at least 10 carbon atoms and preferably 16 - 24 carbon atoms, or an aryl, aralkyl, or alkaryl group containing up to 24 carbon atoms, and any other group linked to nitrogen is formed by an optionally substituted alkyl group, aryl group, or aralkyl group, or a polyalkoxy group. Typical examples of alkanolamines include monoethanolamine, monopropanolamine, diethanolamine, dipropanolamine, triethanolamine, tripropanolamine, etc. Typical examples of amino alcohols include 2-amino-2-methyl-1-propanol, 2-amino-1-butanol, 2-amino-2-methyl-1,3-propanediol, 2-amino-2-ethyl-1,3-propanediol, hydroxymethylaminomethane, etc.

[0049] Generally, the alkali source is generally available in either aqueous or powder form, both of which are useful for formulating the detergent composition. The alkali can be added to the composition in any form known in the art, including solid beads, granular or particulate form, which dissolve in an aqueous solution, or a combination thereof.

[0050] Generally, the cleaning composition is expected to contain an alkali source(s) in an amount of about 0 wt% to about 99 wt%, about 0.005 wt% to about 95 wt%, about 0.01 wt% to about 90 wt%, about 0.015 wt% to about 90 wt%, about 10 wt% to about 90 wt%, about 20 wt% to about 90 wt%, about 40 wt% to about 90 wt%, about 50 wt% to about 90 wt%, and about 50 wt% to about 85 wt% of the total weight of the detergent composition. When diluted in a use solution, the composition of the present invention may contain about 0 ppm to about 4000 ppm of an alkali source, about 10 ppm to about 4000 ppm of an alkali source, preferably about 100 ppm to about 1500 ppm, and most preferably about 100 ppm to 1000 ppm. Additionally, without being limited to the present invention, all ranges recited include the numbers defining the range and include each integer within the defined range.

[0051] Long-chain polyamine The composition contains an effective amount of one or more long-chain polyamines. As referred to herein, long-chain polyamines include C6-C20 amines, preferably C6-C18 polyamines, preferably C6-C12 polyamines, preferably C12-C20 polyamines, preferably C12-C18 polyamines, or preferably C18-C20 polyamines. The long-chain polyamines suitable for use in the composition can be branched or unbranched. In a preferred embodiment, the long-chain polyamines suitable for use in the composition are unbranched straight-chain amines having no aromatic functional groups in their structure. In a preferred embodiment, the long-chain polyamines suitable for use in the composition are unbranched straight-chain amines having 1 to 5 nitrogens.

[0052] Exemplary C6-C20 polyamines include N1-(3-aminopropyl)-N3-dodecylpropane-1,3-diamine [I] and N1,N1,N3-tris(3-aminopropyl)-N3-dodecylpropane-1,3-diamine [II], each having the formula shown below.

Chemical formula

[0053] In one aspect, the composition comprises from about 0.0005 wt% to about 99 wt% of a long-chain polyamine, from about 0.0005 wt% to about 50 wt% of a long-chain polyamine, from about 0.001 wt% to about 30 wt% of a long-chain polyamine, from about 0.005 wt% to about 20 wt% of a long-chain polyamine, from about 0.01 wt% to about 10 wt% of a long-chain polyamine, from about 1 wt% to about 30 wt% of a long-chain polyamine, from about 1 wt% to about 20 wt% of a long-chain polyamine, or preferably from about 0.1 wt% to about 10 wt% of a long-chain polyamine. Additionally, without limiting to what is according to the present invention, all ranges recited include the numbers defining the range and include each integer within the defined range.

[0054] In a cleaning composition that contains an alkali source or has no alkali source, the composition has a pH that is at least neutral to alkaline, providing an alkaline cleaning composition. The alkaline cleaning composition does not contain an acid or acidulant, for example, a phosphorus-containing acid. As a result, the long-chain polyamines in the alkaline cleaning composition are not neutralized amines, meaning they are not cationic polyamines.

[0055] Antifoaming surfactant The components of the cleaning composition may further include an antifoaming surfactant. Exemplary antifoaming surfactants include alkoxylated nonionic surfactants, polyoxypropylene-polyoxyethylene polymer compounds, and inverted polyoxypropylene-polyoxyethylene polymer compounds.

[0056] Suitable nonionic surfactants for use in the compositions of the present invention include alkoxylated surfactants. Suitable alkoxylated surfactants include EO / PO copolymers, capped EO / PO copolymers, alcohol alkoxylates, capped alcohol alkoxylates, mixtures thereof, and the like. Suitable alkoxylated surfactants for use as solvents include EO / PO block copolymers such as Pluronic and reverse Pluronic surfactants; alcohol alkoxylates such as Dehypon LS-54 (R-(EO)5(PO)4) and Dehypon LS-36 (R-(EO)3(PO)6); capped alcohol alkoxylates such as Plurafac LF221 and Tegoten EC11; mixtures thereof, and the like.

[0057] Block polyoxypropylene-polyoxyethylene polymer compounds based on propylene glycol, ethylene glycol, glycerol, trimethylolpropane, and ethylenediamine as initiator reactive hydrogen compounds. Examples of polymer compounds made from sequential propoxylation and ethoxylation of the initiator are commercially available under the trade names Pluronic® and Tetronic® from BASF Corp. Pluronic® compounds are bifunctional (two reactive hydrogens) compounds formed by condensing ethylene oxide with a hydrophobic base formed by the addition of propylene oxide to the two hydroxyl groups of propylene glycol. This hydrophobic portion of the molecule has a molecular weight of from about 1,000 to about 4,000. Ethylene oxide is then added so as to sandwich this hydrophobic material between hydrophilic groups and is controlled by length so as to constitute from about 10 wt% to about 80 wt% of the final molecule. Tetronic® compounds are tetrafunctional block copolymers derived from the sequential addition of propylene oxide and ethylene oxide to ethylenediamine. The molecular weight of the propylene oxide hydrotype ranges from about 500 to about 7,000; the hydrophilic ethylene oxide is added so as to constitute from about 10 wt% to about 80 wt% of the molecule.

[0058] Ethylene oxide is added to ethylene glycol to provide a hydrophilic substance of a specified molecular weight, and then propylene oxide is added to obtain a hydrophobic block on the outer side (ends) of the molecule, thereby being modified, essentially inverted, block polyoxypropylene - polyoxyethylene polymer compounds. The hydrophobic portion of the molecule has a molecular weight of from about 1,000 to about 3,100, and the central hydrophilic substance comprises from 10 wt% to about 80 wt% of the final molecule. These inverted Pluronics™ are manufactured by BASF Corporation under the trademark of Pluronic™ R surfactants.

For example, in some embodiments, there are few, or no, additional functional formulation components therein.

[0061] In other embodiments, additional functional components may be included in the cleaning composition. The functional components impart the desired properties and functionality to the composition. For the purposes of this application, the term "functional component" includes materials that provide beneficial properties in specific applications when dispersed or dissolved in a concentrated solution such as an application and / or an aqueous solution. Some specific examples of functional materials are considered in more detail below, but the specific materials considered are merely examples and a variety of other functional components may be used.

Additionally, without limiting the present invention, all recited ranges include the numbers defining the range and each integer within the defined range.

[0065] Nonionic surfactant Useful nonionic surfactants are generally characterized by the presence of an organic hydrophobic group and an organic hydrophilic group and are typically produced by the condensation of an organic aliphatic, alkyl aromatic, or polyoxyalkylene hydrophobic compound with a hydrophilic alkaline oxide moiety that is generally ethylene oxide or its polyhydration product, polyethylene glycol. Specifically, any hydrophobic compound having a hydroxyl, carboxyl, amino, or amide group having a reactive hydrogen atom can be condensed with ethylene oxide, or its polyhydration additive, or a mixture thereof such as propylene oxide to form a nonionic surfactant. The length of the hydrophilic polyoxyalkylene moiety condensed with any particular hydrophobic compound can be readily adjusted to produce a water-dispersible or water-soluble compound having a desired degree of balance between hydrophilic and hydrophobic properties. Useful nonionic surfactants include

[0066] Block polyoxypropylene-polyoxyethylene polymer compounds based on propylene glycol, ethylene glycol, glycerol, trimethylolpropane, and ethylenediamine as initiator reactive hydrogen compounds. Examples of polymer compounds made from the sequential propoxylation and ethoxylation of initiators are commercially available from BASF Corp. One class of compounds is bifunctional (two reactive hydrogens) compounds formed by condensing ethylene oxide with a hydrophobic base formed by the addition of propylene oxide to the two hydroxyl groups of propylene glycol. This hydrophobic portion of the molecule has a molecular weight of from about 1,000 to about 4,000. Ethylene oxide is then added so as to sandwich this hydrophobic material between hydrophilic groups and is controlled in length so as to constitute from about 10 wt% to about 80 wt% of the final molecule. Another class of compounds is trifunctional block copolymers obtained from the sequential addition of propylene oxide and ethylene oxide to ethylenediamine. The molecular weight of the propylene oxide hydrotype ranges from about 500 to about 7,000; the hydrophilic ethylene oxide is added so as to constitute from about 10 wt% to about 80 wt% of the molecule.

[0067] Condensation products of about 3 to about 50 moles of ethylene oxide with 1 mole of an alkylphenol in which the alkyl chain is of straight or branched chain configuration, or of single or double alkyl constitutive material and contains from about 8 to about 18 carbon atoms. The alkyl group may be represented, for example, by diisobutylene, di-amyl, polymerized propylene, iso-octyl, nonyl, and di-nonyl. These surfactants may be polyethylene, polypropylene, and polybutylene oxide condensates of alkylphenols. Examples of commercial compounds of this chemistry are marketed under the trade names Igepal® from Rhone-Poulenc and Triton® from Union Carbide.

[0068] A condensation product of 1 mole of a saturated or unsaturated straight-chain or branched-chain alcohol having from about 6 to about 24 carbon atoms and from about 3 to about 50 moles of ethylene oxide.

Examples of similar commercial surfactants are available under the trade names Lutensol™, Dehydol™ from BASF, Neodol™ from Shell Chemical Co., and Alfonic™ from Vista Chemical Co.

[0069] A condensation product of 1 mole of a saturated or unsaturated straight-chain or branched-chain carboxylic acid having from about 8 to about 18 carbon atoms and from about 6 to about 50 moles of ethylene oxide.

Examples of commercial compounds of this chemistry are commercially available under the trade names Disponil or Agnique from BASF, and Lipopeg™ from Lipo Chemicals, Inc.

[0070] In addition to ethoxylated carboxylic acids, generally referred to as polyethylene glycol esters, other alkanoic acid esters formed by the reaction of glycerides, glycerin, and polyhydric (saccharide or sorbitan / sorbitol) alcohols have uses herein for specialized embodiments, particularly for indirect food additive applications. All of these ester moieties have on their molecules one or more reactive hydrogen sites that can be subjected to further acylation or ethylene oxide (alkoxide) addition to control the hydrophilicity of these substances. Care must be taken when adding these fatty esters or acylated carbohydrates to the compositions of the present invention containing amylase and / or lipase enzymes, as there may be a potential for incompatibility.

[0071] Examples of nonionic low-foaming surfactants include the following. Ethylene oxide is added to ethylene glycol to provide a hydrophilic substance of a specified molecular weight; then propylene oxide is added to obtain a hydrophobic block on the outer side (ends) of the molecule, thereby modifying the compound from (1) which is essentially inverted. The hydrophobic portion of the molecule has a molecular weight of from about 1,000 to about 3,100, and the central hydrophilic substance comprises from 10% to about 80% by weight of the final molecule. These inverted Pluronics™ are manufactured by BASF Corporation under the trademark of Pluronic™ R surfactants. Similarly, Tetronic™ R surfactants are manufactured by BASF Corporation by the sequential addition of ethylene oxide and propylene oxide to ethylenediamine. The hydrophobic portion of the molecule has a molecular weight of from about 2,100 to about 6,700, and the central hydrophilic substance comprises from 10% to about 80% by weight of the final molecule.

[0072] Compounds modified by "capping" or "end-blocking" the terminal hydroxy group(s) (of the polyfunctional moiety) by reaction with hydrophobic small molecules such as propylene oxide, butylene oxide, benzyl chloride, and short-chain fatty acids, alcohols, or alkyl halides containing 1 to about 5 carbon atoms, and mixtures thereof, in order to reduce foaming. Reactants such as thionyl chloride which convert the terminal hydroxy group to a chloride group are also included. Such modification of the terminal hydroxy group can result in all-block, block-hetero, hetero-block, or all-hetero nonionic substances.

Any reducing saccharide containing 5 or 6 carbon atoms can be used, for example, glucose, galactose, and the galactosyl moiety can be replaced by a glucosyl moiety. (Optionally, the hydrophobic group is bonded at the 2-position, 3-position, 4-position, etc., thus resulting in glucose or galactose as opposed to glucoside or galactoside.) The saccharide bond can be, for example, between one position of an additional saccharide unit and the 2-position, 3-position, 4-position, and / or 6-position on the preceding saccharide unit.

[0084] Useful classes of nonionic surfactants include alkoxylated amines, or, most specifically, the class defined as alcohol alkoxylated / aminated / alkoxylated surfactants. These nonionic surfactants are at least partially of the general formula: R 20 --(PO) S N--(EO) t H, R 20 --(PO) S N--(EO) t H(EO) t H, and R 20 --N(EO) t H, which may be represented by the formula, wherein R 20 is an alkyl, alkenyl or other aliphatic group, or an alkyl-aryl group having 8 to 20, preferably 12 to 14 carbon atoms, EO is oxyethylene, PO is oxypropylene, s is 1 to 20, preferably 2 to 5, t is 1 to 10, preferably 2 to 5, and u is 1 to 10, preferably 2 to 5.

[0085] The paper Nonionic Surfactants, Vol. 1 of the Surfactant Science Series, edited by Schick, M. J., Marcel Dekker, Inc., New York, 1983 is an excellent reference regarding the broad range of nonionic compounds commonly used in the practice of the present invention. The nonionic class and a typical list of these surfactant species are described in U.S. Patent No. 3,929,678, issued to Laughlin and Heuring on December 30, 1975. Further examples are described in "Surface Active Agents and detergents" (Volumes I and II, Schwartz, Perry and Berch).

[0086] Semi-polar nonionic surfactants Semi-polar types of nonionic surfactants are another class of nonionic surfactants useful in the compositions of the present invention. Generally, semi-polar nonionic substances are high-foaming substances and foam stabilizers, which may limit their application in CIP systems. However, in the compositional embodiments of the present invention designed for high-foaming cleaning methods, semi-polar nonionic substances have immediate practicality. Semi-polar nonionic surfactants include amine oxides, phosphine oxides, sulfoxides, and their alkoxylated derivatives.

[0087] The amine oxide is a tertiary amine oxide corresponding to the general formula, [Chemical formula] wherein the arrow is the conventional representation of a semi-polar bond, and R 1 , R 2 , and R 3 can be aliphatic, aromatic, heterocyclic, alicyclic, or a combination thereof. Generally, in detergent-related amine oxides, R 1 is an alkyl radical having about 8 to about 24 carbon atoms, R 2 and R 3 are alkyl or hydroxyalkyl having 1 to 3 carbon atoms, or a mixture thereof, R 2 and R 3 can be bonded to each other via, for example, an oxygen or nitrogen atom to form a ring structure, R 4 is an alkali or a hydroxyalkylene group containing 2 to 3 carbon atoms, and n ranges from 0 to about 20.

[0088] Useful water-soluble amine oxide surfactants are selected from coconut or tallow alkyldi-(lower alkyl) amine oxides, and specific examples thereof are dodecyldimethylamine oxide, tridecyldimethylamine oxide, tetradecyldimethylamine oxide, pentadecyldimethylamine oxide, hexadecyldimethylamine oxide, heptadecyldimethylamine oxide, octadecyldimethylamine oxide, dodecyldipropylamine oxide, tetradecyldipropylamine oxide, hexadecyldipropylamine oxide, tetradecyldibutylamine oxide, octadecyldibutylamine oxide, bis(2-hydroxyethyl)dodecylamine oxide, bis(2-hydroxyethyl)-3-dodecyloxy-1-hydroxypropylamine oxide, dimethyl-(2-hydroxydodecyl)amine oxide, 3,6,9-trioctadecyldimethylamine oxide, and 3-dodecyloxy-2-hydroxypropyl di-(2-hydroxyethyl)amine oxide.

[0089] Useful semi-polar non-ionic surfactants also include water-soluble phosphine oxides having the following structure, [Chemical formula] wherein the arrow is the conventional representation of a semi-polar bond, and R 1 is an alkyl, alkenyl, or hydroxyalkyl moiety in the chain length range of 10 to about 24 carbon atoms, and R 2 and R 3 are each an alkyl moiety separately selected from alkyl or hydroxyalkyl groups containing 1 to 3 carbon atoms.

[0090] Examples of useful phosphine oxides include dimethyldecylphosphine oxide, dimethyltetradecylphosphine oxide, methylethyltetradecylphosphine oxide, dimethylhexadecylphosphine oxide, diethyl-2-hydroxyoctyldecylphosphine oxide, bis(2-hydroxyethyl)dodecylphosphine oxide, and bis(hydroxymethyl)tetradecylphosphine oxide.

[0092] Useful examples of these sulfoxides include dodecylmethyl sulfoxide; 3-hydroxytridecylmethyl sulfoxide; 3-methoxytridecylmethyl sulfoxide; and 3-hydroxy-4-dodecyloxybutylmethyl sulfoxide.

[0093] The semi-polar nonionic surfactant for the composition of the present invention includes dimethylamine oxide such as lauryldimethylamine oxide, myristyldimethylamine oxide, cetyl dimethylamine oxide, and combinations thereof. Useful water-soluble amine oxide surfactants are selected from octyl, decyl, dodecyl, isododecyl, coconut, or tallow alkyldi-(lower alkyl)amine oxides, and specific examples thereof are octyldimethylamine oxide, nonyldimethylamine oxide, decyldimethylamine oxide, undecyldimethylamine oxide, dodecyldimethylamine oxide, isododecyldimethylamine oxide, tridecyldimethylamine oxide, tetradecyldimethylamine oxide, pentadecyldimethylamine oxide, hexadecyldimethylamine oxide, heptadecyldimethylamine oxide, octadecyldimethylamine oxide, dodecyldipropylamine oxide, tetradecyldipropylamine oxide, hexadecyldipropylamine oxide, tetradecyldibutylamine oxide, octadecyldibutylamine oxide, bis(2-hydroxyethyl)dodecylamine oxide, bis(2-hydroxyethyl)-3-dodecyloxy-1-hydroxypropylamine oxide, dimethyl-(2-hydroxydodecyl)amine oxide, 3,6,9-trioctadecyldimethylamine oxide, and 3-dodecyloxy-2-hydroxypropyl di-(2-hydroxyethyl)amine oxide.

[0094] Nonionic surfactants suitable for use in the compositions of the present invention include alkoxylated surfactants. Suitable alkoxylated surfactants include EO / PO copolymers, capped EO / PO copolymers, alcohol alkoxylates, capped alcohol alkoxylates, mixtures thereof, and the like. Alkoxylated surfactants suitable for use as solvents include EO / PO block copolymers such as Pluronic and reverse Pluronic surfactants; alcohol alkoxylates such as Dehypon LS-54 (R-(EO)5(PO)4) and Dehypon LS-36 (R-(EO)3(PO)6); capped alcohol alkoxylates such as Plurafac LF221 and Tegoten EC11; mixtures thereof, and the like.

[0095] Anionic surfactant Surfactants classified as anionic substances because the charge of the hydrophobic substance is negative, or surfactants in which the hydrophobic part of the molecule has no charge unless the pH rises above neutral (e.g., carboxylic acids) are also useful in the present invention. Carboxylates, sulfonates, sulfates, and phosphates are polar (hydrophilic) solubilizing groups found in anionic surfactants. Among the cations (counterions) associated with these polar groups, sodium, lithium, and potassium impart water solubility, ammonium and substituted ammonium ions provide both water solubility and oil solubility, and calcium, barium, and magnesium promote oil solubility. As will be understood by those skilled in the art, anionic substances are excellent detergent surfactants and are therefore preferred additives to heavy-duty detergent compositions.

[0096] Suitable anionic sulfate surfactants for use in the present composition include alkyl ether sulfates, alkyl sulfates, linear and branched primary and secondary alkyl sulfates, alkyl ethoxysulfates, fatty oleyl glycerol sulfates, alkylphenol ethylene oxide ether sulfates, C5-C 17Examples include sulfates of acyl-N-(C1-C4 alkyl) and -N-(C1-C2 hydroxyalkyl) glucamine, and sulfates of alkyl polysaccharides such as sulfates of alkyl polyglucosides. Also included are alkyl sulfates, alkyl poly(ethyleneoxy) ether sulfates, and aromatic poly(ethyleneoxy) sulfates such as sulfates of ethylene oxide and nonylphenol or concentrated products (usually having 1 to 6 oxyethylene groups per molecule).

[0097] Also suitable as an anionic sulfonate surfactant for use in the present composition are alkyl sulfonates, linear and branched primary and secondary alkyl sulfonates, and aromatic sulfonates with or without substituents.

[0098] Suitable anionic carboxylate surfactants for use in the present composition include carboxylic acids (and salts), such as alkanoic acids (and alkanoates), ester carboxylic acids (such as alkyl succinates), ether carboxylic acids, sulfonated fatty acids, such as sulfonated oleic acid, and the like. Such carboxylates include alkyl ethoxy carboxylates, alkyl aryl ethoxy carboxylates, alkyl polyethoxy polycarboxylate surfactants, and soaps (such as alkyl carboxyls). Secondary carboxylates useful in the present composition include those containing a carboxyl unit connected to a secondary carbon. The secondary carbon may be in a ring structure, such as in p - octylbenzoic acid or in alkyl - substituted cyclohexyl carboxylates. Secondary carboxylate surfactants typically do not contain ether bonds, ester bonds, and hydroxyl groups. Further, they typically lack a nitrogen atom within the head group (amphiphilic moiety). Suitable secondary soap surfactants typically contain 11 to 13 total carbon atoms, although more carbon atoms (e.g., up to 16) may be present. Suitable carboxylates also include acyl amino acids (and salts) such as acyl glutamates, acyl peptides, sarcosinates (such as N - acyl sarcosinates), taurates (such as fatty acid amides of N - acyl taurates and methyl tauride), and the like.

[0099] Suitable anionic surfactants include alkyl or alkyl aryl ethoxy carboxylates of the following formula: R - O - (CH2CH2O) n (CH2) m -CO2X(3) wherein R is a C8 - C 22 alkyl group or

Chemical formula

[0100] In other embodiments, R is

Chemical formula

[0101] Such alkyl and alkylaryl ethoxycarboxylates are commercially available. These ethoxycarboxylates are typically available in acid form and can be easily converted to anionic or salt form. Commercially available carboxylates include Neodox 23 - 4, C 12~13 alkyl polyethoxy(4) carboxylic acid (Shell Chemical), and Emcol CNP - 110, C9 alkylaryl polyethoxy(10) carboxylic acid (Witco Chemical). Carboxylates such as the product Sandopan® DTC, C 13 alkyl polyethoxy(7) carboxylic acid are also available from Clariant.

[0102] Cationic surfactant Surfactants are classified as cationic when the charge on the hydrotrope portion of the molecule is positive. Surfactants where the hydrotrope does not carry a charge unless the pH is near neutral or lowered below, and then becomes cationic (e.g., alkylamines), are also included in this group. Theoretically, cationic surfactants can be synthesized from any combination of elements containing the "onium" structure RnX+Y-- and can include compounds other than nitrogen (ammonium), such as phosphorus (phosphonium) and sulfur (sulfonium). In practice, the field of cationic surfactants is probably dominated by nitrogen-containing compounds because the synthetic routes to nitrogen cationic surfactants are simple and easy, yielding high-yield products, which makes nitrogen cationic surfactants less expensive.

[0103] Cationic surfactants preferably refer to compounds containing at least one long carbon chain hydrophobic group and at least one positively charged nitrogen. The long carbon chain group may be directly bonded to the nitrogen atom by simple substitution, or more preferably, indirectly bonded by the so-called crosslinking functional group(s) in interrupted alkylamines and amidoamines. Such functional groups can make the molecule more hydrophilic and / or more water-dispersible, more easily dissolved in water by a co-surfactant mixture, and / or water-soluble. For increased water solubility, additional primary, secondary, or tertiary amino groups can be introduced, or the amino nitrogen can be quaternized with low molecular weight alkyl groups. Further, the nitrogen can be part of a branched or straight-chain portion of various degrees of unsaturation, or part of a saturated or unsaturated heterocyclic ring. In addition, cationic surfactants may contain complex linkages with two or more cationic nitrogen atoms.

[0104] Surfactant compounds classified as amine oxides, amphoterics, and zwitterions are generally themselves cationic in solutions of near-neutral to acidic pH and overlap with the surfactant classification. Polyoxyethylated cationic surfactants generally behave like nonionic surfactants in alkaline solutions and like cationic surfactants in acidic solutions.

[0105] Most of the large number of commercial cationic surfactants can be subdivided into four main classes and additional subgroups known to those skilled in the art and are described in “Surfactant Encyclopedia”, Cosmetics&Toiletries, Vol.104(2)86-96(1989). The first class includes alkylamines and their salts. The second class includes alkylimidazolines. The third class includes ethoxylated amines. The fourth class includes quaternary substances such as, for example, alkylbenzyldimethylammonium salts, alkylbenzene salts, heterocyclic ammonium salts, tetraalkylammonium salts, etc. Cationic surfactants are known to have a variety of properties that can be beneficial in the present compositions. These desirable properties can include detergency in compositions of pH below neutral, antimicrobial efficacy, thickening or gelling in conjunction with other agents, etc.

[0106] Useful cationic surfactants in the compositions of the present invention include those having the formula R 1 m R 2 x Y L Z, wherein each R 1 contains a straight-chain or branched alkyl or alkenyl group, optionally substituted with up to 3 phenyl or hydroxy groups, and up to 4 of the following structures:

Chemical formula

[0107] Amphoteric surfactant Amphoteric or ampholytic surfactants contain both basic and acidic hydrophilic groups, as well as organic hydrophobic groups. These ionic entities can be either anionic or cationic groups as described herein for other types of surfactants. Basic nitrogen and acidic carboxylate groups are typical functional groups used as basic and acidic hydrophilic groups. In some surfactants, sulfonate, sulfate, phosphonate, or phosphate provides a negative charge.

[0108] Amphoteric surfactants can be broadly described as derivatives of aliphatic secondary and tertiary amines, where the aliphatic radical may be straight-chain or branched, and one of the aliphatic substituents contains from about 8 to 18 carbon atoms and one contains an anionic hydrotropic group such as carboxy, sulfo, sulfato, phosphato, or phosphono. Amphoteric surfactants are known to those skilled in the art and are subdivided into two main classes described in "Surfactant Encyclopedia" Cosmetics&Toiletries, Vol. 104(2) 69-71(1989), which is hereby incorporated by reference in its entirety. The first class includes acyl / dialkylethylenediamine derivatives (e.g., 2-alkylhydroxyethylimidazoline derivatives) and their salts. The second class includes N-alkylamino acids and their salts. Some amphoteric surfactants may be assumed to fit into both classes.

[0109] Amphoteric surfactants can be synthesized by methods known to those skilled in the art. For example, 2-alkylhydroxyethylimidazoline is synthesized by the condensation and ring closure of a long-chain carboxylic acid (or derivative) with dialkylethylenediamine. Commercially available amphoteric surfactants are derivatized, for example, with chloroacetic acid or ethyl acetate, by subsequent hydrolysis and ring opening of the imidazoline ring by alkylation. During alkylation, one or two carboxy-alkyl groups react to form a tertiary amine and an ether bond, and different alkylating agents yield different tertiary amines.

[0110] The long-chain imidazole derivatives having uses in the present invention generally have the following general formula:

Chemical formula

[0111] The above carboxymethylated compound (glycinate) in this specification is often called betaine. Betaine is a special class of amphoteric compounds described below in this specification in the section entitled zwitterionic surfactants.

[0112] Long-chain N-alkyl amino acids are easily prepared by the reaction RNH2, where R = C8-C 18 are aliphatic amines with straight-chain or branched-chain alkyl, halogenated carboxylic acids. Alkylation of the primary amino group of the amino acid results in secondary and tertiary amines. The alkyl substituent may have additional amino groups that provide multiple reactive nitrogen centers. The most commercially available N-alkyl amino acids are alkyl derivatives of β-alanine or β-N(2-carboxyethyl)alanine. Examples of commercially available N-alkyl amino acid ampholytes applicable to the present invention include alkyl β-aminodipropionate, RN(C2H4COOM)2 and RNHC2H4COOM. In one embodiment, R can be an acyclic hydrophobic group containing about 8 to about 18 carbon atoms, and M is a cation for neutralizing the charge of the anion.

[0113] Suitable amphoteric surfactants include those derived from coconut products such as coconut oil or coconut fatty acids. Additional preferred coconut-derived surfactants include, as part of these structures, an ethylenediamine moiety, an alkanolamide moiety, an amino acid moiety, such as glycine, or combinations thereof, and an aliphatic substituent of about 8 to 18 (e.g., 12) carbon atoms. Such surfactants may also be regarded as alkyl amphodicarboxylic acids. These amphoteric surfactants have the chemical structure represented as C 12 -alkyl-C(O)-NH-CH2-CH2-N + (CH2-CH2-CO2Na)2-CH2-CH2-OH or C 12 -alkyl-C(O)-N(H)-CH2-CH2-N + (CH2-CO2Na)2-CH2-CH2-OH. Disodium cocoamphodipropionate is one suitable amphoteric surfactant and is commercially available under the trade name Miranol™ FBS from Rhodia Inc., Cranbury, N.J. Another suitable coconut-derived amphoteric surfactant having the chemical name disodium cocoamphodiacetate is also sold under the trade name Mirataine™ JCHA from Rhodia Inc., Cranbury, N.J.

[0114] A typical listing of the amphoteric class and species of these surfactants is described in U.S. Patent No. 3,929,678 issued to Laughlin and Heuring on December 30, 1975. Further examples are described in “Surface Active Agents and Detergents” (Vol. I and II by Schwartz, Perry and Berch). Each of these references is hereby incorporated by reference in its entirety.

[0115] zwitterionic surfactant zwitterionic surfactants can be considered a subset of amphoteric surfactants and may contain anionic charges. Zwitterionic surfactants can be broadly described as derivatives of secondary and tertiary amines, derivatives of heterocyclic secondary and tertiary amines, or derivatives of quaternary ammonium, quaternary phosphonium, or tertiary sulfonium compounds. Typically, zwitterionic surfactants contain a positively charged quaternary ammonium, or in some cases sulfonium or phosphonium ion, a negatively charged carboxyl group, and an alkyl group. Zwitterionic compounds generally contain cationic and anionic groups that are ionized to approximately the same extent in the isoelectric region of the molecule and can produce a strong "internal salt" attraction between the positive and negative charge centers. Examples of such zwitterionic synthetic surfactants include derivatives of aliphatic quaternary ammonium, phosphonium, and sulfonium compounds, where the aliphatic group can be straight-chain or branched, one of the aliphatic substituents contains 8 to 18 carbon atoms, and one contains an anionic solubilizing group, such as carboxy, sulfonate, sulfate, phosphate, or phosphonate.

[0116] Betaine and sultaine surfactants are examples of zwitterionic surfactants for use herein. The general formulas for these compounds are as follows:

Chemical formula

[0117] Examples of the zwitterionic surfactant having the above structure include 4-[N,N-bis(2-hydroxyethyl)-N-octadecylammonio]-butane-1-carboxylate, 5-[S-3-hydroxypropyl-S-hexadecylsulfonio]-3-hydroxypentane-1-sulfate, 3-[P,P-diethyl-P-3,6,9-trioxatetracosanephosphonio]-2-hydroxypropane-1-phosphate, 3-[N,N-dipropyl-N-3-dodecoxy-2-hydroxypropyl-ammonio]-propane-1-phosphonate, 3-(N,N-dimethyl-N-hexadecylammonio)-propane-1-sulfonate, 3-(N,N-dimethyl-N-hexadecylammonio)-2-hydroxy-propane-1-sulfonate, 4-[N,N-bis(2(2-hydroxyethyl)-N(2-hydroxydodecyl)ammonio]-butane-1-carboxylate, 3-[S-ethyl-S-(3-dodecoxy-2-hydroxypropyl) sulfonio]-propane-1-phosphate, 3-[P,P-dimethyl-P-dodecylphosphonio]-propane-1-phosphonate, and S[N,N-bis(3-hydroxypropyl)-N-hexadecylammonio]-2-hydroxy-pentane-1-sulfate. The alkyl group contained in the detergent surfactant may be linear or branched and may be saturated or unsaturated.

[0118] The zwitterionic surfactants suitable for use in the present composition include betaines having the following general structure. [Chemical formula] These surfactant betaines typically do not exhibit strong cationic or anionic characteristics at extreme pHs or do not show a decrease in water solubility within their isoelectric ranges. Unlike "external" quaternary ammonium salts, betaines can coexist with anions. Examples of suitable betaines include coconut acylamidopropyldimethylbetaine, hexadecyldimethylbetaine, C 12-14 acylamidopropylbetaine, C 8-14 acylamidohexyldiethylbetaine, 4-C 14-16 acylmethylamidodiethylammonio-1-carboxybutane, C 16-18 acylamidodimethylbetaine, C 12-16 acylamidopentanediethylbetaine, and C 12-16 acylmethylamidodimethylbetaine.

[0119] The sultaines useful in the present invention include compounds having the formula (R(R 1 )2N + R 2 SO 3- , where R is a C6 - C 18 hydrocarbyl group, each R 1 is typically independently a C1 - C3 alkyl, such as methyl, and R 2 is a C1 - C6 hydrocarbyl group, such as a C1 - C3 alkylene or hydroxyalkylene group.

[0120] A typical list of zwitterionic classes and species of these surfactants is described in U.S. Patent No. 3,929,678 issued to Laughlin and Heuring on December 30, 1975. Further examples are described in "Surface Active Agents and Detergents" (Vol.I and II by Schwartz, Perry and Berch). Each of these references is incorporated herein by reference in its entirety.

[0121] Antifoaming agent The compositions and methods of the present invention may optionally include an antifoaming agent. The antifoaming agent may be particularly suitable for embodiments that include a foaming surfactant such as an anionic surfactant. Generally, antifoaming agents that may be used include silica and silicone, fatty acids or esters, alcohols, sulfates or sulfonates, amines or amides, halogen compounds such as fluorochlorohydrocarbons, vegetable oils, waxes, mineral oils, and their sulfonated or sulfated derivatives, alkalis, fatty acids such as alkaline earth metal soaps and / or their soaps, and phosphates and phosphate esters such as alkyl and alkaline diphosphates and especially tributyl phosphate, and mixtures thereof.

[0122] In some embodiments, the composition may include an antifoaming agent or defoaming agent that is of food-grade quality, considering the applications of the methods of the present invention. For this purpose, silicone is included among the more effective antifoaming agents. Silicones such as dimethyl silicone, glycol polysiloxane, methylphenyl polysiloxane, trialkyl or tetraalkyl silane, hydrophobic silica antifoaming agent, and mixtures thereof can all be used for defoaming purposes. Commercially available antifoaming agents that are generally available include, among others, ARDEFOAM (trademark) manufactured by Armour Industrial Chemical Company, which is silicone bound in an organic emulsion; FOAM KILL (trademark) or KRESSEO (trademark) available from Krusable Chemical Company, which are silicone and non-silicone type antifoaming agents and silicone esters; and silicones such as ANTI-FOAM A (trademark) and DC-200 manufactured by Dow Corning Corporation, both of which are food-grade type silicones.

[0123] Enzyme In some embodiments, the composition may further include an enzyme. Preferably, in a cleaning composition that does not contain an alkali source, the enzyme and water constitute the majority of the cleaning composition.

[0124] Since enzymes are proteins, it is important that the other components of the composition do not denature the enzyme and thus render it ineffective for its intended purpose. For preferred cleaning compositions incorporating active enzymes or enzymes stabilized by other means, the pH of the composition is important. That is, the pH of the composition containing the enzyme must be such that the enzyme component remains stable and does not denature. Such a pH can be approximately neutral or near neutral, or about 7 - 8.

[0125] Amylase is an example of an enzyme useful in cleaning compositions. Examples of amylases that can be used are alpha - amylases from Bacillus licheniformis, B. amyloliquiefaciens, or B. stearothermophilus, as well as developed products thereof improved for use in detergents and cleaning compositions. Novozymes and Genencor market commercially available alpha - amylases derived from one or all of the above bacterial species. Novozymes further offers alpha - amylases derived from Aspergillus niger and A. oryzae.

[0126] Protease is an example of an enzyme useful in cleaning compositions. Proteases can be derived from microorganisms such as yeast, mold, or bacteria. An example of a proteolytic enzyme that can be used in a cleaning composition is Savinase. Proteases from Bacillus lentus, Bacillus licheniformis, Bacillus amyloliquefaciens, Bacillus alcalophilus are commercially available from Genencor International, Solvay Enzymes, Novozymes, etc.

[0127] Preferred enzymes provide good protein removal and cleaning performance, leave no residues, are easily formulated and form stable products. For example, Savinase, commercially available from Novozymes, is a serine-type endoprotease and has activity in the pH range of 8 - 12 and the temperature range of 20°C - 60°C. As a further example, Alcalase, commercially available from Novozymes, is derived from Bacillus licheniformis and has activity in the pH range of 6.5 - 8.5 and the temperature range of 45°C - 65°C. Esperase is commercially available from Novozymes, is derived from Bacillus species, and has an alkaline pH activity range and a temperature range of 50°C - 85°C.

[0128] Mixtures of different enzymes can be incorporated into the cleaning composition. While various specific enzymes are described above, it is understood that any protease that can impart the desired proteolytic activity to the composition can be used. The compositions of the present invention contain from about 0 wt% to about 25 wt% enzyme, from about 0.0005 wt% to about 15 wt% enzyme, from about 0.001 wt% to about 10 wt% enzyme, from about 0.001 wt% to about 5 wt% enzyme, from about 0.001 wt% to about 1 wt% enzyme. Additionally, without limiting the scope of the present invention, all ranges recited include the numbers defining the range and include each integer within the defined range.

[0129] Chelating agent In some embodiments, the composition may further comprise a chelating agent. As used herein, chelation means the binding or complex formation of a bidentate or multidentate ligand. These ligands are often organic compounds and are referred to as chelants, chelators, chelating agents, and / or sequestering agents. A chelating agent forms multiple bonds with a single metal ion. A chelating agent is a chemical substance that forms soluble complex molecules with specific metal ions, inactivating those ions so that they cannot normally react with other elements or ions to form precipitates or scales. The ligand forms a chelate complex with the substrate. The term is for complexes in which a metal ion is bound to two or more atoms of the chelating agent.

[0130] Suitable aminocarboxylic acid type chelating agents include the acid or its alkali metal salts. Some examples of aminocarboxylic acid materials include aminoacetate and its salts. Some examples include the following: N-hydroxyethyliminodiacetic acid, hydroxyethylenediaminetetraacetic acid, nitrilotriacetic acid (NTA), ethylenediaminetetraacetic acid (EDTA), N-hydroxyethyl-ethylenediaminetriacetic acid (HEDTA), diethylenetriaminepentaacetic acid (DTPA), and alanine-N,N-diacetic acid, etc., as well as mixtures thereof. Particularly useful aminocarboxylic acid materials that contain little or no NTA and no phosphorus include N-hydroxyethyliminodiacetic acid, ethylenediaminetetraacetic acid (EDTA), hydroxyethylenediaminetetraacetic acid, diethylenetriaminepentaacetic acid, N-hydroxyethyl-ethylenediaminetriacetic acid (HEDTA), diethylenetriaminepentaacetic acid (DTPA), methylglycine diacetic acid (MGDA), aspartic acid-N,N-diacetic acid (ASDA), glutamic acid-N,N-diacetic acid (GLDA), ethylenediamine succinic acid (EDDS), 2-hydroxyethyliminodiacetic acid (HEIDA), iminodisuccinic acid (IDS), 3-hydroxy-2,2'-iminodisuccinic acid (HIDS), and other similar acids having an amino group together with a carboxylic acid substituent.

Suitable chelating agents include aminocarboxylates, aminophosphonates, polyfunctional substituted aromatic chelating agents, and mixtures thereof. Exemplary chelating agents include amino acid-based chelating agents, and preferably citric acid, tartaric acid, and glutamic acid-N,N-diacetic acid and derivatives, and / or phosphonate-based chelating agents.

[0132] Examples of other chelating agents include homopolymers and copolymers of polycarboxylic acids and their partially or fully neutralized salts, and monomeric polycarboxylic acids and hydroxycarboxylic acids and their salts. Preferred salts of the above compounds are ammonium and / or alkali metal salts, i.e., lithium, sodium, and potassium salts, and particularly preferred salts are sodium salts such as sodium sulfate.

[0133] Other chelating agents include polycarboxylic acid polymers. Representative polycarboxylic acid polymers suitable for the rinsing composition include, among others, aminocarboxylic acids, water-soluble acrylic polymers, polymaleic acid homopolymers, and maleic acid polymers, and the rinsing solution is adjusted under the final use conditions. Such polymers include polyacrylic acid, polymethacrylic acid, acrylic acid-methacrylic acid copolymers, hydrolyzed polyacrylamide, hydrolyzed methacrylamide, hydrolyzed acrylamide-methacrylamide copolymers, hydrolyzed polyacrylonitrile, hydrolyzed polymethacrylonitrile, hydrolyzed acrylonitrile methacrylonitrile copolymers, or mixtures thereof. Water-soluble salts or partial salts of these polymers, such as their respective alkali metals (e.g., sodium or potassium), or ammonium salts, can also be used.

[0134] In addition, phosphonates or phosphonic acid metal ion sequestering agents can also be used. In some embodiments, the phosphonate and / or phosphonic acid metal ion sequestering agent can be used alone without a polycarboxylic acid polymer. Such useful phosphonic acids include mono-, di-, tri-, and tetraphosphonic acids, which can also contain groups capable of forming anions under alkaline conditions such as carboxy, hydroxy, thio, etc.

[0135] Water quality conditioning polymer In one embodiment, the composition optionally includes a water conditioning polymer(s). In some aspects, the water conditioning polymer is a secondary builder or a scale inhibitor of the composition. According to one embodiment, the water conditioning polymer can be a non-phosphorus polymer. In one aspect, the water conditioning polymer is a non-ionic surfactant. In one aspect, the water conditioning polymer is a polycarboxylic acid and / or a hydrophobically modified polycarboxylic acid. An exemplary polyacrylic acid is commercially available as Acusol® 445N (Dow Chemical). In a further embodiment, a neutralized polycarboxylic acid polymer is used as the water conditioning polymer. An exemplary neutralized polycarboxylic acid is commercially available as Acumer® 1000 (Rohm & Haas Company).

[0136] In a further aspect, the water conditioning polymer can include a polycarboxylate or a related copolymer. Polycarboxylate refers to a compound having a plurality of carboxylate groups. Various such polycarboxylate polymers, and copolymers are known, described in patents and other literature, and are commercially available. Exemplary polycarboxylates that can be used as a builder and / or a water conditioning polymer include acrylic homopolymers, polyacrylic acid, maleic acid, maleic acid / olefin copolymers, sulfonated copolymers or terpolymers, acrylic / maleic acid copolymers, polymethacrylic acid, acrylic acid-methacrylic acid copolymers, hydrolyzed polyacrylamide, hydrolyzed polymethacrylamide, hydrolyzed polyamide-methacrylamide copolymers, hydrolyzed polyacrylonitrile, hydrolyzed polymethacrylonitrile, and hydrolyzed acrylonitrile-methacrylonitrile copolymers, such as pendant carboxylates (-CO2 -)Those having a base are included, but not limited thereto.

[0139] Washing method The cleaning method is particularly suitable for removing lip cosmetic stains. Although it is not desirable to be constrained by scientific theories, the hydrophobic part of the lip cosmetic stain is considered to particularly make it difficult to remove the stain from the utensils. The hydrophobic part of the lip cosmetic can be oil, a viscous solid, or wax, depending on the desired consistency of the final product. For example, lip gloss rolled on the lips tends to be more liquid in consistency than lip gloss applied using fingertips. Naturally, roll-on lip gloss is expected to have a higher oil content and a larger amount of solids and waxes than fingertip lip gloss. The hydrophobic components of lip cosmetics can be natural or synthetic.The following is a non-limiting list of hydrophobic materials found in lip cosmetics: wax from the skin of Pyrus Malus, Persea Gratissima wax, Myrica cerifera wax, beeswax, Euphorbia cerifera wax, canola oil, Copernicia cerifera wax, castor oil, ceresin, cetyl alcohol, cetyl esters, Theobroma cacao butter, Cocos nucifera oil, hydrogenated jojoba oil, hydrogenated jojoba wax, hydrogenated microcrystalline wax, hydrogenated rice bran wax, hydrolyzed beeswax, isostearic acid, jojoba butter, jojoba esters, jojoba wax, lanolin oil, lanolin wax, microcrystalline wax, mineral oil, mink wax, montanic acid wax, montan wax, Olea europaea oil, Citrus aurantium dulcis peel wax, ouricury wax, oxidized beeswax, oxidized microcrystalline wax, ozokerite, palm kernel wax, paraffin, PEG-6 wax, PEG-8 wax, PEG-12 wax, PEG-20 wax, PEG-12 carnauba, petrolatum, petrolatum, potassium oxidized microcrystalline wax, Oryza sativa wax, Sesamum indicum oil, Butyrospermum parkii, shellac wax, used cereal wax, stearic acid, sulfurized jojoba oil, synthetic beeswax, synthetic candelilla wax, synthetic carnauba, synthetic Japan wax, synthetic jojoba oil, synthetic wax, and vegetable oils. Additional materials found in lip cosmetics include silicones such as dimethicone, along with other pigments, dyes, colorants, and fragrances.

[0140] The compositions disclosed herein are believed to be able to remove lip cosmetic stains having the above hydrophobic and other materials as well as those not included in the above list.

[0141] The method is particularly suitable for removing lip cosmetic stains that accumulate on the surface of drinking utensils, which are typical of any type of utensils found in any commercial, organizational, or consumer location, including restaurants, bars, hospitals, nursing homes, domestic (consumer) residences, aviation facilities, schools, and corporate cafeterias.

[0142] The cleaning method includes contacting an article or other hard surface that needs to have lip cosmetic stains removed, such as lipstick, lip stain, lip gloss, lip balm, and / or lip cream. In one aspect, the article or hard surface is soiled with waxy, oily, and / or fatty stains. For example, any contacting means, including dipping, spraying, dripping, wiping, etc., can be used to contact the article or hard surface with an alkaline cleaning composition. Included within the scope of the contact described herein, the article and / or hard surface may also include a pretreatment and may be immersed in the alkaline composition. As a result of the contacting step, the surface is cleaned and the stains are removed.

[0143] In certain embodiments, a concentrate can be sprayed onto the surface for hard surface treatment. The contact time can vary from several seconds to several minutes. In other embodiments, a lower concentration of the cleaning composition can be used for pre-soaking, such as when an article or silverware is soaked before being placed in a dishwashing machine. In such embodiments, the contact time can vary from several minutes to several hours (e.g., overnight soaking).

[0144] In one aspect, the surface is an article. Exemplary articles include, for example, glass, ceramics, melamine, and / or plastic. The article cleaning described herein can be done manually. In another aspect, the article is cleaned in a dishwashing machine.

[0145] In both the use for cleaning utensils, the use for immersion (or pretreatment), and / or other uses for treating hard surfaces, a long-chain polyamine can be added to the alkaline composition in the use solution. Alternatively, a fully formulated alkaline cleaning composition can be provided. A first step of diluting and / or preparing an aqueous use solution (such as from a solid) can also be included in the method. An exemplary dilution step includes contacting a liquid and / or solid composition with water.

[0146] The alkaline cleaning composition can be provided at the desired amount of the surfactant of the components of the composition and / or at the surfactant level in a ready-to-use and / or concentrated composition. In one aspect, the long-chain polyamine is provided at a concentration of about 10 ppm to about 200 ppm in the use solution, or about 100 ppm to about 200 ppm in the use solution.

[0147] In one aspect, the alkaline cleaning composition contacts utensils and / or other hard surfaces that require cleaning with the use solution and has a pH of about 7.5 to about 13.5.

[0148] In one aspect, the alkaline cleaning composition contacts the utensils and / or other hard surfaces for a sufficient time, including from seconds to hours, including all ranges therebetween, to remove dirt. In one embodiment, the composition contacts the utensils and / or other hard surfaces for at least about 15 seconds, at least about 30 seconds, at least about 45 seconds, or at least about 60 seconds. In one embodiment, the composition contacts the utensils and / or other hard surfaces for at least about 1 minute, at least about 2 minutes, at least about 3 minutes, at least about 4 minutes, or at least about 5 minutes.

[0149] All publications and patent applications herein are indicative of the level of those skilled in the art to which the invention pertains. All publications and patent applications are incorporated herein by reference to the same extent as if each individual publication or patent application was specifically and individually incorporated by reference.

Chemical formula

Chemical formula

[0152] Example 1 A 1000 mL beaker was filled with 600 g of cold tap water at 5 gpg. 1000 ppm of Formula A and 100 ppm of long-chain polyamine were added and magnetically stirred at 200 RPM for at least 5 minutes for equilibration. Tables 1 and 2 detail the composition of each formulation. The experiments were conducted under ambient conditions.

Table 6

Table 7

[0153] On two new slide glasses, a line of lipstick was drawn along the length of the slide. Using binder clips, the two slides were suspended from stainless steel hooks facing each other. While stirring the solution at 200 RPM, the slides were immersed in the solution, keeping the slides as vertical as possible and not placing them in the vortex at the center of the beaker.

[0154] The slides were taken out, placed in the solution at ambient temperature for 16 hours, and then air-dried. Next, the performance of each formulation regarding the removal of lipstick pigments and waxes was visually evaluated.

[0155] As shown in FIGS. 1A - 1C, FIGS. 2A - 2C, and FIGS. 3A - 3C respectively, no removal of pigments or waxes was observed for the entire lipstick brands of Formulations A, D, and E. Each figure shows an image of the slide glass after treatment with the formulation.

[0156] Formulation B demonstrated complete pigment removal and partial wax removal for Covergirl 435 and Covergirl 305. For the MAC C46 sample, there was partial pigment and wax removal. The results of Formulation B are shown in FIGS. 4A - 4C.

[0157] Formulation C showed complete pigment removal and partial wax removal for the Covergirl 435 and Covergirl 305 samples. For the MAC C46 sample, there was some pigment removal and minimal wax removal. The results of Formulation C are shown in FIGS. 5A - 5C.

[0158] Example 2 An Ecolab low - temperature warewashing machine with a dish basket was filled with 1.5 gallons of 5 gpg water at 120°F. Pre - soiled lipstick tiles were placed on a stainless - steel tile holder fixed midway between the center and the rear left corner of a rack, attached with binder clips. The basket was then placed in the warewashing machine, and the appropriate formulation was added according to Table 3 and the cycle was run. The cycle was repeated a total of 50 or 5 cycles, and fresh chemicals were dosed in each cycle to keep the concentration constant. The warewashing machine maintained a water temperature of 120°F for washing and rinsing. Each test was repeated 2 or 3 times. After the test, digital images of the tiles were taken using a white background. The Fiji ImageJ software (an open - source image - processing package) was used to change the images to 16 - bit black - and - white images and the threshold was set to 215. Measurements were taken using ImageJ to determine the percent coverage on a predetermined area on the tile. [Table 8]

[0159] After the test, digital images of the tiles were taken using a white background. The Fiji ImageJ software (an open - source image - processing package) was used to change the images to 16 - bit black - and - white images and the threshold was set to 215. Measurements were taken using ImageJ to determine the percent coverage on a predetermined area on the tile.

[0160] The percentage of lipstick remaining after the test is shown in Figure 6. This is a graphical representation of the percentage of lipstick remaining in the evaluated formulations. The lower the value, the more the lipstick was removed. Advantageously, the evaluated formulations containing long-chain polyamines in the alkaline detergent composition provide effective removal of lip stains from articles.

[0161] Example 3 Normal drinking glass articles were visually inspected for scratches or residual dirt prior to use. These glasses selected for testing were stamped with Covergirl 435 using a lipstick stamp with the lipstick applied to a clean stainless steel specimen. The specimen or other clean end was dragged across the stamp in the direction of the raised portion of the stamp until the raised portion was completely coated in a visible state. The stamp was then pressed against the side of the glass midway between the base and the edge. While applying uniform pressure, gentle side-to-side rocking motion was used to ensure uniformity of the lipstick coating before removing the stamp from the glass surface. By using the lipstick stamp procedure, an industrially applicable dishwasher-compatible, repeatable, and consistent lipstick removal performance evaluation method is provided.

[0162] Images of each glass were taken inside a light box with a white background. A Nikon D5300 DSLR equipped with Camera Control Pro2 software was used at a shutter speed of 1 / 80 second and an aperture of f / 2.8. The glasses were then placed in the dishwasher basket at the front center, front center, center, center rear, and / or rear corner with the lipstick facing forward. The basket was then placed in a dishwashing machine filled with 1.5 gallons of 17 gpg water at 120°F. The appropriate formulations were added according to Table 4 and the cycle was run. The cycle was repeated for a total of 25 cycles and new chemicals were administered as needed to maintain a constant concentration. The dishwashing machine maintains a water temperature of 120°F for washing and rinsing.

Table 9

[0163] After the test was completed, the glass was removed from the basket, air-dried, and re-photographed in the light box using the same procedure as before the test. The amount of pigment / lipstick removed was measured using Fiji's ImageJ software. Each image was opened in ImageJ, the image type was changed to black and white under the Image tab, and the threshold value was adjusted to 152. A macro was used to ensure that the same area of exactly 553,152 square pixels was measured for each sample before and after the test.

[0164] The rectangle was adjusted to contain the stamped lipstick, and the area percentage measurement was recorded. The amount of pigment removed was calculated using the area percentage measurements before and after treatment. The percentage of lipstick removed at each basket position is shown in Figures 7 - 11.

[0165] Example 4 Additional tests for removing lipstick stains from the glass style were performed. The pre-stained pink lipstick on the glass style was obtained from Center for Test materials BV in the Netherlands. The test was completed in an ES2000 low-temperature machine using 5 gpg water. The fill volume was 1.5 gallons, and the influent water temperature was 120°F. The soiled tile was placed on a stainless-steel tile holder fixed at the middle of the rack and the rear left corner of the machine, attached with a binder clip. The appropriate formulation was added according to Table 5, and a complete wash and rinse cycle was executed. The cycle was repeated 50 times in total, and new chemicals were administered as needed to keep the concentration constant.

Table 10

[0166] After the test was completed, the glass tiles were removed from the basket, air-dried, and images were collected using a color scanner against a white background. The amount of removed pigment / lipstick was measured using Fiji's ImageJ software. Each image was opened in ImageJ, the image type was changed to black and white under the Image tab, and the threshold value was adjusted to 215. Macros were used to ensure that the same area was analyzed and measured for each sample. Figure 12 shows the results that compositions containing C6-C20 polyamines, i.e., long-chain polyamines, functioned equally well to remove lipstick stains regardless of the presence or absence of an alkali source.
