Description

Technical Field

[0001] Cross - reference to Related Applications This application claims priority under 35 U.S.C. § 119(e) to U.S. Provisional Application No. 62 / 595,686, filed on November 7, 2017, the entire disclosure of which is hereby incorporated by reference herein.

[0002] The present invention relates to a method for cleaning waxy, oily, and / or fatty soils, including lip makeup soils such as lipstick and lip gloss. In particular, the removal of lip makeup soils, including lipstick and lip gloss stains in laundry and other hard - surface cleaning applications, is disclosed through the application of a solid and / or liquid cleaning composition that contains a branched Poly amine, namely a C6 - C20, C8 - C20, C10 - C20, C10 - C18, or C10 - C12 branched Poly amine, with or without an alkali source and preferably an additional surfactant.

Background Art

[0003] Various fabric substrates, textiles, and laundry are often contaminated with lip makeup stains rubbed onto fabrics and laundry from people's lips. Lip makeup stains are typically very difficult to remove due to their waxy, oily, and / or greasy viscosity. Recently, as a result of advancements in the lip makeup industry, such as new "long-lasting" lipsticks, removing lip makeup stains has become even more difficult. In the past, such fabric substrates have undergone various pre-treatment and / or washing processes depending on the specific method used to attempt to remove such stubborn stains. Before a conventional washing cycle, pre-treatment or soaking was used to remove or loosen lip makeup stains at the end. Often, these pre-treatments required soaking the substrate in the cleaning composition to allow sufficient contact with the stain. Additional processes include, for example, re-washing the substrate, manually scrubbing the substrate, and / or adding extra time to the washing machine cycle to remove such stains. There is a need for improved stain removal methods for lip makeup. [Overview of the project] [Problems that the invention aims to solve]

[0004] Therefore, the objective is to develop improved solid and / or liquid cleaning compositions for effectively removing waxy, oily, and / or greasy stains, including lip makeup stains.

[0005] A further objective is to provide improved wash cycle performance for removing such lip makeup stains.

[0006] A further objective is to provide a cleaning composition that does not require the use of a pretreatment step for immersing lip makeup stains on a fabric substrate.

[0007] A further objective is to provide an efficient method for using such cleaning compositions.

[0008] Other objects, advantages, and features of the present invention will become apparent from the following specification in conjunction with the accompanying drawings. [Means for solving the problem]

[0009] The advantage of the composition and method is that the formulation containing multiple surfactants provides synergistic cleaning power against lip makeup stains in laundry applications. The solid and / or liquid alkaline cleaning composition is branched Poly Amines, i.e., C6-C20 atoms with 1-5 nitrogen atoms. Poly Amines, preferably C8-C20, C8-C18, or C10-C18 having 1-5 nitrogen atoms. Poly Examples include amines. The cleaning composition may contain or exclude an alkaline source. A preferred alkaline cleaning composition contains a surfactant and at least one branched Poly This includes hydroxide-based, carbonate-based, and / or silicate-based detergents containing amines.

[0010] In one embodiment, the laundry cleaning composition comprises an alkali source, which, if present, is an alkali metal hydroxide, alkali metal carbonate, alkali metal silicate, alkali metal metasilicate, and / or organic nitrogen base; at least a cleaning and / or defoaming surfactant; a water adjusting agent; an enzyme; an oxidizing agent; and / or a fluorescent whitening agent; and a branched C6-C20 polyamine.

[0011] In one embodiment, the alkaline laundry detergent composition comprises a C8-C20 branched polyamine, preferably a C9-C20 polyamine, a nonionic surfactant, and water.

[0012] In one embodiment, a method for removing waxy, oily, and / or greasy stains includes preparing a textile substrate having waxy, oily, and / or greasy stains, contacting the textile substrate with an alkaline cleaning composition as disclosed herein, and washing the textile substrate to remove the stains.

[0040] Cleaning compositions can be provided in liquid, solid, and / or emulsion form. Cleaning compositions may include concentrated solid and / or liquid compositions, or they may be diluted to form work-in-use compositions and ready-to-use compositions. Generally, a concentrate refers to a composition intended to be diluted with water to provide a work-in-use solution that comes into contact with an object to provide the desired cleaning, rinsing, etc. A cleaning composition that comes into contact with an article or product being cleaned may be referred to as a concentrate or a work-in-use composition (or work-in-use solution), depending on the formulation used in the method. It should be understood that the concentrations of long-chain polyamines and other components will vary depending on whether the cleaning composition is provided as a concentrate or as a work-in-use solution.

[0041] The solution to be used can be prepared from the concentrate by diluting it with water at a dilution ratio that provides a solution to be used with the desired cleaning properties. The water used to dilute the concentrate and form the composition to be used may be called diluent water or diluent and may vary depending on the location. Typical dilution ratios are approximately 1 to approximately 10,000, but will depend on factors such as water hardness and the amount of dirt to be removed. In one embodiment, the concentrate is diluted with water at a ratio of approximately 1:10 to approximately 1:10,000. More specifically, the concentrate is diluted with water at a ratio of approximately 1:100 to approximately 1:5,000. More specifically, the concentrate is diluted with water at a ratio of approximately 1:250 to approximately 1:2,000.

In other embodiments, the composition does not contain an alkali source and can unexpectedly provide effective stain removal. In compositions using alkali sources, an effective amount of one or more alkali sources should be considered to be an 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 solution used has a pH of about 8 to about 13. In certain embodiments, the solution used has a pH of about 9 to 11. Examples of suitable alkali sources for cleaning compositions include carbonate-based alkali sources, e.g., carbonate salts, e.g., alkali metal carbonates; caustic alkali-based alkali sources, e.g., alkali metal hydroxides; and other suitable alkali sources may include, but are not limited to, metal silicates, metasilicates, metal borates, and / or organic alkali sources.

[0045] Generally, alkali sources are usually available in either aqueous or powder form, both of which are useful when formulating the detergent composition. Alkalinity can be added to the composition in any form known in the art, including solid beads, granules, or particles dissolved in an aqueous solution, or a combination thereof.

[0046] Generally, cleaning compositions contain an alkali source in amounts of about 0% to about 99% by weight, about 0.005% to about 95% by weight, about 0.01% to about 90% by weight, about 0.015% to about 90% by weight, about 10% to about 90% by weight, about 20% to about 90% by weight, about 40% to about 90% by weight, about 50% to about 90% by weight, and about 50% to about 85% by weight, based on the total weight of the detergent composition.

As referred to herein, branched polyamines include C6-C20 polyamines, C8-C20 polyamines, C9-C20 polyamines, C8-C18 polyamines, C9-C18 polyamines, C10-C18 polyamines, or preferably C8-C12 polyamines. As referred to herein, branched polyamines contain alkyl chains of varying lengths and at least three amine groups in the branched structure. In a preferred embodiment, a branched polyamine suitable for use in the composition contains at least one branched structure, or at least two branched structures.

[0048] An example of a C6-C20 branched polyamine is N1,N1,N3-tris(3-aminopropyl)-N3-dodecylpropane-1,3-diamine[I], which has the following structure. [ka] Further examples of branched polyamines include the following structures. [ka] or [ka]

[0051] In a cleaning composition containing or not containing an alkali source, the composition has a pH of at least neutral to alkaline in order to provide an alkaline cleaning composition. The alkaline cleaning composition does not contain acids or acidulants, such as phosphorus-based acids. As a result, the long-chain polyamines in the alkaline cleaning composition are not neutralized amines, meaning they are not cationic polyamines.

[0052] Antifoaming surfactant The components of the cleaning composition may further include antifoaming surfactants. Examples of antifoaming surfactants include alkoxylated nonionic surfactants, polyoxypropylene-polyoxyethylene polymer compounds, and reverse polyoxypropylene-polyoxyethylene polymer compounds.

[0053] 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, and mixtures thereof. 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; and mixtures thereof.

[0054] Block polyoxypropylene-polyoxyethylene polymer compounds based on propylene glycol, ethylene glycol, glycerol, trimethylolpropane, and ethylenediamine as initiator-reactive hydrogen compounds. Examples of polymer compounds produced by the sequential propoxylation and ethoxylation of initiators are commercially available from BASF Corp. under the trade names Pluronic® and Tetronic®. Pluronic® compounds are bifunctional (two reactive hydrogen) 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 approximately 1,000 to approximately 4,000. Then, ethylene oxide is added so as to sandwich this hydrophobic substance between hydrophilic groups, and its length is controlled so that it constitutes approximately 10% to approximately 80% by weight 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; hydrophilic ethylene oxide is added to constitute about 10% to about 80% by weight of the molecule.

[0055] Blocked polyoxypropylene-polyoxyethylene polymer compounds are modified and essentially inverted by adding ethylene oxide to ethylene glycol to provide a hydrophilic substance of a specified molecular weight, and then adding propylene oxide to obtain a hydrophobic block on the outside (end) of the molecule. The hydrophobic portion of the molecule has a molecular weight of approximately 1,000 to approximately 3,100, and the central hydrophilic substance accounts for 10% to approximately 80% by weight of the final molecule. These inverted Pluronics® are manufactured by BASF Corporation under the trade name Pluronic®® surfactants.

In addition, although not limiting to the present invention, all listed ranges include a number defining the range, and each integer within the defined range includes an integer.

[0057] Additional functional ingredients The components of the cleaning composition can be further combined with various additional functional components suitable for use in cleaning and laundry applications of goods. In some embodiments, the cleaning composition containing an alkali source and a long-chain polyamine constitutes the majority, or even substantially all, of the total weight of the cleaning composition. In other embodiments, the cleaning composition containing an alkali source and a long-chain polyamine constitutes the majority, or even substantially all, of the total weight of the cleaning composition. For example, in some embodiments, it contains little to no additional functional components.

[0058] In other embodiments, additional functional components may be included in the cleaning composition. Functional components impart desired properties and functionality to the composition. For the purposes of this application, the term “functional component” includes materials that, when dispersed or dissolved in use and / or concentrated solution, provide beneficial properties in a particular use. Some specific examples of functional materials are discussed in more detail below, but the specific materials discussed are merely examples, and a variety of other functional components may be used.

In addition, although not limiting to the present invention, all listed ranges include a number defining the range, and each integer within the defined range includes an integer.

[0062] Nonionic surfactants Useful nonionic surfactants are generally characterized by the presence of organic hydrophobic and organic hydrophilic groups and are typically produced by the condensation of an organoaliphatic, alkylaromatic, or polyoxyalkylene hydrophobic compound with a hydrophilic alkaline oxide moiety, generally ethylene oxide or its polyhydration product, polyethylene glycol. In practice, any hydrophobic compound having a hydroxyl, carboxyl, amino, or amide group with a reactive hydrogen atom can condense with ethylene oxide, its polyhydrate adduct, or a mixture thereof with an alkoxylene such as propylene oxide to form a nonionic surfactant. The length of the hydrophilic polyoxyalkylene moiety that condenses with any particular hydrophobic compound can be easily adjusted to produce a water-dispersible or water-soluble compound with a desired balance between hydrophilic and hydrophobic properties. Useful nonionic surfactants include propylene glycol, ethylene glycol, glycerol, trimethylolpropane, and ethylenediamine-based block polyoxypropylene-polyoxyethylene polymer compounds as initiator-reactive hydrogen compounds. Examples of polymer compounds produced from the sequential propoxylation and ethoxylation of initiators are commercially available from BASF Corp. One class of compounds are bifunctional (two reactive hydrogen) compounds formed by the condensation of 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 about 1,000 to about 4,000. The ethylene oxide is then added so as to sandwich this hydrophobic substance between hydrophilic groups, and its length is controlled so as to constitute about 10% to about 80% by weight of the final molecule. Another class of compounds are 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, and the hydrophilic ethylene oxide is added so as to constitute about 10% to about 80% by weight of the molecule.

[0063] Condensation products of 1 mole of alkylphenol containing about 8 to about 18 carbon atoms in a linear or branched alkyl chain, or a single or double alkyl component, with about 3 to about 50 moles of ethylene oxide. The alkyl group may be represented, for example, by diisobutylene, diamyl, polymerized propylene, iso-octyl, nonyl, and di-nonyl. These surfactants may also be polyethylene, polypropylene, and polybutylene oxide condensates of alkylphenols. Examples of commercial compounds of this chemistry are commercially available under the trade names Igepal® from Rhone-Poulenc and Triton® from Union Carbide.

[0064] A condensation product of 1 mole of a saturated or unsaturated linear or branched alcohol having approximately 6 to 24 carbon atoms and approximately 3 to 50 moles of ethylene oxide. The alcohol portion may consist of a mixture of alcohols within the aforementioned carbon range, or of an alcohol having a specific number of carbon atoms within this range. Examples of similar commercial surfactants are available under the trade names Lutensol® and Dehydol® from BASF, Neodol® from Shell Chemical Co., and Alfonic® from Vista Chemical Co.

[0065] A condensation product of 1 mole of a saturated or unsaturated linear or branched carboxylic acid having approximately 8 to 18 carbon atoms and approximately 6 to 50 moles of ethylene oxide. The acid portion may consist of a mixture of acids within the carbon atom range defined above, or of acids having a specific number of carbon atoms within this range. 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.

[0066] In addition to ethoxylated carboxylic acids, commonly known as polyethylene glycol esters, other alkanate esters formed by reactions with glycerides, glycerol, and polyhydric (saccharide or sorbitan / sorbitol) alcohols have applications as described herein, particularly in specialized embodiments for indirect food additive applications. All of these ester moieties have one or more reactive hydrogen sites on their molecules that can be subjected to further acylation or ethylene oxide (alkoxide) addition to control the hydrophilicity of these substances. When adding these fatty esters or acylated carbohydrates to compositions of the present invention containing amylase and / or lipase enzymes, caution should be exercised due to the potential for incompatibility.

[0067] Examples of nonionic low-foaming surfactants include the following: Compounds from (1) that are essentially inverted by modifying them by adding ethylene oxide to ethylene glycol to provide a hydrophilic substance of a specified molecular weight; and then adding propylene oxide to obtain a hydrophobic block on the outside (end) of the molecule. The hydrophobic portion of the molecule has a molecular weight of about 1,000 to about 3,100, and the central hydrophilic substance accounts for 10% to about 80% by weight of the final molecule. These inverted Pluronics® are manufactured by BASF Corporation under the trademark Pluronic®® surfactants. Similarly, Tetronic®® 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 about 2,100 to about 6,700, and the central hydrophilic substance accounts for 10% to about 80% by weight of the final molecule.

[0068] Compounds modified by "capping" or "terminal blocking" the terminal hydroxyl group(s) (of the polyfunctional moiety) to reduce foaming in reaction with hydrophobic low molecular weights such as propylene oxide, butylene oxide, and benzyl chloride, and short-chain fatty acids, alcohols, or alkyl halides containing 1 to 5 carbon atoms, as well as mixtures thereof. Also included are reactants such as thionyl chloride, which converts terminal hydroxyl groups to chloride groups. Such modifications to terminal hydroxyl groups can result in fully blocked, blocked-heteric, heteric-blocked, or fully heteric nonionic substances.

[0078] Nonionic alkyl polysaccharide surfactants particularly suitable for use in this composition include those disclosed in U.S. Patent No. 4,565,647, Llenado, issued on January 21, 1986. These surfactants contain a hydrophobic group containing about 6 to about 30 carbon atoms and a polysaccharide, e.g., a polyglycoside, a hydrophilic group containing about 1.3 to about 10 saccharide units. Any reduced saccharide containing 5 or 6 carbon atoms can be used, e.g., glucose, galactose, and the galactosyl portion can be substituted for the glucosyl portion. (Optionally, the hydrophobic group may be bonded at positions 2, 3, 4, etc., thus resulting in glucose or galactose as opposed to glucosides or galactosides.) Saccharid-saccharid bonds may be, for example, between one position of an additional saccharide unit and positions 2, 3, 4, and / or 6 on the preceding saccharide unit.

[0079] Fatty acid amide surfactants suitable for use in this composition include those having the formula: R6CON(R7)2, where R6 is an alkyl group containing 7 to 21 carbon atoms, and each R7 is independently hydrogen, C1-C4 alkyl, C1-C4 hydroxyalkyl, or --(C2H4O) X H is given by the equation, where x is in the range of 1 to 3.

[0080] A useful class of nonionic surfactants includes alkoxylated amines, or more specifically, the class defined as alcohol alkoxylated / amination / alkoxylated surfactants. These nonionic surfactants are at least in part, with 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 It can be expressed by H, where R 20is an alkyl, alkenyl or other aliphatic group, or an alkyl-aryl group of 8 to 20 carbon atoms, 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.

These compounds are commercially represented by a product line marketed by Huntsman Chemicals as nonionic surfactants. Preferred chemicals in this class include Surfonic® PEA25 amine alkoxylates. Preferred nonionic surfactants for the compositions of the present invention include alcohol alkoxylates, EO / PO block copolymers, alkylphenol alkoxylates, and the like.

[0081] The paper, *Nonionic Surfactants*, edited by Schick, MJ, Vol. 1 of the Surfactant Science Series, Marcel Dekker, Inc., New York, 1983, is an excellent reference for a wide range of nonionic compounds commonly used in the practice of the present invention. A typical list of the nonionic class and species of these surfactants is described in U.S. Patent No. 3,929,678, issued December 30, 1975, to Laughlin and Heuring. Further examples are described in *Surface Active Agents and detergents* (Volumes I and II, Schwartz, Perry and Berch).

[0082] Semipolar nonionic surfactant Semipolar nonionic surfactants are another class of nonionic surfactants useful in the compositions of the present invention. Generally, semipolar nonionic substances are foaming agents and foam stabilizers, which may limit their application in CIP systems. However, in the compositional embodiments of the present invention designed for high-foaming purification methods, semipolar nonionic substances have immediate practical applications. Semipolar nonionic surfactants include amine oxides, phosphine oxides, sulfoxides, and their alkoxylated derivatives.

[0083] Amine oxides are tertiary amine oxides corresponding to the general formula, [ka] In the formula, the arrow is the conventional representation of a semipolar bond, R 1 , R 2 , and R 3 These can be aliphatic, aromatic, heterocyclic, alicyclic, or a combination thereof. Generally, in detergent-related amine oxides, R 1 However, it is an alkyl radical with approximately 8 to 24 carbon atoms, R 2 and R 3 However, it is an alkyl or hydroxyalkyl group with 1 to 3 carbon atoms, or a mixture thereof, R 2 and R 3 However, they can bond to each other via, for example, oxygen or nitrogen atoms, forming a ring structure, R 4 However, it is an alkali or a hydroxyalkylene group containing 2-3 carbon atoms, and n is in the range of 0 to about 20.

[0085] Useful semipolar nonionic surfactants also include water-soluble phosphine oxides having the following structure: [ka] In the formula, the arrow is the conventional representation of a semipolar bond, R 1 R is an alkyl, alkenyl, or hydroxyalkyl moiety with a chain length range of 10 to approximately 24 carbon atoms. 2 and R 3 Each of these is an alkyl moiety separately selected from alkyl or hydroxyalkyl groups containing 1 to 3 carbon atoms.

[0086] Examples of useful phosphine oxides include dimethyldecylphosphine oxide, dimethyltetradecylphosphine oxide, methylethyltetradecylphosphon oxide, dimethylhexadecylphosphine oxide, diethyl-2-hydroxyoctyldecylphosphine oxide, bis(2-hydroxyethyl)dodecylphosphine oxide, and bis(hydroxymethyl)tetradecylphosphine oxide.

[0087] Semipolar nonionic surfactants useful in this specification also include water-soluble sulfoxide compounds having a structure. [ka] In the formula, the arrow is the conventional representation of a semipolar bond, R 1 R consists of approximately 8 to 28 carbon atoms, 0 to 5 ether bonds, and 0 to 2 alkyl or hydroxyalkyl moieties of hydroxyl substituents. 2 This is an alkyl moiety consisting of alkyl and hydroxyalkyl groups having 1 to 3 carbon atoms.

[0088] Useful examples of these sulfoxides include dodecyl methyl sulfoxide; 3-hydroxytridecyl methyl sulfoxide; 3-methoxytridecyl methyl sulfoxide; and 3-hydroxy-4-dodecoxybutyl methyl sulfoxide.

[0089] Semipolar nonionic surfactants for the compositions of the present invention include dimethylamine oxides, such as lauryldimethylamine oxide, myristyldimethylamine oxide, cetyldimethylamine 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, specific examples of which include octyldimethylamine oxide, nonyldimethylamine oxide, decyldimethylamine oxide, undecyldimethylamine oxide, dodecyldimethylamine oxide, isododecyldimethylamine oxide, tridecyldimethylamine oxide, tetradecyldimethylamine oxide, pentadecyldimethylamine oxide, hexadecyldimethylamine oxide, heptadecyldimethylamine oxide, and These are tadecyldimethylamine oxide, dodecyldipropylamine oxide, tetradecyldipropylamine oxide, hexadecyldipropylamine oxide, tetradecyldibutylamine oxide, octadecyldibutylamine oxide, bis(2-hydroxyethyl)dodecylamine oxide, bis(2-hydroxyethyl)-3-dodecoxy-1-hydroxypropylamine oxide, dimethyl-(2-hydroxydodecyl)amine oxide, 3,6,9-trioctadecyldimethylamine oxide, and 3-dodecoxy-2-hydroxypropyldi-(2-hydroxyethyl)amine oxide.

[0090] 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, and mixtures thereof. 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; and mixtures thereof.

[0091] Anionic surfactants Surfactants classified as anionic substances because the hydrophobic portion of the substance has a negative charge, or surfactants whose hydrophobic portion 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. Of the cations (counterions) associated with these polar groups, sodium, lithium, and potassium confer water solubility, ammonium and substituted ammonium ions provide both water and oil solubility, and calcium, barium, and magnesium promote oil solubility. As those skilled in the art will understand, anionic substances are excellent cleaning surfactants and are therefore preferred additives to heavy detergent compositions.

[0092] Suitable anionic sulfate surfactants for use in the compositions of the present invention include alkyl ether sulfates, alkyl sulfates, linear and branched primary and secondary alkyl sulfates, alkyl ethoxy sulfates, fatty oleylglycerol sulfates, alkylphenol ethylene oxide ether sulfates, and C5-C 17Examples include acyl-N-(C1-C4 alkyl) and -N-(C1-C2 hydroxyalkyl) glucamine sulfates, as well as 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 condensation products of sulfate or ethylene oxide with nonylphenol (usually having 1-6 oxyethylene groups per molecule).

[0093] Suitable anionic sulfonate surfactants for use in this composition include alkyl sulfonates, linear and branched primary and secondary alkyl sulfonates, and aromatic sulfonates with or without substituents.

[0094] Suitable anionic carboxylate surfactants for use in this composition include carboxylic acids (and salts), e.g., alkanic acids (and alkanoates), ester carboxylic acids (e.g., alkyl succinates), ether carboxylic acids, sulfonated fatty acids, e.g., sulfonated oleic acid. Such carboxylates include alkylethoxycarboxylates, alkylarylethoxycarboxylates, alkylpolyethoxypolycarboxylate surfactants, and soaps (e.g., alkylcarboxyls). Useful secondary carboxylates in this composition include those containing carboxyl units connected to a secondary carbon. The secondary carbon may be in a cyclic structure, for example, as in p-octylbenzoic acid or alkyl-substituted cyclohexylcarboxylate. Secondary carboxylate surfactants typically do not contain ether bonds, ester bonds, or hydroxyl groups. Furthermore, they typically lack a nitrogen atom in the head group (amphiphilic moiety). Suitable secondary soap surfactants typically contain 11 to 13 total carbon atoms, but more carbon atoms (e.g., up to 16) may be present. Other suitable carboxylates include, for example, acyl glutamates, acyl peptides, sarcosinates (e.g., N-acyl sarcosinates), and acyl amino acids (and salts) such as taurates (e.g., fatty acid amides of N-acyl taurates and methyl taurides).

[0095] Suitable anionic surfactants include alkyl or alkylarylethoxycarboxylates of the following formulas: RO-(CH2CH2O) n (CH2) m -CO2X(3) In the formula, R is C8~C 22 It is an alkyl group, or [ka] And R 1 C4~C 16It is an alkyl group, where n is an integer from 1 to 20, m is an integer from 1 to 3, and X is a counterion such as hydrogen, sodium, potassium, lithium, or ammonium, or an amine salt such as monoethanolamine, diethanolamine, or triethanolamine. In some embodiments, n is an integer from 4 to 10, and m is 1. In some embodiments, R is C8 to C 16 It is an alkyl group. In some embodiments, R is C 12 ~C 14 It is an alkyl group, where n is 4 and m is 1.

[0096] In other embodiments, R is [ka] And R 1 C6~C 12 It is an alkyl group. In yet another embodiment, R 1 It is a C9 alkyl group, where n is 10 and m is 1.

[0097] Such alkyl and alkylaryl ethoxycarboxylates are commercially available. These ethoxycarboxylates are typically available in acid form, and they can be readily converted to anionic or salt form. A commercially available carboxylate is Neodox 23-4, C 12~13 Examples include alkyl polyethoxy(4)carboxylic acid (Shell Chemical) and Emcol CNP-110, C9 alkylaryl polyethoxy(10)carboxylic acid (Witco Chemical). Carboxylates, for example, product Sandopan® DTC, C 13 Alkyl polyethoxy(7)carboxylic acids are also available from Clariant.

[0098] Cationic surfactants Surface active substances are classified as cationic if the charge on the hydrotrope portion of the molecule is positive. Surfactants that are cationic (e.g., alkylamines) after the hydrotrope is not charged unless the pH is near or below neutral also belong to 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 dominated by nitrogen-containing compounds, perhaps because the synthetic pathway from nitrogen to cationic surfactants is simple and easy, producing high-yield products, and thus making nitrogen cationic surfactants cheaper.

[0099] Cationic surfactants preferably refer to compounds containing at least one long-chain hydrophobic group and at least one positively charged nitrogen atom. The long-chain group may be directly bonded to the nitrogen atom by simple substitution, or more preferably indirectly bonded by a crosslinking functional group(s) in so-called interrupted alkylamines and amidoamines. Such functional groups can make the molecule more hydrophilic and / or more water-dispersible, allowing it to dissolve more readily in water by co-surfactant mixtures and / or making it water-soluble. To increase water solubility, additional primary, secondary, or tertiary amino groups may be introduced, or the amino nitrogen may be quaternized using a low molecular weight alkyl group. Furthermore, the nitrogen may be part of a branched or linear portion with varying degrees of unsaturation, or part of a saturated or unsaturated heterocyclic ring. In addition, cationic surfactants may contain complex bonds having two or more cationic nitrogen atoms.

[0100] Surfactant compounds classified as amine oxides, amphoteric substances, and zwitterionic compounds are generally cationic in solutions with near-neutral to acidic pH, overlapping with the classification of surfactants. Polyoxyethylated cationic surfactants generally behave like nonionic surfactants in alkaline solutions and like cationic surfactants in acidic solutions.

[0101] The majority of commercially available cationic surfactants can be subdivided into four main classes and additional subgroups known to those skilled in the art, as 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 products such as alkylbenzyldimethylammonium salts, alkylbenzene salts, heterocyclic ammonium salts, and tetraalkylammonium salts. Cationic surfactants are known to possess a variety of properties that can be beneficial in this composition. These desirable properties may include cleaning power in compositions with neutral or sub-neutral pH, antimicrobial efficacy, and thickening or gelling in conjunction with other agents.

[0102] A cationic surfactant useful in the composition of the present invention is formula R 1 m R 2 x Y L Examples include those having Z, where each R 1 It contains a linear or branched alkyl or alkenyl group, optionally substituted with up to three phenyl or hydroxyl groups, and has up to four of the following structures: [ka] Alternatively, it is an organic group optionally interrupted by isomers or mixtures of these structures, containing approximately 8 to 22 carbon atoms. 1The group may contain up to 12 additional ethoxy groups. m is a number from 1 to 3. Preferably, there is one or fewer R groups in the molecule. 1 The group has 16 or more carbon atoms when m is 2, or more than 12 carbon atoms when m is 3. Each R 2 This is an alkyl or hydroxyalkyl group containing 1 to 4 carbon atoms or a benzyl group, and has 1 or fewer R groups in the molecule. 2 is benzyl, and x is a number from 0 to 11, preferably from 0 to 6. The remaining positions of any carbon atoms on the Y group are occupied by hydrogen.

[0103] Y is not limited, [ka] Or it may be a mixture thereof. Preferably, L is 1 or 2, and when L is 2, the Y group has 1 to about 22 carbon atoms and 2 free carbon single bonds. 1 and R 2 The components are separated by a portion selected from analogs (preferably alkylene or alkenylene). Z is a water-soluble anion such as a halide anion, sulfate anion, methyl sulfate anion, hydroxide anion, or nitrate anion, with chloride anions, bromide anions, iodide anions, sulfate anions, or methyl sulfate anions being particularly preferred in terms of the number of components that impart electrical neutrality to the cationic components.

[0104] Amphoteric surfactants Amphoteric or amphoteric electrolyte surfactants contain both basic and acidic hydrophilic groups and organic hydrophobic groups. These ionic entities may 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, sulfonates, sulfates, phosphonates, or phosphates provide a negative charge.

[0105] Amphoteric surfactants can be broadly described as derivatives of aliphatic secondary and tertiary amines, where the aliphatic radical may be linear or branched, and one of the aliphatic substituents comprises about 8 to 18 carbon atoms, and one comprises an anionic water-soluble group, e.g., carboxy, sulfo, sulfato, phosphat, or phosphono. Amphoteric surfactants are known to those skilled in the art and are subdivided into two main classes, as described in the "Surfactant Encyclopedia" Cosmetics & Toiletries, Vol. 104(2) 69-71 (1989), which is incorporated herein 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-alkyl amino acids and their salts. Some amphoteric surfactants may be assumed to fit into both classes.

[0106] Amphoteric surfactants can be synthesized by methods known to those skilled in the art. For example, 2-alkylhydroxyethylimidazoline is synthesized by condensation and ring closure of a long-chain carboxylic acid (or derivative) with a dialkylethylenediamine. Commercially available amphoteric surfactants are derivatized using, for example, chloroacetic acid or ethyl acetate by subsequent hydrolysis and ring opening of the imidazoline ring by alkylation. During alkylation, one or two carboxyalkyl groups react to form ether bonds with a tertiary amine and a different alkylating agent, yielding different tertiary amines.

[0107] The long-chain imidazole derivatives used in the present invention generally have the following general formula: [ka] In the formula, R is an acyclic hydrophobic group containing about 8 to about 18 carbon atoms, and M is a cation, generally sodium, for neutralizing the charge of the anion. Commercially well-known amphoteric compounds derived from imidazolines that can be used in this composition include, for example, cocoamphopropionate, cocoamphocarboxy-propionate, cocoamphoglycinate, cocoamphocarboxy-glycinate, cocoamphopropyl-sulfonate, and cocoamphocarboxy-propionic acid. Amphocarboxylic acids can be produced from aliphatic imidazolines, where the dicarboxylic acid functional group of the amphodicarboxylic acid is diacetic acid and / or dipropionic acid.

[0108] In this specification, the carboxymethylated compounds (glycinates) described above are often referred to as betaines. Betaines are a special class of amphoteric compounds described below in the following section entitled Zwitterionic surfactants.

[0109] Long-chain N-alkyl amino acids are readily prepared by the reaction RNH2, where R is C8~C 18 These are fatty amines having linear or branched alkyl, halogenated carboxylic acids. Alkylation of the primary amino group of an amino acid yields secondary and tertiary amines. The alkyl substituent may have additional amino groups providing multiple reactive nitrogen centers. The most commercially available N-alkylamine acids are alkyl derivatives of β-alanine or β-N(2-carboxyethyl)alanine. Examples of commercially available N-alkylamino acid amphoteric electrolytes applicable to the present invention include alkyl β-aminodipropionates, RN(C2H4COOM)2 and RNHC2H4COOM. In embodiments, R may 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.

[0110] Suitable amphoteric surfactants include those derived from coconut products such as coconut oil or coconut fatty acids. Additional suitable coconut-derived surfactants include, as part of their structure, an ethylenediamine moiety, an alkanolamide moiety, an amino acid moiety, such as glycine, or a combination thereof, and an aliphatic substituent of about 8 to 18 (e.g., 12) carbon atoms. Such surfactants can also be considered alkylamphodicarboxylic acids. These amphoteric surfactants are 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 + It may include a chemical structure represented as (CH2-CO2Na)2-CH2-CH2-OH. Disodium cocoamphodipropionate is one preferred amphoteric surfactant, marketed by Rhodia Inc. (Cranbury, NJ) under the trade name Miranol® FBS. Another preferred coconut-derived amphoteric surfactant having the chemical name disodium cocoamphodiacetate is similarly marketed by Rhodia Inc. (Cranbury, NJ) under the trade name Mirataine® JCHA.

[0111] A typical list of amphoteric classes and species of these surfactants is described in U.S. Patent No. 3,929,678, published December 30, 1975, to Laughlin and Heuring. 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.

[0112] Zwitterionic surfactants 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 optionally a sulfonium or phosphonium ion, a charged carboxyl group, and an alkyl group. Zwitterionic compounds generally contain cationic and anionic groups that ionize to approximately the same degree in the isoelectric region of the molecule, potentially leading to a strong "internal salt" attraction between positive and negative charge centers. Examples of such zwitterionic synthetic surfactants include derivatives of aliphatic quaternary ammonium, phosphonium, and sulfonium compounds, in which the aliphatic group may be linear or branched, and one of the aliphatic substituents contains 8 to 18 carbon atoms and one contains an anionic water-soluble group, such as a carboxyl, sulfonate, sulfate, phosphate, or phosphonate.

[0113] Betaine and sultaine surfactants are examples of zwitterionic surfactants for use herein. The general formulas of these compounds are as follows: [ka] In the formula, R 1 Y comprises an alkyl, alkenyl, or hydroxyalkyl radical with 8 to 18 carbon atoms having 0 to 10 ethylene oxide moieties and 0 to 1 glyceryl moiety, Y is selected from the group consisting of nitrogen atoms, phosphorus atoms, and sulfur atoms, and R 2 x is an alkyl group or monohydroxyalkyl group containing 1 to 3 carbon atoms, where x is 1 when Y is a sulfur atom, and 2 when Y is a nitrogen atom or a phosphorus atom, and R 3Z is an alkylene or hydroxyalkylene or hydroxyalkylene with 1 to 4 carbon atoms, and Z is a radical selected from the group consisting of a carboxylic acid group, a sulfonic acid group, a sulfate group, a phosphonic acid group, and a phosphate group.

[0114] Examples of zwitterionic surfactants having the structures listed above include 4-[N,N-di(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-trioxatetracosanphosphonio]-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, and 3-(N,N-dimethyl- Examples include N-hexadecylammonio)-2-hydroxy-propane-1-sulfonate, 4-[N,N-di(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-di(3-hydroxypropyl)-N-hexadecylammonio]-2-hydroxypentane-1-sulfate. The alkyl groups contained in these detergent surfactants may be linear or branched and saturated or unsaturated.

[0115] Suitable zwitterionic surfactants for use in this composition include betaine with a general structure. [ka] These surfactant betaines typically do not exhibit strong cationic or anionic properties at extreme pH values, and they do not exhibit low water solubility in the isoelectric point range. Unlike "external" quaternary ammonium salts, betaines are compatible with anionic substances. 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.

[0116] 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.

[0117] The zwitterionic class and a typical list of species of these surfactants 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" (Vol.I and II by Schwartz, Perry and Berch). Each of these references is incorporated herein by reference in its entirety.

[0118] Antifoaming agent The compositions and methods of the present invention may optionally contain an antifoaming agent. The antifoaming agent may be particularly suitable for embodiments that include a foaming surfactant such as anionic surfactants. Generally, possible antifoaming agents include silica and silicones; fatty acids or esters; alcohols; sulfates or sulfonates; amines or amides; halogen compounds such as fluorochloro hydrocarbons; vegetable oils, waxes, mineral oils, and their sulfonated or sulfated derivatives; fatty acids and / or soaps thereof such as alkalis and alkaline earth metal soaps; and phosphates and phosphate esters such as alkyls and alkali diphosphates, and tributyl phosphate in particular; and mixtures thereof.

[0119] In some embodiments, the composition may include a food-grade antifoaming agent or defoamer, given its application to this method. For this purpose, one of the more effective antifoaming agents is silicone. Silicones such as dimethyl silicone, glycol polysiloxane, methylphenol polysiloxane, trialkyl or tetraalkylsilane, hydrophobic silica defoamers, and mixtures thereof can all be used for defoaming applications. Commonly available commercial defoamers include ARDEFOAM® from Armour Industrial Chemical Company, which is a bound silicone in an organic emulsion; FOAM KILL® or KRESSEO® from Krusable Chemical Company, which are silicone and non-silicone type defoamers and silicone esters; and ANTI-FOAM A® and DC-200 from Dow Corning Corporation, both of which are food-grade silicones.

[0120] enzyme In some embodiments, the composition may further contain enzymes. Preferably, in cleaning compositions that do not contain an alkali source, enzymes and water constitute the majority of the cleaning composition.

[0121] Since enzymes are proteins, it is important that other components of the composition do not denature the enzyme, rendering it ineffective for its intended purpose. For preferred cleaning compositions incorporating active or otherwise stabilized enzymes, the pH of the composition is important. That is, the pH of the enzyme-containing composition must be such that the enzyme component remains stable and undenatured. Such a pH may be approximately neutral or near neutral, or about 7–8. For specific enzymes, such a pH may be about 7 and about 11, or about 7–11. As those familiar with the art will recognize, there is a difference between a stable enzyme and an active enzyme. For example, an enzyme can be incorporated into a composition at pH 6 and may be considered stable but inactive. However, if the enzyme is then used in an alkaline composition / alkaline application where the pH of the composition is changed (e.g., to 6–11), the enzyme will become active when the pH changes to a higher "ideal" pH (e.g., pH 11).

[0122] Amylase is an example of an enzyme useful in washing compositions. Examples of amylases that can be used include alpha-amylase derived from Bacillus licheniformis, B. amyloliquiefaciens, or B. stearothermophilus, as well as their developed forms improved for use in washing and washing compositions. Novozymes and Genencor sell commercially available alpha-amylase derived from one or all of the above bacterial species. Novozymes further offers alpha-amylase derived from Aspergillus niger and A. oryzae.

[0123] Proteases are examples of enzymes useful in washing compositions. Proteases can be derived from microorganisms such as yeast, mold, or bacteria. Examples of proteolytic enzymes that can be used in washing compositions include sabinases. Proteases derived from Bacillus lentus, Bacillus licheniformis, Bacillus amyloliquefaciens, and Bacillus alcalophilus are commercially available from companies such as Genencor International, Solvay Enzymes, and Novozymes.

[0124] Preferred enzymes provide good protein removal and washing performance, leave no residue, are easy to formulate, and form stable products. Savinase, commercially available from Novozymes, is a serine-type endoprotease that is active in a pH range of 8–12 and a temperature range of 20°C–60°C. As a further example, Alcalase, commercially available from Novozymes, is derived from Bacillus licheniformis and is active in a pH range of 6.5–8.5 and a temperature range of 45°C–65°C. Esperase, commercially available from Novozymes, is derived from Bacillus sp. and has an alkaline pH activity range and a temperature range of 50°C–85°C.

[0125] A mixture of different enzymes may be incorporated into the washing composition. While various specific enzymes have been described, it should be understood that any enzyme, such as a protease, that can confer the desired proteolytic activity to the composition may be used. The compositions of the present invention include about 0% to about 25% by weight of enzyme, about 0.0005% to about 15% by weight of enzyme, about 0.001% to about 10% by weight of enzyme, about 0.001% to about 5% by weight of enzyme, and about 0.001% to about 1% by weight of enzyme. In addition, although not limiting to the present invention, all listed ranges include a number defining the range, and each integer within the defined range includes such numbers.

[0126] Keelland In some embodiments, the composition may further include a chelant. In this specification, chelation means the binding or complex formation of a bidentate or polydentate ligand. These ligands are often organic compounds and are called chelants, chelators, chelating agents, and / or metal ion sequestering agents. Chelating agents form multiple bonds with a single metal ion. Chelants are chemicals that form soluble complex molecules with specific metal ions, inactivating those ions so that they cannot react normally with other elements or ions to form precipitates or scales. Ligands form chelate complexes with a substrate. The term refers to a complex in which a metal ion is bound to two or more atoms of the chelant.

[0127] Suitable aminocarboxylic acid type chelating agents include acids or their alkali metal salts. Some examples of aminocarboxylic acid materials include aminoacetates and their salts. Some examples include: N-hydroxyethylaminodiacetic acid, hydroxyethylenediaminetetraacetic acid, nitrilotriacetic acid (NTA), ethylenediaminetetraacetic acid (EDTA), N-hydroxyethyl-ethylenediaminetriacetic acid (HEDTA), diethylenetriaminepentaacetic acid (DTPA), and alanine-N,N-diacetic acid, as well as mixtures thereof. Particularly useful aminocarboxylic acid materials that contain little to no NTA and are phosphorus-free include N-hydroxyethylaminodiacetic acid, ethylenediaminetetraacetic acid (EDTA), hydroxyethylenediaminetetraacetic acid, diethylenetriaminepentaacetic acid, N-hydroxyethyl-ethylenediaminetriacetic acid (HEDTA), diethylenetriaminepentaacetic acid (DTPA), methylglycinediacetic acid (MGDA), aspartic acid-N,N-diacetic acid (ASDA), glutamic acid-N,N-diacetic acid (GLDA), ethylenediaminesuccinic 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.

[0128] Other chelates include aminocarboxylates, such as ethylenediaminetetraacetate, N-hydroxyethylethylenediamine triacetate, nitrilo-triacetate, ethylenediaminetetrapropionate, triethylenetetraamine hexaacetate, diethylenetriamine pentaacetate, and ethanol diglycine, alkali metals, ammonium, and substituted ammonium salts thereof, as well as mixtures thereof. Preferred chelating agents include aminocarboxylates, aminophosphonates, polyfunctional substituted aromatic chelating agents, and mixtures thereof. Exemplary chelates include amino acid-based chelates, and preferably citric acid, tartaric acid, and glutamic acid-N,N-diacetic acid and its derivatives, and / or phosphonate-based chelates.

[0129] Other keyants include homopolymers and copolymers of polycarboxylic acids and their partially or completely neutralized salts, as well as monomeric polycarboxylic acids and hydroxycarboxylic acids and their salts. Preferred salts of the above compounds are ammonium and / or alkali metal salts, namely lithium, sodium, and potassium salts, with sodium salts such as sodium sulfate being particularly preferred.

[0130] Other keyants include polycarboxylic acid polymers. Representative polycarboxylic acid polymers suitable for rinse compositions include, in particular, aminocarboxylic acids, water-soluble acrylic polymers, polymaleic acid homopolymers, and maleic acid polymers, for preparing rinse solutions under final use conditions. Such polymers include polyacrylic acid, polymethacrylic acid, acrylic acid-methacrylic acid copolymer, hydrolyzed polyacrylamide, hydrolyzed methacrylamide, hydrolyzed acrylamide-methacrylamide copolymer, hydrolyzed polyacrylonitrile, hydrolyzed polymethacrylonitrile, hydrolyzed acrylonitrile-methacrylonitrile copolymer, or mixtures thereof. Water-soluble salts or partial salts of these polymers, such as alkali metal (e.g., sodium or potassium) or ammonium salts of each of these polymers, can also be used.

[0131] Furthermore, phosphonates or phosphonate metal ion chelating agents can also be used. In some embodiments, phosphonates and / or phosphonate metal ion chelating agents can be used alone, without polycarboxylic acid polymers. Examples of such useful phosphonic acids include mono, di, tri, and tetraphosphonic acids, which may also contain groups that can form anions under alkaline conditions, such as carboxy, hydroxy, and thio.

[0132] Water-adjusting polymer In one embodiment, the composition optionally comprises a water-modifying polymer(s). In some embodiments, the water-modifying polymer is a secondary builder or scale inhibitor for the composition. According to one embodiment, the water-modifying polymer may be a non-phosphorus polymer. In one embodiment, the water-modifying polymer is a nonionic surfactant. In one embodiment, the water-modifying polymer is a polycarboxylic acid and / or a hydrophobically modified polycarboxylic acid. An example of polyacrylic acid is commercially available as Acusol® 445N (Dow Chemical). In further embodiments, a neutralized polycarboxylic acid polymer is used as the water-modifying polymer. An example of a neutralized polycarboxylic acid is commercially available as Acumer® 1000 (Rohm & Haas Company).

[0133] In further embodiments, the water-modifying polymer may be a polycarboxylate or related copolymer. A polycarboxylate refers to a compound having multiple carboxylate groups. Various such polycarboxylate polymers and copolymers are known, described in patents and other literature, and are commercially available. An example of a polycarboxylate that can be used as a builder and / or water-modifying polymer is pendant carboxylate (-CO2 -Examples of polycarboxylates that have a ) group include, but are not limited to, acrylic homopolymers, polyacrylic acid, maleic acid, maleic acid / olefin copolymers, sulfonated copolymers or terpolymers, acrylic acid / 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. In further embodiments, polycarboxylates that can be used as builders and / or water-adjusting polymers include, but are not limited to, homopolymers and copolymers of polyacrylates; polyacrylates; polymethacrylates; non-carboxylated materials, such as copolymers of polyolefins and polymaleic acid, such as olefin hydrides and maleic acid hydrides; and derivatives and salts of all thereof. Additional descriptions of exemplary polycarboxylates and polyacrylates are provided in U.S. Patents 7,537,705 and 3,887,806.

[0134] In further embodiments, the water-adjusting polymer may be a polyacrylate or a related copolymer. Suitable polyacrylates, polyacrylate homopolymers and copolymers, polyolefin-based and polymaleic acid-based polymers according to the present invention may be organic compounds, such as both polymer agents and small molecule agents, such as polyanionic compositions, such as polyacrylic acid compounds. The polymer agent usually includes a polyanionic composition such as a polyacrylic acid compound. For example, exemplary commercially available acrylic acid-type polymers include acrylic acid polymers, methacrylic acid polymers, acrylic acid-methacrylic acid copolymers, and water-soluble salts of such polymers. These include polyelectrolytes, such as water-soluble acrylic polymers, such as polyacrylic acid, maleic acid / olefin copolymers, acrylic acid / maleic acid copolymers, polymethacrylic acid, acrylic acid-methacrylic acid copolymers, hydrolyzed polyacrylamide, hydrolyzed polymethacrylamide, hydrolyzed polyamide-methacrylamide copolymers, hydrolyzed polyacrylonitrile, hydrolyzed polymethacrylonitrile, hydrolyzed acrylonitrile-methacrylonitrile copolymers, hydrolyzed methacrylamide, hydrolyzed acrylamide-methacrylamide copolymers, and combinations thereof. Such polymers, or mixtures thereof, may include water-soluble salts or partial salts of these polymers, and for example, alkali metal (e.g., sodium or potassium) or ammonium salts of each of them may also be used.

[0136] Cleaning method The cleaning method is particularly suitable for removing lip makeup stains. While we don't want to adhere strictly to scientific theory, it is believed that the hydrophobic components of lip makeup stains make them particularly difficult to remove from the soiled substrate. The hydrophobic components of lip cosmetics can be oils, viscous solids, or waxes, depending on the viscosity of the final product. For example, lip gloss rolled on the lips tends to be a more viscous liquid than lip gloss applied with fingertips. Naturally, roll-on lip glosses are likely to contain more oil and solids or waxes than fingertip lip glosses. The hydrophobic components of lip cosmetics can be natural or synthetic.The following is a non-exclusive list of hydrophobic materials found in lip cosmetics: apple (Pyrus Malus) peel wax, avocado (Persea Gratissima) wax, bayberry (Myrica cerifera) wax, beeswax, candelilla (Euphorbia cerifera) wax, canola oil, carnauba (Copernicia cerifera) wax, castor oil, ceresin, cetyl alcohol, cetyl esters, cocoa (Theobroma cacao) butter, coconut (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, olive (Olea europaea) oil, orange (Citrus aurantium) Dulcis) peel wax, uricuri wax, oxidized beeswax, oxidized microcrystalline, ozokerite, palm kernel wax, paraffin, PEG-6 beeswax, PEG-8 beeswax, PEG-12 beeswax, PEG-20 beeswax, PEG-12 carnauba wax, petrolatum, yellow petrolatum, potassium oxidized microcrystalline wax, rice (Oryza sativa) wax, sesame (Sesamum indicum) oil, shea butter (Butyrospermum parkii), shellac wax, brewer's lees wax, stearic acid, sulfurized jojoba oil, synthetic beeswax, synthetic candelilla wax, synthetic carnauba wax, synthetic wood wax, synthetic jojoba oil, synthetic waxes, and vegetable oils. Additional materials found in lip cosmetics include silicones, such as dimethicone, as well as other pigments, dyes, colorants, and fragrances.

[0137] It is understood that the compositions disclosed herein can remove lip makeup stains having the above-mentioned hydrophobic and other materials, as well as those not included in the above list.

[0138] The method is particularly well suited for removing lip cosmetic stains that accumulate on all types of fabric substrates, such as textiles and other hard surfaces. The cleaning method involves contacting a fabric substrate or other hard surface that needs to be cleaned of lip cosmetic stains, including, for example, lipstick, lip stain, lip gloss, lip balm, and / or lip cream. In one embodiment, the fabric substrate or hard surface is soiled with waxy, oily, and / or greasy stains. Any means of contact, such as immersion, spraying, dripping, wiping, etc., can be used to bring the fabric substrate or hard surface into contact with the alkaline cleaning composition. Included within the scope of the contact described, the fabric substrate and / or hard surface may also be immersed in the alkaline composition, which may include a pretreatment or cleaning cycle. As a result of the contact step, the surface is cleaned and the stains are removed.

[0139] In one embodiment, the surface is a fabric substrate such as laundry. Exemplary laundry includes, for example, items or articles that are washed in a washing machine. Generally, laundry refers to any item or article made from, or containing, woven materials, fabrics, nonwovens, and knitted fabrics. Examples of woven materials include natural or synthetic fibers such as silk fibers, linen fibers, cotton fibers, polyester fibers, polyamide fibers such as nylon, acrylic fibers, acetate fibers, and blends thereof, including cotton and polyester blends. The fibers may be treated or untreated. An example of treated fibers is flame-retardant treated fibers. It should be understood that the term “linen” is often used to describe certain types of laundry items, such as bed sheets, pillowcases, towels, etc. The present invention additionally provides compositions and methods for treating non-laundry articles and surfaces, including hard surfaces. Washing of woven and laundry described herein may be manual washing. In another embodiment, the substrate is washed in a washing machine.

[0140] For cleaning, immersion (or pretreatment), and / or other hard surface treatment applications, branched polyamines can be added to the cleaning composition in the solution used. Alternatively, a fully formulated cleaning composition can be provided. For laundry applications, the pretreatment concentrate can be applied as a spray onto the substrate requiring treatment. Contact time can vary from a few seconds to several minutes. In other embodiments, lower concentrations of the cleaning composition can be used for pre-immersion applications. In such embodiments, contact time can vary from several minutes to several hours.

[0141] A first step of diluting and / or preparing an aqueous solution of use (for example, from a solid) may also be included in the method. An exemplary dilution step involves bringing a liquid and / or solid composition into contact with water. The compositions of the present invention include concentrated compositions and compositions of use. For example, a concentrated composition may be diluted with water, for example, to form a composition of use. In one embodiment, a concentrated composition may be diluted to a solution of use before application to an object. For economic reasons, concentrates are sold, and end users can dilute the concentrate with water or an aqueous diluent to a solution of use. The level of the active ingredient in a concentrated composition is determined by the intended dilution ratio and the desired activity of the active ingredient in the concentrate. Generally, dilutions of about 1 fluid ounce to about 10 gallons of water, from about 10 fluid ounces to about 1 gallon of water, are used with respect to aqueous compositions. In some embodiments, when used for laundry purposes, the concentrated composition can be diluted with a dilution ratio of about 0.1 g / L to about 100 g / L relative to the diluent, about 0.5 g / L to about 10.0 g / L relative to the diluent, about 1.0 g / L to about 4.0 g / L relative to the diluent, or about 1.0 g / L to about 2.0 g / L relative to the diluent. In other embodiments, the composition used may consist of about 0.01% to about 10% by weight of the concentrated composition and about 90% to about 99.99% by weight of the diluent, or about 0.1% to about 1% by weight of the concentrated composition and about 99% to about 99.9% by weight of the diluent.

[0142] Alkaline cleaning compositions may be provided in a ready-to-use active substance level that provides a desired amount of the active substance of the composition's components, and / or in a concentrated composition. In one embodiment, branched polyamines and / or additional surfactants are provided at concentrations of about 100 ppm to about 10,000 ppm in the solution of use, about 100 ppm to about 800 ppm in the solution of use, about 100 ppm to about 400 ppm in the solution of use, or about 200 ppm to about 300 ppm in the solution of use.

[0143] In one embodiment, the alkaline cleaning composition, in the solution used, comes into contact with the textile substrate and / or other hard surface that requires cleaning and has a pH of about 7.5 to about 13.5.

[0144] In one embodiment, the alkaline cleaning composition is in contact with the textile substrate and / or other hard surface for a sufficient time to remove the dirt, for example, from a few seconds to several hours. In some embodiments, the cleaning composition can be used in either a cleaning or pre-soaking situation, and the article is in contact with the composition of the present invention for a time effective for cleaning the article, at a working temperature of at least about 100°F to about 140°F, at least about 100°F to about 160°F, or at least about 100°F to about 180°F. This time is preferably a minimum of 1 hour or 2 hours and a maximum of 8 hours.

[0145] Alkaline cleaning compositions can be used alone to treat articles, such as textiles, or in combination with conventional detergents suitable for the articles being treated. The compositions can be used in a variety of ways with conventional detergents; for example, the compositions can be compounded with conventional detergents. In other embodiments, the compositions can treat articles as a separate additive from conventional detergents. When used as a separate additive, the compositions can come into contact with the articles being treated at any time. For example, the compositions can come into contact with the articles before, after, or substantially simultaneously with contact with the selected detergent.

[0149] Example 1 The cleaning power of various laundry formulations against lip makeup stains was measured using a tergometer. The detergent formulations shown in Figure 1 were evaluated using a caustic detergent composition containing a branched polyamine (Amine 739) surfactant, compared to conventional alkoxylate surfactants at a surfactant level of 450 ppm.

[0150] Apparatus: Tergotometer with 1 L pot and water bath

[0151] procedure: 1. Read the unwashed swatch of the lot number used in the test with a HunterLab Color Quest spectrophotometer to determine the average initial (pre-wash) L value.

[0152] 2. Next, program the tergotometer to a desired washing temperature of 120°F and heat the water bath to that temperature.

[0153] 3.1 liters of 5 grain (gpg) water were added to each tergotometer pot and brought to equilibrium at 120°F.

[0154] 4. Weigh the detergent and place it in the tergotometer pot. Stir the detergent for 30 seconds to 1 minute (longer if necessary) to mix and dissolve it.

[0155] 5. The desired execution time of 1 minute for dissolving the detergent was entered into the controller.

[0156] 6. To minimize differences in exposure time to the detergent system, the swatches were quickly placed into their respective pots in the order from left to right.

[0157] 7. Enter the washing time as in step 5, and start stirring immediately after adding the swatch.

[0158] 8. At the end of the run, quickly remove the swatches from the pots using tweezers, from left to right, and rinse them in 1 liter of cold 5-grain (gpg) water. Use one container of cold rinse water for each pot. Remove the swatches from the cold water and rinse them further with cold tap water using a strainer or colander in the sink.

[0159] 9. After rinsing with cold tap water, squeeze out any excess water from the swatch. Repeat the rinsing and squeezing process two more times.

[0160] 10. Air-dry the swatch on a Wypall paper towel on the lab bench.

[0161] 11. Next, read the swatch with HunterLab Color Quest and calculate the stain removal rate from the difference between the initial (pre-wash) L value and the final L value (post-wash). For details, please refer to the HunterLab procedure.

[0162] Figure 1 shows the percentage of lipstick removed. This graph shows the percentage of lipstick removal by the evaluated formulations. A higher value indicates that more lipstick was removed. Beneficially, the evaluated formulations containing branched polyamine surfactant (Amine 739) provided 96.9% stain removal, performing at least as well as 450 ppm of Tergitol NP-9 (NPE) and outperforming alkoxylate surfactants and caustic formulations (negative control with Builder C alone).

[0163] Example 2 Further tergometer tests were conducted to measure the cleaning power of various evaluated laundry formulations against lipstick stains. The caustic alkali detergent formulations shown in Figure 2 were evaluated using the procedure described in Example 1. Linear polyamines (Amine 736), branched polyamines (Amine 739), and various conventional surfactants were compared. The results are shown in Figure 2. Branched polyamines were superior to linear polyamines and other evaluated amine-containing surfactants in removing lipstick stains.

[0164] Example 3 Further tergometer tests were conducted to measure the cleaning power of various evaluated laundry formulations against lipstick stains. The detergent formulations shown in Figure 3 were evaluated using the procedure described in Example 1. The results are shown in Figure 3, where branched polyamine (Amine 739) was superior to linear polyamine (Amine 736) in removing lipstick stains.

[0165] Example 4 Further tergometer tests were performed to measure the cleaning power of various evaluated laundry formulations against lip makeup stains. The detergent formulations shown in Figure 4 were evaluated using the procedure described in Example 1. The detergent formulations included a caustic builder and were combined with either a control detergent or a variety of linear or branched polyamines according to embodiments of the present disclosure. The results are shown in Figure 4. Branched polyamines perform at least similarly to linear polyamines for laundry applications, with the exception of shorter-chain polyamines (C6, C8) which do not perform better than caustic alkali control. Overall, the data show improved performance of branched polyamines with chain lengths of at least C8, preferably at least C9 or at least C12.

[0166] Example 5 Further tergometer testing was used to measure the cleaning power of various evaluated laundry formulations against lip makeup stains. Polyamines with longer branched chain lengths were evaluated compared to Example 5. The detergent formulations shown in Figure 5 were evaluated using the procedure described in Example 1 (Cover Girl #435 was washed on a cotton label lipstick at 120°F for 10 minutes). The detergent formulations contained a caustic builder and were combined with either a control detergent or one of the various branched polyamines according to embodiments of the present disclosure. The results are shown in Figure 5, where the C18-chain length branched polyamine (Amine 2) provided better stain removal for laundry applications compared to the commercial control.
