Description: Emulsion Comprising a Ternary Surfactant Blend of Cationic, Anionic, and Bridging Surfactants, Oil and Water, and Methods of Preparing Same Field of the Invention The present invention relates to emulsions comprising an emulsification system comprising a mixture of at least one cationic surfactant, at least one anionic surfactant, at least one "bridging surfactant", an oil and water, along with methods for preparing such emulsions. More specifically, the invention relates to stable, synergistic emulsions of various oils, water, cationic, anionic, and bridging surfactants that are useful in preparing a variety of finished personal care, laundry, and cleaning products. The emulsification system of the instant invention, even when utilized in low levels, is capable allowing for the emulsification of very high levels of oils in water, whereby such emulsions are storage stable over extended periods of time at various temperatures. Additionally, concentrated emulsions of the invention are readily dilutable to very low concentrations, and yet, are also extremely stable phase systems. The instant invention further provides sunscreen emulsions, solid particulate matter suspensions and methods of producing the same. The emulsions of the instant invention are preferably oil-in-water emulsions, but may also be in the form of water-in- oil emulsions. Background of the Invention Water-in-oil and oil-in-water emulsions have been employed in a wide variety of applications. Among these are polishes and waxes for hard surfaces of, for example, automobiles, shoes, and furniture. Emulsions are also used as antiperspirants, sunscreens, skin creams and lotions, and hair treatment compositions such as hair conditioners. Incorporation of increased amounts of oil, and especially silicone oil, leads to difficulty in preparing stable formulations. It is particularly difficult to formulate stable emulsions having in excess of 50% by weight silicone oil. Thus, formulations of systems with oils such as silicones requires the use of an emulsification system capable of providing the requisite emulsion stability. U.S. Patent No. 5,188,823 discloses water-in-oil antiperspirant formulations comprising silicone oils, copolyols, phthalamic acids and/or ammonium phthalamates, and aluminum and zirconium antiperspirant salts. Water-in-oil formulations containing at most about 33% cyclomethiones are disclosed having viscosities ranging from about 2,700 to 14,000 cps. The pH of these water-in-oil formulations is from about 3.5 to 4.5. U.S. Patent No. 5,015,415 teaches conditioning shampoos comprising phthalamic acids and/or ammonium phthalamates and silicone oils. Shampoo formulations are disclosed with no more than 0.50% silicone oil. These formulations are taught to be stable at pH values between 3 and 9. Canadian Patent Application 2,056,859 discloses hair treatment compositions comprising a water-in-oil emulsion, wherein the water phase constitutes 40-95% by weight of the composition and the oil phase 5-60% by weight of the composition, wherein the oil phase comprises a silicone material having a viscosity of 10 4 to 10 9 mPas at 25°C. Surfactant mixtures related or used in combination with emulsions are somewhat known. U.S. Pat. No. 5,441 ,541 (to Colgate-Palmolive) describes the use of anionic and cationic complexes to remove oily soils from fabrics. U.S. Pat.

Mixed surfactant systems have also been disclosed in "Mixed Surfactant Systems", ACS Symposium Series 501 , P.M. Holland and D.N. Rubingh (June 17-19, 1991 ). Additionally, there have been many studies and symposia on mixed surfactant systems. See, for example, Scamehorn, J. F., ed., "Phenomena in Mixed Surfactant Systems", ACS Symposium Series 311 , Washington, D.C. (1986). The effects of alkyl groups and oxyethylene groups in nonionic surfactants on the surface tension of anionic-nonionic systems have been described. See Abe et al., J. Colloid Interface Sci., 107, p. 503 (1985); Ogino et al., J. Colloid Interface Sci., 107, p. 509 (1985); and Rosen et al., J. Colloid Interface Sci., 95, 443 (1983). Interaction between betaines and cationic surfactants has also been studied. See Zhu et al., J. Colloid Interface Sci., 108, 423 (1985). Mixed surfactant systems have shown synergistic improvements in surfactant properties compared to the properties of their individual surfactant components. Synergism increases with the degree of charge difference. Thus, the greatest synergistic surfactant property improvements are realized when mixing anionic and cationic surfactants. See Rosen et al. in "Phenomena in Mixed Surfactant Systems" (Scamehorn, J. F., ed.), ACS Symposium Series 311 , Washington, D.C. (1986), pp. 144-162; Zhao et al. in "Phenomena in Mixed Surfactant Systems" (Scamehorn, J. F., ed.) ACS Symposium Series 311 , Washington, D.C. (1986) pp. 184-198. In detergent applications, although in principle any surfactant is suitable, in practice only anionic and nonionic surfactants typically are used. Cationic surfactants, especially quaternary ammonium salts, can decrease detergency and enhance soil redeposition when used in heavy-duty liquid detergents. Consequently, there is a general notion that anionic and cationic surfactants cannot be used in the same formula without loss of efficacy. Similar worries regarding potential loss of efficacy exist when contemplating use of cationic surfactants in hair and skin conditioning applications. Thus, anionic-cationic surfactant mixtures have been used only sparingly in the production of consumer cleaning products and personal care products. Studies on anionic-cationic systems are recent and few compared to studies on other mixed surfactant systems. However, strong synergism has been exhibited by these systems. Surface activity properties, particularly the critical micelle concentration (cmc), surface tension, and microemulsion behavior (Bourrel et al., Tenside Detergents, 21 , 311 (1984)), were the most studied properties. For example, the surface activities of mixed aqueous solutions of sodium dihexylsulfosuccinate with dioctyl(hydroxyethyl)methylammonium chloride and sodium dihexylsulfosuccinate with octyl(hydroxyethyl)dimethylammonium chloride were much higher than those of the single surfactants. See Zao, G., Huoxue Xuebo, 43, 705 (1985) (Ch. Chem. Abstracts 103:184033n). The strong synergistic effect on surface pressure for mixed solutions of cationic and anionic surfactants has been studied quantitatively. When dilute solutions of sodium dodecylsulfate and dodecyltrimethylammonium bromide were mixed, tile surface pressure increased by more than 40 mN/m. Also, the cmc and the minimum surface tension were lower for the mixture than for either the anionic or cationic surfactants alone (Lucassen-Reynders et al., J. Colloid Interface Sci., 81 , p. 150 (1981 )). However, mixed anionic-cationic mixtures also have shown antagonistic effects relative to the properties of the individual surfactant components. See Chobanu et al., Izv. Akad. Nauk. Mold. SSR, Ser. Biol. Khim. Nauk., 5, p. 66 (1982). Unlike other mixed surfactant systems, most anionic-cationic surfactant mixtures studied are insoluble or only slightly soluble in water. Hence, practical use of anionic-cationic surfactant mixtures has been very limited in areas where a relatively high concentration of surfactants is needed (see U.S. Pat. No. 5,472,455, to Mehreteab, issued Dec. 5, 1995). Also see generally, Khan, A.; Marques, E.; Spec. Surfactants 1997, 37-80, edited by Robb, I. D. Blackie. Because the probability of synergism between surfactants increases with the strength of interaction, the greatest probability of synergism with anionic surfactants exists in anionic-cationic or anionic-zwiterionic mixtures. See generally, Surfactant and Interfacial Phenomena; Rosen, M.; John Wiley & Sons, Inc. 1989 p. 402. Surfactant performance is gauged by the so-called β value, which is a negative number indicating how much less a system's actual surface tension is compared to its calculated surface tension. Surfactant mixtures exhibiting larger deviations between calculated and actual surface tension perform better; thus, surfactant performance increases with progressively more negative β values. However, with respect to anionic-cationic mixtures, the variations in surfactant type and size that produce progressively more negative β values unfortunately are accompanied by decreasing solubility. Hence anionic-cationic synergism is limited by the formation of an insoluble salt, which typically occurs when the combined number of carbon atoms in the chains of both surfactants totals more than about twenty. See generally, Lomax, E; Specialty Chemicals 1993, v 13 n 4 p 223-227). Overall, there is a strong need for emulsification systems which will allow for the emulsification of large amounts of oil, produce emulsions which are stable phases over prolonged periods of time, are stable at a variety of concentrations and at a variety of temperatures, and are dilutable and stable when diluted. Additionally, there is a strong need for sunscreen emulsions and particulate mater suspensions with similar attributes. Further such emulsions and/or suspensions should be readily formulatable in to a variety of end use products, easy to handle, and safe to handle. Summary of the Invention The emulsions of the present invention are useful for preparing a variety of personal care, laundry, and cleaning products, including for example, creams, lotions, suncreens, hand soaps, laundry bars, personal cleansing bars, multi-purpose cleaners, multi-functional shampoos, body washes, liquid dish detergents, laundry detergents, automatic dishwasher detergents and textile treatment compositions. The emulsions of the present invention also may be employed in agricultural and pesticide applications. Additionally, the emulsions may be self-preserving (as explained in more detail below) and/or may be utilized in a variety of antimicrobial formulations (e.g., antimicrobial hard surface cleaners, hand soaps, shampoos, and dish detergents), soft-terg delivery systems and pre-spotter compositions. Surprisingly, it has been discovered that complexes of anionic and cationic surfactants can be utilized in combination with a bridging surfactant to produce an emulsification system which allows for the emulsification of various oils and/or allows for the suspension of various particulate matter. The inventive emulsions and suspensions detailed herein are generally stable over a wide concentration range and at various temperatures over extend periods of time and are also surprisingly stable when diluted to low levels of oil and/or partilucate matter. One aspect of the present invention relates to an emulsification system comprising at least one cationic surfactant, at least one anionic surfactant, and at least one "bridging surfactant". This system is useful in emulsifying oils and/or suspending solid particulate matter. Typically, the ternary surfactant blend comprises (a) at least one cationic surfactant, (b) at least one anionic surfactant, and (c) at least one bridging surfactant, in a molar ratio of (a):(b):(c) generally of about 1 :1 :1.

Thus, the invention provides an ternary surfactant emulsion system comprising a synergistic mixture of anionic, cationic and bridging surfactants. This invention further relates to personal care, laundry, and cleaning products, including for example, creams, lotions, suncreens, hand soaps, laundry bars, personal cleansing bars, multi-purpose cleaners, multi-functional shampoos, body washes, liquid dish detergents, laundry detergents, automatic dishwasher detergents and textile treatment compositions which contain the inventive emulsions.

The surfactant compositions of the present invention optionally contain from about 0.001 percent to about 20 percent of optional ingredients such as those described in detail below and those generally selected from the group comprising anti- dandruff agents, fragrance oils, perfumes, coloring agents, dyes, sequestering agents, preservatives, pearlescent/ suspending agents, thickener, viscosity modifiers, pH adjusting agents, gelling agents, opacifying agents, foam stabilizing auxiliary surfactants, silicone oils, non-volatile/nonionic silicone conditioning agents, vitamins, protein, sunscreen agents and mixtures thereof. These and other aspects and advantages, as well as the scope, nature, and utilization of the claimed invention will become apparent to those skilled in the art from the following detailed description and claims. Detailed Description Surprisingly, it has been found that the combination of a cationic surfactant, an anionic surfactant, and a bridging surfactant form a ternary blend which is particularly useful as an emulsification system for oil and/or a suspension system for solid particulate matter. In ternary surfactant blends of the invention, the use of additional hydrophilic groups (such as ethylene oxide groups or additional charge that remains un-neutralized during complexation) on the anionic or cationic surfactant is not necessary to produce an efficacious emulsifier system. The present invention provides ternary surfactant emulsifier systems comprising cationic, anionic and bridging surfactants wherein anionic/cationic complexes are formed. While not intending to be limited by a particular theory, it is believed that the quaternary ammonium agent (a cationic surfactant) and anionic surfactants typically form ion pair complexes in aqueous solutions. Ternary surfactant emulsification systems of the invention are generally flowable at concentrations as high as about 80 percent by weight. The inventive emulsions prepared using the emulsification system are stable phase emulsions which are readily dilutable. Highly diluted emulsions may be clear to opaque/hazy in appearance. The interfacial surface tension, detergency and emulsification behavior of an anionic-cationic complex is very different compared to either of the individual anionic and cationic surfactant components. In particular, an anionic-cationic complex exhibits significantly lower interfacial surface tension and significantly higher foaming than either an anionic or cationic surfactant alone. In similar fashion, the interfacial tension between certain oils and an aqueous solution of a ternary surfactant blend of the invention was found to be lower than the interfacial tension between the same oils and an aqueous solution of the individual anionic, cationic, or bridging surfactants, or combinations of two of these surfactants. More specifically in one embodiment, the present invention provides for a stable emulsion comprising: (a) from about 0.3 % to about 15 % by weight, based on the total weight of the emulsion, of an emulsification system comprising: i) from about 0.1 % to about 8 % by weight, based on the total weight of the emulsion, of a cationic surfactant ; ii) a from about 0.1 % to about 8 % by weight, based on the total weight of the emulsion, of an anionic surfactant; iii) from about 0.1 % to about 8 % by weight, based on the total weight of the emulsion, of a bridging surfactant; (b) from about 3 % to about 70 % by weight, based on the total weight of the emulsion, of an oil; and (c) from about 15 % to about 97 % by weight, based on the total weight of the emulsion, of water. Somewhat more preferably in this embodiment, the emulsion comprise from about 0.3 % to about 10 % by weight, based on the total weight of the emulsion, of the emulsification system; from about 3 % to about 70 % by weight, based on the total weight of the emulsion, of an oil; and from about 6 % to about 95 % by weight, based on the total weight of the emulsion, of water. Also some what more preferably, the cationic surfactant is a quaternary ammonium compound of the formula: + R 2 -N-R 3 X R 4 where Rπ, R 2 , and R 3 are independently ethyl, methyl or benzyl; R 4 is an alkyl group having an average of from about 8 to about 18 carbon atoms; and X is halogen, sulfate, methosulfate, ethosulfate, tosylate, acetate, phosphate, nitrate, sulfonate, or carboxylate; or is a compound of the general formula (I) R 2 E 2 R 1 E 1 + R 3 E 3 [ X- ] R 4 wherein X " is an anion, R.,, R 2 , R 3 can be the same or different and are independently straight or branched chain alkyl groups of from 2 to about 6 carbon atoms; R4 is a saturated or unsaturated, straight or branched chain aliphatic group having from about 1 to about 6 carbon atoms optionally substituted with hydroxy, epoxy or halogen and E.,, E 2 and E 3 can be the same or different at each occurrence and are selected from the group consisting of --H, --OH and aliphatic ester groups of the following formula (II): wherein R 5 is a saturated or unsaturated, straight or branched chain aliphatic group of from about 11 to about 24 carbon atoms, optionally substituted with hydroxy, epoxy or halogen, provided that at least one of E.,, E 2 or E 3 is a group of formula (II); or a mixture thereof. Further in accordance with this embodiment, the anionic surfactant is preferably an alkyl sulfate having an average of from about 8 to about 16 carbon atoms, an alkyl sulfonate having an average of from about 8 to about 18 carbon atoms, an alkyl ether sulfate having an average of from about 8 to about 16 carbon atoms in the alkyl portion and from about 1 to about 30 moles of ethylene oxide, an α- olefin sulfonate having an average of from about 12 to about 18 carbon atoms, an α- sulfonated C C 6 alkyl ester of a fatty acid having an average of from about 11 to about 16 carbon atoms, a sulfosuccinate having an average of from about 10 to about 16 carbon atoms, a sarcosinate having an average of from about 10 to about 16 carbon atoms, a sulfoacetate having an average of from about 12 to about 20 carbon atoms, or a phthalamate, or a mixture thereof. In a highly preferred embodiment the anionic surfactant is an alkyl sulfate having an average of from about 10 to about 12 carbon atoms, an α-sulfonated O,-C 6 alkyl ester of a fatty acid having an average of from about 1 1 to about 16 carbon atoms, an alkyl sulfonate having an average of about 8 carbon atoms, or a stearyl phthalamate, an alkyl ether sulfate having an average of from about 8 to about 16 carbon atoms in the alkyl portion and from about 1 to about 30 moles of ethylene oxide, or a mixture thereof. Also somewhat more preferably, the bridging surfactant selected from the group consisting of amine oxides, ethoxamides, and betaines, or a mixture thereof. The oil is preferably a silicon oil, mineral oil, a cosmetic ester or petrolatum, or a mixture thereof. Preferably, the molar ratio of cationic surfactant to anionic surfactant to bridging surfactant is about 1 :1 :1. Additionally, the emulsion comprises a stable phase at 25°C for 30 days, and/or a stable phase at 43°C for 30 days and/or a stable phase at 50°C for 30 days. Further, the emulsion may be preferably in the form of an oil-in-water emulsioin or may be in the form of a water-in-oil emulsion. The viscosity of the emulsions and/or diluted emulsions can very from thin, i.e., 100 cps, to thick cream like consistency, i.e., 80,000 cps. A critical and surprising discovery is that the invention further provides for a diluted emulsion comprising an emulsion from the above or below embodiments, wherein the emulsion has been diluted with water, whereby the total concentration of oil is from about 5 % to about 15 % by weight, based on the total weight of the diluted emulsion and the diluted emulsion is stable and comprises a stable phase at 50°C for 30 days. Typically, as known to those skilled in the are, emulsions typically break down upon dilution into multiple phases, i.e., they are not storage stable. Generally, the inventive emulsions can be diluted with water to give stable phase diluted emulsions which are stable at a variety of temperatures over extended periods of time.

When prepared in this manner, the alpha sulfonated alkyl esters normally contain a minor amount, typically not exceeding 33% by weight, of alpha sulfonated fatty acid, i.e., disalt, which results from hydrolysis of the ester. Generally, larger amounts of the disalt are obtained by hydrolyzing a known amount of the monosalt; hydrolysis may be accomplished in situ during the preparation of the composition. Accordingly, the alpha sulfonated alkyl ester and alpha sulfonated fatty acid may be provided to the composition (or utilized in the inventive process) as a blend of components which naturally result from the sulfonation of an alkyl ester of a fatty acid, or as individual components. Furthermore, it is known to one skilled in the art that minor impurities such as sodium sulfate, unsulfonated methyl esters (ME), and unsulfonated fatty acids (FA) may also be present in the mixtures according to the invention. The alpha sulfonated alkyl esters, i.e., alkyl ester sulfonate surfactants, include linear esters of C e -C 22 carboxylic acid (i.e., fatty acids) which are sulfonated with gaseous S0 3 according to the "The Journal of American Oil Chemists Society," 52 (1975), pp. 323-329.

Additional optional pearlescent/suspending agents suitable for use in the present invention are alkyl (C18-C22) dimethyl amine oxides, such as stearyl dimethyl amine oxide. If the compositions contain an amine oxide or a long chain acyl derivative as a surfactant the pearlescent/suspending function could also be provided by such surfactant and additional pearlescent/suspending agents may not be needed. Further optional pearlescent/suspending agents that can be used are long chain acyl derivatives, including, for example, N,N-dihydroxycarbyl amido benzoic acid and soluble thereof (e.g., Na and K salts), particularly N,N-di(hydrogenated) C-j β.

Another type of pearlescent/suspending agent which can be used in the present invention is xanthan gum. Xanthan gum is well ' known to those skilled in the art. For example, hair care compositions utilizing xanthan gum as a pearlescent/suspending agent for the silicone hair conditioning component are described in U.S. Pat. No. 4,788,066, Bolich and Williams, issued Nov. 29, 1988, the disclosure of which is incorporated herein by reference in its entirety. See also, Whistler, Roy L. Editor Industrial Gums - Polysaccharides and Their Derivatives, New York: Academic Press, 1973. Xanthan gum is commercially available from Kelco, a division of Merck & Co., Inc. as Keltrol. Combinations of long chain acyl derivatives and xanthan gum are disclosed as pearlescent/suspending agents for silicone hair conditioners in U.S. Pat. No. 4,704,272, Oh et al., issued Nov. 3, 1987, both of which are incorporated herein by referenced in their entirety, and may also be used in the present compositions. Gel formulations have high levels of pearlescent/suspending agents relative to pourable, liquid formulations which used as the primary means of imparting gel-like viscosity. Optional gelling agents suitable for use in the present invention include, for example, hydroxy ethylcellulose. Other optional conditioning agents include sucrogylericide materials, particularly those disclosed in U.S. Pat. No. 5,705,147, issued Jan. 6, 1998 to Stepan Company, incorporated herein in its entirety.

Examples of other optional ingredients useful in formulating with compositions of the present invention include, for example, silicone polymers; preservatives, such as para-hydroxy benzoate esters; humectants, such as butane-1 ,3-diol, glycerol, sorbitol, polyethylene glycol; stabilizers, such as sodium chloride or ammonium chloride; buffer systems, such as lactic acid together with a base such as sodium hydroxide; thickeners; activity enhancers; colorants; whiteners; fragrances; and bactericides, and mixtures thereof. The compositions of the present invention may also be formulated into finished detergent formulations, in combination with optional detergent builder materials. Nearly any detergent builders known in the art can be formulated with the present blends. Examples of useful detergent builders are described in U.S. Pat. Nos. 4,321 ,165, (to Smith et al, issued Mar. 23, 1982) and 5,565,145 (to Watson et al., issued Oct. 15, 1996), both incorporated herein by reference. Detergent builders can optionally be included in the compositions herein to assist in controlling mineral hardness. Inorganic as well as organic builders can be used. Builders are typically used in fabric laundering compositions to assist in the removal of particulate soils. The level of builder can vary widely depending upon the end use of the composition and its desired physical form. When present in a final formulation, the compositions will typically comprise at least about 1 % builder. Liquid formulations typically comprise from about 5% to about 50%, more typically about 5% to about 30%, by weight, of detergent builder. Granular finished formulations typically comprise from about 10% to about 80%, more typically from about 15% to about 50% by weight, of the detergent builder. Lower or higher levels of builder, however, also can be acceptable. Enzymes and enzyme stabilizers can be formulated with compositions of the instant invention for a wide variety of fabric laundering purposes, including removal of protein-based, carbohydrate-based, or triglyceride-based stains, for example, and for fabric restoration. Examples of useful enzymes and enzyme stabilizers are described in U.S. Pat. No. 5,565,145 (to Watson et al., issued Oct. 15, 1996), incorporated herein by reference. Useful enzymes include, for example, proteases, amylases, lipases, and cellulases, as well as mixtures thereof. Other types of enzymes may also be included. They may be of any suitable origin, such as vegetable, animal, bacterial, fungal and yeast origin. However, a particular enzyme choice is governed by several factors such as pH-activity and/or stability optima, thermostability, stability versus active detergents, builders and so on. In this respect bacterial or fungal enzymes are preferred, such as bacterial amylases and proteases, and fungal cellulases. Suitable examples of proteases are the subtilisins which are obtained from particular strains of B. subtilis and B. Iicheniforms. Another suitable protease is obtained from a strain of Bacillus, having maximum activity throughout the pH range of 8-12, developed and sold by Novo Industries A/S under the registered trade name ESPERASE. The preparation of this enzyme and analogous enzymes is described in British Pat. Specification No. 1 ,243,784 of Novo. Proteolytic enzymes suitable for removing protein-based stains that are commercially available include those sold under the tradenames ALCALASE and SAVINASE by Novo Industries A/S (Denmark) and MAXATASE by International Bio-Synthetics, Inc. (The Netherlands). Other proteases include Protease A (see European Patent Application 130,756, published Jan. 9, 1985) and Protease B (see European Patent Application Ser. No. 87303761.8, filed Apr. 28, 1987, and European Patent Application 130,756, Bott et al, published Jan. 9, 1985). Amylases include, for example, amylases described in British Patent Specification No. 1 ,296,839 (Novo), RAPIDASE, International Bio-Synthetics, Inc. and TERMAMYL, Novo Industries. Cellulases suitable for use with compositions of the present invention include both bacterial or fungal cellulase. Preferably, they will have a pH optimum of between 5 and 9.5. Suitable cellulases are disclosed in U.S. Pat. 4,435,307, Barbesgoard et al, issued Mar. 6, 1984, which discloses fungal cellulase produced from Humicola insolens and Humicola strain DSM1800 or a cellulase 212-producing fungus belonging to the genus Aeromonas, and cellulase extracted from the hepatopancreas of a marine mollusk (Dolabella Auricula Solander). Suitable cellulases are also disclosed in GB-A-2.075.028; GB-A-2.095.275 and DE-OS.247.832CAREZYME (Novo) is especially useful. Suitable lipase enzymes include those produced by microorganisms of the Pseudomonas group, such as Pseudomonas stutzeri ATCC 19.154, as disclosed in British Patent. 1 ,372,034. See also lipases in Japanese Patent Application 53,20487, laid open to public inspection on Feb. 24, 1978. This lipase is available from Amano Pharmaceutical Co. Ltd., Nagoya, Japan, under the trade name Lipase P Amano, hereinafter referred to as Amano-P. Other commercial lipases include Amano-CES, lipases ex Chromobacter viscosum, e.g. Chromobacter viscosum var. lipolyticum NRRLB 3673, commercially available from Toyo Jozo Co., Tagata, Japan; and further Chromobacter viscosum lipases from U.S. Biochemical Corp., U.S.A. and Diosynth Co., The Netherlands, and lipases ex Pseudomonas gladioli. The LIPOLASE enzyme derived from Humicola lanuginosa and commercially available from Novo (see also EPO 341 ,947) is a preferred lipase for use herein. A wide range of enzyme materials and means for their incorporation into synthetic detergent compositions are also disclosed in U.S. Pat. No. 3,553,139, issued Jan. 5, 1971 to McCarty et al. Enzymes are further disclosed in U.S. Pat. No. 4,101 ,457, Place et al, issued Jul. 18, 1978, and in U.S. Pat. No. 4,507,219, Hughes, issued Mar. 26, 1985, both. Enzyme materials useful for liquid detergent formulations, and their incorporation into such formulations, are disclosed in U.S. Pat. No. 4,261 ,868, Hora et al, issued Apr. 14, 1981. Enzymes for use in detergents can be stabilized by various techniques. Enzyme stabilization techniques are disclosed and exemplified in U.S. Pat. No. 3,600,319, issued Aug. 17, 1971 to Gedge, et al, and European Patent Application Publication No. 0 199 405, Application No. 86200586.5, published Oct. 29, 1986, Venegas. Enzyme stabilization systems are also described, for example, in U.S. Pat. No. 3,519,570. The optional enzymes useful herein may be stabilized by the presence of water- soluble sources of calcium and/or magnesium ions in the finished compositions which provide such ions to the enzymes. Calcium ions are generally somewhat more effective than magnesium ions and are preferred herein if only one type of cation is being used. Additional stability can be provided by the presence of various other disclosed stabilizers, especially borate species. See Severson, U.S. Pat. No. 4,537,706. Typical detergents, especially liquids, will comprise from about 1 to about 30, preferably from about 2 to about 20, more preferably from about 5 to about 15, and most preferably from about 8 to about 12, millimoles of calcium ion per liter of finished composition. This concentration can vary somewhat, depending on the amount of enzyme present and its response to the calcium or magnesium ions. The level of calcium or magnesium ions should be selected so that there is always some minimum level available for the enzyme, after allowing for complexation with builders, fatty acids, etc., in the final composition. Any water-soluble calcium or magnesium salt can be used as the source of calcium or magnesium ions, including, but not limited to, calcium chloride, calcium sulfate, calcium malate, calcium maleate, calcium hydroxide, calcium formate, and calcium acetate, and the corresponding magnesium salts. A small amount of calcium ion, generally from about 0.05 to about 0.4 millimoles per liter, is often also present in the final composition due to calcium in the enzyme slurry and formula water. In solid detergent compositions the final formulation may include a sufficient quantity of a water-soluble calcium ion source to provide such amounts in the laundry liquor. In the alternative, natural water hardness may suffice. Generally, the aforementioned levels of calcium and/or magnesium ions are sufficient to provide enzyme stability to a finished formulation. More calcium and/or magnesium ions can be added to the compositions to provide an additional measure of grease removal performance. Accordingly, final formulations prepared from the blends disclosed herein typically will comprise from about 0.05% to about 2% by weight of a water-soluble source of calcium or magnesium ions, or both. The amount of water-soluble ion can vary with the amount and type of enzyme employed in the final composition. Final compositions detailed herein, when utilized in a finished formulation, may also optionally contain various additional stabilizers, especially borate-type stabilizers. Boric acid is preferred, although other compounds such as boric oxide, borax and other borates (e.g., sodium ortho-, meta- and pyroborate, and sodium pentaborate) are suitable. Substituted boric acids (e.g., phenylboronic acid, butane boronic acid, and p-bromo phenylboronic acid) can also be used in place of boric acid. Bleaching agents, bleach activators, chelating agents, anti-redeposition agents, polymeric dispersing agents, optical brighteners, suds suppressors, dye transfer inhibition agents, optical brighteners, and soil release agents can be formulated with blends of the instant invention. Examples of such materials are generally described in U.S. Pat. No. 5,565,145 (to Watson et al., issued Oct. 15, 1996), incorporated herein by reference. Various other detergent additives or adjuvants may be present in the detergent product to give it additional desired properties, either of functional or aesthetic nature. Thus, there may be included in the formulation minor amounts of soil suspending or anti-redeposition agents, e.g. polyvinyl alcohol, fatty amides, sodium carboxymethyl cellulose, hydroxy-propyl methyl cellulose; optical brighteners, e.g. cotton, amine and polyester brighteners, for example, stilbene, triazole and benzidine sulfone compositions, especially, sulfonated substituted triazinyl stilbene, sulfonated naphthotriazole stilbene, benzidine sulfone, etc., most preferred are stilbene and triazole combinations. Bluing agents such as ultramarine blue; enzymes, preferably proteolytic enzymes, such as subtilisin, bromelin, papain, trypsin and pepsin, as well as amylase type enzymes; bactericides, e.g. tetrachlorosalicylanilide, hexachlorophene; fungicides; dyes; pigments (water dispersible); preservatives; ultraviolet absorbers; anti-yellowing agents, such as sodium carboxymethyl cellulose, complex of C-|2 to C22 alkyl alcohol with C12 to C-| 8 alkylsulfate; pH modifiers and pH buffers; color safe bleaches, perfume, and anti-foam agents or suds suppressors, e.g. silicon compounds, can also be used. In the case of final formulations, other optional ingredients include neutralizing agents, buffering agents, phase regulants, hydrotropes, polyacids, suds regulants, opacifiers, antioxidants, preservatives, bactericides, dyes, perfumes, and brighteners described in the U.S. Pat. No. 4,285,841 , Barrat et al, issued Aug. 25, 1981 , incorporated herein by reference. Other ingredients useful in final detergent compositions can be formulated with blends of the instant invention, including carders, processing aids, pigments, solvents for liquid formulations, solid fillers for bar compositions, sodium sulfate, sodium chloride, protein hydrolysates, cholesterol derivatives, UV absorbers, chelating agents, etc. If high sudsing is desired, suds boosters such as the C-J Q-C16 alkanolamides can be incorporated into the final compositions, typically at 1 %— 10% levels. The C10-C14 monoethanol and diethanol amides illustrate a typical class of such suds boosters. If desired, soluble magnesium salts such as MgCl2, MgS04, and the like, can be added at levels of, typically, 0.1 %- 2%, to provide additional suds and to enhance grease removal performance to a final formulation. Additionally, the compositions may optionally contain non-conventional surfactants, such as fluorosurfactants, gemini surfactants and polymeric cationic and polymeric anionic surfactants. The emulsification systems of the invention also comprise polysiloxane polyalkyl polyether copolymers, le ^ , silicone glycol surfactants which are also known as copolyols. The amount of silicone glycol surfactant is preferably about 0.5 to 15% by weight. A more preferable amount of the silicone glycol surfactant is about 0.5-5% of the composition. Suitable silicone surfactants are for example high molecular weight polymers of dimethyl polysiloxane with polyoxyethylene and/or polyoxypropylene side chains, having a molecular weight of from 10,000 to 50,000 and having the structure: CH, CH 3 CH 3 H 3 C- S — 0- Si— 0 • Si— CH, I I ChU R" CH 3 wherein the groups R" are each chosen from -H, C,_ 18 alkyl and R" is - [CH 2 CH 2 0] a [CH 2 (CH 2 )CHO] b H, in which a has a value of from 9 to 1 15, b has a value of from 0 to 50, x has a value of from 133 to 673, y has a value of from 25 to 0.25. Preferably, the polymer is an alkoxylated polydimethyi polymer in which: a has a value of from 10 to 114, b has a value of from 0 to 49, x has a value of from 388 to 402, y has a value of from 15 to 0.75, Mthe group R" having a molecular weight of from 1000 to 5000. A more preferred alkoxylated dimethyl polysiloxane polymer is one in which: a has the value 14, b has the value 13, x has the value 249, y has the value 1.25. A particularly preferred copolyol is cetyl dimethicone copolyol, available from T.H. Goldschmidt as Abil® EM-90. Blends of the present invention are prepared from readily available, economical raw materials, and generally their preparation does not require any special handling or equipment. The blends may be prepared in a batch mode or a continuous mode. Suitable preservatives are selected from the group comprising benzyl alcohol, methyl paraben, propyl paraben and imidazolidinyl urea. Suitable thickeners and viscosity modifiers are selected from the group comprising diethanolamides of long chain fatty acids (e.g., PEG-3 lauramide), block polymers of ethylene oxide and propylene oxide such as Pluronic® F88 offered by BASF, Wyandotte, sodium chloride, sodium sulfate, ammonium xylene sulfonate, ethyl alcohol and polyhydridic alcohols such as, for example, propylene glycol and polyvinyl alcohol. Suitable gelling agents include, for example, hydroxyethyl cellulose. Suitable pH adjusting agents are selected from the group comprising citric acid, succinic acid, phosphoric acid, sodium hydroxide, sodiumcarbonate, etc. Suitable sequestering agents include, for example, disodium ethylenediamine tetraacetate. The compositions of the present invention typically contain water as the solvent; however, other solvents may optionally be employed, either alone or in combination with water. Low molecular weight primary or secondary alcohols, exemplified by methanol, ethanol, propanoi, and isopropanol, are suitable optional solvents. Monohydric alcohols are preferred optional solvents, but polyols such as those containing from 2 to about 6 carbon atoms and from 2 to about 6 hydroxy groups (e.g., 1 ,3-propanediol, ethylene glycol, glycerine, and 1 ,2-propanediol) can also be used. The compositions may contain from about 5 to about 90 percent, typically from about 10 to about 50 percent by weight of water and/or optional solvent. While pH is of secondary significance herein, the compositions of the present invention typically are prepared having a pH of between about 2 and about 10, preferably between about 5 and about 8. Techniques for controlling pH at recommended usage levels include the use of buffers, alkalis, acids, etc., and are well known to those skilled in the art. Suitable materials for adjusting the pH of these compositions include triethanolamine, diethanolamine, sodium carbonate, sodium bicarbonate, and the like. The ternary surfactant emulsification system of this invention, in addition to emulsifying oils and suspending particulate mater, may also by itself be formulated into commercially useful products. Additionally, the ternary surfactant blends may be processed into a variety of forms such as, for example, liquids, solutions, solids, powders, flakes, semi-solids, gels, "ringing" gels, G-phase liquids/pastes, hexagonal liquid crystal phases, or thick non-flowable pastes. The ternary surfactant blends may be spray dried, flaked, or extruded. Although not critical to the present invention, the blends may be prepared "neat" or in a conventional solvent such as water, low molecular weight alcohol or hydrocarbon, or a mixture thereof, to produce a solution of the ternary surfactant blend. The present invention encompasses ternary surfactant systems in dry form and as aqueous solutions. Ternary surfactant blends in concentrations up to 100 percent by weight may be isolated by drying a solution of the blend. Conversely, ternary surfactant blend solutions may be prepared by dissolving a solid form of the blend in water, low molecular weight alcohol, low molecular weight glycol, or mixtures thereof. One skilled in the art will recognize that modifications may be made in the present invention without deviating from the spirit or scope of the invention. The invention is illustrated further by the following examples, which are not to be construed as limiting the invention or scope of the specific procedures or compositions described herein.

The invention is illustrated further by the following examples, which are not to be construed as limiting the invention or scope of the specific procedures or compositions described herein. In the following examples, all amounts are stated in percent by weight of active material unless indicated otherwise. Example 1 : Concentrated o/w emulsions Several concentrated o/w emulsions as shown in Table 1 were prepared using the following procedure. Premix with agitation, at about 25°C, the anionic surfactant, cationic surfactant, and bridging surfactant at equimolar ratios. Add the water to the surfactant mixture and mixing well with agitation. Add the oil phase, mix well with agitation at about 25°C for 30 minutes. As can be seen by the results reported in Table 1 , stable concentrated o/w emulsions are formed using different anionic- cationic-bridge systems and different oils (silicone, mineral oils). TABLE 1 * CAN system = cationic, anionic, nonionic or bridge surfactants Example 2 As shown in TABLE 2, a stable o/w emulsion is formed when an anionic, cationic, bridge surfactant system is used. Comparative unstable emulsions (emulsions 9-14) are obtained when individual surfactants or any of the two components surfactant system is used . It is critical to use the three components to form a stable emulsion. All emulsions shown in Table 2 below were prepared using the procedure described in Example 1 above. TABLE2 -4 "CAN system = cationic, anionic, nonionic or bridge surfactants Example 3 Various concentrated o/w emulsions were prepared using the same procedure as detailed in Example 1. As shown in Table 3 the stability of the concentrated emulsion was maintained over a wide pH range (2.5-10.5). TABLE 3 *CAN system = cationic, anionic, nonionic or bridge surfactants Example 4- Dilutable concentrated emulsions As shown in TABLE 4 the results indicate that dilutable emulsions prepared from the concentrated emulsions at room temperature are both obtainable and stable. The emulsions were prepared using the following procedure: Premix the anionic, cationic, bridge system at about 25°C with agitation and at equimolar ratios. Add the water to the surfactant mixture with agitation. Add the oil phase and mix well with agitation at 25°C for 30 minutes. After formation of the concentrated emulsion, the rheology modifier is dispersed in the required amount of water for the dilution, with agitation for about 5 minutes. Add the concentrated emulsion to this rheology/water phase along with concurrent addition of the triethanoamine until the desired pH is reached, with agitation at about 25°C for 30 minutes. The results below show that the concentrated emulsions (70%oil) are readily dilutable and stable upon dilution. TABLE 4 fe CAN system = cationic, anionic, nonionic or bridge surfactants Example 5 Several o/w emulsions with lower percentage of oil were prepared at about 25°C as shown in TABLE 5 using the following procedure: Premix the anionic, cationic, bridge surfactants at about 25°C at equimolar ratio (see the weight ratio in the table). Add the water to the surfactant mixture with agitation. Disperse the Carbopol Ultrez 10 in the aqueous layer with agitation. Add the oil phase to the Carbopol Ultrez 10/aqueous phase and mix well with agitation at 25°C for 5 minutes. Add the triethanolamine with agitation to the required pH (greater than 5). Continue the mixing for approximately 45 minutes at 25°C. The results indicate the successful formation of stable o/w emulsions using different anioncs, cationics or bridging systems. The results indicate that it is possible to emulsify a variety of different oils (silicone oil, mineral oil, cosmetic esters) at varying concentrations of such oils. TABLE 5 oe o oe *CAN system = cationic, anionic, nonionic or bridge surfactants Example 6 As shown in TABLE 6 a stable o/w emulsion is obtained without the premixing of the three anionic, cationic and nonionic/bridging surfactant components. The same procedure was used as per Example #5 above, the only difference was the anionic, cationic, bridge surfactants, along with the water, were individually added to the oil phase without the premixing. The results further indicate stable o/w emulsions using an anionic, cationic, bridge system as an emulsifier. Unstable emulsions are obtained when only the anionic and the cationic surfactants are used. The bridging surfactant serves to stabilize the emulsion. Table 6 Example 7 As shown in TABLE 7 o/w emulsions are formed using the following systems. The same procedure was used per Example 5 above, with the temperature being about 70°C. The ratio between the anionic:cationic:bridge was 1 :1 :1 mole ratio. Table 7 "CAN system = cationic, anionic, nonionic or bridge surfactants Example 8 As shown in TABLE 8 a stable o/w emulsion was obtained when the anionic, cationic, bridge system (1 :1 :1 mole ratio) was used as an emulsifier system for a sunscreen formulation. The result sindicate that the system can provide suspension capabilities for physical sunscreens.
