SHAMPOO PREMIX COMPOSITIONS

Abstract: Disclosed are shampoo premix compositions, shampoo compositions made therefrom, and methods of making such premixes and shampoos thereof. The shampoo premix comprises alkyl ethoxylated sulfate surfactant, a specific type of imidazolinium amphoteric surfactant, polyethylene glycol glyceryl fatty ester nonionic surfactant, a suspending agent that is solubilized and recrystallized in the premix composition at pH less than 7.0, and a sufficient amount of a pH adjustor, i.e., an acid, to adjust pH to less than 7.0 during recrystallisation of the composition. The shampoo premix hereof can be used as an end product, or used as a base from which to add additional shampoo ingredients to form a finished shampoo formulation. The shampoo premix hereof can provide mild, good lathering, pearlescent compositions. The premix compositions hereof are particularly useful for use in conditioning shampoo compositions containing silicone conditioning agents.

Description: SHAMPOO PREMIX COMPOSITIONS TECHNICAL FIELD The present invention is related to shampoo premix composi¬ tions as well as finished shampoo compositions comprising the premix and additional shampoo components and/or additional levels of components also included in the premix. The present invention also relates to a method of making said shampoo premix and shampoo compositions. BACKGROUND OF THE INVENTION Mild shampoo compositions which provide low irritation to the skin are highly desirable. Conventional shampoos contain high levels of harsh anionic surfactants. These materials can penetrate the skin and destroy its integrity. This results, at the very least, in rough skin, and can ultimately lead to red, irritated skin. Ideal shampoo compositions should provide sufficient lathering and cleaning benefits to cleanse the hair while at the same time causing little or no irritation to the skin. This is particularly essential for shampoo compositions used on babies, small children, or adults with dry or sensitive skin. Furthermore, children can have difficulty if they get shampoo in their eyes during the hair washing or rinsing process. Hence, mild shampoo compositions which also provide reduced eye sting are particularly desirable for use on children. Mild shampoo compositions, in general, are well known in the art having been taught in, for example, European Patent Application 0250181, published December 23, 1987; U.S. Patent 4,578,216, Fujii et al., issued March 25, 1986; U.S. Patent 4,726,915, Verdicchio, issued February 23, 1988; U.K. Patent Specification 1,508,929, published April 26, 1978; European Patent Application 0160269, published November 6, 1985; U.S. Patent 4,435,300, Guth et al., issued March 6, 1984; U.S. Patent 4,426,310, Vernunica, issued January 17, 1984; U.S. Patent 3,950,417, Verdicchio et al . , issued April 13, 1976; U.S. Patent 4,443,362, Guth et al . , issued April 17, 1984; U.S. Patent 4,654,207, Preston, issued March 31, 1987; U.S. Patent 4,851,154, Grollier et al . , issued July 25, 1989; U.S. Patent 4,292,212, Melby, issued September 29, 1981; and U.S. Patent 4,329,334, Su et al., issued May 11, 1982. These references teach the use of a wide variety of surfactant combinations to achieve mildness. These surfactants include mild anionic surfactants, such as ethoxylated alky! sulfates, a photeric surfactants, nonionic surfactants, and various combinations thereof. One well-known mild shampoo is Johnson's Baby Shampoo (John¬ son & Johnson). This product contains high levels of nonionic surfactant (PEG-80 Sorbitan Laurate), which is known to provide reduced eye sting. The formula is supplemented by some other mild surfactants to boost its cleaning performance (betaine, ethoxy¬ lated alkyl sulfate, an i idazoline-derived amphoteric, and an ethoxylated alkyl carboxylate) . The formulation of such mild shampoo compositions, however, generally is an exercise in efficacy and mildness trade-offs, with the resulting composition providing either good cleaning and lathering benefits, or mildness and low eye or skin irritation benefits. In fact, Johnson's Baby Shampoo, while being mild to the skin and eyes, is not a very good cleaner and its lathering profile is not particularly robust. Hence, it is an object of the present invention to provide a mild shampoo composition which provides good in-use character¬ istics such as lathering, both in terms of abundance of lather and lather stability, and cleaning, while at the same time providing skin mildness benefits, and preferably low eye sting benefits as well. It is also preferable that the shampoo have a pleasing aesthetic appearance which also referred to as pearlescence, in addition to providing the above characteristics. Also desirable in state of the art shampoo compositions are conditioning benefits inherent in the shampoo compositions. Such products are sometimes termed two-in-one shampoos, meaning the compositions include both cleaning and conditioning ingredients in the same product. Such compositions are difficult to formulate because the cleaning ingredients, in general, tend to be incompat¬ ible with the conditioning ingredients. One highly successful solution to this dilemma has been to use dispersed insoluble non-volatile silicone materials together with certain suspending agents for the silicones in shampoo compositions. Such technology is taught in U.S. Patent 4,704,272, Oh et al . , issued November 3, 1987; U.S. Patent 4,741,855, Grote et al., issued May 3, 1988; and U.S. Patent 4,788,006, Bolich et al., issued June 5, 1984. Another benefit of certain of the suspending agents referred to in these patents is their ability to improve the aesthetic appearance of shampoos by adding pearlescence. However, one problem with the use of silicone materials to deliver hair conditioning from shampoo compositions is that such materials, in general, tend to suppress lathering of the composition. If silicones are used with robust high-lathering surfactants, such as most anionic surfactants, lathering may not be unduly affected. However, if such materials are used with milder, less robust lathering surfactants, lathering may well be suppressed to an unacceptable level from a consumer standpoint. Hence, it is a further object of the present invention to provide a mild shampoo composition which provides excellent lathering and cleaning benefits while at the same time providing hair conditioning benefits through the use of dispersed insoluble non-volatile silicone conditioning agents. Alkyl sulfate surfactants tend to be harsh to the skin and are therefore not conducive to formulating mild shampoos. Unfor¬ tunately, in the absence of such alkyl sulfates it is difficult to get the suspending agent into the shampoo in crystalline form. It is when the suspending agent is present in the shampoo in the form of a crystalline network that it is effective in suspending the silicone composition. The presence of volatile solvents, such as those typically present in perfumes, can under certain circumstances assist in the formulation of shampoos with effective crystalline suspending agent networks. However, that undesirably involves adding the perfume at a stage wherein the composition is subject to high temperatures, i.e., when the suspending agent is being solubilized prior to the subsequent step of cooling it to cause the suspending agent to recrystallize as an effective suspending agent network. Exposure of such volatile components to high temperatures can raise undesirable safety and aesthetic issues. Improved mild shampoos, i.e., shampoos that are mild and which have both good cleaning and robust lathering have been proposed in U.S. Serial No. 07/681,015* filed April 5, 1991, E. J. Inman, "Mild Shampoo Compositions", wherein particular combina¬ tions of imidazolinium-type amphoteric surfactants and amino- alkanoate and/or i inodialkanoate amphoteric surfactants are required. These compositions can contain suspending agents and dispersed insoluble silicone. Similar compositions are also described in U.S. Serial No. 07/681,016?* iled April 5, 1991, E. J. Inman, "Hair Conditioning Shampoo Compositions With Silicone Conditioning Agent". Whereas these compositions can provide excellent performance, it remains desirable to provide mild, good lathering, good cleaning shampoo compositions which can be pro¬ cessed into shampoos containing highly effective crystalline networks for suspension of silicone without requiring the presence of volatile solvents and/or iminodialkanoate and/or aminoalkanoate surfactants, in addition to the imidazolinium-type surfactants (e.g., cocoamphoglycinate) disclosed therein. These and other objects will become readily apparent from the detailed description which follows. Unless otherwise indicated, all percentages are calculated by weight of the total composition and all ratios are calculated on a weight basis. The compositions and processes herein can comprise, consist essentially of, or consist of any of the critical and optional elements and steps described in this application.

The invention, including preferred embodiments thereof, is described in more detail in the Detailed Description of the Invention, which follows. DETAILED DESCRIPTION OF THE INVENTION The essential as well as certain preferred and optimal components of the compositions of the present invention are described below. Alkyl ethoxylated sulfate surfactants are well known in the art. They typically have the formula R0(C2H40) X S03M, wherein R is alkyl or alkenyl of from about 8 to about 24 carbon atoms, x is 1 to 12, and M is a water-soluble cation such as ammonium, an alkali metal (e.g., sodium, potassium) alkali earth metal, and tri- ethanola ine. Useful alkyl ethoxylated sulfates are condensation products of ethylene oxide and monohydric alcohols having from about 8 to about 24 carbon atoms. Preferably, R has from about 10 to about 18 carbon atoms. The alcohols can be derived from fats, e.g., coconut oil or tallow, or can be synthetic. Lauryl alcohol and straight chain alcohols derived from coconut oil are preferred herein. Such alcohols are reacted with from about 1 to about 12, preferably from about 2 to about 6, and especially about 3, molar proportions of ethylene oxide and the resulting mixture of molecu¬ lar species having, for example, an average moles of ethylene oxide per mole of alcohol within the above limits, is sulfated and neutralized. Specific examples of alkyl ethoxylated sulfates which may be used in the present invention are sodium and/or ammonium salts of coconut alkyl triethylene glycol ethoxylated sulfate, tallow alkyl triethylene glycol ethoxylated sulfate, and tallow alkyl hexaoxy- ethylene sulfate. Typically the alkyl ether sulfates will com¬ prise a mixture of individual compounds, said mixture having an average alkyl chain length of from about 12 to about 16 carbon atoms and an average degree of ethoxylation of from about 2 to about 6 moles of ethylene oxide, especially about 3. Especially preferred are narrow range alkyl ethoxylate sulfates such as those having ethoxylation levels primarily in the range of 1 to about 6, especially about 3. Polyethylene Glycol Glyceryl Fatty Ester Nonionic Surfactant Polyethylene glycol glyceryl fatty ester nonionic surfactant, i.e., PEG glyceryl fatty ester, is a critical element of preferred premixes, shampoos, and processes hereof. They will generally have a degree of polymerization of from about 5 to about 200, and the fatty ester of the surfactant will have an aliphatic hydro- carbyl radical of from about 8 to 20 carbons. The preferred PEG glyceryl fatty esters will generally be of the formula: 0 u RC0CH 2 CH(0H)CH 2 (0CH 2 CH 2 ) n 0H wherein n is from about 5 to about 200, preferably from about 20 to about 100, more preferably from about 30 to about 85, and RC(0)- is an ester wherein R comprises an aliphatic radical having from about 7 to 19 carbon atoms, preferably from about 9 to 17 carbon atoms, more preferably from about 11 to 17 carbon atoms, most preferably from about 11 to 14 carbon atoms. Suitable glyceryl fatty ester portions of these surfactants include glyceryl cocoate, glyceryl tallowate, glyceryl palmate, glyceryl stearate, glyceryl laurate, glyceryl oleate, glyceryl ricinoleate, and glyceryl fatty esters derived from triglycerides, such as palm oil, almond oil, and corn oil. Preferred glyceryl esters include glyceryl tallowate and glyceryl cocoate. Suitable surfactants of this class are commercially available from Sherex Chemical Co. (Dublin, Ohio, USA) under their Varonic ® LI line of surfactants. These include, for example, Varonic LI 48 (polyethylene glycol (n=80) glyceryl tallowate, alternately referred to as PEG 80 glyceryl tallowate), Varonic LI 2 (PEG 28 glyceryl tallowate), Varonic LI 420 (PEG 200 glyceryl tallowate), and Varonic LI 63 and 67 (PEG 30 and PEG 80 glyceryl cocoates), and from Croda, Inc. (New York, New York, USA) under their Crovol ® line of materials, such as Crovol A-40 (PEG 20 almond glyceride, Crovol A-70 (PEG 60 almond glyceride), Crovol M-40 (PEG 20 maize glyceride), Crovol M-70 (PEG 60 maize glyceride), Crovol PK-40 (PEG 12 palm kernel glyceride), and Crovol PK-70 (PEG-45 palm kernel glyceride). Especially preferred are onotallowate and cocoate fatty ester derivatives of polyethylene glycol, or mix¬ tures thereof, particularly materials such as PEG 82 glyceryl monotallowate and PEG 30 glyceryl cocoate, and mixtures thereof. Imidazoliniurn-Type Amphoteric Surfactant The imidazolinium-type amphoteric surfactant hereof can be depicted by Formula I: R 3 R 1 C0N(CH 2 ) n N I+-CH 2 Z (I) R 4 R 2 wherein R 1 is C 8 - C 22 alkyl or alkenyl, preferably C 12 -C 16 , R 2 is hydrogen or CH 2 C0 2 M, R 3 is CH 2 CH 2 0H or CH 2 CH 2 0CH 2 CH 2 C00M, R 4 is hydrogen, CH 2 CH 2 0H, or CH 2 CH 2 0CH 2 CH 2 C00M, Z is C0 2 M or CH 2 C0 2 M, n is 2 or 3, preferably 2, M is hydrogen or a cation, such as alkali metal, alkaline earth metal, or ammonium. Suitable materials of this type are marketed under the tradena e MIRANOL and are understood to comprise a complex mixture of species, and can exist in protonated and non-protonated species depending upon pH with respect to species that can have a hydrogen at R 2 . The amphoteric surfactant hereof can be derived via an imidazoliniurn intermediate, and therefore can be referred to as "imidazolinium-type" amphoteric surfactants. However, it will be recognized by those in the art that the amphoteric surfactant hereof needn't necessarily be derived via an imidazolinium. Preferred amphoteric surfactants of Formula I are onocar- boxylates and dicarboxylates. Examples of these materials include cocoamphocarboxypropionate, cocoamphocarboxy propionic acid, cocoamphocarboxyglycinate (alternately referred to as cocoa pho- diacetate), and cocoamphoacetate. Specific commercial products providing the imidazoliniurn derivative component of the present compositions include those sold under the trade names MIRANOL C2M CONC. N.P., MIRANOL C2M CONC. O.P., MIRANOL C2M SF, MIRANOL CM SPECIAL (Miranol, Inc.); ALKATERIC 2CIB (Alkaril Chemicals); AMPHOTERGE -2 (Lonza, Inc.); MONATERIC CDX-38, MONATERIC CSH-32 (Mona Industries); REWOTERIC AM-2C (Rewo Chemical Group); and SCHERCOTERIC MS-2 (Scher Chemicals) . Suspending Agent Suspending agents useful in the present compositions include those which can exist in the compositions hereof in crystalline form. However, in general, any suspending agent useful for suspending nonvolatile, insoluble silicone fluids and/or particu- late matter (such as particulate antidandruff agents) can be used. Preferred suspending agents are acyl derivatives and amine oxides, especially acyl derivatives, which can be solublized in the shampoo premix solution and then be recrystallized upon cooling. These materials will comprise long chain (e.g., C 8 -C 22 preferably C 16 -C 22 ) aliphatic groups, i.e., long chain acyl derivative materials and long chain amine oxides, as well as mixtures of such materials. In addition to providing a network to support insoluble materials, the suspending agents hereof can also impart pearlescence to the compositions. Whereas it is preferred to include insoluble materials, such as silicone conditioning agents and particulate matter (e.g., antidandruff agents) into the compositions, it is also contemplated that this invention to compositions containing the suspending agents hereof without also containing insoluble materials that need suspending. Such compositions can still benefit by combining mildness and good cleaning and lathering in combination with improved aesthetic appearance, i.e., pearlescence. Examples of suitable suspending agents are described in U.S. Patent 4,741,855, Grote and Russell, issued May 3, 1988, incorpo¬ rated herein by reference. Suitable suspending agents for use herein include ethylene glycol esters of fatty acids preferably having from about 14 to about 22 carbon atoms, more preferably 16-22 carbon atoms. More preferred are the ethylene glycol stearates, both mono and distearate, but particularly the di- stearate containing less than about 7% of the mono stearate. Other suspending agents found useful include alkanol amides of fatty acids, preferably having from about 16 to about 22 carbon atoms, more preferably about 16 to 18 carbon atoms. Preferred alkanol amides are stearic monoethanolamide, stearic diethanol- amide, stearic monoisopropanolamide and stearic monoethanolamide stearate. Other long chain acyl derivatives include long chain esters of long chain fatty acids (e.g., stearyl stearate, cetyl palmitate); glyceryl esters (e.g., glyceryl distearate) and long chain esters of long chain alkanol amides (e.g., steara ide diethanolamide distearate, stearamide monoethanolamide stearate). Ethylene glycol esters of long chain carboxylic acids, long chain amine oxides, and alkanol amides of long chain carboxylic acids, in addition to the preferred materials listed above, may be used as suspending agents. Suspending agents also include long chain amine oxides such as alkyl (C 16 -C 22 ) dimethyl amine oxides, e.g., stearyl dimethyl amine oxide. If the compositions contain an amine oxide or a long chain acyl derivative which is a surfactant, the suspending function could also be provided by such amine oxide or acyl derivative, provided at least a portion of them are present in crystalline form, and additional suspending agent may not be needed. Other long chain acyl derivatives that can be used include N,N-dihydrocarbyl amido benzoic acid and soluble salts thereof (e.g., Na and K salts), particularly N,N-di(hydrogenated) C 16 , C 18 and tallow amido benzoic acid species of this family, which are commercially available from Stepan Company (Northfield, Illinois, USA). The suspending agent serves to assist in suspending the silicone material or other particulate matter in shampoo compositions hereof, and may give pearlescence to the product. The suspending agent can be incorporated into the shampoo premixes hereof by solubilizing it into a solution containing the above described ingredients. The suspending agent is then re¬ crystallized, typically by cooling the solution to a temperature sufficient to induce crystallization. In order to facilitate this, it is highly preferred that the pH of the solution be below 7.0. Preferably the pH is adjusted to levels of from below 7.0 to about 6.0, more preferably from about 6.0 to about 6.5. The pH of the solution, unadjusted, will normally be higher than that, and can be reduced by addition of acids according to known techniques for pH adjustment. Preferably, the pH is adjusted to below pH 7.0 prior to solubilizing the suspending agent, as this can facilitate more rapid solubilization. Suitable pH adjustors include hydro¬ chloric acid, citric acid, sulfuric acid, etc., preferably hydro¬ chloric acid and citric acid. Water The shampoo premixes hereof will also contain water, typically from about 30% to about 70%, by weight, of the premix, preferably from about 30% to about 60%, more preferably from about 40% to about 55%, most preferably from about 45% to about 52%. The premix and shampoo compositions hereof are substantially free of alkyl sulfate surfactants. It is recognized that there will generally be some alkyl sulfate present as a result of it being present in commercially available alkyl ethoxylated sulfate raw materials. For purposes hereof, to be substantially free of alkyl sulfate the premix composition and shampoo compositions hereof should have an alkyl sulfate:alkyl ethoxylated sulfate weight ratio of no more than about 0.35 (preferably no more than about 0.30, more preferably no more than about 0.25) for average ethoxylate levels of 2.5 and higher. For alkyl ethoxylated sulfate with an average ethoxylate level of less than 2.5, the ratio should be no more than about 0.40, preferably no more than about 0.5, more preferably no more than about 0.30, most prefer¬ ably no more than about 0.25. It is preferred that no additional amount of alkyl sulfate be added other than that which occurs inherently with the alkyl ethoxylated sulfate. The use of narrow range ethoxylates to lower the alkyl sulfate.-alkyl ethoxylated sulfate weight ratio is preferred. "Narrow range ethoxylate" refers to alkyl ethoxylated sulfate surfactants that have been processed to reduce alkyl sulfates and optionally alkyl ethoxy¬ lated sulfates outside of the desired range of ethoxyulation. The use of narrow range ethoxylates can be used to lower the alkyl sulfate:alkyl ethoxylated sulfate weight ratio to the preferred levels hereof, including to levels as low as about 0.2 or even about 0.1, and less. It is also preferred that no other ingredients that are harsh to the skin or cause undue eye irritation, such as amide foam boosters (e.g., cocomonoethanolamide, CMEA), be added to the premix or shampoo compositions hereof or be present at levels that significantly increase skin or eye irritation.

Typically, the solution will be heated to from about 60°C to about 85°C, preferably from about 65T to about 80 β C, more prefer¬ ably about 65"C to about 75°C, to solubilize suspending agent which has been added in crystalline form. Alternately, the solution can be first heated, and then the suspending agent can be added to it in either solubilized or crystalline form. As used herein "solubilized" suspending agent, suspending agent in "solu¬ bilized form", and "solubilizing" the suspending agent shall include solubilization, emulsification, and/or melting of the suspending agent. The temperature required for solubilization of the suspending agent will vary according to the particular surfac¬ tants and levels chosen, as well as the level of and selection of particular suspending agent. These factors will also affect the temperature to which the premix must be cooled to induce crystal¬ lization. For example, higher levels of alkyl ethoxylated sulfate and lower levels of imidazoliniurn and/or PEG glyceryl fatty ester will generally require lower crystallization temperature. Typi¬ cally, the composition will be cooled to between about 15°C and about 60 β C, preferably between about 20°C and about 55°C, more preferably from about 20"C to about 45°C, most preferably from about 30 β C to about 45 β C. Preferably, the pH is adjusted prior to solubilization of the suspending agent, as this aids solubilization and can shorten processing time.

Additional examples of anionic surfactants which come within the terms of the present invention are the reaction products of fatty acids esterified with isethionic acid and neutralized with sodium hydroxide where, for example, the fatty acids are derived from coconut oil; sodium or potassium salts of fatty acid amides of methyl tauride in which the fatty acids, for example, are derived from coconut oil. Other anionic synthetic surfactants of this variety are set forth in U.S. Patents 2,486,921; 2,486,922; and 2,396,278, incorporated by reference herein. Still other anionic surfactants include the class designated as succinamates.

Other suitable anionic surfactants utilizable herein are olefin sulfonates having about 12 to about 24 carbon atoms. The term "olefin sulfonates" is used herein to mean compounds which can be produced by the sulfonation of α-olefins by means of unco plexed sulfur trioxide, followed by neutralization of the acid reaction mixture in conditions such that any sulfones which have been formed in the reaction are hydrolyzed to give the corresponding hydroxy-al anesulfonates. The sulfur trioxide can be liquid or gaseous, and is usually, but not necessarily, diluted by inert diluents, for example by liquid SO2, chlorinated hydro¬ carbons, etc., when used in the liquid form, or by air, nitrogen, gaseous SO2, etc., when used in the gaseous form. The α-olefins from which the olefin sulfonates are derived are ono-olefins having about 12 to about 24 carbon atoms, pre¬ ferably about 14 to about 16 carbon atoms. Preferably, they are straight chain olefins. Examples of suitable 1-olefins include 1-dodecene; 1-tetradecene; 1-hexadecene; 1-octadecene; 1-eicosene and 1-tetracosene. In addition to the true alkene sulfonates and a proportion of hydroxy-alkanesulfonates, the olefin sulfonates can contain minor amounts of other materials, such as alkene disulfonates depending upon the reaction conditions, proportion of reactants, the nature of the starting olefins and impurities in the olefin stock and side reactions during the sulfonation process. A specific α-olefin sulfonate mixture of the above type is described more fully in the U.S. Patent 3,332,880, Pflaumer and Kessler, issued July 25, 1967, incorporated herein by reference. Another class of anionic surfactants are the l-alkyloxy alkane sulfonates. These compounds have the following formula: OR2 H I I Rl - C - C - SO3M I I H H where Ri is a straight chain alkyl group having from about 6 to about 20 carbon atoms, R2 is a lower alkyl group having from about 1 (preferred) to about 3 carbon atoms, and M is a water-soluble cation as hereinbefore described.

Many additional synthetic anionic surfactants are described in McCutcheon's, Emulsifiers and Detergents, 1989 Annual, pub¬ lished by M. C. Publishing Co., which is incorporated herein by reference. Also U.S. Patent 3,929,678, Laughlin et al . , issued December 30, 1975, discloses many other anionic as well as other surfactant types and is incorporated herein by reference. Soaps, of course, also fall within the scope of anionic detersive surfactants that can be used. Nonionic Surfactants Nonionic surfactants in addition to the PEG glyceryl fatty esters can be used as detersive surfactants. They are preferably used in combination with an anionic, amphoteric, or zwitterionic surfactant, or mixtures thereof. Nonionic surfactants include those broadly defined as compounds produced by the condensation of alkylene oxide groups (hydrophilic in nature) with an organic hydrophobic compound, which may be aliphatic or alkyl aromatic in nature. Examples of classes of nonionic surfactants are: 1. The polyethylene oxide condensates of alkyl phenols, e.g., the condensation products of alkyl phenols having an alkyl group containing from about 6 to about 20 carbon atoms, preferably from about 6 to about 12, in either a straight chain or branched chain configuration, with ethylene oxide, the said ethylene oxide being present in amounts equal to from about 10 to about 60 moles of ethylene oxide per mole of alkyl phenol. The alkyl substituent in such compounds may be derived from polymerized propylene, diisobutylene, octane, or nonane, for example. 2. Those derived from the condensation of ethylene oxide with the product resulting from the reaction of propylene oxide and ethylene diamine products which may be varied in composition depending upon the balance between the hydrophobic and hydrophilic elements which is desired. For example, compounds containing from about 40% to about 80% polyoxyethylene by weight and having a molecular weight of from about 5,000 to about 11,000 resulting from the reaction of ethylene oxide groups with a hydrophobic base constituted of the reaction product of ethylene diamine and excess propylene oxide, said base having a molecular weight of the order of about 2,500 to about 3,000, are satisfactory. 3.

The intersaccharide bonds can be, e.g., between the one position of the additional saccharide units and the 2-, 3-, 4-, and/or 6-positions on the preceding saccharide units. Optionally, and less desirably, there can be a polyalkylene- oxide chain joining the hydrophobic moiety and the polysaccharide moiety. The preferred alkyleneoxide is ethylene oxide. Typical hydrophobic groups include alkyl groups, either saturated or unsaturated, branched or unbranched containing from about 8 to about 18, preferably from about 10 to about 16, carbon atoms. Preferably, the alkyl group is a straight chain saturated alkyl group.

To prepare these compounds, the alcohol or alkylpoly- ethoxy alcohol is formed first and then reacted with glucose, or a source of glucose, to form the glucoside (attachment at the 1-position). The additional glycosyl units can then be attached between their 1-position and the preceding glycosyl units 2-, 3-, 4- and/or 6-position, preferably predominantly the 2-position.

The compositions are prepared as follows. A silicone premix is first prepared by adding a small portion (e.g., about 0.2% by weight of the finished product) of the sodium laureth-3 sulfate to the premix tank and heating to 71"C. The sodium chloride is added. The dimethicone is added and mixed until an emulsion is formed. A portion of the sodium laureth-3 sulfate, the Varonic LI-63, and the cocoamphodiacetate are placed in a tank. The mixture (the "main premix") is agitated and heated to 71°C. The citric acid in the form of a 50% active solution is added to adjust pH. The ethylene glycol distearate is then added and allowed to melt. The premix has a weight ratio of ingredients, in the order listed in this paragraph, of about 4:4:7:1:4. The main mix is passed through a heat exchanger where it is cooled to 38 β C and collected in a finishing tank. As a result of this cooling step, the ethylene glycol distearate has crystallized to form a crystalline network in the product. The silicone premix is collected in the same finishing tank, where the main premix and the silicone premix are mixed until homogeneous. Finally, the remainder of the ingredients are added and mixed into the shampoo composition. The composition comprises about 22%, by weight, of the main premix. The final pH is adjusted by the citric acid to within the range of 6.3 - 6.8. The compositions of the Examples can provide excellent in-use hair cleaning and conditioning, along with high silicone hair conditioning agent efficiency.

The compositions are prepared as follows. A silicone premix is first prepared by adding a small portion (e.g., about 0.2% by weight of the finished product) of the sodium laureth-3 sulfate to the premix tank and heating to 71°C. The cetyl and stearyl alcohols, as applicable, are added. The dimethicone is then added and mixed until an emulsion is formed. For Examples VI and IX, about one-third of the sodium laureth-3 sulfate, the cocoamphodiacetate and/or cocoamphoacetate, the CAPB and TCMAC, as applicable, are placed in a tank. The mixture (the "main premix") is agitated and heated to 71°C. The ethylene glycol distearate is then added and allowed to melt. The citric acid in the form of a 50% active solution is added to adjust pH. The main mix is passed through a heat exchanger where it is cooled to 32 β C and collected in a finishing tank. As a result of this cooling step, the ethylene glycol distearate crystallizes to form a crystalline network in the product. The Polyquaternium 10, if applicable, is then added as a solid or predissolved in water to the main premix. For Examples VII, VIII, and X, the CAPB is mixed into the main premix after the ethylene glycol distearate has been crystallized instead of being added at the above-indicated earlier stage. The silicone premix is col¬ lected in the same finishing tank after being cooled to about 30 β C, where the main premix and the silicone premix are mixed until homogeneous. Finally, the remainder of the ingredients are added and mixed into the shampoo composition. The final pH is adjusted as desired by the addition of citric acid and/or NaOH. The final viscosity is adjusted as desired by the addition of ammonium xylene sulfonate and/or NaCl, The compositions of the Examples can provide excellent in-use hair cleaning, lather, mildness, conditioning and dandruff control (where applicable), and pearlescence.
