Description:
CROSS-REFERENCE 
     This application claims priority under 35 U.S.C. § 119 to provisional application U.S. Ser. No. 62/811,934 filed Feb. 28, 2019 entitled “STABILIZING SYSTEM FOR LAUNDRY EMULSIONS,” and U.S. Ser. No. 62/873,262 filed Jul. 12, 2019, entitled “STABILIZING SYSTEM FOR LAUNDRY EMULSIONS,” each of which is herein incorporated by reference in its entirety. 
    
    
     FIELD OF THE INVENTION 
     The application relates to an improved liquid detergent concentrate composition, which demonstrates improved stability while maintaining a preferred viscosity, and to a method for washing textiles. The liquid detergent composition can be provided as a concentrate or as a use solution. The liquid detergent composition in the form of the concentrate or the use solution is an emulsion of the type water-in-oil emulsion or oil-in-water emulsion dependent on the amounts of water and oil in the emulsion. 
     BACKGROUND OF THE INVENTION 
     Liquid detergents are known from the state of the art. Such detergents are, for example, described in U.S. Pat. No. 5,880,083, WO 2004/065535 A1, and WO 2004/041990 A1. One problem in the formulation of liquid detergent is to develop formulations that can be judged satisfactory regarding the performance perspective, namely that soil is sufficiently removed, the fabric is pleasantly soft and free of yellowing/fading, and the fabric is not damaged in the cleaning process. On the other hand the emulsions need to be sufficiently viscous and stable storage, so that even under temperature stress over several months, neither the viscosity collapses nor phase separation occurs. Some existing products separate during storage and are not readily redispersed. In some cases the product viscosity changes and it becomes either too thick to pour or so thin as to appear watery. Some clear products become cloudy and others gel on standing. 
     It is particularly challenging to stabilize highly alkaline emulsions while maintaining an ideal viscosity. A further challenge is added in creating a stabilized, highly alkaline emulsion which is cost-effective and easy to manufacture. 
     The document WO 2014/154244 discusses a liquid detergent composition comprising a stable emulsion. WO 2014/154244 utilizes a stabilizing system comprising a blend of two polymers, particularly an acrylic acid crosslinked copolymer (e.g. Carbopol®). However, the preparation and production of such a stabilizing system is less cost-effective. 
     Further, document WO 2007/101470 describes a liquid detergent composition which is storage-stable and shows a good washing performance. As nonionic surfactants, linear alkoxylated alcohols are used in the detergent composition. These are, for example, linear fatty alcohol ethoxylates having a C 13 -C 15  alkyl group and 7 EO units. These liquid detergent concentrate compositions according to the state of art comprised about 1 wt. % to about 70 wt. % of said alkoxylated fatty alcohol. These liquid detergent compositions contain solubilizers which are able to keep the components in solution and the resulting emulsion stable even over a longer storage time. This was achieved by the use of one or more cross-linked or partly cross-linked polyacrylic acids and/or polymethacrylic acids in the composition. These substances are used as thickener and stabilizer for a liquid detergent concentrate composition which represent an emulsion. These polyacrylic acid or polymethacrylic acid may be cross-linked or partly cross-linked with a polyalkenyl polyether compound as crosslinker. Those compounds are available under the trade name Carbopol® from Noveon. 
     A drawback of such existing compositions is the production process to introduce the cross-linked or partly cross-linked polyacrylic acid/polymethacrylic acid thickener and stabilizers into the emulsion. The production process of the emulsions of the state of art requires the use of a pre-mix to introduce the thickening polymer, i.e. the solid cross-linked or partly cross-linked polyacrylic acid/polymethacrylic acid, into the formula. This pre-mix is both expensive and time-consuming due to the nature of the addition, which also involves a milling step. Within the pre-mix, a powder eductor recirculates a liquid surfactant to which the powder polymer is added. This pre-mix is then added to the rest of the emulsion. 
     Surprisingly, the present application has found that an acrylic copolymer can reduce the cost of production and provide improved stabilization while maintaining viscosity. Beneficially, the cost-effective compositions of the application may be produced by using a pre-mix, or without requiring a pre-mix. 
     Accordingly, an object of the application is to provide a liquid detergent composition having improved stability, in particular having an emulsion which is stable for at least a year, and which provides improved or at last substantially similar cleaning performance as other existing liquid detergent compositions. 
     A further object of the application is to provide a liquid detergent composition which maintains an ideal viscosity. 
     A further object of the application is to provide a more cost-effective, stable, and viscous liquid detergent composition which may be prepared using a pre-mix or without requiring a pre-mix. 
     Other objects, advantages and features of the detergent compositions disclosed herein and use thereof will become apparent from the following specification taken in conjunction with the accompanying drawings. 
     BRIEF SUMMARY OF THE INVENTION 
     An advantage of the application is that the liquid detergent compositions can provide improved stability during storage, while maintaining a preferred viscosity, i.e. the viscosity does not collapse, become too viscous, etc. Another advantage of the application is that the compositions are cost-effective, and may be produced by using a pre-mix, or without requiring a pre-mix. 
     In an embodiment, the compositions of the application comprise stable liquid detergent compositions comprising an alkalinity source, wherein the alkalinity source is in a concentration of between about 1 wt. % and about 90 wt. %, a chelating/sequestering agent, wherein the chelating/sequestering agent is selected from the group consisting of a polymeric chelating/sequestering agent, an aminocarboxylic acid or salt thereof, gluconic acid or a salt thereof, or a mixture thereof an acrylic copolymer thickening agent; at least one nonionic surfactant; and at least one whitening agent; wherein the pH of the composition is between about 9 and about 14; and wherein the composition comprises a stable emulsion having a water phase and an oil phase. 
     In a more preferred embodiment, the chelating/sequestering agent comprises a polymeric chelating agent, an aminocarboxylic acid or salt thereof, and gluconic acid or salt thereof. Still more preferably, polymeric chelating agent comprises a polycarboxylic acid or salt thereof. 
     In a preferred embodiment, the optical brightener comprises one or more stilbene derivatives. In a most preferred embodiment, the optical brighter comprises a 4,4′-distyryl biphenyl derivative, a derivative of bis(triazinyl)amino-stilbene, a bisacylamino derivative of stilbene, a triazole derivative of stilbene, a triazine derivative of stilbene, an oxadiazole derivative of stilbene, an oxazole derivative of stilbene, a styryl derivative of stilbene, or a mixture thereof. 
     In some aspects, the liquid detergent composition is provided as a concentrate. In an embodiment, the composition exhibits less than 10% phase separation for at least one year. 
     A preferred embodiment is also found in a method of washing textiles comprising providing the liquid detergent composition and washing the textiles in an institutional or a household washing machine; wherein the liquid detergent composition comprising an alkalinity source, wherein the alkalinity source is in a concentration of between about 1 wt. % and about 90 wt. %, a chelating/sequestering agent, wherein the chelating/sequestering agent is selected from the group consisting of a polymeric chelating/sequestering agent, an aminocarboxylic acid or salt thereof, gluconic acid or a salt thereof, or a mixture thereof; an acrylic copolymer thickening agent; at least one nonionic surfactant; and at least one whitening agent; wherein the pH of the composition is between about 9 and about 14; and wherein the composition comprises a stable emulsion having a water phase and an oil phase.

     The liquid detergent concentrate composition according to the application is a stable emulsion which exhibits less than 10% phase separation when being stored. The emulsion is also stable at lower temperatures, for example −5° C. If the emulsion is frozen at temperatures below −10° C. and melted thereafter, the emulsion is formed again without stirring the composition. This is particularly important when the emulsion is stored outside for example in wintertime where outside temperatures are lower than −5° C. Even under these extreme conditions the liquid detergent concentrate composition according to the application is a stable emulsion, does not separate and recovers completely at ambient temperatures. 
     Usually the detergent composition is made available as a concentrate and/or shipped or stored as a concentrate in order to avoid the expense associated with shipping and/or storing a composition containing a large amount of water. The concentrate is then normally diluted at the location of use to provide a use solution. Furthermore, it is also possible that the concentrate is first diluted to provide a more dilute concentrate and then a ready-to-use composition is prepared by further diluting the diluted concentrate. 
     Beneficially, the detergent compositions are stable, flowable emulsions which do not undergo phase separation during storage or when exposed to highly different temperature ranges. In an aspect, the detergent compositions do not undergo phase separation at room temperature storage for a period of at least 6 months. In an aspect, the detergent compositions do not undergo phase separation at 40° C.-50° C. and/or refrigeration between 2° C.-10° C. storage for a period of at least 8 weeks (which is also illustrative of room temperature stability of 6 months). As referred to herein, a lack of phase separation is confirmed by less than 10%, preferably less than 5% separation of the detergent composition over the period of time and under defined temperature conditions. 
     Viscosity 
     In a preferred embodiment, the liquid detergent concentrate compositions have a viscosity range of from about 1 mPas to about 3000 mPas, 1 mPas to 1500 mPas, 1 mPas to 1000 mPas, at 20° C. measured at 20 revolutions per minute on a Brookfield RVT viscosimeter with spindle #2. The liquid detergent concentrate compositions according to the application preferably has a viscosity in the range of from 300 mPas to 3000 mPas, 300 mPas to 1500 mPas, 300 mPas to 1000 mPas, further preferred 300 mPas to 900 mPas, still further preferred 350 mPas to 900 mPas, and most preferred from 400 mPas to 700 mPas at 20° C. measured at 20 revolutions per minute on a Brookfield RVT viscosimeter with spindle no. 2. This low viscosity allows to pump the liquid detergent concentrate by using standard pumping devices and it is not necessary to use specific pumping devices for high-viscous liquids. Because of the low viscosity of the product, it can be dosed by usual standard peristaltic pumps which are much cheaper than pumps for higher viscous fluids. 
     Source of Alkalinity 
     The liquid detergent composition comprises one or more alkalinity sources in an amount of about 1 wt. % to about 90 wt. %, preferably from about 10 to about 30 wt. %. The source of alkalinity can be any source of alkalinity that is compatible with the other components of the detergent composition. Exemplary sources of alkalinity include alkali metal hydroxides, alkali metal carbonates, alkali metal silicates, alkali metal salts, phosphates, amines, and mixtures thereof, preferably alkali metal hydroxides including sodium hydroxide, potassium hydroxide, and lithium hydroxide or mixtures thereof, and most preferred is sodium hydroxide and/or potassium hydroxide. 
     The liquid detergent concentrate composition according to the application may be provided as a highly alkaline concentrate or as a use solution based on the quantity of the alkalinity source. The alkalinity source controls the pH of the resulting solution when water is added to the detergent composition to form a use solution. The pH of the use solution must be maintained in the alkaline range in order to provide sufficient detergency properties. Further, the pH of the use solution is also useful for an optimized reduction in the germs count, such as bacteria, fungi, virus and spores, of the laundry washed with the detergent composition of the application, preferably in combination with the second component of the application. After the addition of the second component, the bleach base or peracid compound, the pH of the composition may be reduced. In a preferred embodiment, the pH of the use solution is at least 8, and is between approximately 9 and approximately 14. Particularly, the pH of the use solution is between about 10 and about 14. More particularly, the pH of the use solution is between about 11 and about 14. In a particularly preferred embodiment, the pH of the use solution is from about 12 to about 13.5 and the pH of the concentrate is from about 13 to 14. 
     Exemplary alkali metal hydroxides include sodium hydroxide, potassium hydroxide, and lithium hydroxide. However, most preferred is sodium hydroxide. The source of alkalinity, preferably an alkali metal hydroxide, can be included in a variety of forms, including for example in the form of solid beads, dissolved in an aqueous solution or a combination thereof. Alkali metal hydroxides are commercially available as pellets or beads having a mix of particle sizes, or as an aqueous solution having an active concentration between about 20% and about 90% in the solution, preferred active concentrations in a solution, include, but are not limited to, about 45%, about 50%, and about 73% alkalinity in the alkaline solution. 
     Exemplary alkali metal salts include without limitation sodium carbonate, trisodium phosphate, potassium carbonate, and mixtures thereof. Exemplary phosphates include without limitation sodium pyrophosphate, potassium pyrophosphate, and mixtures thereof. Exemplary amines include without limitation alkanolamine selected from the group comprising triethanolamine, monoethanolamine, diethanolamine, and mixtures thereof. 
     In some embodiments, the alkalinity source is included in the detergent composition at an amount of at least about 1 wt. % to about 90 wt. %, about 1 wt. % to about 80 wt. %, about 1 wt. % to about 70 wt. %, about 1 wt. % to about 60 wt. %, about 1 wt. % to about 50 wt. %, about 10 wt. % to about 50 wt. %, about 10 wt. % to about 40 wt. %, or about 20 wt. % to about 40 wt. %. In certain cleaning contexts, it is preferable to reduce the amount of alkalinity employed in a detergent composition. However, this must be balanced by the need to keep the pH of detergent compositions sufficiently high provide the desired detergency and cleaning. With that in mind, it has been found that the compositions can still be made sufficiently alkaline (e.g., a pH of between about 9 and 14, more preferably between about 10 and 14, most preferably between about 12 and 14) with the use of lesser amounts of alkalinity. In such an embodiment, the composition has between about 1 wt. % and about 40 wt. %, more preferably between about 5 wt. % and about 30 wt. %, most preferably between about 10 wt. % and about 25 wt. %. It should be understood that the amounts recited are in weight percentage and not based on active concentration of hydroxide. For example, 10-25 wt. % of a 50% active alkalinity source will have 5-12.5% active concentration of alkalinity. Further, we have found that in some embodiments a certain level of alkalinity source benefits the stability of the compositions. In such an embodiment, it is preferred that there be at least about 5% active concentration of alkalinity source, more preferably at least about 8% active concentration of alkalinity source, most preferably at least about 10% active concentration of alkalinity source. 
     Nonionic Surfactants 
     The liquid detergent concentrate composition preferably comprises at least one nonionic surfactant, present from about 1 to about 70 wt. % of a nonionic surfactant. In preferred embodiments the compositions of the present application include about 5 to about 30 wt. %, further preferred about 5 to 20 wt. % and particularly preferred about 5 to about 18 wt. % of a nonionic surfactant. 
     Nonionic surfactants suitable for use with the compositions of the present application include synthetic or natural alcohols that are alkoxylated (with ethylene and/or propylene and/or butylene oxide) to yield a variety of C 6 -C 24  alcohol ethoxylates and/or propoxylates and/or butoxylates (preferably C 5 -C 14  alcohol ethoxylates and/or propoxylates and/or butoxylates having 1 to 20 alkylene oxide groups (preferably 2 to 20 alkylene oxide groups); C 5 -C 24  alkylphenol ethoxylates (preferably C 8 -C 10  alkylphenol ethoxylates) having 1 to 100 ethylene oxide groups (preferably about 12 to about 20 ethylene oxide groups); and C5-C24 alkylpolyglycosides (preferably C 5 -C 20  alkylpolyglycosides) having 1 to 20 glycoside groups (preferably 9 to 20 glycoside groups). 
     Suitable alkoxylated surfactants for use as surfactants include EO/PO block copolymers, such as the Pluronic® and reverse Pluronic® surfactants; alcohol alkoxylates, such as Dehypon® LS-54 (R-(EO) 5 (PO) 4 ); wherein R represents a linear or branched fatty alcohol residue) and Dehypon® LS-36 (R-(EO) 3 (PO) 6 ; wherein R represents a linear or branched fatty alcohol residue); and capped alcohol alkoxylates, such as Plurafac® LF221 and Tegoten® EC11; mixtures thereof, or the like. More specifically the composition of the present application can include alkoxylated primary or secondary alcohol having from 6 to 24, preferably 6 to 22, more preferred 8 to 18 carbon atoms reacted with from 2 to 18 moles of ethylene, and/or propylene, and/or butylene oxide. In a preferred embodiment the nonionic has from 3 to 18 moles of alkylene oxide, in another preferred embodiment from 3 to 10 moles of ethylene oxide, and in yet another preferred embodiment 7 to 8 moles of EO. These materials are commercially available and well-known nonionic surfactants. The following materials are useful: lauryl alcohol ethoxylated with 3 moles of ethylene oxide (EO), coco alcohol ethoxylated with 3 moles EO, stearyl alcohol ethoxylated with 5 moles EO, mixed C 12 -C 15  alcohol ethoxylated with 7 moles EO, mixed secondary C 11 -C 15  alcohol ethoxylated with 7 moles EO, mixed C 9 -C 11  linear alcohol ethoxylated with 6 moles EO and the like. 
     In preferred embodiment the nonionic has from 8 to 15 carbon atoms in the alkyl group. When this alkyl group is used a nonionic is the mixed C 12 -C 15  alcohol ethoxylated with 7 moles EO. In a further preferred embodiment it comprises the alcohol alkoxylates, particularly the alcohol ethoxylates and propoxylates, especially the mixed ethoxylates and propoxylates, particularly with 3-7 oxyethylene (EO) units and 3-7 oxypropylene (PO) units such as the alcohol Dehypon® available from BASF Corporation, having 5 EO units and 4 PO units. In another preferred embodiment it comprises the alcohol alkoxylates, particularly C 12 -C 15  alcohol (e.g. mixed C 13 /C 15  alcohol, iso-tridecanol), particularly with 2-20 oxyethylene (EO) units, preferably with 5-12 oxyethylene (EO) units, further preferred with 5-10 oxyethylene (EO) units, in particular with 7 or 8 oxyethylene (EO) units, such as the Lutensol® TO , particularly TO 8, available from BASF and Lutensol® AO, such as AO7 and AO3, available from BASF. 
     Suitable alkoxylated surfactants for use as surfactants further include a guerbet alcohol ethoxylate of the formula R 6 —(OC 2 H 4 ) m —OH, wherein R 6  is a branched C 9  to C 20  alkyl group, preferably a branched C 9  to C 18  alkyl group, further preferred a branched C 9 -C 15  alkyl group, more preferred a branched C 9 -C 11  alkyl group, most preferred a branched C 10  alkyl group and m is from 2 to 10, preferably 2 to 6. Such guerbet alcohols are available, for example, under the trade name Lutensol® XP or M from BASF or Eutanol® G from BASF. 
     The guerbet reaction is a self-condensation of alcohols by which alcohols having branched alkyl chains are produced. The reaction sequence is related to the Aldol condensation and occurs at high temperatures under catalytic conditions. The product is a branched alcohol with twice the molecular weight of the reactant minus a mole of water. The reaction proceeds by a number of sequential reaction steps. At first the alcohol is oxidized to an aldehyde. Then Aldol condensation takes place after proton extraction. Thereafter the aldol product is dehydrated and the hydrogenation of the allylic aldehyde takes place. 
     These products are called guerbet alcohols and are further reacted to the nonionic alkoxylated guerbet alcohols by alkoxylation with i.e. ethylene oxide or propylene oxide. The ethoxylated guerbet alcohols have a lower solubility in water compared to the linear ethoxylated alcohols with the same number of carbon atoms. Therefore the exchange of linear fatty alcohols by branched fatty alcohols makes it necessary to use good solubilizers which are able to keep the guerbet alcohol in solution and the resulting emulsion stable even over a longer storage time. 
     Additional Surfactants 
     According to some embodiments, the composition may further comprise additional surfactants, including without limitation one or more anionic, zwitterionic, cationic, and/or amphoteric surfactants. Where utilized, the one or more additional surfactants may be present in the composition from about 0 wt. % to about 90 wt. %, inclusive of all integers between. 
     Anionic surface-active substances which are categorized as such 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) can also be employed in certain embodiments. 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. 
     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 5 -C 17  acyl-N-(C 1 -C 4  alkyl) and —N-(C 1 -C 2  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 1 to 6 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 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. 
     Suitable anionic surfactants include alkyl or alkylaryl ethoxy carboxylates of the following formula: 
       R—O—(CH 2 CH 2 O) n (CH 2 ) m —CO 2 X   (3)
 
     in which R is a C 8  to C 22  alkyl group or 
     
       
         
         
             
             
         
       
     
     in which R 1  is a C 4 -C 16  alkyl group; n is an integer of 1-20; m is an integer of 1-3; 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 4 to 10 and m is 1. In some embodiments, R is a C 8 -C 16  alkyl group. In some embodiments, R is a C 12 -C 14  alkyl group, n is 4, and m is 1. 
     In other embodiments, R is 
     
       
         
         
             
             
         
       
     
     and R 1  is a C 6 -C 12  alkyl group. In still yet other embodiments, R 1  is a C 9  alkyl group, n is 10 and m is 1. 
     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 C 12-13  alkyl polyethoxy (4) carboxylic acid (Shell Chemical), and Emcol CNP-110, a C 9  alkylaryl polyethoxy (10) carboxylic acid (Witco Chemical). Carboxylates are also available from Clariant, e.g. the product Sandopan® DTC, a C 13  alkyl polyethoxy (7) carboxylic acid. 
     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 8 to 18 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 “Surfactant Encyclopedia” Cosmetics &amp; Toiletries, Vol. 104 (2) 69-71 (1989), which is herein incorporated by reference in its entirety. The first class includes acyl/dialkyl ethylenediamine derivatives (e.g. 2-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, 2-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 application generally have the general formula: 
     
       
         
         
             
             
         
       
     
     wherein R is an acyclic hydrophobic group containing from about 8 to 18 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 2 , in which R═C 8 -C 18  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(2-carboxyethyl) alanine. Examples of commercial N-alkylamino acid ampholytes having application in this application include alkyl beta-amino dipropionates, RN(C 2 H 4 COOM) 2  and RNHC 2 H 4 COOM. In an embodiment, R can be an acyclic hydrophobic group containing from about 8 to about 18 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 8 to 18 (e.g., 12) carbon atoms. Such a surfactant can also be considered an alkyl amphodicarboxylic acid. These amphoteric surfactants can include chemical structures represented as: C 12 -alkyl-C(O)—NH—CH 2 —CH 2 —N + (CH 2 —CH 2 —CO 2 Na) 2 —CH 2 —CH 2 —OH or C 12 -alkyl-C(O)—N(H)—CH 2 —CH 2 —N + (CH 2 —CO 2 Na) 2 —CH 2 —CH 2 —OH. Disodium cocoampho dipropionate is one suitable amphoteric surfactant and is commercially available under the tradename Miranol™ FBS from Rhodia Inc., Cranbury, N.J. 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.J. 
     A typical listing of amphoteric 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). 
     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 8 to 18 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: 
     
       
         
         
             
             
         
       
     
     wherein R 1  contains an alkyl, alkenyl, or hydroxyalkyl radical of from 8 to 18 carbon atoms having from 0 to 10 ethylene oxide moieties and from 0 to 1 glyceryl moiety; Y is selected from the group consisting of nitrogen, phosphorus, and sulfur atoms; R 2  is an alkyl or monohydroxy alkyl group containing 1 to 3 carbon atoms; x is 1 when Y is a sulfur atom and 2 when Y is a nitrogen or phosphorus atom, R 3  is an alkylene or hydroxy alkylene or hydroxy alkylene of from 1 to 4 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: 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 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: 
     
       
         
         
             
             
         
       
     
     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 12-14  acylamidopropylbetaine; C 8-14  acylamidohexyldiethyl betaine; 4-C 14-16  acylmethylamidodiethylammonio-1-carboxybutane; C 16-18  acylamidodimethylbetaine; C 12-16  acylamidopentanediethylbetaine; and C 12-16  acylmethylamidodimethylbetaine. 
     Sultaines useful in the present application include those compounds having the formula (R(R 1 ) 2 N + R 2 SO 3− , in which R is a C 6 -C 18  hydrocarbyl group, each R 1  is typically independently C 1 -C 3  alkyl, e.g. methyl, and R 2  is a C 1 -C 6  hydrocarbyl group, e.g. a C 1 -C 3  alkylene or hydroxyalkylene group. 
     A typical listing of zwitterionic 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). Each of these references is herein incorporated in their entirety. 
     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. 
     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 simplest cationic amines, amine salts and quaternary ammonium compounds can be schematically drawn thus: 
     
       
         
         
             
             
         
       
     
     in which, R represents a long alkyl chain, R′, R″, and R″′ may be either long alkyl chains or smaller alkyl or aryl groups or hydrogen and X represents an anion. The amine salts and quaternary ammonium compounds are preferred for practical use in this application due to their high degree of water solubility. 
     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 “Surfactant Encyclopedia”,  Cosmetics  &amp;  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. 
     Cationic surfactants useful in the compositions of the present application include those having the formula R 1   m R 2   x Y L Z wherein each R 1  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: 
     
       
         
         
             
             
         
       
     
     or an isomer or mixture of these structures, and which contains from about 8 to 22 carbon atoms. The R 1  groups can additionally contain up to 12 ethoxy groups. m is a number from 1 to 3. Preferably, no more than one R 1  group in a molecule 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 from 1 to 4 carbon atoms or a benzyl group with no more than one R 2  in 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. Y is can be a group including, but not limited to: 
     
       
         
         
             
             
         
       
     
     or a mixture thereof. Preferably, L is 1 or 2, with the Y groups being separated by a moiety selected from R 1  and R 2  analogs (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. 
     Chelants, Sequestrants, Builders, Water Conditioning Polymers 
     The compositions may also include one or more chelating/sequestering agent(s) or builders. In general, a sequestrant chelating agent or builder is a molecule capable of coordinating (i.e., binding) the metal ions commonly found in natural water to prevent the metal ions from interfering with the action of the other detersive ingredients of a detergent composition. For a further discussion of chelating agents/sequestrants, see Kirk Othmer, Encyclopedia of Chemical Technology, Third Edition, volume 5, pages 339-366 and volume 23, pages 319-320. In some embodiments, a phosphonate can be included and is preferred. However, in other embodiments, it is preferred that the compositions be free of phosphonates, and other phosphorus containing compounds; in such an embodiment, the chelating/sequestering agent is preferably a non-phosphorus containing aminocarboxylate, gluconic acid salt, polymeric chelating agent, or combination thereof. 
     Suitable sequestrants include, but are not limited to, organic chelating compounds that sequester metal ions in solution, particularly transition metal ions. Such sequestrants include organic amino- or hydroxy-polyphosphonic acid complexing agents (either in acid or soluble salt forms), carboxylic acids (e.g., polymeric polycarboxylate), hydroxycarboxylic acids, aminocarboxylic acids, or heterocyclic carboxylic acids, e.g., pyridine-2,6-dicarboxylic acid (dipicolinic acid). 
     Exemplary commercially available chelating/sequestering agent(s) include, but are not limited to a gluconic acid salt (such as sodium gluconate (e.g. granular)) and sodium tripolyphosphate (available from lnnophos); the aminocarboxylate Trilon® M available from BASF; Versene® 100, Low NTA Versene®, Versene® Powder, and Versenol® 120 all available from Dow; Dissolvine® D-40 and GL-38 available from Akzo; and sodium citrate. In a most preferred embodiment, the chelating/sequestering agent comprises sodium gluconate. 
     In preferred embodiments of the compositions organic chelating/sequestering agent(s) may be used. Organic chelating/sequestering agent(s) include both polymeric and small molecule chelating/sequestering agent(s). Organic small molecule chelating/sequestering agent(s) are typically organocarboxylate compounds or organophosphate chelating/sequestering agent(s). Polymeric chelating/sequestering agent(s) commonly include polyanionic compositions such as polyacrylic acid compounds, carboxy-methylated polyethyleneimine compounds, and mixtures thereof. In a most preferred embodiment, the detergent composition comprises a polymeric chelating/sequestering agent.

     Optical Brighteners and Whitening Agents 
     The detergent compositions may include an optical brightener, also referred to as a fluorescent whitening agent or a fluorescent brightening agent. Brighteners are added to laundry detergents to replace whitening agents removed during washing and to make the clothes appear cleaner. Optical brighteners may include dyes that absorb light in the ultraviolet and violet region (usually 340-370 nm) of the electromagnetic spectrum, and re-emit light in the blue region (typically 420-470 nm). These additives are often used to enhance the appearance of the color of a fabric, causing a perceived “whitening” effect, making materials look less yellow by increasing the overall amount of blue light reflected. 
     Fluorescent compounds belonging to the optical brightener family are typically aromatic or aromatic heterocyclic materials often containing a condensed ring system. A feature of these compounds is the presence of an uninterrupted chain of conjugated double bonds associated with an aromatic ring. The number of such conjugated double bonds is dependent on substituents as well as the planarity of the fluorescent part of the molecule. Most brightener compounds are derivatives of stilbene or 4,4′-diamino stilbene, biphenyl, five membered heterocycles (triazoles, oxazoles, imidazoles, etc.) or six membered heterocycles (naphthalamides, triazines, etc.). The choice of optical brighteners for use in compositions will depend upon a number of factors, such as the type of composition, the nature of other components present in the composition, the temperature of the wash water, the degree of agitation, and the ratio of the material washed to the tub size. The brightener selection is also dependent upon the type of material to be cleaned, e.g., cottons, synthetics, etc. Because most laundry detergent products are used to clean a variety of fabrics, the detergent compositions may contain a mixture of brighteners which are effective for a variety of fabrics. Further, it can be common to employ different temperatures based on the types of fabrics to be washed, with this in mind, it is preferable to an optical brightener effective in low temperature and high temperature wash cycles. It is of course necessary that the individual components of such a brightener mixture be compatible. In a preferred embodiment, the detergent composition contains at least two optical brighteners. 
     Examples of suitable optical brighteners are commercially available and will be appreciated by those skilled in the art. At least some commercial optical brighteners can be classified into subgroups, including, but are not limited to derivatives of stilbene, pyrazoline, carboxylic acid, methinecyanines, dibenzothiophene-5,5-dioxide, azoles, 5- and 6-membered-ring heterocycles, and other miscellaneous agents. Examples of particularly suitable optical brightening agents include, but are not limited to: distyryl biphenyl disulfonic acid sodium salt, cyanuric chloride/diaminostilbene disulfonic acid sodium salt. Examples of suitable commercially available optical brightening agents include, but are not limited to: Tinopal® 5 BM-GX, Tinopal® CBS-CL, Tinopal® CBS-X, Tinopal® DMS-X, Tinopal® DMA-X, and Tinopal® AMS-GX, available from BASF, and Optiblanc MTB available from 3V Sigma USA. Examples of optical brighteners are also disclosed in “The Production and Application of Fluorescent Brightening Agents,” M. Zahradnik, Published by John Wiley &amp; Sons, New York (1982), the disclosure of which is incorporated herein by reference. Suitable stilbene derivatives include, but are not limited to derivatives of bis(triazinyl)amino-stilbene, bisacylamino derivatives of stilbene, triazole derivatives of stilbene, triazine derivatives of stilbene, oxadiazole derivatives of stilbene, oxazole derivatives of stilbene, and styryl derivatives of stilbene. 
     One or more optical brighteners may be used in the compositions. In some embodiments, optical brighteners are included in the compositions, individually or in sum, at an amount of from about 0.01 to about 5 wt. %, from about 0.1 wt. % to about 4 wt. %, from about 0.15 to about 3 wt. %, or from about 0.2 to about 2 wt. %. 
     Additional Functional Ingredients 
     The compositions may include additional functional ingredients. Additional functional ingredients suitable for inclusion in the compositions include, but are not limited to, soil antiredeposition agents, antifoam agents, low foaming surfactants, defoaming surfactants, pigments and dyes, softening agents, anti-static agents, anti-wrinkling agents, dye transfer inhibition/color protection agents, odor removal/odor capturing agents, soil shielding/soil releasing agents, ultraviolet light protection agents, fragrances, sanitizing agents, disinfecting agents, water repellency agents, insect repellency agents, anti-pilling agents, souring agents, mildew removing agents, allergicide agents, and mixtures thereof. 
     In some embodiments, the additional functional ingredient or ingredients is formulated in the compositions. In other embodiments, the additional functional ingredient or ingredients is added separately during a cleaning process. 
     Color Stabilizing Agent 
     The compositions optionally include a color stabilizing agent. A color stabilizing agent can be any component that is included to inhibit discoloration or browning of the composition. In some embodiments, a color stabilizing agent may be included in the compositions at an amount of from about 0.01 wt. % to about 5 wt. %, from about 0.05 wt. % to about 3 wt. %, and from about 0.10 wt. % to about 2 wt. %. 
     Antiredeposition Agent 
     The compositions may include antiredeposition agents. Without wishing to be bound by any particular theory, it is thought that antiredeposition agents aid in preventing loosened soil from redepositing onto cleaned fabrics. Antiredeposition agents may be made from complex cellulosic materials such as carboxymethylcellulose (CMC), or synthetic materials such as polyethylene glycol and polyacrylates. In other embodiments, polyphosphate builders may be included as an antiredeposition agent. 
     Bleaching Composition 
     As the liquid detergent concentrate composition is preferably used as a detergent for institutional and industrial washing the liquid detergent concentrate composition as such does not contain any bleaching agents. In institutional and industrial washing processes the bleaching agent is normally dosed separately from the detergent. Only in powder household detergents bleaching agents are present. The present application therefore also provides a system comprising a first component and a second component, wherein the first component is represented by the liquid detergent concentrate according to the present application and the second component is containing a bleaching composition. 
     In some aspects, the bleaching compositions include at least one oxidizing agent. The bleaching composition can include any of a variety of oxidizing agents, for example, hydrogen peroxide and/or any inorganic or organic peroxide or peracid. The oxidizing agent can be present at an amount effective to convert a carboxylic acid to a peroxycarboxylic acid. In some embodiments, the oxidizing agent can also have antimicrobial activity. In other embodiments, the oxidizing agent is present in an amount insufficient to exhibit antimicrobial activity.

     Viscosity was assessed using a Brookfield viscometer, which measures viscosity through a spring using a cylinder rotating in the fluid sample. The torque required to turn the cylinder in the liquid is a function of the liquid&#39;s viscosity. Using a digital viscometer, the instrument was leveled, turned on, and zeroed. A sample of the composition was then transferred into an appropriately sized beaker. The spindle of the viscometer was then placed into the sample, and both were attached to the viscometer. Appropriate height and speed were selected. The viscometer was then run until the reading stabilized, generally about one minute. Viscosity was then recorded in milli Pascal seconds (mPas). Viscosity was considered suitable if the viscosity was less than 1000 mPas. 
     The compositions were additionally subjected to a storage test for liquid detergents. According to this test method, the storage behavior of samples of the compositions were evaluated at a range of temperatures (including room temperature), and in varying light conditions (i.e. daylight and the dark). The liquid compositions were kept for three months at −5° C., 5° C., room temperature, and 40° C. Additionally, the compositions were subjected to three freeze-thaw cycles, wherein the sample was frozen at −5° C. and thawed at 40° C. The samples were visually assessed twice a month, recording appearance including gelation, precipitation, flocculation, turbidity, phase separation, and color. 
     Phase separation was measured in millimeters based on a measurement of the bottom of the beaker to the top of the separated later, and the bottom of the beaker to the total height of the sample. recorded and expressed as a percentage of the total sample content, according to the formula: 
       % Separation=(precipitation (cm)/total level (cm))*100 
     Separation, such as precipitation, phase separations, etc. were deemed acceptable if the percent separation was not greater than 10% within the three-month storage period. The results of these tests are shown in Tables 4 and 5.

     These data show excellent storage capability across a wide range of temperature conditions. Separation was at most 2.2%, well below the 10% threshold of acceptability. Further, viscosity was no greater than 858 mPas, again well below the 1000 mPas threshold of acceptability. 
     Example 3 
     To further evaluate the impact of the acrylic copolymer thickener, compositions were prepared with increasing concentrations of the thickener, according to Table 6. The compositions were then evaluated using the procedure described in Example 2.

     Table 8 shows that Formulations A and B achieve the desired viscosity, as none of the compositions had a viscosity in excess of 1000 mPas. These results show that the compositions of the present application successfully achieve a desirable level of stability while maintaining a preferred viscosity. 
     Example 4 
     The compositions of the application were also prepared using a premix comprising the acrylic copolymer thickener. A premix may be used to further facilitate uniformity of the liquid composition, i.e. minimizing any lumps or inconsistencies in the materials. The compositions were prepared as shown in Table 9. The compositions were then evaluated using the procedure described in Example 2.

     Table 11 shows that Formulations C-D achieve the desired viscosity, as none of the compositions had a viscosity in excess of 1000 mPas. These results show that the compositions of the present application successfully achieve a desirable level of stability while maintaining a preferred viscosity. 
     Example 5 
     A detergent concentrate composition of the application was further evaluated for stability and viscosity. The detergent concentrate compositions were prepared according to Table 12, utilizing an acrylic copolymer as thickener for assessing impact on stability and viscosity of the concentrated detergent composition (emulsion), which was added to a premix of about 14% Rheosolve with about 86% water. Further, the composition of the application was formulated without phosphonate to provide a phosphonate-free composition, and formulated with a lower concentration of alkalinity.

     The composition as shown in Table 12 was compared against a comparative commercially available laundry detergent emulsion composition, Commercial Detergent A, which contains a phosphonate-based chelating agent, and a high molecular weight crosslinked polyacrylic acid polymer for the thickener. The compositions were then evaluated using the procedures described in Example 2 for analyzing both stability and viscosity. The results of the degree of separation test and the Brookfield viscosity analysis are shown in Tables 13 and 14, respectively.

     Table 14 shows that both Formulation E and Commercial Detergent A achieved the desired viscosity, as none of the compositions had a viscosity in excess of 1000 mPas. However, as shown in the table, Formulation E was able to achieve much lower viscosity than the commercially available detergent composition. These results show that the compositions of the present application successfully achieve a desirable level of stability while maintaining a preferred viscosity. 
     Example 6 
     The detergency efficacy of a single application of detergent composition was evaluated for the composition of the application in comparison to a comparative commercially available laundry detergent emulsion composition. Artificial stains were manually produced on fabric swatches and added into a centrifugal washing machine with the addition of a full load of soiled or clean laundry (100% polyester). The categories of soils evaluated included (1) fat/pigment soiling, (2) enzymatic stains, and (3) bleachable stains. Examples of fat pigment soils included lanolin, sebum, olive oil, mineral oil, used motor oil, make-up, and lipstick. Examples of enzymatic stains included blood, milk, cocoa milk, tomato beef sauce, porridge, vegetable oil, and starch. Examples of bleachable stains included tea, red wine, coffee, and black currant juice. The soiled test fabrics were added to the laundry to be washed. 
     The compositions evaluated were Formulation E and Commercial Detergent A from Example 5. The wash process utilized 0.9 mL/L of the detergent compositions and 0.7 mL/L of a peracetic acid bleach product. The test fabrics were washed for a time period of 12 minutes, at a temperature of about 60° C., and a pH level of about 9. 
     The test fabrics were evaluated by measuring remission values for the three categories of soils described above through an observation monitor. The remission value represents the amount of light transmission through the fabric swatch after one wash cycle. Therefore, the higher the remission value, the more soil that has been washed off. The average remission percentage value for each of the categories of soils evaluated are shown in Table 15. The goal is to have as high a remission value as possible and for purposes of this study to achieve about the same (or better) performance for the test formulation in comparison to an existing commercial detergent.

     As shown in Table 15, Formulation F and Commercial Detergent A demonstrated very similar remission values for all three categories of soils evaluated. Therefore, the results demonstrate that the composition of the present application is comparable in detergency efficacy when compared to a phosphonate-based detergent composition on a variety of types of soils. 
     Example 7 
     A detergent concentrate composition of the application was further evaluated for its fabric brightening properties as compared to a comparative commercially available laundry detergent emulsion composition. The whiteness degrees of various fabrics were measured with a UV light after 25 wash cycles. The fabrics evaluated included 100% cotton, 65% Cotton (CO)/35% Polyester (PES), and 50% cotton/50% polyester. The detergent compositions evaluated included Formulation E and Commercial Detergent A from Example 5. The whiteness evolution was calculated by measuring the reflectance of the swatches before and after the 25 wash cycles were performed. The reflectance values were measured with a Ganz-Griesser whiteness index which is measured in reflectance under UV light. As the measurement is done with UV, the measured whiteness degree is directly influenced by the fluorescence of the optical brightener and hence can be seen as a measure of the efficiency of the detergent and optical brightener. The results of the whiteness degree are shown in Table 16. Further, a ratio of the optical brighteners present in the two compositions are shown in Table 16 as well.

     As shown in Table 16, the whiteness degree (with UV) between Formulation E and Commercial Detergent A are comparable. The results demonstrate that the optical brightener mixture utilized in Formulation E (DMS-X and Optiblanc MTB) of the present application is more efficient than the brightener mixture of Commercial Detergent A (Tinopal CBS-X and DMS-X as essentially the same results were achieved with a lower effective concentration based on the 1:0.8 ratio employed. Based on these results, it is expected that if used at the same concentration Formulation E would outperform the existing commercially available detergent. Further, as both compositions contained the DMS-X, it appears the improvement in the whiteness degree is due to the inclusion of the Optiblanc (a triazine derivative of stilbene) and the removal of DMS-X (a disulfonic acid containing stilbene derivative). 
     The detergent compositions were further evaluated for their fabric whitening properties in the presence of a mixture of heavy metals. The addition of the heavy metals tested the efficacy of a gluconate-based chelating agent in Formulation E versus a phosphonate-based chelating agent in Commercial Detergent A. A mixture of heavy metals comprising iron, copper, and manganese were added to each wash cycle. The results of the whiteness degree are shown in Table 17 after 10 wash cycles. Here, the whiteness degree is a direct measure of the complexation capacity of the detergent compositions, as insufficient complexation would lead to yellowing of the fabrics and decrease of the whiteness degree.

     As shown in Table 17, the detergent composition of the present application demonstrated comparable or higher whiteness degree values after 10 washes compared to the commercial composition. This demonstrates the efficacy of the gluconate-based chelating agent compared to a phosphonate-based chelating agent in increasing the complexation capacity of the detergent composition. 
     The applications being thus described, it will be obvious that the same may be varied in many ways.
