Patent Description:
Various fabric substrates, textiles and laundry are often soiled from lip cosmetic soils that rub off a person's lips and onto the textiles and laundry. The lip cosmetic soil is typically very difficult to remove because of the waxy, oily and/or greasy consistency. Recently, lip cosmetic soils have become even more difficult to remove as a result of advances in the lip cosmetic industry such as new "long-wearing" lipsticks. In the past, such fabric substrates have been run through various pretreatment and/or washing processes depending on the particular method used in an effort to remove such difficult stains. Pretreatments or soaking have been employed to remove lip cosmetic soils or at last loosen the soils prior to a conventional laundry wash cycle. Often these pretreatments require submerging the substrate into a cleaning composition to sufficiently contact the soil. Additional processes include, for example, rewashing the substrate, manually scrubbing the substrate, and/or adding additional time to the laundry wash cycle to remove such soils. There remains a need for improved soil removal for lip cosmetics.

<CIT> refers to a hard surface cleaning composition comprising: a) from <NUM>% to <NUM>% by weight of the composition of a surfactant System; and b) from <NUM> % to <NUM>% by weight of the composition of a cleaning amine.

<CIT> refers to stable, solid triamine compositions. The pressed, cast, extruded or other solid compositions are suitable for antimicrobial, sanitizing and disinfectant applications. Ready-to-use solutions are obtained by dissolving the solid triamine compositions with water and the methods of use thereof are particularly suitable for cleaning, disinfecting, sanitizing, rinsing and/or lubricating.

<CIT> relates to methods of cleaning waxy, oily and/or greasy soils, including lip cosmetic soils such as lipsticks and lip gloss. In particular, the removal of lip cosmetic soils including lipstick and lip gloss stains in warewash, pretreatment and hard surface cleaning are disclosed through application of solid and/or liquid cleaning compositions comprising long chain polyamines.

<NPL> refers to a biocidal amine against gram positive and gram negative bacteria.

Accordingly, it is an objective to develop improved solid and/or liquid cleaning compositions for the effectively removal of waxy, oily and/or greasy soils, including lip cosmetic soils.

A further object is to provide improved laundry wash cycle performance for removing such lip cosmetic soils.

A further object is to provide cleaning compositions that do not require the use of a pretreatment step to soak the lip cosmetic soils on the fabric substrates.

A further object is to provide efficient methods of using such cleaning compositions.

Other objects, advantages and features of the present invention will become apparent from the following specification taken in conjunction with the accompanying drawings.

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 in common practice is ethylene oxide or a polyhydration product thereof, polyethylene glycol. Practically any hydrophobic compound having a hydroxyl, carboxyl, amino, or amido group with a reactive hydrogen atom can be condensed with ethylene oxide, or its polyhydration adducts, or its mixtures with alkoxylenes such as propylene oxide to form a nonionic surface-active agent. The length of the hydrophilic polyoxyalkylene moiety which is condensed with any particular hydrophobic compound can be readily adjusted to yield a water dispersible or water soluble compound having the desired degree of balance between hydrophilic and hydrophobic properties.

All of these ester moieties have one or more reactive hydrogen sites on their molecule which can undergo further acylation or ethylene oxide (alkoxide) addition to control the hydrophilicity of these substances. Care must be exercised when adding these fatty ester or acylated carbohydrates to compositions of the present invention containing amylase and/or lipase enzymes because of potential incompatibility.

Examples of nonionic low foaming surfactants include:
Compounds from (<NUM>) which are modified, essentially reversed, by adding ethylene oxide to ethylene glycol to provide a hydrophile of designated molecular weight; and, then adding propylene oxide to obtain hydrophobic blocks on the outside (ends) of the molecule. The hydrophobic portion of the molecule weighs from about <NUM>,<NUM> to about <NUM>,<NUM> with the central hydrophile including <NUM>% by weight to about <NUM>% by weight of the final molecule. These reverse Pluronics™ are manufactured by BASF Corporation under the trade name Pluronic™ R surfactants. Likewise, the Tetronic™ R surfactants are produced by BASF Corporation by the sequential addition of ethylene oxide and propylene oxide to ethylenediamine. The hydrophobic portion of the molecule weighs from about <NUM>,<NUM> to about <NUM>,<NUM> with the central hydrophile including <NUM>% by weight to <NUM>% by weight of the final molecule.

Compounds modified by "capping" or "end blocking" the terminal hydroxy group or groups (of multi-functional moieties) to reduce foaming by reaction with a small hydrophobic molecule such as propylene oxide, butylene oxide, benzyl chloride; and, short chain fatty acids, alcohols or alkyl halides containing from <NUM> to about <NUM> carbon atoms; and mixtures thereof. Also included are reactants such as thionyl chloride which convert terminal hydroxy groups to a chloride group. Such modifications to the terminal hydroxy group may lead to all-block, block-heteric, heteric-block or all-heteric nonionics.

A useful class of non-ionic surfactants include the class defined as alkoxylated amines or, most particularly, alcohol alkoxylated/aminated/alkoxylated surfactants. These non-ionic surfactants may be at least in part represented by the general formulae: R<NUM>-(PO)sN--(EO)tH, R<NUM>--(PO)sN--(EO)tH(EO)tH, and R<NUM>--N(EO)tH; in which R<NUM> is an alkyl, alkenyl or other aliphatic group, or an alkyl-aryl group of from <NUM> to <NUM>, preferably <NUM> to <NUM> carbon atoms, EO is oxyethylene, PO is oxypropylene, s is <NUM> to <NUM>, preferably <NUM>-<NUM>, t is <NUM>-<NUM>, preferably <NUM>-<NUM>, and u is <NUM>-<NUM>, preferably <NUM>-<NUM>.

These compounds are represented commercially by a line of products sold by Huntsman Chemicals as nonionic surfactants. A preferred chemical of this class includes Surfonic™ PEA <NUM> Amine Alkoxylate. Preferred nonionic surfactants for the compositions of the invention include alcohol alkoxylates, EO/PO block copolymers, alkylphenol alkoxylates, and the like.

The treatise<NPL> is an excellent reference on the wide variety of nonionic compounds generally employed in the practice of the present invention. A typical listing of nonionic classes, and species of these surfactants, is given in <CIT>. Further examples are given in "Surface Active Agents and detergents" (Vol. I and II by Schwartz, Perry and Berch).

The semi-polar type of nonionic surface active agents are another class of nonionic surfactant useful in compositions of the present invention. Generally, semi-polar nonionics are high foamers and foam stabilizers, which can limit their application in CIP systems. However, within compositional embodiments of this invention designed for high foam cleaning methodology, semi-polar nonionics would have immediate utility. The semi-polar nonionic surfactants include the amine oxides, phosphine oxides, sulfoxides and their alkoxylated derivatives.

Amine oxides are tertiary amine oxides corresponding to the general formula:
<CHM>
wherein the arrow is a conventional representation of a semi-polar bond; and, R<NUM>, R<NUM>, and R<NUM> may be aliphatic, aromatic, heterocyclic, alicyclic, or combinations thereof. Generally, for amine oxides of detergent interest, R<NUM> is an alkyl radical of from about <NUM> to about <NUM> carbon atoms; R<NUM> and R<NUM> are alkyl or hydroxyalkyl of <NUM>-<NUM> carbon atoms or a mixture thereof; R<NUM> and R<NUM> can be attached to each other, e.g. through an oxygen or nitrogen atom, to form a ring structure; R<NUM> is an alkaline or a hydroxyalkylene group containing <NUM> to <NUM> carbon atoms; and n ranges from <NUM> to about <NUM>.

Useful water soluble amine oxide surfactants are selected from the coconut or tallow alkyl di-(lower alkyl) amine oxides, specific examples of which are dodecyldimethylamine oxide, tridecyldimethylamine oxide, etradecyldimethylamine oxide, pentadecyldimethylamine oxide, hexadecyldimethylamine oxide, heptadecyldimethylamine oxide, octadecyldimethylaine oxide, dodecyldipropylamine oxide, tetradecyldipropylamine oxide, hexadecyldipropylamine oxide, tetradecyldibutylamine oxide, octadecyldibutylamine oxide, bis(<NUM>-hydroxyethyl)dodecylamine oxide, bis(<NUM>-hydroxyethyl)-<NUM>-dodecoxy-<NUM>-hydroxypropylamine oxide, dimethyl-(<NUM>-hydroxydodecyl)amine oxide, <NUM>,<NUM>,<NUM>-trioctadecyldimethylamine oxide and <NUM>-dodecoxy-<NUM>-hydroxypropyldi-(<NUM>-hydroxyethyl)amine oxide.

Useful semi-polar nonionic surfactants also include the water soluble phosphine oxides having the following structure:
<CHM>
wherein the arrow is a conventional representation of a semi-polar bond; and, R<NUM> is an alkyl, alkenyl or hydroxyalkyl moiety ranging from <NUM> to about <NUM> carbon atoms in chain length; and, R<NUM> and R<NUM> are each alkyl moieties separately selected from alkyl or hydroxyalkyl groups containing <NUM> to <NUM> carbon atoms.

<CHM>
wherein the arrow is a conventional representation of a semi-polar bond; and, R<NUM> is an alkyl or hydroxyalkyl moiety of about <NUM> to about <NUM> carbon atoms, from <NUM> to about <NUM> ether linkages and from <NUM> to about <NUM> hydroxyl substituents; and R<NUM> is an alkyl moiety consisting of alkyl and hydroxyalkyl groups having <NUM> to <NUM> carbon atoms.

Semi-polar nonionic surfactants for the compositions of the invention include dimethyl amine oxides, such as lauryl dimethyl amine oxide, myristyl dimethyl amine oxide, cetyl dimethyl amine oxide, combinations thereof, and the like. Useful water soluble amine oxide surfactants are selected from the octyl, decyl, dodecyl, isododecyl, coconut, or tallow alkyl di-(lower alkyl) amine oxides, specific examples of which are octyldimethylamine oxide, nonyldimethylamine oxide, decyldimethylamine oxide, undecyldimethylamine oxide, dodecyldimethylamine oxide, iso-dodecyldimethyl amine oxide, tridecyldimethylamine oxide, tetradecyldimethylamine oxide, pentadecyldimethylamine oxide, hexadecyldimethylamine oxide, heptadecyldimethylamine oxide, octadecyldimethylaine oxide, dodecyldipropylamine oxide, tetradecyldipropylamine oxide, hexadecyldipropylamine oxide, tetradecyldibutylamine oxide, octadecyldibutylamine oxide, bis(<NUM>-hydroxyethyl)dodecylamine oxide, bis(<NUM>-hydroxyethyl)-<NUM>-dodecoxy-<NUM>-hydroxypropylamine oxide, dimethyl-(<NUM>-hydroxydodecyl)amine oxide, <NUM>,<NUM>,<NUM>-trioctadecyldimethylamine oxide and <NUM>-dodecoxy-<NUM>-hydroxypropyldi-(<NUM>-hydroxyethyl)amine oxide.

Also useful in the present invention are surface active substances which are categorized as anionics because the charge on the hydrophobe is negative; or surfactants in which the hydrophobic section of the molecule carries no charge unless the pH is elevated to neutrality or above (e.g. carboxylic acids). Carboxylate, sulfonate, sulfate and phosphate are the polar (hydrophilic) solubilizing groups found in anionic surfactants. Of the cations (counter ions) 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 those skilled in the art understand, anionics are excellent detersive surfactants and are therefore favored additions to heavy duty detergent compositions.

Anionic sulfate surfactants suitable for use in the present compositions include alkyl ether sulfates, alkyl sulfates, the linear and branched primary and secondary alkyl sulfates, alkyl ethoxysulfates, fatty oleyl glycerol sulfates, alkyl phenol ethylene oxide ether sulfates, the C<NUM> -C<NUM> acyl-N-(C<NUM> -C<NUM> alkyl) and -N-(C<NUM> -C<NUM> hydroxyalkyl) glucamine sulfates, and sulfates of alkylpolysaccharides such as the sulfates of alkylpolyglucoside, and the like. Also included are the alkyl sulfates, alkyl poly(ethyleneoxy) ether sulfates and aromatic poly(ethyleneoxy) sulfates such as the sulfates or condensation products of ethylene oxide and nonyl phenol (usually having <NUM> to <NUM> oxyethylene groups per molecule).

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

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 which contain a carboxyl unit connected to a secondary carbon. The secondary carbon can be in a ring structure, e.g. as in p-octyl benzoic acid, or as in alkyl-substituted cyclohexyl carboxylates. The secondary carboxylate surfactants typically contain no ether linkages, no ester linkages and no hydroxyl groups. Further, they typically lack nitrogen atoms in the head-group (amphiphilic portion). Suitable secondary soap surfactants typically contain <NUM>-<NUM> total carbon atoms, although more carbons atoms (e.g., up to <NUM>) can be present. Suitable carboxylates also include acylamino acids (and salts), such as acylgluamates, acyl peptides, sarcosinates (e.g. N-acyl sarcosinates), taurates (e.g. N-acyl taurates and fatty acid amides of methyl tauride), and the like.

Suitable anionic surfactants include alkyl or alkylaryl ethoxy carboxylates of the following formula:.

R - O - (CH<NUM>CH<NUM>O)n(CH<NUM>)m - CO<NUM>X     (<NUM>).

in which R is a C<NUM> to C<NUM> alkyl group or
<CHM>
in which R<NUM> is a C<NUM>-C<NUM> alkyl group; n is an integer of <NUM>-<NUM>; m is an integer of <NUM>-<NUM>; and X is a counter ion, such as hydrogen, sodium, potassium, lithium, ammonium, or an amine salt such as monoethanolamine, diethanolamine or triethanolamine. In some embodiments, n is an integer of <NUM> to <NUM> and m is <NUM>. In some embodiments, R is a C<NUM>-C<NUM> alkyl group. In some embodiments, R is a C<NUM>-C<NUM> alkyl group, n is <NUM>, and m is <NUM>.

In other embodiments, R is
<CHM>
and R<NUM> is a C<NUM>-C<NUM> alkyl group. In still yet other embodiments, R<NUM> is a C<NUM> alkyl group, n is <NUM> and m is <NUM>.

Such alkyl and alkylaryl ethoxy carboxylates are commercially available. These ethoxy carboxylates are typically available as the acid forms, which can be readily converted to the anionic or salt form. Commercially available carboxylates include, Neodox <NUM>-<NUM>, a C<NUM>-<NUM> alkyl polyethoxy (<NUM>) carboxylic acid (Shell Chemical), and Emcol CNP-<NUM>, a C<NUM> alkylaryl polyethoxy (<NUM>) carboxylic acid (Witco Chemical). Carboxylates are also available from Clariant, e.g. the product Sandopan® DTC, a C<NUM> alkyl polyethoxy (<NUM>) carboxylic acid.

Surface active substances are classified as cationic if the charge on the hydrotrope portion of the molecule is positive. Surfactants in which the hydrotrope carries no charge unless the pH is lowered close to neutrality or lower, but which are then cationic (e.g. alkyl amines), are also included in this group. In theory, cationic surfactants may be synthesized from any combination of elements containing an "onium" structure RnX+Y-- and could include compounds other than nitrogen (ammonium) such as phosphorus (phosphonium) and sulfur (sulfonium). In practice, the cationic surfactant field is dominated by nitrogen containing compounds, probably because synthetic routes to nitrogenous cationics are simple and straightforward and give high yields of product, which can make them less expensive.

Cationic surfactants preferably refer to compounds containing at least one long carbon chain hydrophobic group and at least one positively charged nitrogen. The long carbon chain group may be attached directly to the nitrogen atom by simple substitution; or more preferably indirectly by a bridging functional group or groups in so-called interrupted alkylamines and amido amines. Such functional groups can make the molecule more hydrophilic and/or more water dispersible, more easily water solubilized by co-surfactant mixtures, and/or water soluble. For increased water solubility, additional primary, secondary or tertiary amino groups can be introduced or the amino nitrogen can be quaternized with low molecular weight alkyl groups. Further, the nitrogen can be a part of branched or straight chain moiety of varying degrees of unsaturation or of a saturated or unsaturated heterocyclic ring. In addition, cationic surfactants may contain complex linkages having more than one cationic nitrogen atom.

The surfactant compounds classified as amine oxides, amphoterics and zwitterions are themselves typically cationic in near neutral to acidic pH solutions and can overlap surfactant classifications. Polyoxyethylated cationic surfactants generally behave like nonionic surfactants in alkaline solution and like cationic surfactants in acidic solution.

The majority of large volume commercial cationic surfactants can be subdivided into four major classes and additional sub-groups known to those or skill in the art and described in "<NPL>). The first class includes alkylamines and their salts. The second class includes alkyl imidazolines. The third class includes ethoxylated amines. The fourth class includes quaternaries, such as alkylbenzyldimethylammonium salts, alkyl benzene salts, heterocyclic ammonium salts, tetra alkylammonium salts, and the like. Cationic surfactants are known to have a variety of properties that can be beneficial in the present compositions. These desirable properties can include detergency in compositions of or below neutral pH, antimicrobial efficacy, thickening or gelling in cooperation with other agents, and the like.

Cationic surfactants useful in the compositions of the present invention include those having the formula R<NUM>mR<NUM>xYLZ wherein each R<NUM> is an organic group containing a straight or branched alkyl or alkenyl group optionally substituted with up to three phenyl or hydroxy groups and optionally interrupted by up to four of the following structures:
<CHM>
or an isomer or mixture of these structures, and which contains from about <NUM> to <NUM> carbon atoms. The R<NUM> groups can additionally contain up to <NUM> ethoxy groups. m is a number from <NUM> to <NUM>. Preferably, no more than one R<NUM> group in a molecule has <NUM> or more carbon atoms when m is <NUM> or more than <NUM> carbon atoms when m is <NUM>. Each R<NUM> is an alkyl or hydroxyalkyl group containing from <NUM> to <NUM> carbon atoms or a benzyl group with no more than one R<NUM> in a molecule being benzyl, and x is a number from <NUM> to <NUM>, preferably from <NUM> to <NUM>. The remainder of any carbon atom positions on the Y group are filled by hydrogens. Y is can be a group including, but not limited to:
<CHM>
<CHM>
p = about <NUM> to <NUM>
<CHM>
p = about <NUM> to <NUM>
<CHM>
<CHM>
or a mixture thereof. Preferably, L is <NUM> or <NUM>, with the Y groups being separated by a moiety selected from R<NUM> and R<NUM> analogs (preferably alkylene or alkenylene) having from <NUM> to about <NUM> carbon atoms and two free carbon single bonds when L is <NUM>. Z is a water soluble anion, such as a halide, sulfate, methylsulfate, hydroxide, or nitrate anion, particularly preferred being chloride, bromide, iodide, sulfate or methyl sulfate anions, in a number to give electrical neutrality of the cationic component.

Amphoteric, or ampholytic, surfactants contain both a basic and an acidic hydrophilic group and an organic hydrophobic group. These ionic entities may be any of anionic or cationic groups described herein for other types of surfactants. A basic nitrogen and an acidic carboxylate group are the typical functional groups employed as the basic and acidic hydrophilic groups. In a few surfactants, sulfonate, sulfate, phosphonate or phosphate provide the negative charge.

Amphoteric surfactants can be broadly described as derivatives of aliphatic secondary and tertiary amines, in which the aliphatic radical may be straight chain or branched and wherein one of the aliphatic substituents contains from about <NUM> to <NUM> carbon atoms and one contains an anionic water solubilizing group, e.g., carboxy, sulfo, sulfato, phosphato, or phosphono. Amphoteric surfactants are subdivided into two major classes known to those of skill in the art and described in "<NPL>). The first class includes acyl/dialkyl ethylenediamine derivatives (e.g. <NUM>-alkyl hydroxyethyl imidazoline derivatives) and their salts. The second class includes N-alkylamino acids and their salts. Some amphoteric surfactants can be envisioned as fitting into both classes.

Amphoteric surfactants can be synthesized by methods known to those of skill in the art. For example, <NUM>-alkyl hydroxyethyl imidazoline is synthesized by condensation and ring closure of a long chain carboxylic acid (or a derivative) with dialkyl ethylenediamine. Commercial amphoteric surfactants are derivatized by subsequent hydrolysis and ring-opening of the imidazoline ring by alkylation -- for example with chloroacetic acid or ethyl acetate. During alkylation, one or two carboxy-alkyl groups react to form a tertiary amine and an ether linkage with differing alkylating agents yielding different tertiary amines.

Long chain imidazole derivatives having application in the present invention generally have the general formula:
<CHM>
Neutral pH Zwitterion AMPHOTERIC SULFONATE
<CHM>
wherein R is an acyclic hydrophobic group containing from about <NUM> to <NUM> carbon atoms and M is a cation to neutralize the charge of the anion, generally sodium. Commercially prominent imidazoline-derived amphoterics that can be employed in the present compositions include for example: Cocoamphopropionate, Cocoamphocarboxy-propionate, Cocoamphoglycinate, Cocoamphocarboxy-glycinate, Cocoamphopropyl-sulfonate, and Cocoamphocarboxy-propionic acid. Amphocarboxylic acids can be produced from fatty imidazolines in which the dicarboxylic acid functionality of the amphodicarboxylic acid is diacetic acid and/or dipropionic acid.

The carboxymethylated compounds (glycinates) described herein above frequently are called betaines. Betaines are a special class of amphoteric discussed herein below in the section entitled, Zwitterion Surfactants.

Long chain N-alkylamino acids are readily prepared by reaction RNH<NUM>, in which R=C<NUM>-C<NUM> straight or branched chain alkyl, fatty amines with halogenated carboxylic acids. Alkylation of the primary amino groups of an amino acid leads to secondary and tertiary amines. Alkyl substituents may have additional amino groups that provide more than one reactive nitrogen center. Most commercial N-alkylamine acids are alkyl derivatives of beta-alanine or beta-N(<NUM>-carboxyethyl) alanine. Examples of commercial N-alkylamino acid ampholytes having application in this invention include alkyl beta-amino dipropionates, RN(C<NUM>H<NUM>COOM)<NUM> and RNHC<NUM>H<NUM>COOM. In an embodiment, R can be an acyclic hydrophobic group containing from about <NUM> to about <NUM> carbon atoms, and M is a cation to neutralize the charge of the anion.

Suitable amphoteric surfactants include those derived from coconut products such as coconut oil or coconut fatty acid. Additional suitable coconut derived surfactants include as part of their structure an ethylenediamine moiety, an alkanolamide moiety, an amino acid moiety, e.g., glycine, or a combination thereof; and an aliphatic substituent of from about <NUM> to <NUM> (e.g., <NUM>) carbon atoms. Such a surfactant can also be considered an alkyl amphodicarboxylic acid. These amphoteric surfactants can include chemical structures represented as: C<NUM>-alkyl-C(O)-NH-CH<NUM>-CH<NUM>-N+(CH<NUM>-CH<NUM>-CO<NUM>Na)<NUM>-CH<NUM>-CH<NUM>-OH or C<NUM>-alkyl-C(O)-N(H)-CH<NUM>-CH<NUM>-N+(CH<NUM>-CO<NUM>Na)<NUM>-CH<NUM>-CH<NUM>-OH. Disodium cocoampho dipropionate is one suitable amphoteric surfactant and is commercially available under the tradename Miranol™ FBS from Rhodia Inc. , Cranbury, N. Another suitable coconut derived amphoteric surfactant with the chemical name disodium cocoampho diacetate is sold under the tradename Mirataine™ JCHA, also from Rhodia Inc. , Cranbury, N.

A typical listing of amphoteric classes, and species of these surfactants, is given in <CIT>. Further examples are given in "Surface Active Agents and Detergents" (Vol. I and II by Schwartz, Perry and Berch).

Zwitterionic surfactants can be thought of as a subset of the amphoteric surfactants and can include an anionic charge. 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, a zwitterionic surfactant includes a positive charged quaternary ammonium or, in some cases, a sulfonium or phosphonium ion; a negative charged carboxyl group; and an alkyl group. Zwitterionics generally contain cationic and anionic groups which ionize to a nearly equal degree in the isoelectric region of the molecule and which can develop strong" inner-salt" attraction between positive-negative charge centers. Examples of such zwitterionic synthetic surfactants include derivatives of aliphatic quaternary ammonium, phosphonium, and sulfonium compounds, in which the aliphatic radicals can be straight chain or branched, and wherein one of the aliphatic substituents contains from <NUM> to <NUM> carbon atoms and one contains an anionic water solubilizing group, e.g., carboxy, sulfonate, sulfate, phosphate, or phosphonate.

Betaine and sultaine surfactants are exemplary zwitterionic surfactants for use herein. A general formula for these compounds is:
<CHM>
wherein R<NUM> contains an alkyl, alkenyl, or hydroxyalkyl radical of from <NUM> to <NUM> carbon atoms having from <NUM> to <NUM> ethylene oxide moieties and from <NUM> to <NUM> glyceryl moiety; Y is selected from the group consisting of nitrogen, phosphorus, and sulfur atoms; R<NUM> is an alkyl or monohydroxy alkyl group containing <NUM> to <NUM> carbon atoms; x is <NUM> when Y is a sulfur atom and <NUM> when Y is a nitrogen or phosphorus atom, R<NUM> is an alkylene or hydroxy alkylene or hydroxy alkylene of from <NUM> to <NUM> carbon atoms and Z is a radical selected from the group consisting of carboxylate, sulfonate, sulfate, phosphonate, and phosphate groups.

Examples of zwitterionic surfactants having the structures listed above include: <NUM>-[N,N-di(<NUM>-hydroxyethyl)-N-octadecylammonio]-butane-<NUM>-carboxylate; <NUM>-[S-<NUM>-hydroxypropyl-S-hexadecylsulfonio]-<NUM>-hydroxypentane-<NUM>-sulfate; <NUM>-[P,P-diethyl-P-<NUM>,<NUM>,<NUM>-trioxatetracosanephosphonio]-<NUM>-hydroxypropane-<NUM>-phosphate; <NUM>-[N,N-dipropyl-N-<NUM>-dodecoxy-<NUM>-hydroxypropyl-ammonio]-propane-<NUM>-phosphonate; <NUM>-(N,N-dimethyl-N-hexadecylammonio)-propane-<NUM>-sulfonate; <NUM>-(N,N-dimethyl-N-hexadecylammonio)-<NUM>-hydroxy-propane-<NUM>-sulfonate; <NUM>-[N,N-di(<NUM>(<NUM>-hydroxyethyl)-N(<NUM>-hydroxydodecyl)ammonio]-butane-<NUM>-carboxylate; <NUM>-[S-ethyl-S-(<NUM>-dodecoxy-<NUM>-hydroxypropyl)sulfonio]-propane-<NUM>-phosphate; <NUM>-[P,P-dimethyl-P-dodecylphosphonio]-propane-<NUM>-phosphonate; and S[N,N-di(<NUM>-hydroxypropyl)-N-hexadecylammonio]-<NUM>-hydroxy-pentane-<NUM>-sulfate. The alkyl groups contained in said detergent surfactants can be straight or branched and saturated or unsaturated.

The zwitterionic surfactant suitable for use in the present compositions includes a betaine of the general structure:
<CHM>.

These surfactant betaines typically do not exhibit strong cationic or anionic characters at pH extremes nor do they show reduced water solubility in their isoelectric range. Unlike "external" quaternary ammonium salts, betaines are compatible with anionics. Examples of suitable betaines include coconut acylamidopropyldimethyl betaine; hexadecyl dimethyl betaine; C<NUM>-<NUM> acylamidopropylbetaine; C<NUM>-<NUM> acylamidohexyldiethyl betaine; <NUM>-C<NUM>-<NUM> acylmethylamidodiethylammonio-<NUM>-carboxybutane; C<NUM>-<NUM> acylamidodimethylbetaine; C<NUM>-<NUM> acylamidopentanediethylbetaine; and C<NUM>-<NUM> acylmethylamidodimethylbetaine.

Sultaines useful in the present invention include those compounds having the formula (R(R<NUM>)<NUM> N+ R<NUM>SO<NUM>-, in which R is a C<NUM> -C<NUM> hydrocarbyl group, each R<NUM> is typically independently C<NUM>-C<NUM> alkyl, e.g. methyl, and R<NUM> is a C<NUM>-C<NUM> hydrocarbyl group, e.g. a C<NUM>-C<NUM> alkylene or hydroxyalkylene group.

A typical listing of zwitterionic classes, and species of these surfactants, is given in <CIT>. Further examples are given in "Surface Active Agents and Detergents" (Vol. I and II by Schwartz, Perry and Berch).

The compositions and methods of the invention can optionally include a defoaming agent. Defoaming agents can be particularly suitable for embodiments including foaming surfactants, such as anionic surfactants. Generally, defoamers which can be used include silica and silicones; aliphatic acids or esters; alcohols; sulfates or sulfonates; amines or amides; halogenated compounds such as fluorochlorohydrocarbons; vegetable oils, waxes, mineral oils as well as their sulfonated or sulfated derivatives; fatty acids and/or their soaps such as alkali, alkaline earth metal soaps; and phosphates and phosphate esters such as alkyl and alkaline diphosphates, and tributyl phosphates among others; and mixtures thereof.

In some embodiments, the compositions can include antifoaming agents or defoamers which are of food grade quality given the application of the method of the invention. To this end, one of the more effective antifoaming agents includes silicones. Silicones such as dimethyl silicone, glycol polysiloxane, methylphenol polysiloxane, trialkyl or tetralkyl silanes, hydrophobic silica defoamers and mixtures thereof can all be used in defoaming applications. Commercial defoamers commonly available include silicones such as ARDEFOAM™ from Armour Industrial Chemical Company which is a silicone bound in an organic emulsion; FOAM KILL™ or KRESSEO™ available from Krusable Chemical Company which are silicone and non-silicone type defoamers as well as silicone esters; and ANTI-FOAM A™ and DC-<NUM> from Dow Corning Corporation which are both food grade type silicones among others.

In some embodiments, the compositions may further include enzymes. Preferrably in the cleaning compositions that do not include an alkalinity source enzymes and water make up a large amount of the cleaning composition.

Since enzymes are proteins, it is important that the other components of the composition not serve to denature the enzyme thus rendering it ineffective for its intended purpose. For preferred cleaning compositions incorporating active enzymes or enzymes otherwise stabilized, the pH of the composition is important. That is, the pH of a composition including an enzymatic should be such that the enzymatic component remains stable and is not denatured. Such a pH may be at or near about neutral pH or between about <NUM> and <NUM>. For certain enzymes such a pH may be at or between about <NUM> and about <NUM>. As one skilled in the art will ascertain, there is a difference between a stable enzyme and an active enzyme. For example, an enzyme can be formulated in a composition at pH <NUM> and could be considered stable but not active; thereafter once the enzyme is used in an alkaline composition/application that modifies the pH of the composition (e.g. from <NUM> to <NUM>), the enzyme will become active when the pH changes to its "ideal" pH that is higher (e.g. pH <NUM>).

Amylases are examples of enzymes useful in the cleaning compositions. Examples of amylases which can be used are the alpha-amylases from Bacillus licheniformis, from B. amyloliquiefaciens or B. stearothermophilus and developments thereof which have been improved for use in washing and cleaning compositions. Novozymes and Genencor sell commercially-avialble alpha-amylases derived from one or all of the above-mentioned bacterial species. Novozymes further offers alpha-amylase from Aspergillus niger and A.

Proteases are examples of enzymes useful in the cleaning compositions. Protease can be derived from a microorganism, such as a yeast, a mold, or a bacterium. An example of proteolytic enzyme which can be employed in the cleaning composition include Savinase. Protease derived from Bacillus lentus, Bacillus licheniformis, Bacillus amyloliquefaciens, Bacillus alcalophilus, are commercially-aviable from Genencor International, Solvay Enzymes, Novozymes, and the like.

Preferred enzymes provide good protein removal and cleaning performance, will not leave behind a residue, and will be easy to formulate with and form stable products. For example, Savinase, commercially available from Novozymes, is a serine-type endo-protease and has activity in a pH range of <NUM> to <NUM> and a temperature range from 20C to 60C. As a further example, Alcalase, commercially available from Novozymes, is derived from Bacillus licheniformis and has activity in a pH range of <NUM> to <NUM> and a temperature range from 45C to 65C. Esperase is commercially available from Novozymes, is derived from Bacillus sp. and has an alkaline pH activity range and a temperature range from 50C to 85C.

Mixtures of different enzymes may be incorporated into the cleaning compositions. While various specific enzymes have been described above, it is to be understood that any enzyme, such as protease which can confer the desired proteolytic activity to the composition may be used. Compositions of the invention include from about <NUM> wt-% to about <NUM> wt-% enzyme, from about <NUM> wt-% to about <NUM> wt-% enzyme, from about <NUM> wt-% to about <NUM> wt-% enzyme, from about <NUM> wt-% to about <NUM> wt-% enzyme, from about <NUM> wt-% - to about <NUM> wt-% enzyme. In addition, without being limited according to the invention, all ranges recited are inclusive of the numbers defining the range and include each integer within the defined range.

In some embodiments, the compositions may further include a chelant. Chelation herein means the binding or complexation of a bi- or multidentate ligand. These ligands, which are often organic compounds, are called chelants, chelators, chelating agents, and/or sequestering agent. Chelating agents form multiple bonds with a single metal ion. Chelants, are chemicals that form soluble, complex molecules with certain metal ions, inactivating the 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 reserved for complexes in which the metal ion is bound to two or more atoms of the chelant.

Suitable aminocarboxylic acid type chelants include the acids, or alkali metal salts thereof. Some examples of aminocarboxylic acid materials include amino acetates and salts thereof. Some examples include the following: 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 the like; and mixtures thereof. Particularly useful aminocarboxylic acid materials containing little or no NTA and no phosphorus 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), <NUM>-hydroxyethyliminodiacetic acid (HEIDA), iminodisuccinic acid (IDS), <NUM>-hydroxy-<NUM>,<NUM>'-iminodisuccinic acid (HIDS) and other similar acids having an amino group with a carboxylic acid substituent.

Suitable chelating agents include amino carboxylates, amino phosphonates, polyfunctionally-substituted aromatic chelating agents and mixtures thereof. Exemplary chelants include amino acids based chelants and preferably citrate, tartrate, and glutamic-N,N-diacetic acid and derivatives and/or phosphonate based chelants.

Other chelants include homopolymers and copolymers of polycarboxylic acids and their partially or completely neutralized salts, monomeric polycarboxylic acids and hydroxycarboxylic acids and their salts. Preferred salts of the abovementioned compounds are the ammonium and/or alkali metal salts, i.e. the lithium, sodium, and potassium salts, and particularly preferred salts are the sodium salts, such as sodium sulfate.

Other chelants include a polycarboxylic acid polymers. Representative polycarboxylic acid polymers suitable for the rinse composition include amino carboxylic acids, water soluble acrylic polymers, polymaleic homopolymers, maleic polymers, among others to condition the rinse solutions under end use conditions.

Water soluble salts orpartial salts of these polymers such as their respective alkali metal (for example, sodium or potassium) or ammonium salts can also be used.

In addition, phosphonic acid salts or phosphonate sequestrants may also be employed. In some embodiments, the phosphonic acid salts and/or phosphonate sequestrants may be employed alone, without the polycarboxylic acid polymers. Such useful phosphonic acids include, mono, di, tri and tetraphos-phonic acids which can also contain groups capable of forming anions under alkaline conditions such as carboxy, hydroxy, thio and the like.

In an embodiment the compositions optionally include water conditioning polymer(s). In some aspects a water conditioning polymer is a secondary builder or scale inhibitor for the compositions. According to an embodiment, the water conditioning polymer may be a non-phosphorus polymer. In an aspect, the water conditioning polymer is a nonionic surfactant.

The methods of cleaning are particularly well suited for removing lip cosmetic soils. While not wanting to be held to a scientific theory, it is believed that the hydrophobic portion of the lip cosmetic soils make the soil particularly difficult to remove from soiled substrates. The hydrophobic portion of the lip cosmetic may be an oil, a viscous solid, or a wax, depending on the desired consistency of the final product. For example, a lip gloss that is rolled onto the lips will tend to be more liquid in consistency than a lip gloss that is applied using a fingertip. Naturally, one would expect the roll on lip gloss to have a higher oil content than a fingertip lip gloss, which would have more solids or waxes. The hydrophobic component of lip cosmetics may be natural or synthetic. The following is a list of non-limiting examples of hydrophobic materials that are 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, montan 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-<NUM> beeswax, PEG-<NUM> beeswax, PEG-<NUM> beeswax, PEG-<NUM> beeswax, PEG-<NUM> carnauba, petrolatum, petroleum jelly, potassium oxidized microcrystalline wax, rice (Oryza sativa) wax, sesame (Sesamum indicum) oil, shea butter (Butyrospermum parkii), shellac wax, spent grain wax, stearic acid, sulfurized jojoba oil, synthetic beeswax, synthetic candelilla wax, synthetic carnauba, synthetic japan wax, synthetic jojoba oil, synthetic wax, and vegetable oil. Additional materials found in lip cosmetics include, for example, silicones, such as dimethicone, along with other pigments, dyes, colorants and fragrances.

It is understood that the compositions disclosed herein are capable of removing lip cosmetic soils having the hydrophobic and other materials described above as well as those not included in the list above.

The methods are particularly well suited for removing lip cosmetic soils that accumulate on any type of fabric substrates, such as textiles, and other hard surfaces. The methods of cleaning include contacting a fabric substrate or other hard surface in need of removing lip costmetic soils, including for example lipstick, lip stain, lip gloss, lip balm, and/or chapstick. In an aspect, the fabric substrate or hard surface is soiled with a waxy, oily and/or greasy soil. Any means of contacting can be used to place the fabric substrate or hard surface in contact with the alkaline cleaning compositions, including for example, soaking, spraying, dripping, wiping, or the like. Included within the scope of contacting described herin, the fabric substrate and/or hard surface can also be soaked, including a pretreatment or a wash cycle, with the alkaline compositions. As a result of the contacting step the surface is washed and the soils removed.

In an aspect, the surface is a fabric substrate, such as laundry. Exemplary laundry includes, for example, items or articles that are cleaned in a laundry washing machine. In general, laundry refers to any item or article made from or including textile materials, woven fabrics, non-woven fabrics, and knitted fabrics. The textile materials can 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 can be treated or untreated. Exemplary treated fibers include those treated for flame retardancy. It should be understood that the term "linen" is often used to describe certain types of laundry items including bed sheets, pillow cases, towels, and the like. The invention additionally provides a composition and method for treating non-laundry articles and surfaces including hard surfaces. Textile and laundry washing described herein can be washed manually. In an alternative aspect, the substrate is washed in a laundry machine.

In the washing applications, soaking (or pretreatment) applications and/or other hard surface treatment applications, the branched polyamines can be added to the cleaning composition in a use solution. Alternatively, a fully formulated cleaning composition can be provided. Laundry applications of use can include applying a pretreatment concentrate as a spray onto the substrate in need of treatment. The contacting time may varying from a few seconds to a few minutes. In other embodiments, a lower concentration of the cleaning compositions may be employed for a presoak application. In such embodiments the contact time can vary from a few minutes to a few hours.

A first step of diluting and/or creating an aqueous use solution (such as from a solid) can also be included in the methods. An exemplary dilution step includes contacting the 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 an embodiment, a concentrate composition can be diluted to a use solution before to application to an object. For reasons of economics, the concentrate can be marketed and an end user can dilute the concentrate with water or an aqueous diluent to a use solution. The level of active components in the concentrate composition is dependent on the intended dilution factor and the desired activity of the active components of the concentrate. Generally, a dilution of about <NUM> (<NUM> fluid ounce) to about <NUM> (<NUM> gallons) of water to about <NUM> (<NUM> fluid ounces) to about <NUM><NUM> (<NUM> gallon) of water is used for aqueous compositions. In some embodiments, when used in a laundry application, the concentrated compositions can be diluted at a dilution ratio of about <NUM>/L to about <NUM>/L concentrate to diluent, about <NUM>/L to about <NUM>/L concentrate to diluent, about <NUM>/L to about <NUM>/L concentrate to diluent, or about <NUM>/L to about <NUM>/L concentrate to diluent. In other embodiments, a use composition can include about <NUM> to about <NUM> wt-% of a concentrate composition and about <NUM> to about <NUM> wt-% diluent; or about <NUM> to about <NUM> wt-% of a concentrate composition and about <NUM> to about <NUM> wt-% diluent.

The alkaline cleaning compositions can be provided at an actives level in a ready to use and/or concentrate composition providing a desired amount of actives of the components of the compositions. In an aspect, the branched polyamine and/or additional surfactants are provided at a concentration from about <NUM> ppm to about <NUM>,<NUM> ppm in a use solution, from about <NUM> ppm to about <NUM> ppm in a use solution, from about <NUM> ppm to about <NUM> ppm in a use solution, or from about <NUM> ppm to about <NUM> ppm in a use solution.

In an aspect, the alkaline cleaning compositions contacts the textile substrates and/or other hard surface in need of cleaning at a use solution will have a pH of between about <NUM> and about <NUM>.

In an aspect, the alkaline cleaning compositions contacts the textile substrates and/or other hard surface for a sufficient amount of time to remove the soils, including from a few seconds to a few hours, including all ranges therebetween. In some aspects, the cleaning compositions can be employed in either a washing or in a pre-soak situation, such that the the articles are contacted with the composition of the invention at use temperature of at least about <NUM> (<NUM>°F) to about <NUM> (<NUM>°F), at least about <NUM> (<NUM>°F) to about <NUM> (<NUM>°F) or at least about <NUM> (<NUM>°F) to about <NUM> (<NUM>°F) for a period of time effective to clean the articles. This time is preferably a minimum of <NUM> hour, or <NUM> hours and a maximum of <NUM> hours.

The alkaline cleaning compositions can be used alone to treat the articles, e.g., textiles, or can be used in conjunction with conventional detergents suitable for the articles to be treated. The compositions can be used with conventional detergents in a variety of ways, for example, the compositions can be formulated with a conventional detergent. In other embodiments, the compositions can be used to treat the article as a separate additive from a conventional detergent. When used as a separate additive, the compositions can contact the article to be treated at any time. For example, the compositions can contact the article before, after, or substantially simultaneously as the articles are contacted with the selected detergent.

Embodiments of the present invention are further defined in the following non-limiting Examples. It should be understood that these Examples, while indicating certain embodiments of the invention, are given by way of illustration only.

The materials used in the following examples are provided herein:.

A tergotometer was used to measure detergency of various evaluated laundry formulations against lip cosmetic soils. The detergent formulations shown in <FIG> were evalulated using caustic based detergent compositions including a surfactant - utilizing a branched polyamine (Amine <NUM>) in comparison to conventional alkoxylate surfactants at a <NUM> ppm surfactant level.

APPARATUS: Tergotometer with <NUM> pots and water bath.

The percent lipstick removed is shown in <FIG>, which is a graphical depiction of percent lipstick removal with evalulated formulations. The greater the values denote more lipstick removed. Beneficially the evalulated formulation containing the branched polyamine surfactant (Amine <NUM>) provided <NUM>% soil removal, performing at least as well as the <NUM> ppm Tergitol NP-<NUM> (NPE) and outperformingthe alkoxylate surfactants and caustic formulations (negative control of Builder C alone).

Additional tergotometer testing was used to measure detergency of various evaluated laundry formulations against lip cosmetic soils. The caustic based detergent formulations shown in <FIG> were evaluated using the procedures described in Example <NUM>. A linear polyamine (Amine <NUM>), branched polyamine (Amine <NUM>) and various conventional surfactants were compared. The results are shown in <FIG> where the branched polyamine outperformed the linear polyamine and other evaluated amine-containing surfactants in lipstick soil removal.
