Description

[Technical field]

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This application claims priority under 35 U.S.C. § 119 to U.S. Provisional Application No. 62 / 595,686, filed November 7, 2017, which is incorporated herein by reference in its entirety.

[0002] The present invention relates to a method for cleaning waxy, oily, and / or greasy stains, including lip cosmetic stains such as lipstick and lip gloss. In particular, the removal of lip cosmetic stains, including lipstick and lip gloss stains, in laundry and other hard surface cleaning applications is disclosed through the application of solid and / or liquid cleaning compositions comprising branched polypolyamines, i.e., C6-C20, C8-C20, C10-C20, C10-C18, or C10-C12 branched polypolyamines having 1-5 nitrogens, with or without an alkaline source and preferably an additional surfactant. [Background technology]

[0003] Various fabric substrates, textiles, and laundry are often stained by lip makeup stains that are rubbed off from people's lips onto textiles and laundry. Lip makeup stains are typically very difficult to remove due to their waxy, oily, and / or greasy consistency. Recently, lip makeup stains have become even more difficult to remove as a result of advances in the lip makeup industry, such as new "long-lasting" lipsticks. In the past, such fabric substrates have undergone various pretreatment and / or cleaning processes, depending on the particular method used in trying to remove such difficult stains. Prior to the traditional laundry wash cycle, pretreatment or soaking was used to remove lip makeup stains or to loosen the stains at the end. Often, these pretreatments require the substrate to be soaked in a cleaning composition to adequately contact the stain. Additional processes include, for example, re-washing the substrate, manually scrubbing the substrate, and / or adding additional time to the washing machine wash cycle to remove such stains. There is a need for improved stain removal for lip cosmetics. Summary of the Invention [Problem to be solved by the invention]

[0004] It is therefore an object 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 object is to provide improved laundry wash cycle performance for removing such lip makeup stains.

[0006] A further object is to provide a cleaning composition that does not require the use of a pretreatment step to soak lip makeup stains on fabric substrates.

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

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

[0009] The advantage of the composition and method is that the formulations containing multiple surfactants provide synergistic cleaning power for lip cosmetic stains in laundry applications. The solid and / or liquid alkaline cleaning compositions include branched polypolyamines, i.e., C6-C20 polypolyamines having 1-5 nitrogens, preferably C8-C20, C8-C18, or C10-C18 polypolyamines having 1-5 nitrogens. The cleaning compositions can include or exclude an alkaline source. The preferred alkaline cleaning compositions include hydroxide-based, carbonate-based, and / or silicate-based detergents that include a surfactant and at least one branched polypolyamine.

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

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

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

[0019] In order to make the present invention easier to understand, certain terms are defined first.Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which the present invention relates.Many methods and materials similar, modified, or equivalent to those described herein can be used to implement the present invention without undue experimentation, and preferred materials and methods are described herein.In describing and claiming the present invention, the following terminology is used according to the definitions described below.

[0020] The term "about" as used herein refers to variations in numerical quantities that may occur, for example, due to typical measuring and liquid handling procedures used in the real world to make concentrates or use solutions, inadvertent errors in those procedures, differences in manufacture, source, or purity of ingredients used to make the composition or carry out the method, etc. The term "about" also encompasses amounts that differ due to different equilibrium conditions for a composition resulting from a particular initial mixture. Whether or not modified by the term "about," the claims include the equivalent of the amount.

[0021] The terms "actives" or "percent actives" or "percent actives by weight" or "actives concentration" are used interchangeably herein and refer to the concentration of ingredients involved in cleaning expressed as a percentage minus inactive ingredients such as water or salt.

[0022] 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).

[0062] Nonionic Surfactants 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, which is generally ethylene oxide or its polyhydration product, polyethylene glycol. In fact, any hydrophobic compound having a hydroxyl, carboxyl, amino, or amide group with a reactive hydrogen atom can be condensed with ethylene oxide, or its polyhydration adducts, or its mixtures with alkoxylene, such as propylene oxide, to form a nonionic surfactant. The length of the hydrophilic polyoxyalkylene moiety condensed with any particular hydrophobic compound can be easily adjusted to produce a water-dispersible or water-soluble compound with the desired degree of balance between hydrophilic and hydrophobic properties. Useful nonionic surfactants include block polyoxypropylene-polyoxyethylene polymer compounds based on propylene glycol, ethylene glycol, glycerol, trimethylolpropane, and ethylenediamine as the initiator reactive hydrogen compound. Examples of polymeric compounds made from sequential propoxylation and ethoxylation of initiators are commercially available from BASF Corp. One class of compounds are difunctional (two reactive hydrogens) compounds formed by condensing ethylene oxide with a hydrophobic base formed by the addition of propylene oxide to two hydroxyl groups of propylene glycol. This hydrophobic portion of the molecule has a molecular weight of about 1,000 to about 4,000. Ethylene oxide is then added to sandwich this hydrophobe between hydrophilic groups, controlled by length 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 to constitute about 10% to about 80% by weight of the molecule.

[0063] Condensation products of one mole of alkylphenols, in which the alkyl chain, of straight or branched configuration, or of single or double alkyl constituents, contains from about 8 to about 18 carbon atoms, with from about 3 to about 50 moles of ethylene oxide. The alkyl groups may be represented, for example, by diisobutylene, di-amyl, 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 available under the trade names Igepal® manufactured by Rhone-Poulenc, and Triton® manufactured by Union Carbide.

[0064] A condensation product of one mole of a saturated or unsaturated straight or branched chain alcohol having from about 6 to about 24 carbon atoms with from about 3 to about 50 moles of ethylene oxide. The alcohol portion may consist of a mixture of alcohols within the carbon range set forth above, or may consist 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™, Dehydol™ from BASF, Neodol™ from Shell Chemical Co., and Alfonic™ from Vista Chemical Co.

[0065] The condensation product of one mole of a saturated or unsaturated straight or branched chain carboxylic acid having from about 8 to about 18 carbon atoms with from about 6 to about 50 moles of ethylene oxide. The acid portion may consist of a mixture of acids within the carbon atom range defined above, or may consist of an acid having a specific number of carbon atoms within this range. Examples of commercial compounds of this chemistry are available under the trade names Disponil or Agnique manufactured by BASF, and Lipopeg™ manufactured by Lipo Chemicals, Inc.

[0066] In addition to ethoxylated carboxylic acids, commonly referred to as polyethylene glycol esters, glycerides, glycerin, and other alkanoic acid esters formed by reaction with polyhydric (saccharide or sorbitan / sorbitol) alcohols have applications herein for specialized embodiments, particularly indirect food additive applications. All of these ester moieties have one or more reactive hydrogen sites on the molecule that can be subjected to further acylation or ethylene oxide (alkoxide) addition to control the hydrophilicity of these materials. Care must be taken when adding these fatty esters or acylated carbohydrates to compositions of the present invention containing amylase and / or lipase enzymes due to possible incompatibilities.

[0067] Examples of non-ionic low foaming surfactants include: Compounds from (1) that have been modified, essentially inverted, by adding ethylene oxide to ethylene glycol to provide a hydrophile of a specified molecular weight; 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 hydrophile comprises 10% to about 80% by weight of the final molecule. These inverted Pluronics™ are manufactured by BASF Corporation under the trademark 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 about 2,100 to about 6,700, and the central hydrophile comprises 10% to about 80% by weight of the final molecule.

[0068] Compounds modified by "capping" or "end-blocking" the terminal hydroxy group(s) (of a multifunctional moiety) to reduce foaming due to reaction with hydrophobic small molecules such as propylene oxide, butylene oxide, benzyl chloride, and short chain fatty acids, alcohols, or alkyl halides containing 1-5 carbon atoms, and mixtures thereof. Also included are reactants such as thionyl chloride that convert the terminal hydroxy group to a chloride group. Such modifications to the terminal hydroxy group may result in all-block, block-heteric, heteric-block, or all-heteric nonionic materials.

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

[0079] Fatty acid amide surfactants suitable for use in the present compositions include those having the formula: RCON(R), where R is an alkyl group containing 7 to 21 carbon atoms and each R is independently hydrogen, C1-C4 alkyl, C1-C4 hydroxyalkyl, or --(CHO).

[0080] A useful class of nonionic surfactants includes the class defined as alkoxylated amine or, most specifically, alcohol alkoxylated / aminated / alkoxylated surfactants. These nonionic surfactants can be at least partially represented by the general formula: 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, where R 20is an alkyl, alkenyl or other aliphatic group, or an alkyl-aryl group of 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.

These compounds are commercially represented by the line of products sold by Huntsman Chemicals as nonionic surfactants. Preferred chemicals in this class include Surfonic™ PEA 25 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 article, Nonionic Surfactants, edited by Schick, MJ, Vol. 1 of the Surfactant Science Series, Marcel Dekker, Inc., New York, 1983, is an excellent reference for the wide range of nonionic compounds commonly used in the practice of the present invention. A typical list of nonionic classes and species of these surfactants is given in U.S. Patent No. 3,929,678, issued to Laughlin and Heuring on December 30, 1975. Further examples are given in "Surface Active Agents and Detergents" (Vol. I and Vol. II, Schwartz, Perry and Berch).

[0082] Semi-polar nonionic surfactants Semi-polar nonionic surfactants are another class of nonionic surfactants that are useful in the compositions of the present invention.In general, semi-polar nonionics are high 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 cleaning methods, semi-polar nonionics have immediate practical application.Semi-polar nonionic surfactants include amine oxides, phosphine oxides, sulfoxides and their alkoxylated derivatives.

[0091] Anionic Surfactants Surfactants classified as anionic because the charge on the hydrophobe is negative, or surfactants in which the hydrophobic portion of the molecule does not carry a charge unless the pH is raised above neutral (e.g., carboxylic acids), are also useful in the present invention. Carboxylate, sulfonate, sulfate, and phosphate are polar (hydrophilic) solubilizing groups found in anionic surfactants. Of the cations (counterions) associated with these polar groups, sodium, lithium, and potassium impart water solubility, ammonium and substituted ammonium ions provide both water and oil solubility, and calcium, barium, and magnesium promote oil solubility. As one skilled in the art will appreciate, anionic materials are excellent detersive surfactants and are therefore preferred additives to heavy duty detergent compositions.

[0092] Anionic sulfate surfactants suitable 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 oleyl glycerol sulfates, alkylphenol ethylene oxide ether sulfates, C5-C 17Included are acyl-N-(C1-C4 alkyl) and -N-(C1-C2 hydroxyalkyl) glucamine sulfates, as well as sulfates of alkyl polysaccharides, such as the sulfates of alkyl polyglucosides. Also included are alkyl sulfates, alkyl poly(ethyleneoxy) ether sulfates, and aromatic poly(ethyleneoxy) sulfates, such as the sulfate or condensation products of ethylene oxide with nonylphenol (usually having 1 to 6 oxyethylene groups per molecule).

[0093] Anionic sulfonate surfactants suitable for use in the present compositions also include alkyl sulfonates, linear and branched primary and secondary alkyl sulfonates, and aromatic sulfonates with or without substituents.

[0094] Anionic carboxylate surfactants suitable for use in the present compositions include carboxylic acids (and salts), such as alkanoic acids (and alkanoates), ester carboxylic acids (e.g., 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 (e.g., alkyl carboxyls). Secondary carboxylates useful in the present compositions include those that contain a carboxyl unit connected to a secondary carbon. The secondary carbon may be in a ring structure, such as in p-octyl benzoic acid, or in alkyl substituted cyclohexyl carboxylates. Secondary carboxylate surfactants typically do not contain ether linkages, ester linkages, and hydroxyl groups. In addition, they typically lack a nitrogen atom in the head group (amphiphilic portion). 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 acylamino acids (and salts), such as, for example, acyl glutamates, acyl peptides, sarcosinates (eg, N-acylsarcosinates), taurates (eg, N-acyltaurates and fatty acid amides of methyl tauride).

[0095] Suitable anionic surfactants include alkyl or alkylaryl ethoxy carboxylates of the formula: RO-(CH2CH2O) n (CH2) m -CO2X(3) In the formula, R is C8 to C 22 is an alkyl group, or [ka] and R 1 is C4~C 16In some embodiments, R is an alkyl group, 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, 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 a C8 to C 16 In some embodiments, R is an alkyl group. 12 ~C 14 It is an alkyl group, n is 4, and m is 1.

[0096] In other embodiments, R is [ka] and R 1 is C6~C 12 In still other embodiments, R 1 is a C9 alkyl group, n is 10, and m is 1.

[0097] Such alkyl and alkylaryl ethoxy carboxylates are commercially available. These ethoxy carboxylates are typically available in the acid form, which can be readily converted to the 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 products Sandopan® DTC, C 13 Alkylpolyethoxy(7) carboxylic acids are also available from Clariant.

[0098] Cationic Surfactants A surface active material is classified as cationic if the charge on the hydrotrope portion of the molecule is positive. Surfactants in which the hydrotrope does not carry a charge unless the pH is lowered to near neutral or below, but then is cationic (e.g., alkylamines), are also included in this group. In theory, cationic surfactants can be synthesized from any combination of elements that contain 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, probably because the synthetic route to nitrogen cationic surfactants is simple and easy, resulting in high product yields, which makes nitrogen cationic surfactants less expensive.

[0099] Cationic surfactants preferably refer to compounds that contain at least one long carbon chain hydrophobic group and at least one positively charged nitrogen. The long carbon chain group may be directly attached to the nitrogen atom by simple substitution, or more preferably, indirectly attached by a bridging functional group(s) in so-called interrupted alkylamines and amidoamines. Such functional groups can make the molecule more hydrophilic and / or more water-dispersible, more easily dissolved in water by co-surfactant mixtures, and / or water-soluble. To increase 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. Furthermore, the nitrogen can be part of a branched or straight chain moiety with various degrees of unsaturation, or part of a saturated or unsaturated heterocyclic ring. In addition, cationic surfactants may contain complex bonds with two or more cationic nitrogen atoms.

[0100] Surfactant compounds classified as amine oxides, amphoterics, and zwitterions are themselves generally cationic in solutions at near-neutral to acidic pH and overlap 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 the bulk commercial cationic surfactants can be subdivided into four main classes and additional subgroups known to those skilled in the art and 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 quaternaries such as alkylbenzyldimethylammonium salts, alkylbenzene salts, heterocyclic ammonium salts, tetraalkylammonium salts, etc. Cationic surfactants are known to have a variety of properties that may be beneficial in the present compositions. These desirable properties may include detergency in compositions below neutral pH, antimicrobial efficacy, thickening or gelling in conjunction with other agents, etc.

[0102] Cationic surfactants useful 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 linear or branched alkyl or alkenyl group, optionally substituted with up to three phenyl or hydroxy groups, and up to four of the following structures: [ka] or an organic group optionally interrupted by an isomer or mixture of these structures, which contains from about 8 to 22 carbon atoms. 1The group may additionally contain up to 12 ethoxy groups. m is a number from 1 to 3. Preferably, there is not more than one R 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 is an alkyl or hydroxyalkyl group containing 1 to 4 carbon atoms or a benzyl group, and not more than one R 2 is benzyl, and x is a number from 0 to 11, preferably from 0 to 6. The remainder of any carbon atom positions on the Y group are occupied by hydrogen.

[0103] Y is, but is not limited to, [ka] or mixtures thereof. Preferably, L is 1 or 2, and the Y group is R 1 having 1 to about 22 carbon atoms and 2 free carbon single bonds when L is 2. 1 and R 2 Z is a water-soluble anion such as a halide, sulfate, methylsulfate, hydroxide, or nitrate, with chloride, bromide, iodide, sulfate, or methylsulfate being preferred in numbers that provide electrical neutrality of the cationic component.

[0104] Amphoteric surfactants Amphoteric or ampholytic 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 the negative charge.

[0105] Amphoteric surfactants can be broadly described as derivatives of aliphatic secondary and tertiary amines, where the aliphatic radicals can be straight or branched, one of the aliphatic substituents contains about 8-18 carbon atoms, and one contains an anionic water-solubilizing 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), the entire contents of which are incorporated herein by reference. 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 can 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-alkylhydroxyethyl imidazoline is synthesized by condensation and ring closure of 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 opening of the imidazoline ring by alkylation. During alkylation, one or two carboxy-alkyl groups react to form ether bonds with tertiary amines and different alkylating agents to produce different tertiary amines.

[0107] Long chain imidazole derivatives having use in the present invention generally have the 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, typically sodium, for neutralizing the charge of the anion. Commercially well-known imidazoline-derived amphoteric compounds that can be used in the composition include, for example, cocoamphopropionate, cocoamphocarboxy-propionate, cocoamphoglycinate, cocoamphocarboxy-glycinate, cocoamphopropyl-sulfonate, and cocoamphocarboxy-propionic acid. Amphocarboxylic acids can be generated from aliphatic imidazolines, where the dicarboxylic acid functional group of the amphodicarboxylic acid is diacetic acid and / or dipropionic acid.

[0108] The carboxymethylated compounds (glycinates) described herein above are often referred to as betaines, which are a special class of amphoteric compounds described herein below in the section entitled Zwitterionic Surfactants.

[0109] Long chain N-alkyl amino acids are easily prepared by the reaction RNH2, where R is C8-C 18 They are fatty amines with linear or branched 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. 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 ampholytes that are applicable to the present invention include alkyl β-amino dipropionates, RN(C2H4COOM)2 and RNHC2H4COOM. In embodiments, R can be an acyclic hydrophobic group containing about 8 to about 18 carbon atoms, and M is a cation to neutralize 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 combinations thereof, and an aliphatic substituent of about 8 to 18 (e.g., 12) carbon atoms. Such surfactants can also be considered alkyl amphodicarboxylic acids. These 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 combinations thereof, and an aliphatic substituent of about 8 to 18 (e.g., 12) carbon atoms. Such surfactants can also be considered alkyl amphodicarboxylic acids. 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 suitable amphoteric surfactant, and is commercially available under the trade name Miranol™ FBS from Rhodia Inc. (Cranbury, NJ). 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, NJ).

[0111] A representative list of amphoteric classes 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" (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 can 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 sometimes sulfonium or phosphonium ion, a negatively charged carboxyl group, and an alkyl group. Zwitterionic compounds generally contain cationic and anionic groups that ionize to about the same extent in the isoelectric region of the molecule, which can create a strong "inner salt" attraction between the positive-negative charge centers. Examples of such zwitterionic synthetic surfactants include derivatives of aliphatic quaternary ammonium, phosphonium, and sulfonium compounds in which the aliphatic group can be straight or branched chain, and one of the aliphatic substituents contains 8 to 18 carbon atoms and one contains an anionic water-solubilizing group, such as carboxy, sulfonate, sulfate, phosphate, or phosphonate.

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

[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-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-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-hydroxy-pentane-1-sulfate. The alkyl groups contained in the detergent surfactants can be linear or branched and saturated or unsaturated.

[0115] Zwitterionic surfactants suitable for use in the present compositions include betaines of the general structure: [ka] These surfactant betaines typically do not exhibit strong cationic or anionic properties at the extremes of pH, nor do they exhibit low water solubility in the isoelectric range. Unlike "external" quaternary ammonium salts, betaines are compatible with anionic materials. Examples of suitable betaines include coconut acylamidopropyl dimethyl betaine, hexadecyl dimethyl betaine, C 12~14 Acylamidopropyl betaine, C 8~14 Acylamidohexyl diethyl betaine, 4-C 14~16 Acylmethylamidodiethylammonio-1-carboxybutane, C 16~18 Acylamide dimethyl betaine, C 12~16 Acylamide pentane diethyl betaine, and C 12~16 Acylmethylamidodimethylbetaine is an example.

[0116] Sultaines useful in the present invention have the formula (R(R 1 )2N + R 2 SO 3- where R is a C6-C 18 is a hydrocarbyl group, and each R 1 are typically independently C1-C3 alkyl, e.g., methyl, and R 2 is a C1-C6 hydrocarbyl group, for example a C1-C3 alkylene or hydroxyalkylene group.

[0117] A representative listing of zwitterionic classes and species of these surfactants is found in U.S. Patent No. 3,929,678, issued Dec. 30, 1975 to Laughlin and Heuring. Further examples are found in "Surface Active Agents and Detergents" (Vol. I and II by Schwartz, Perry and Berch). Each of these references is incorporated herein in its entirety.

[0118] Defoamer The composition and method of the present invention can optionally include antifoaming agent.Antifoaming agent can be particularly suitable for the embodiment that includes foaming surfactant, such as anionic surfactant.Generally, antifoaming agents that can be used include silica and silicone;fatty acid or ester;alcohol;sulfate or sulfonate;amine or amide;halogen compound, such as fluorochlorohydrocarbon;vegetable oil, wax, mineral oil, and their sulfonated or sulfated derivatives;fatty acid and / or their soap, such as alkali, alkaline earth metal soap;and phosphate and phosphate ester, such as alkyl and alkaline diphosphate, and especially tributyl phosphate;and mixtures thereof.

[0119] In some embodiments, the composition may contain antifoaming or defoaming agents that are food grade quality, considering the application of the method. For this purpose, one of the more effective antifoaming agents includes silicone. Silicones such as dimethyl silicone, glycol polysiloxane, methylphenol polysiloxane, trialkyl or tetraalkyl silane, hydrophobic silica defoamer, and mixtures thereof can all be used for defoaming applications. Publicly available commercial defoamers include ARDEFOAM™ from Armour Industrial Chemical Company, which is a bonded silicone in 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 type silicones, among others.

[0120] enzyme In some embodiments, the composition may further comprise an enzyme. Preferably, in cleaning compositions that do not include an alkaline source, the enzyme and water make up 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 and render 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 composition containing the enzyme must be such that the enzyme component remains stable and is not denatured. Such a pH may be at or near a neutral pH, or about 7-8. For certain enzymes, such a pH may be about 7 and about 11, or may be about 7 to about 11. As those skilled in the art will recognize, there is a difference between a stable enzyme and an active enzyme. For example, an enzyme may be formulated into a composition at pH 6 and considered stable but not active, but when the enzyme is then used in an alkaline composition / application that changes the pH of the composition (e.g., to 6-11), the pH is changed to a higher "ideal" pH (e.g., pH 11) and the enzyme becomes active.

[0122] Amylase is an example of an enzyme that is useful in cleaning compositions. Examples of amylases that can be used are alpha-amylases from Bacillus licheniformis, B.amyloliquiefaciens or B.stearothermophilus, and their improved developed forms for use in cleaning and cleaning compositions. Novozymes and Genencor sell commercial alpha-amylases from one or all of the above bacterial species. Novozymes also offers alpha-amylases from Aspergillus niger and A.oryzae.

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

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

[0125] Mixtures of different enzymes may be incorporated into the cleaning composition. Although various specific enzymes have been described, it should be understood that any enzyme, such as a protease, capable of imparting the desired proteolytic activity to the composition may be used. The compositions of the present invention include from about 0% to about 25% by weight of enzyme, from about 0.0005% to about 15% by weight of enzyme, from about 0.001% to about 10% by weight of enzyme, from about 0.001% to about 5% by weight of enzyme, from about 0.001% to about 1% by weight of enzyme. Additionally, without being limited to the present invention, all ranges recited are inclusive of the numbers defining the range and include each integer within the defined range.

[0126] Kieran In some embodiments, the composition may further comprise a chelant. As used herein, chelation refers to the binding or complexation of a bidentate or polydentate ligand. These ligands are often organic compounds and are called chelant, chelator, chelating agent, and / or sequestering agent. Chelants form multiple bonds with a single metal ion. Chelant is a chemical that forms soluble complex molecules with certain metal ions, inactivating those ions so that they cannot normally react with other elements or ions to produce precipitates or scale. The ligand forms a chelate complex with the substrate. The term is for complexes in which the 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, and mixtures thereof. Particularly useful amino carboxylic acid materials that contain little or 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 with a carboxylic acid substituent.

[0128] Other chelants include aminocarboxylates, including ethylenediaminetetra-acetate, N-hydroxyethylethylenediaminetriacetate, nitrilo-triacetate, ethylenediaminetetraprop-prionate, triethylenetetraaminehexaacetate, diethylenetriaminepentaacetate, and ethanoldi-glycine, alkali metal, ammonium, and substituted ammonium salts thereof, and mixtures thereof. Suitable chelants include aminocarboxylates, aminophosphonates, polyfunctionally substituted aromatic chelants, and mixtures thereof. Exemplary chelants include amino acid-based chelants, and preferably citric acid, tartaric acid, and glutamic acid-N,N-diacetic acid and derivatives, and / or phosphonate-based chelants.

[0129] Other chelants include homopolymers and copolymers of polycarboxylic acids and their partially or fully neutralized salts, as well as monomeric polycarboxylic and hydroxycarboxylic acids and their salts. Preferred salts of the above-mentioned compounds are the ammonium and / or alkali metal salts, i.e., lithium, sodium, and potassium salts, and particularly preferred salts are the sodium salts, such as sodium sulfate.

[0130] Other chelants include polycarboxylic acid polymers. Representative polycarboxylic acid polymers suitable for the rinse composition include, inter alia, amino carboxylic acids, water-soluble acrylic polymers, polymaleic acid homopolymers, maleic acid polymers, in order to adjust the rinse solution under end-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 metal (e.g., sodium or potassium) or ammonium salts, can also be used.

[0131] Additionally, phosphonate or phosphonate sequestering agents can also be used. In some embodiments, phosphonate and / or phosphonate sequestering agents can be used alone without the 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.

[0132] Water Control Polymer In one embodiment, the composition optionally includes water conditioning polymer(s). In some aspects, the water conditioning polymer is a secondary builder or scale inhibitor for 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).

[0133] In a further aspect, the water conditioning polymer can include polycarboxylates or related copolymers. Polycarboxylates refer to compounds having multiple carboxylate groups. A variety of such polycarboxylate polymers and copolymers are known, described in patent and other literature, and commercially available. Exemplary polycarboxylates that can be used as builders and / or water conditioning polymers include those having pendant carboxylates (-CO2 -) groups, such as, but 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 polyacrylamides, hydrolyzed polymethacrylamides, hydrolyzed polyamide-methacrylamide copolymers, hydrolyzed polyacrylonitrile, hydrolyzed polymethacrylonitrile, and hydrolyzed acrylonitrile-methacrylonitrile copolymers. In a further aspect, polycarboxylates that can be used as builder and / or water conditioning polymers include, but are not limited to, polyacrylate homopolymers and copolymers; polyacrylates; polymethacrylates; non-carboxylated materials, such as copolymers of polyolefins and polymaleic acid, such as hydrogenated olefin and hydrogenated maleic acid copolymers; and all derivatives and salts thereof. Further description of exemplary polycarboxylates and polyacrylates is provided in US Pat. Nos. 7,537,705 and 3,887,806.

[0134] In a further aspect, the water conditioning polymer can include polyacrylate or related copolymers.Suitable polyacrylates, homopolymers and copolymers of polyacrylates, polyolefins and polymaleates according to the present invention can include organic compounds, such as both polymeric and small molecule agents, such as polyanionic compositions, such as polyacrylic acid compounds.Polymeric agents usually include polyanionic compositions, such as polyacrylic acid compounds.For example, exemplary commercially available acrylic acid type polymers include acrylic acid polymers, methacrylic acid polymers, acrylic acid-methacrylic acid copolymers, and the water-soluble salts of the 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 polyacrylamides, hydrolyzed polymethacrylamides, 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, include the water-soluble salts or partial salts of these polymers, such as the respective alkali metal (e.g., sodium or potassium) or ammonium salts thereof, and the like.

[0136] Cleaning Method The cleaning method is particularly suited to removing lip makeup stains. Without wishing to be bound by scientific theories, it is believed that the hydrophobic portion of lip makeup stains makes them particularly difficult to remove from the substrate on which they are soiled. The hydrophobic portion of the lip cosmetic can be an oil, a viscous solid, or a wax, depending on the consistency of the final product. For example, lip glosses that are rolled on the lips tend to be more viscous liquid than lip glosses that are applied using fingertips. Naturally, roll-on lip glosses are likely to have more oil and a higher amount of solids or wax than fingertip lip glosses. The hydrophobic component of the lip cosmetic can be natural or synthetic.The following is a list of non-limiting examples 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, ouricury wax, oxidized beeswax, oxidized microcrystalline wax, ozokerite, palm kernel wax, paraffin, PEG-6 beeswax, PEG-8 beeswax, PEG-12 beeswax, PEG-20 beeswax, PEG-12 carnauba, petrolatum, yellow petrolatum, potassium oxidized microcrystalline wax, rice (Oryza sativa) wax, sesame (Sesamum indicum) oil, shea butter (Butyrospermum parkii), shellac wax, brewers grain wax, stearic acid, sulfurized jojoba oil, synthetic beeswax, synthetic candelilla wax, synthetic carnauba, 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 are capable of removing lip cosmetic stains having the hydrophobic and other materials listed above, 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 any type of fabric substrate, such as textiles and other hard surfaces. The cleaning method includes contacting the fabric substrate or other hard surface from which lip cosmetic stains need to be removed, 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 dipping, spraying, dripping, wiping, etc., can be used to contact the fabric substrate or hard surface with the alkaline cleaning composition. As included within the scope of the described contact, the fabric substrate and / or hard surface can also be dipped with the alkaline composition, including a pretreatment or cleaning cycle. As a result of the contacting step, the surface is cleaned and the stains are removed.

[0139] In one aspect, the surface is a fabric substrate, such as laundry. Exemplary laundry includes, for example, items or articles that are washed in a washing machine. In general, laundry refers to any item or article made from or including textile materials, woven fabrics, nonwoven fabrics, and knitted textiles. Textile materials may 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. Exemplary treated fibers include those that are flame retardant treated. It should be understood that the term "linen" is often used to describe certain types of laundry items, such as bed sheets, pillowcases, towels, and the like. The present invention additionally provides compositions and methods for treating non-laundry articles and surfaces, including hard surfaces. The washing of textiles and laundry described herein may be manual washing. In another aspect, the substrate is washed in a washing machine.

[0140] For cleaning, soaking (or pre-treatment) and / or other hard surface treatment applications, the branched polyamines can be added to the cleaning composition in the use solution. Alternatively, a fully formulated cleaning composition can be provided. Use in laundry applications can include applying the pre-treatment concentrate as a spray, as a mist onto the substrate in need of treatment. Contact times can vary from a few seconds to a few minutes. In other embodiments, a lower concentration of the cleaning composition can be used for pre-soak applications. In such embodiments, contact times can vary from a few minutes to a few hours.

[0141] The method can also include a first step of diluting and / or making an aqueous use solution (e.g., from a solid). An exemplary dilution step includes contacting a liquid and / or solid composition with water. The compositions of the present invention include concentrate compositions and use compositions. For example, a concentrate composition can be diluted, for example, with water to form a use composition. In one embodiment, a concentrate composition can be diluted into a use solution before application to an object. For economic reasons, a concentrate is sold and the end user can dilute the concentrate into a use solution with water or an aqueous diluent. The level of active ingredient in a concentrate composition depends on the intended dilution factor and the desired activity of the active ingredient of the concentrate. Generally, a dilution of about 1 fluid ounce to about 10 gallons of water to about 10 fluid ounces to about 1 gallon of water is used for aqueous compositions. In some embodiments, when used in laundry applications, the concentrated composition can be diluted at a dilution ratio of about 0.1 g / L to about 100 g / L of concentrate relative to the diluent, about 0.5 g / L to about 10.0 g / L of concentrate relative to the diluent, about 1.0 g / L to about 4.0 g / L of concentrate relative to the diluent, or about 1.0 g / L to about 2.0 g / L of concentrate relative to the diluent. In other embodiments, the use composition can include 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] The alkaline cleaning composition may be provided at a ready-to-use actives level that provides the desired amount of actives of the components of the composition, and / or in a concentrated composition. In one embodiment, the branched polyamine and / or additional surfactant are provided at a concentration of about 100 ppm to about 10,000 ppm in the use solution, about 100 ppm to about 800 ppm in the use solution, about 100 ppm to about 400 ppm in the use solution, or about 200 ppm to about 300 ppm in the use solution.

[0143] In one embodiment, the alkaline cleaning composition, in a use solution, contacts the textile substrate and / or other hard surface in need of cleaning and has a pH of from about 7.5 to about 13.5.

[0144] In one embodiment, the alkaline cleaning composition is contacted with the textile substrate and / or other hard surface for a time sufficient to remove soil, e.g., from a few seconds to a few hours. In some embodiments, the cleaning composition can be used in either a wash or presoak situation, and the article is contacted with the composition of the present invention for a time effective to clean the article at a use 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] The alkaline cleaning composition can be used alone to treat an article, such as a textile, or can be used together with a conventional detergent suitable for the article to be treated. The composition can be used together with a conventional detergent in various ways, for example, the composition can be combined with a conventional detergent. In other embodiments, the composition can be used as a separate additive from a conventional detergent to treat the article. When used as a separate additive, the composition can be contacted with the article to be treated at any time. For example, the composition can be contacted with the article before, after, or substantially simultaneously with contacting the article with the selected detergent.

[0146] All publications and patent applications in this specification are indicative of the level of those skilled in the art to which this invention pertains. All publications and patent applications are herein incorporated by reference to the same extent as if each individual publication or patent application was specifically and individually indicated to be incorporated by reference.

[0149] Example 1 A Tergometer was used to measure the cleaning power of various evaluated laundry formulations against lip cosmetic stains. The detergent formulations shown in Figure 1 were evaluated using a caustic-based detergent composition containing a surfactant utilizing a branched polyamine (Amine 739) compared to a conventional alkoxylate surfactant at a surfactant level of 450 ppm.

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

[0151] procedure: 1. Unwashed swatches of the lot number being used in the test are read on a HunterLab Color Quest spectrophotometer to determine the average initial (pre-wash) L value.

[0152] 2. The desired wash temperature of 120°F is then programmed into the Tergotometer and the water bath is heated to that temperature.

[0153] 3.1 liters of 5 grain (gpg) water was added to each tergotometer pot and equilibrated to 120°F.

[0154] 4. The detergent system is weighed out and placed into the tergometer pot. The detergent system is stirred for 30 seconds to 1 minute (longer if necessary) to mix and dissolve.

[0155] 5. A desired run time of 1 minute for the detergent to dissolve was entered into the controller.

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

[0157] 7. Enter the wash time as in step 5 and start agitation immediately after loading the swatch.

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

[0159] 9. Rinse under cold tap water and then squeeze excess water from the swatch. Repeat the rinsing and squeezing process two more times.

[0160] 10. Air dry the swatches on Wypall paper towels on the lab bench.

[0161] 11. The swatches are then read on the HunterLab Color Quest and the percent stain removal is calculated from the difference between the initial (before washing) L value and the final L value (after washing). Please refer to HunterLab's procedure for details.

[0162] The percentage of lipstick removed is shown in Figure 1, which is a graph showing the percentage of lipstick removal by the evaluated formulations. Higher values ​​indicate more lipstick was removed. Advantageously, the evaluated formulation containing a branched polyamine surfactant (Amine 739) provided 96.9% stain removal, performing at least as well as 450 ppm Tergitol NP-9 (NPE) and outperforming the alkoxylate surfactant and caustic formulation (Builder C alone negative control).

[0163] Example 2 Further tergometer testing measured the cleaning power of various evaluated laundry formulations against lip cosmetic stains. The caustic based detergent formulations shown in Figure 2 were evaluated using the procedure described in Example 1. A linear polyamine (Amine 736), a branched polyamine (Amine 739), and various conventional surfactants were compared. The results are shown in Figure 2. The branched polyamine outperformed the linear polyamine and the other evaluated amine-containing surfactants in removing lipstick stains.

[0164] Example 3 Further tergometer testing measured the cleaning power of the various evaluated laundry formulations against lip cosmetic 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 the branched polyamine (Amine 739) outperformed the linear polyamine (Amine 736) for lipstick stain removal.

[0165] Example 4 Further tergometer testing measured the cleaning power of various evaluated laundry formulations against lip cosmetic stains. The detergent formulations shown in Figure 4 were evaluated using the procedure described in Example 1. The detergent formulations contained caustic builders and were combined with either a control detergent or various linear or branched polyamines according to embodiments of the present disclosure. The results are shown in Figure 4. The branched polyamines perform at least as well as linear polyamines in laundry applications, except for the shorter chain polyamines (C6, C8) which do not perform better than the caustic control. Overall, the data shows improved performance of branched polyamines with chain lengths at least greater than C8, preferably at least C9 or at least C12.

[0166] Example 5 Further tergometer testing was performed to determine the cleaning power of various evaluated laundry formulations against lip cosmetic stains. Longer branched chain length polyamines were evaluated in comparison to Example 5. The detergent formulations shown in FIG. 5 were evaluated using the procedure described in Example 1 (Cover Girl #435 was washed at 120F for 10 minutes on cotton labé lipstick). The detergent formulations included caustic builders and were combined with either a control detergent or various branched polyamines according to embodiments of the present disclosure. The results are shown in FIG. 5, and show that the C18 chain length branched polyamine (Amine 2) provided suitable stain removal for laundry applications compared to the commercial control.
