PATENT APPLICATION Docket No. P14677WO00-E12102WOU1 TITLE: MULTI-PART CLEANING COMPOSITIONS AND METHODS FOR TENACIOUS SOIL REMOVAL FROM MULTIPLE SUBSTRATES CROSS-REFERENCE TO RELATED APPLICATION

[0001] This application claims priority under 35 U.S.C. § 119 to Provisional Application U.S. Serial No. 63 / 656,173, filed on June 5, 2024, which is herein incorporated by reference in its entirety including without limitation, the specification, claims, and abstract, as well as any figures, tables, or examples thereof. TECHNICAL FIELD

[0002] The disclosure relates generally to compositions and methods for removing tenacious soils from various substrates. In particular the compositions and methods for soil removal employ a multi-part composition that provides a self-accelerating composition once a first part containing an alkaline accelerant and a second part containing a co-accelerant are in contact, providing an effective and safe to handle (not requiring personal protective equipment) composition for cleaning in a safe and sustainable manner. BACKGROUND

[0003] Tenacious soils can require multiple cleaning steps to remove the soils from substrates. Tenacious soils such as chewing gum, produce labels, cosmetics, polymerized cooking oil / fats, burnt on soils, carbohydrates and other tenacious soils may be removed using a combination of mechanical and chemical techniques. Tenacious soils are often found in the forms of baked on / polymerized cooking oils, fryer cleaners, oven cleaners, pizza pans, caramelized, confectionery, dairy, chewing gum, produce labels, banana sap cleaning, and nail polish / glitter based soils. Tenacious soils are also found on surrounding surfaces in foodservice locations, such as those often encountered on surfaces (e.g., floors, hoods, appliances (both interior and exterior surfaces), counter tops, shelves, walls, ceilings, and the like).

[0004] Many consumers do not wish to transport and / or handle highly alkaline and corrosive compositions as this presents a variety of safety concerns and hazards. This is a result of various requirements for personnel to use personal protective equipment (PPE) to reduce exposure to the hazardous or corrosive materials. PPE may include, for example, goggles, eye wash stations, masks, gloves, and other protective equipment. Therefore, it is desirable toPATENT APPLICATION Docket No. P14677WO00-E12102WOU1 provide a non-corrosive, lower pH cleaning composition that can disrupt the structure of tenacious, polymerized soils to adequately remove the soils and thereby clean surfaces without requiring use of PPE. Therefore, there exists a need for improved compositions, systems and methods to make such soils easier to remove.

[0005] Thus, there exists a need in the art for a multi-part cleaning compositions, kits containing the cleaning compositions, and methods for use thereof capable of removing extremely tenacious soils from multiple substrates with reduced cleaning time, improved worker safety and the addition of values to potential customers.

[0006] It is therefore an object of this disclosure to provide multi-part cleaning compositions, kits containing the cleaning compositions, and methods for use thereof to remove tenacious and challenging soils from various substrate surfaces.

[0007] It is a further object of the disclosure to provide multi-part cleaning compositions, kits containing the cleaning compositions, and methods for use thereof that reduce cleaning time.

[0070] In some embodiments, the solvent is included in the first part of the composition at an amount of at least about 1 wt-% to about 70 wt-%, about 10 wt-% to about 60 wt-%, about 20 wt-% to about 60 wt-%, or about 25 wt-% to about 50 wt-%. In addition, without being limited according to the disclosure, all ranges recited are inclusive of the numbers defining the range and include each integer within the defined range. Surfactants

[0071] The first part of the multi-part cleaning composition includes at least one emulsifying surfactant. In preferred embodiments the surfactant comprises an emulsifying nonionic surfactant, an emulsifying anionic surfactant, and / or an emulsifying cationic surfactant. For a discussion of surfactants, see Kirk-Othmer, Encyclopedia of Chemical Technology, Third Edition, volume 8, pages 900-912.

[0072] Emulsifying surfactants or mixtures of surfactants can have foaming or defoaming characteristics in the composition as required by a desired cleaning method. For example, in certain applications long lasting foam may be required which can extend the cleaning time on a surface for the compositions. In certain applications it may be desirable to minimize foaming and a surfactant or surfactant system that provides reduced foaming can be used. In addition, it may be desirable to select a surfactant or surfactant system that exhibits foam that breaks down relatively quickly so that the composition can be recovered and reused with anPATENT APPLICATION Docket No. P14677WO00-E12102WOU1 acceptable amount of down time. Without being limited to a particular mechanism of action, in some embodiments low foaming surfactants are preferred to minimize the amount of soils that remain or are trapped in foam and therefore less effectively removed from the surfaces to be cleaned.

[0073] The emulsifying surfactant(s) can include an emulsifying nonionic surfactant.

[0074] 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. Useful nonionic surfactants include:

[0075] Block polyoxypropylene-polyoxyethylene polymeric compounds based upon propylene glycol, ethylene glycol, glycerol, trimethylolpropane, and ethylenediamine as the initiator reactive hydrogen compound. Examples of polymeric compounds made from a sequential propoxylation and ethoxylation of initiator 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 the two hydroxyl groups of propylene glycol. This hydrophobic portion of the molecule weighs from about 1,000 to about 4,000. Ethylene oxide is then added to sandwich this hydrophobe between hydrophilic groups, controlled by length to constitute from about 10% by weight to about 80% by weight of the final molecule. Another class of compounds are tetra-flinctional block copolymers derived from the sequential addition of propylene oxide and ethylene oxide to ethylenediamine. The molecular weight of the propylene oxide hydrotype ranges from about 500 to about 7,000; and, the hydrophile, ethylene oxide, is added to constitute from about 10% by weight to about 80% by weight of the molecule.

[0076] Condensation products of one mole of alkyl phenol wherein the alkyl chain, of straight chain or branched chain configuration, or of single or dual alkyl constituent, containsPATENT APPLICATION Docket No. P14677WO00-E12102WOU1 from about 8 to about 18 carbon atoms with from about 3 to about 50 moles of ethylene oxide. The alkyl group can, for example, be represented by diisobutylene, di-amyl, polymerized propylene, iso-octyl, nonyl, and di-nonyl. These surfactants can be polyethylene, polypropylene, and polybutylene oxide condensates of alkyl phenols. Examples of commercial compounds of this chemistry are available on the market under the trade names Igepal®manufactured by Rhone-Poulenc and Triton®manufactured by Union Carbide.

[0077] Condensation products 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 moiety can consist of mixtures of alcohols in the above delineated carbon range or it can consist of an alcohol having a specific number of carbon atoms within this range. Examples of like commercial surfactant are available under the trade names Lutensol™, Dehydol™ manufactured by BASF, NeodolTMmanufactured by Shell Chemical Co. and AlfonicTMmanufactured by Vista Chemical Co.

[0078] Condensation products of one mole of 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 moiety can consist of mixtures of acids in the above defined carbon atoms range or it can consist of an acid having a specific number of carbon atoms within the range. Examples of commercial compounds of this chemistry are available on the market under the trade names Disponil or Agnique manufactured by BASF and LipopegTMmanufactured by Lipo Chemicals, Inc.

[0079] In addition to ethoxylated carboxylic acids, commonly called polyethylene glycol esters, other alkanoic acid esters formed by reaction with glycerides, glycerin, and polyhydric (saccharide or sorbitan / sorbitol) alcohols have application in this invention for specialized embodiments, particularly indirect food additive applications. 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 esters or acylated carbohydrates to compositions of the present invention containing amylase and / or lipase enzymes because of potential incompatibility.

[0080] Examples of nonionic low foaming surfactants include:

[0081] Compounds from (1) 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.PATENT APPLICATION Docket No. P14677WO00-E12102WOU1 The hydrophobic portion of the molecule weighs from about 1,000 to about 3,100 with the central hydrophile including 10% by weight to about 80% by weight of the final molecule. These reverse PluronicsTMare manufactured by BASF Corporation under the trade name PluronicTMR surfactants. Likewise, the TetronicTMR 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 2,100 to about 6,700 with the central hydrophile including 10% by weight to 80% by weight of the final molecule.

[0082] Compounds from groups (1), (2), (3) and (4) which are 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 1 to about 5 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.

Compounds falling within the scope of the definition for Y include, for example, propylene glycol, glycerine, pentaerythritol, trimethylolpropane, ethylenediamine and the like. The oxypropylene chains optionally, but advantageously, contain small amounts of ethylene oxide and the oxyethylene chains also optionally, but advantageously, contain small amounts of propylene oxide.

[0089] Additional conjugated polyoxyalkylene surface-active agents which are advantageously used in the compositions of this invention correspond to the formula: P[(C3H6O)n(C2H4O)mH]xwherein P is the residue of an organic compound having from about 8 to 18 carbon atoms and containing x reactive hydrogen atoms in which x has a value of 1 or 2, n has a value such that the molecular weight of the polyoxyethylene portion is at least about 44 and m has a value such that the oxypropylene content of the molecule is from about 10% to about 90% by weight. In either case the oxypropylene chains may contain optionally, but advantageously, small amounts of ethylene oxide and the oxyethylene chains may contain also optionally, but advantageously, small amounts of propylene oxide.

The alkyl chain of the aliphatic alcohol can either be straight or branched, primary or secondary, and generally contains from 6 to 22 carbon atoms.

[0092] The ethoxylated C6-C18 fatty alcohols and C6-C18 mixed ethoxylated and propoxylated fatty alcohols are suitable surfactants for use in the present compositions, particularly those that are water soluble. Suitable ethoxylated fatty alcohols include the C6-C18 ethoxylated fatty alcohols with a degree of ethoxylation of from 3 to 50. In an embodiment a preferred ethoxylated and propoxylated fatty alcohol is commercially available as Plurafac SL 62 which is a C6- C10Alcohols, ethoxylated and / or propoxylated.

[0093] Suitable nonionic alkylpolysaccharide surfactants, particularly for use in the present compositions include those disclosed in U.S. Pat. No.4,565,647, Llenado, issued Jan.21, 1986. These surfactants include a hydrophobic group containing from about 6 to about 30 carbon atoms and a polysaccharide, e.g., a polyglycoside, hydrophilic group containing from about 1.3 to about 10 saccharide units. Any reducing 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. positions thus giving a glucose or galactose as opposed to a glucoside or galactoside.) The intersaccharide bonds can be, e.g., between the one position of the additional saccharide units and the 2-, 3-, 4-, and / or 6-positions on the preceding saccharide units.

[0094] Fatty acid amide surfactants suitable for use the present compositions include those having the formula: R6CON(R7)2 in which R6 is an alkyl group containing from 7 to 21 carbon atoms and each R7is independently hydrogen, C1- C4alkyl, C1- C4hydroxyalkyl, or -- ( C2H4O)XH, where x is in the range of from 1 to 3.

[0095] 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: R20--(PO)SN--(EO)tH, R20--(PO)SN--(EO) tH(EO)tH, and R20--N(EO) tH; in which R20is an alkyl, alkenyl or otherPATENT APPLICATION Docket No. P14677WO00-E12102WOU1 aliphatic group, or an alkyl-aryl group of from 8 to 20, preferably 12 to 14 carbon atoms, EO is oxyethylene, PO is oxypropylene, s is 1 to 20, preferably 2-5, t is 1-10, preferably 2-5, and u is 1-10, preferably 2-5.

These compounds are represented commercially by a line of products sold by Huntsman Chemicals as nonionic surfactants. A preferred chemical of this class includes SurfonicTMPEA 25 Amine Alkoxylate. Preferred nonionic surfactants for the compositions of the invention include alcohol alkoxylates, EO / PO block copolymers, alkylphenol alkoxylates, and the like.

[0096] The treatise Nonionic Surfactants, edited by Schick, M. J., Vol.1 of the Surfactant Science Series, Marcel Dekker, Inc., New York, 1983 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 U.S. Pat. No. 3,929,678 issued to Laughlin and Heuring on Dec.30, 1975. Further examples are given in "Surface Active Agents and detergents" (Vol. I and II by Schwartz, Perry and Berch).

[0097] Semi-Polar Nonionic Surfactants

[0098] 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.

[0099] Amine oxides are tertiary amine oxides corresponding to the general formula:wherein the arrow is a conventional representation of a semi-polar bond; and, R1, R2, and R3may be aliphatic, aromatic, heterocyclic, alicyclic, or combinations thereof. Generally, for amine oxides of detergent interest, R1is an alkyl radical of from about 8 to about 24 carbon atoms; R2and R3are alkyl or hydroxyalkyl of 1-3 carbon atoms or a mixture thereof; R2andPATENT APPLICATION Docket No. P14677WO00-E12102WOU1 R3can be attached to each other, e.g. through an oxygen or nitrogen atom, to form a ring structure; R4is an alkaline or a hydroxyalkylene group containing 2 to 3 carbon atoms; and n ranges from 0 to about 20.

[0101] Useful semi-polar nonionic surfactants also include the water soluble phosphine oxides having the following structure:arrow is a conventional representation of a semi-polar bond; and, R1is an alkyl, alkenyl or hydroxyalkyl moiety ranging from 10 to about 24 carbon atoms in chain length; and, R2and R3are each alkyl moieties separately selected from alkyl or hydroxyalkyl groups containing 1 to 3 carbon atoms.

[0102] Examples of useful phosphine oxides include dimethyldecylphosphine oxide, dimethyltetradecylphosphine oxide, methylethyltetradecylphosphone oxide, dimethylhexadecylphosphine oxide, diethyl-2-hydroxyoctyldecylphosphine oxide, bis(2- hydroxyethyl)dodecylphosphine oxide, and bis(hydroxymethyl)tetradecylphosphine oxide.PATENT APPLICATION Docket No. P14677WO00-E12102WOU1

[0103] Semi-polar nonionic surfactants useful herein also include the water soluble sulfoxide compounds which have the structure:arrow is a conventional representation of a semi-polar bond; and, R1is an alkyl or hydroxyalkyl moiety of about 8 to about 28 carbon atoms, from 0 to about 5 ether linkages and from 0 to about 2 hydroxyl substituents; and R2is an alkyl moiety consisting of alkyl and hydroxyalkyl groups having 1 to 3 carbon atoms.

[0104] Useful examples of these sulfoxides include dodecyl methyl sulfoxide; 3-hydroxy tridecyl methyl sulfoxide; 3-methoxy tridecyl methyl sulfoxide; and 3-hydroxy-4- dodecoxybutyl methyl sulfoxide.

[0105] 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(2- hydroxyethyl)dodecylamine oxide, bis(2-hydroxyethyl)-3-dodecoxy-1-hydroxypropylamine oxide, dimethyl-(2-hydroxydodecyl)amine oxide, 3,6,9-trioctadecyldimethylamine oxide and 3-dodecoxy-2-hydroxypropyldi-(2-hydroxyethyl)amine oxide.

[0106] Suitable nonionic surfactants suitable for use with the compositions of the present invention include alkoxylated surfactants. Suitable alkoxylated surfactants include EO / PO copolymers, capped EO / PO copolymers, alcohol alkoxylates, capped alcohol alkoxylates, mixtures thereof, or the like. Suitable alkoxylated surfactants for use as solvents includePATENT APPLICATION Docket No. P14677WO00-E12102WOU1 EO / PO block copolymers, such as the Pluronic and reverse Pluronic surfactants; alcohol alkoxylates, such as Dehypon LS-54 (R-(EO)5(PO)4) and Dehypon LS-36 (R-(EO)3(PO)6); and capped alcohol alkoxylates, such as Plurafac LF221 and Tegoten EC11; mixtures thereof, or the like.

[0107] The emulsifying surfactant(s) can include an emulsifying cationic surfactant.

[0108] 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.

[0109] 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 C5-C17acyl-N-(C1-C4alkyl) and -N-(C1-C2hydroxyalkyl) 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 1 to 6 oxyethylene groups per molecule).

[0110] 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.

[0111] 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 ringPATENT APPLICATION Docket No. P14677WO00-E12102WOU1 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 11-13 total carbon atoms, although more carbons atoms (e.g., up to 16) 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.

[0112] Suitable anionic surfactants include alkyl or alkylaryl ethoxy carboxylates of the following formula: R - O - (CH2CH2O)n(CH2)m - CO2X (3) R in which R is a C8to C22alkyl group or , in which R1is a C4-C16alkyl group;n is an integer of 1-20; m is an integer of 1-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 4 to 10 and m is 1. In some embodiments, R is a C8-C16alkyl group. In some embodiments, R is a C12-C14alkyl group, n is 4, and m is 1. R

[0113] In other embodiments, R and R1is a C6-C12alkyl group. In still yet other embodiments, R1is a C9and m is 1.

[0114] 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 23-4, a C12-13 alkyl polyethoxy (4) carboxylic acid (Shell Chemical), and Emcol CNP-110, a C9 alkylaryl polyethoxy (10) carboxylic acid (Witco Chemical). Carboxylates are also available from Clariant, e.g. the product Sandopan®DTC, a C13 alkyl polyethoxy (7) carboxylic acid.

[0115] The emulsifying surfactant(s) can include an emulsifying cationic surfactant.

[0116] 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 couldPATENT APPLICATION Docket No. P14677WO00-E12102WOU1 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.

[0117] Cationic surfactants preferably include, more 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.

[0118] 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.

[0119] The simplest cationic amines, amine salts and quaternary ammonium compounds can be schematically drawn thus:in be either alkyl chains or aryl groups or hydrogen and X represents an anion. The amine salts and quaternary ammonium compounds are preferred for practical use in this invention due to their high degree of water solubility.

[0120] 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 describedPATENT APPLICATION Docket No. P14677WO00-E12102WOU1 in "Surfactant Encyclopedia", Cosmetics & Toiletries, Vol.104 (2) 86-96 (1989). 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.

The R1groups can additionally contain up to 12 ethoxy groups. m is a number from 1 to 3. Preferably, no more than one R1group in a molecule has 16 or more carbon atoms when m is 2 or more than 12 carbon atoms when m is 3. Each R2is an alkyl or hydroxyalkyl group containing from 1 to 4 carbon atoms or a benzyl group with no more than one R2in a molecule being 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 filled by hydrogens.PATENT APPLICATION Docket No. P14677WO00-E12102WOU1 Y is can be a group including, but not limited to:Y groups being separated by a moiety selected from R1and R2analogs (preferably alkylene or alkenylene) having from 1 to about 22 carbon atoms and two free carbon single bonds when L is 2. 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.

[0198] The TerminOx Supreme (Catalase Enzyme from Novozymes) as well as the Glucose Oxidase (enzyme) were used neat with hydrogen peroxide and not tested as part of any formulated composition. These mixtures were ca.1:1 as described in the Tables above.PATENT APPLICATION Docket No. P14677WO00-E12102WOU1

[0199] This initial screen was to assess combinations that provided an exotherm greater than 90°F when starting at a room temperature (approximately 67-70°F), which was set as an initial threshold (with the understanding that variations in the compositions and the ratios will impact the exotherm). For example, for milder soils a lower temperature increase may be sufficient, such as at least about 10°F, depending on its thermodynamic properties.

[0200] The initial temperature profile measurements of the binary mixtures on several substrates show proof of concept that the combinations of a multipart composition that includes in a first part at least one alkaline accelerant, at least one solvent, and an emulsifying surfactant when combined with a second part with a peroxygen compound co-accelerant result in exothermic reactions. It is appreciated from these initial results that the weight ratio of the first to the second part can be further modified to enhance a particular exothermic reaction by increasing the ratio of the second part with the peroxygen compound co- accelerant.

[0201] The bar graph depiction of the top exotherm generating multi-part compositions are shown in Figures 1-3. Figure 1 shows those combinations with temperatures greater than 90°F on a glass substrate. Of these, the combination of Glucose Oxidase (Glu-Ox) and 35% H2O2yielded an exothermic temperature of 157°F. This combination along with Exp8 and 35% H2O2 offers the potential of having sustainable and possible PPE free / minimum PPE offerings. Exp8 (Triethanolamine based) with Exp9 (Glycerol Carbonate based) are also suitable candidates of interest for future experimentation demonstrating alkaline accelerants in addition to alkali metal hydroxides.

[0202] Figure 2 shows combinations with temperatures greater than 90°F on a polypropylene substrate with increased temperature generation from combining Exp4 / 50% H2O2and Exp4 / 35% H2O2 (Monoethanolamine based). Further Figure 3 shows combinations with temperatures greater than 90°F on a 316 Stainless Steel substrate with increased temperature generation from combining Exp4 / 50% H2O2 and Exp4 / 35% H2O2 (Monoethanolamine based). Without being limited to a particular mechanism of action or theory of the invention it is appreciated that the nature of the substrate treated, namely the surface energy, impacts temperature of the exotherm of the multi-part composition. EXAMPLE 2

[0203] Further testing of Exp4 formulation described in Table 1A from Example 1 were tested on soiled 316 SS (stainless steel) surfaces as described in Table 3.PATENT APPLICATION Docket No. P14677WO00-E12102WOU1

[0205] The results of Test 1 on the 316 SS Coupons with baked on Spent Shortening (i.e. used repeatedly in the frying of foods) – Shortening / oil were overall positive. The soiled coupons had an initial Heavy / Almost cherry discoloration. These coupons were baked on fat soils depicting a polymerized soil which is known to be extremely challenging to remove. After the reaction of the mixture for the 114 seconds (1.9 minutes), the temperature increased to ca.163°F. This experiment penetrated and removed some of the baked- Spent Shortening – Shortening / oil. Additional dwell time and improved wetting were identified for further composition modifications to enhance formulation for more effective tenacious soil removal.

[0206] The results of Test 2 on the 316 SS Coupons with baked on Spent Shortening – Shortening / oil were overall positive with an improvement over Test 1. The soiled coupons had the same initial Heavy / Almost cherry discoloration as in Test 1. After the reaction of thePATENT APPLICATION Docket No. P14677WO00-E12102WOU1 mixture for the 187 seconds (3.1 minutes), the temperature increased to ca.180°F. This experiment penetrated and removed some of the baked- Spent Shortening – Shortening / oil. Additional dwell time and improved wetting were identified for further composition modifications to enhance formulation for more effective tenacious soil removal.

[0207] The results of Test 3 on the 316 SS Coupons with baked on Spent Shortening – Shortening / oil were overall positive with an improvement over Test 1. The soiled coupons had the same initial Heavy / Almost cherry discoloration as in Test 1. After the reaction of the mixture for the 130 seconds (2.2 minutes), the temperature increased to ca.142°F. This experiment penetrated and removed some of the baked- Spent Shortening – Shortening / oil. Additional dwell time and improved wetting were identified for further composition modifications to enhance formulation for more effective tenacious soil removal.

[0208] The results of Test 4 on the 316 SS Coupons with baked on Spent Shortening – Shortening / oil were overall positive with an improvement over Test 1. The soiled coupons had the same initial Heavy / Almost cherry discoloration as in Test 1. After the reaction of the mixture for the 120 seconds (2 minutes), the temperature increased to ca.187°F. This experiment resulted in little removal of the baked- Spent Shortening – Shortening / oil. From these results a formulation with greater than 1:1 Part A to Part B may be required for a monoethanolamine based formula as Part A. EXAMPLE 3

[0209] Further testing of Exp4 formulation described in Table 1A from Example 1 were tested on aluminum baking pan coupons, cut to three-fourth by five-inch (0.75” X 5”) sizes from a commercial deli department. The testing compared four drops of each respective control cleaner Control 1 (commercial), and Control 2 (commercial) as shown in Tables 4-5.

The treated portions of the coupon are shown in Figures 4A-4B, Left to Right with the treated portions outlined by the black markings.

[0213] The same stained coupons were then compared to cleaning results using Exp4 plus 35% H2O2and 50% H2O2. After the reaction of the Exp4 and the 35% H2O2mixture in a 0.6:1 ratio for 132 seconds (2.2 minutes), the temperature increased to ca.142°F. After the reaction of the Exp4 and the 50% H2O2mixture in a 1:1 ratio for 480 seconds (8 minutes), the temperature increased to ca.187°F. The treated areas are each shown in Figures 4C-4D, Left to Right for the respective coupons. The results showed that enahnced soil removal was achieved with the multi-part cleaning composition as described herien compared to the commercial controls.

[0214] Overall performance of Exp4 plus 35% hydrogen peroxide was better than the cleaner in Figures 4B although not as good as Control 1. Exp4 with 35% hydrogen (scored using the Roman Wallpaper Scoring Tool in an effort to increase surface area for enhanced penetration) and Exp4 with 50% hydrogen peroxide did not perform as good as Exp4 with 35% hydrogen peroxide but was better than the other two Control cleaners.PATENT APPLICATION Docket No. P14677WO00-E12102WOU1 EXAMPLE 4

[0215] Testing on coupons soiled with nail polish containing glitter were analyzed. The nail polish was applied to a 316 SS coupon and allowed to dry 10 – 20 minutes before treatment. As shown in Figure 5 Exp4 combined with 35% H2O2was used to remove the soils. The figure shows the chemistry was applied to the center of the stain after treatment after allowing the chemistry to dwell for approximately two minutes each for Part A and Part B, each section was rinsed under a stream of cold 5 grain water and gently wiped with a paper towel. The area in the middle of the stain shows the results of the applied treatment. EXAMPLE 5

[0216] Testing on coupons soiled with Spent Shortening – Shortening / oil (the soil as described in Example 3) were evaluated using Exp4 and hydrogen peroxide. A section of the coupon was scored using the Roman Wallpaper Scoring Tool before treating that section. The use of the scoring tool was intended to increase surface area of the soil for improved penetration of the adhesive. Part A - Added 10 drops (0.30 grams) of Exp4 to the coupon and allowed to dwell for 60 seconds (1.0 minute). Then Part B - Added 6 drops of 35% H2O2(0.60 grams) and allowed the mixture to react for 140 seconds (2.3 minutes). The temperature increased to ca.184°F. This experiment resulted in good removal of this tenacious soil, as shown in Figure 6. EXAMPLE 6

[0217] Presoak testing for tenacious soil removal was completed to evaluate removal of soils from soiled aluminum roasting sheet pan coupons cut to three-fourth by five-inch (0.75” X 5”) sizes using the Exp11-Exp15 as shown in Table 6.
