Description: HAIR CARE COMPOSITIONS The present invention relates to hair care compositions. In particular, it relates to hair care compositions comprising certain amino acid compounds. Background to the Invention Hair is often subjected to a wide variety of insults that can cause weakening and damage. These include shampooing, rinsing, drying, heating, combing, styling, perming, colouring, exposure to the elements etc. Thus the hair is often in a dry, rough, lusterless or frizzy condition due to abrasion of the hair surface and removal of the hair's natural oils and other natural conditioning and moisturizing components. A variety of approaches have been developed to alleviate these conditions. These include the use of ultra mild shampoo compositions, the use of hair conditioning shampoos which attempt to both cleanse and condition the hair from a single product and the use of hair conditioning formulations such as rinse-off, leave-on or heat activated products. See, for example, EP-A-181 ,773, WO-A-97/35542, WO-A-97/35545, WO-A-97/35546, all of which describe conditioning shampoo compositions. It has been suggested that amino acids may be used in hair care compositions for providing a variety of benefits. For example, US-A-4,201 ,235 describes compositions comprising various amino acids that enhance the luster and softness of the hair. JP-A-57/109711 describes compositions comprising amino acids which improve the combing properties of the hair. DE-A-1 ,617,477 describes hair tonic with guaranteed hair growth comprising certain amino acids. JP-A-59/078114 describes compositions for imparting a smooth feeling to the hair containing amine oxide compounds and amino acids having an isoelectric point of 7 or lower. It has been found that the levels of certain amino acids are reduced in damaged hair in comparison with undamaged hair. In particular, it has been found that cysteine, tyrosine, lysine, histidine, methionine and tryptophan are at reduced levels in damaged hair. Surprisingly, it has been found that compositions comprising a tyrosine compound and at least one other amino acid compound selected from tryptophan compounds, histidine compounds and lysine compounds can improve the strength and condition of the hair. Summary of the Invention According to the present invention there is provided a hair care composition comprising at least one tyrosine compound and at least one other amino acid compound selected from tryptophan compounds, histidine compounds and lysine compounds.

Any cosmetically acceptable conditioning agent may be used in the compositions of the present invention. However, preferred conditioning agents for use in the present compositions include, but are not limited to, silicone conditioning agents and cationic conditioning agents. Silicone Conditioning Component The compositions of the present invention may optionally include a silicone conditioning component. The silicone conditioning component can comprise any suitable silicone conditioning agent but will generally comprise a silicone fluid conditioning agent, and can also comprise other ingredients, such as a silicone resin to enhance silicone fluid deposition efficiency or enhance glossiness of the hair (especially when high refractive index (e.g. above about 1.46 silicone conditioning agents are used (e.g. highly phenylated silicones)). Preferably the silicone is non-volatile, however volatile silicones are not excluded from use herein. As used herein, "nonvolatile" refers to silicone material with little or no significant vapour pressure under ambient conditions, as is understood by those in the art. Boiling point under one atmosphere (atm) will preferably be at least about 250° C, more preferably at least about 275°C, most preferably at least about 300°C. Vapour pressure is preferably about 0.2mm Hg at 25°C or less, preferably about 0.1 mm Hg at 25°C or less. The silicone conditioning agent phase may comprise volatile silicone, nonvolatile silicone, or mixtures thereof. Typically, if volatile silicones are present, it will be incidental to their use as a solvent or carrier for commercially available forms of nonvolatile silicone materials ingredients, such as silicone gums and resins. The silicone conditioning agents for use in the compositions of the present invention will preferably have a viscosity of from about 20 to about 2,000,000 centistokes, more preferably from about 1 ,000 to about 1 ,800,000 centistokes, even more preferably from about 10,000 to about 1 ,500,000 centistokes, most preferably from about 30,000 to about 1 ,000,000 centistokes, at 25°C. The viscosity can be measured by means of a glass capillary viscometer as set forth in Dow Corning Corporate Test Method CTM0004, July 20, 1970. Silicone fluid for use in the present compositions include silicone oils which are flowable silicone materials with a viscosity of less than 1 ,000,000 centistokes, preferably between about 5 and 1 ,000,000 centistokes, more preferably between about 10 and about 600,000 centistokes, more preferably between about 10 and about 500,000 centistokes, most preferably between 10 and 350,000 centistokes at 25°C. Suitable silicone oils include, but are not limited to, polyalkyl siloxanes, polyaryl siloxanes, polyalkylaryl siloxanes, polyether siloxane copolymers, and mixtures thereof. Other insoluble, nonvolatile silicone fluids having conditioning properties can also be used. Silicone oils for use in the composition include polyalkyl or polyaryl siloxanes which conform to following formula: where R is aliphatic, preferably alkyl or alkenyl, or aryl, R can be substituted or unsubstituted, and x is an integer from 1 to about 8,000. Suitable unsubstituted R groups include alkoxy, aryloxy, alkaryl, arylalkyl, arylalkenyl, alkamino, and ether-substituted, hydroxyl-substituted, and halogen-substituted aliphatic and aryl groups. Suitable R groups also include cationic amines and quaternary ammonium groups. The aliphatic or aryl groups substituted on the siloxane chain may have any structure as long as the resulting silicones remain fluid at room temperature, are hydrophobic, are neither irritating, toxic nor otherwise harmful when applied to the hair, are compatible with the other components of the herein described compositions, are chemically stable under normal use and storage conditions, are insoluble in the compositions of the present invention, and are capable of being deposited on, and of conditioning, the hair. The two R groups on the silicon atom of each monomeric silicone unit may represent the same group or different groups. Preferably, the two R groups represent the same group. Preferred alkyl and alkenyl substituents are C C 5 alkyls and alkenyls, more preferably from Cι-C 4 , most preferably from C C 2 . The aliphatic portions of other alkyl-, alkenyl-, or alkynyl-containing groups (such as alkoxy, alkaryl, and alkamino) can be straight or branched chains and preferably have from one to five carbon atoms, more preferably from one to four carbon atoms, even more preferably from one to three carbon atoms, most preferably from one to two carbon atoms. As discussed above, the R substituents hereof can also contain amino functionalities, e.g. alkamino groups, which can be primary, secondary or tertiary amines or quaternary ammonium. These include mono-, di- and tri- alkylamino and alkoxyamino groups wherein the aliphatic portion chain length is preferably as described above. The R substituents can also be substituted with other groups, such as halogens (e.g. chloride, fluoride, and bromide), halogenated aliphatic or aryl groups, and hydroxy (e.g. hydroxy substituted aliphatic groups). Suitable halogenated R groups could include, for example, tri- halogenated (preferably fluoro) alkyl groups such as -R 1 -C(F) 3 , wherein R 1 is C C 3 alkyl. Examples of such polysiloxanes include polymethyl -3,3,3 trifluoropropylsiloxane. Suitable R groups include methyl, ethyl, propyl, phenyl, methylphenyl and phenylmethyl. The preferred silicones are polydimethyl siloxane, polydiethylsiloxane, and polymethylphenylsiloxane. Polydimethylsiloxane is especially preferred. Other suitable R groups include methyl, methoxy, ethoxy, propoxy, and aryloxy. The three R groups on the end caps of the silicone may also represent the same or different groups. The nonvolatile polyalkylsiloxane fluids that may be used include, for example, polydimethylsiloxanes. These siloxanes are available, for example, from the General Electric Company in their Viscasil R and SF 96 series, and from Dow Corning in their Dow Corning 200 series. The polyalkylaryl siloxane fluids that may be used, also include, for example, polymethylphenylsiloxanes. These siloxanes are available, for example, from the General Electric Company as SF 1075 methyl phenyl fluid or from Dow Corning as 556 Cosmetic Grade Fluid. The polyether siloxane copolymers that may be used include, for example, a polypropylene oxide modified polydimethylsiloxane (e.g., Dow Corning DC-1248) although ethylene oxide or mixtures of ethylene oxide and propylene oxide may also be used. For insoluble silicones the ethylene oxide and polypropylene oxide level must be sufficiently low to prevent solubility in water and the composition hereof. Other suitable silicone fluids for use in the silicone conditioning agents are insoluble silicone gums. These gums are polyorganosiloxane materials having a viscosity at 25°C of greater than or equal to 1 ,000,000 centistokes. Silicone gums are described in U.S. Patent 4,152,416; Noll and Walter, Chemistry and Technology of Silicones, New York: Academic Press 1968; and in General Electric Silicone Rubber Product Data Sheets SE 30, SE 33, SE 54 and SE 76. The silicone gums will typically have a mass molecular weight in excess of about 200,000, generally between about 200,000 and about 1 ,000,000, specific examples of which include polydimethylsiloxane, (polydimethylsiloxane) (methylvinylsiloxane) copolymer, poly(dimethylsiloxane) (diphenyl siloxane)(methylvinylsiloxane) copolymer and mixtures thereof. The silicone conditioning agent can also comprise a mixture of polydimethylsiloxane gum (viscosity greater than about 1 ,000,000 centistokes) and polydimethylsiloxane oil (viscosity from about 10 to about 100,000 centistokes), wherein the ratio of gum to fluid is from about 30:70 to about 70:30, preferably from about 40:60 to about 60:40. References disclosing examples of some suitable silicone fluids for use in the present compositions include U.S. Patent 2,826,551 , U.S. Patent 3,964,500, U.S. Patent 4,364,837, British Patent 849,433, and Silicon Compounds, Petrarch Systems, Inc. (1984). The silicone conditioning agent suitable for use in the present compositions can comprise silicone resins. These resins are highly crosslinked polymeric siloxane systems. The crosslinking is introduced through the incorporation of trifunctional and tetrafunctional silanes with monofunctional or difunctional, or both, silanes during manufacture of the silicone resin. As is well understood in the art, the degree of crosslinking that is required in order to result in a silicone resin will vary according to the specific silane units incorporated into the silicone resin. In general, silicone materials which have a sufficient level of trifunctional and tetrafunctional siloxane monomer units (and hence, a sufficient level of crosslinking) such that they dry down to a rigid, or hard, film are considered to be silicone resins. The ratio of oxygen atoms to silicon atoms is indicative of the level of crosslinking in a particular silicone material. Silicone materials which have at least about 1.1 oxygen atoms per silicon atom will generally be silicone resins herein. Preferably, the ratio of oxygen:silicon atoms is at least about 1.2:1.0. Silanes used in the manufacture of silicone resins include monomethyl-, dimethyl-, trimethyl-, monophenyl-, diphenyl-, methylphenyl-, monovinyl-, and methylvinyl-chlorosilanes, and tetrachlorosilane, with the methyl-substituted silanes being most commonly utilized. Preferred resins are offered by General Electric as GE SS4230 and SS4267. Commercially available silicone resins will generally be supplied in a dissolved form in a low viscosity volatile or nonvolatile silicone fluid. The silicone resins for use herein should be supplied and incorporated into the present compositions in such dissolved form, as will be readily apparent to those skilled in the art. Background material on silicones including sections discussing silicone fluids, gums, and resins, as well as manufacture of silicones, can be found in Encyclopedia of Polymer Science and Engineering, Volume 15, Second Edition, pp. 204-308, John Wiley & Sons, Inc., 1989. Silicone materials and silicone resins in particular, can conveniently be identified according to a shorthand nomenclature system well known to those skilled in the art as "MDTQ" nomenclature. Under this system, the silicone is described according to presence of various siloxane monomer units which make up the silicone. Briefly, the symbol M denotes the monofunctional unit (CH 3 ) 3 SiO 0.5 ; D denotes the difunctional unit (CH 3 ) 2 SiO; T denotes the trifunctional unit (CH 3 )SiO-ι.5; and Q denotes the quadri- or tetra-functional unit Si0 2 . Primes of the unit symbols, e.g., M', D\ T\ and Q' denote substituents other than methyl, and must be specifically defined for each occurrence. Typical alternate substituents include groups such as vinyl, phenyls, amines, hydroxyls, etc. The molar ratios of the various units, either in terms of subscripts to the symbols indicating the total number of each type of unit in the silicone (or an average thereof) or as specifically indicated ratios in combination with molecular weight complete the description of the silicone material under the MDTQ system. Higher relative molar amounts of T, Q, T' and/or Q' to D, D', M and/or M' in a silicone resin is indicative of higher levels of crosslinking. As discussed before, however, the overall level of crosslinking can also be indicated by the oxygen to silicon ratio. The silicone resins for use herein which are preferred are MQ, MT, MTQ, MDT and MDTQ resins. Thus, the preferred silicone substituent is methyl. Especially preferred are MQ resins wherein the M:Q ratio is from about 0.5:1.0 to about 1.5:1.0 and the average molecular weight of the resin is from about 1000 to about 10,000. The weight ratio of the nonvolatile silicone fluid, having refractive index below 1.46, to the silicone resin component, when used, is preferably from about 4:1 to about 400:1 , preferably this ratio is from about 9:1 to about 200:1 , more preferably from about 19:1 to about 100:1. Insofar as the silicone resin forms a part of the same phase in the compositions hereof as the silicone fluid, i.e. the conditioning active, the sum of the fluid and resin should be included in determining the level of silicone conditioning agent in the composition. The number average particle size of the optional silicone component can vary widely without limitation and will depend on the formulation and/or the desired characteristics. Number average particle sizes preferred for use in the present invention will typically range from about 10 nanometers to about 100 microns, more preferably from about 30 nanometers to about 20 microns. Cationic Conditioning Component The compositions of the present invention may optionally comprise a cationic conditioning component. The cationic conditioning component may comprise any suitable cationic conditioning agent or mixtures of cationic conditioning agents. Preferred cationic conditioning agents for use herein include, but are not limited to, polymeric cationic conditioning agents. Preferably the cationic polymer conditioning agent will preferably be water soluble. The total level of cationic polymers in the compositions of the present invention is typically from about 0.001 % to about 20%, more typically from about 0.005% to about 10%, preferably from about 0.01 % to about 2%, by weight. By "water soluble" cationic polymer, what is meant is a polymer which is sufficiently soluble in water to form a substantially clear solution to the naked eye at a concentration of 0.1 % in water (distilled or equivalent) at 25°C. Preferably, the polymer will be sufficiently soluble to form a substantially clear solution at 0.5% concentration, more preferably at 1.0% concentration. As used herein, the term "polymer" shall include materials whether made by polymerisation of one type of monomer or made by two (i.e., copolymers) or more types of monomers. The cationic polymers hereof will generally have a weight average molecular weight which is at least about 5,000, typically at least about 10,000, and is less than about 10 million. Preferably, the molecular weight is from about 100,000 to about 2 million. The cationic polymers will generally have cationic nitrogen- containing moieties such as quaternary ammonium or cationic amino moieties, and mixtures thereof. The cationic charge density will be preferably at least about 0.1 meq/g, more preferably at least about 0.5 meq/g, even more preferably at least about 1.1 meq/g, most preferably at least about 1.2 meq/g. Generally, for practical purposes, the cationic polymers will have a cationic charge density of less than about 7meq/g, preferably less than about 5meq/g, more preferably less than about 3.5meq/g, even more preferably less than about 2.5meq/g. Cationic charge density of the cationic polymer can be determined using the Kjeldahl Method (United States Pharmacopoeia - Chemical tests - <461> Nitrogen Determination - method II). Those skilled in the art will recognise that the charge density of amino-containing polymers may vary depending upon pH and the isoelectric point of the amino groups. The charge density should be within the above limits at the pH of intended use. Any anionic counterions can be utilized for the cationic polymers so long as the water solubility criteria is met. Suitable counterions include halides (e.g., Cl, Br, I, or F, preferably Cl, Br, or I), sulfate, and methyl su If ate. Others can also be used, as this list is not exclusive. The cationic nitrogen-containing moiety will be present generally as a substituent, on a fraction of the total monomer units of the cationic hair conditioning polymers. Thus, the cationic polymer can comprise copolymers, terpolymers, etc. of quaternary ammonium or cationic amine-substituted monomer units and other non-cationic units referred to herein as spacer monomer units. Such polymers are known in the art, and a variety can be found in the CTFA International Cosmetic Ingredient Dictionary and Handbook, 7th edition, edited by Wenninger and McEwen, (The Cosmetic, Toiletry, and Fragrance Association, Inc., Washington, D.C., 1997).

Amine-substituted vinyl monomers can be polymerised in the amine form, and then optionally can be converted to ammonium by a quaternization reaction. Amines can also be similarly quaternized subsequent to formation of the polymer. For example, tertiary amine functionalities can be quaternized by reaction with a salt of the formula R'X wherein R' is a short chain alkyl, preferably a C 1 -C 7 alkyl, more preferably a CrC 3 alkyl, and X is an anion which forms a water soluble salt with the quaternized ammonium.

Preferably however, the cationic polymer is either soluble in the composition, or in a complex coacervate phase in the composition formed by the cationic polymer and anionic material. Complex coacervates of the cationic polymer can be formed with anionic surfactants or with anionic polymers that can optionally be added to the compositions hereof (e.g. sodium polystyrene sulfonate).

Surfactant systems useful herein can comprise one or more surfactants selected from anionic surfactants, amphoteric surfactants, nonionic surfactants, cationic surfactants and mixtures thereof. Amphoteric surfactant components useful in the present composition include those known to be useful in personal cleansing compositions, and which, preferably, contain a group that is anionic at the pH of the compositions of the present invention. The active concentration of such surfactant components in the surfactant system of the present invention preferably ranges from about 0.001 % to about 20%, more preferably from about 0.01 % to about 15%, and most preferably from about 0.1% to about 10% by weight of the surfactant system. Examples of amphoteric surfactants suitable for use in the composition herein are described in U.S. Patents 5,104,646 (Bolich Jr. et al.) and U.S. Patent 5,106,609 (Bolich Jr. et al.). Examples of amphoteric detersive surfactants which can be used in the compositions of the present invention are those which are broadly described as derivatives of aliphatic secondary and tertiary amines in which the aliphatic radical can be straight or branched chain and wherein one of the aliphatic substituents contains from about 8 to about 18 carbon atoms and one contains an anionic water solubilizing group, e.g., carboxy, sulfonate, sulfate, phosphate, or phosphonate. Examples of compounds falling within this definition are sodium 3-dodecyl-aminopropionate, sodium 3- dodecylaminopropane sulfonate, sodium lauroamphoacetate, N-alkyltaurines such as the one prepared by reacting dodecylamine with sodium isethionate according to the teaching of U.S. Patent 2,658,072, N-higher alkyl aspartic acids such as those produced according to the teaching of U.S. Patent 2,438,091 , and the products sold under the trade name "MIRANOL™" and described in U.S. Patent 2,528,378. Other amphoterics, sometimes classified as zwitterionics, such as betaines can also be used in the present invention. Such zwitterionics are considered as amphoterics in the present invention where the zwitterionic has an attached group that is anionic at the pH of the composition.

Most preferred for use herein is cocoamidopropyl betaine. Anionic surfactants suitable for use in the present invention include alkyl sulfate, alkyl ethoxylated sulfate, or a mixture thereof. These materials have the respective formulae (I) ROSO 3 M and (II) RO(C 2 H 4 0) x S0 3 M, wherein R is alkyl or alkenyl of from about 8 to about 30 carbon atoms, x is 1 to 10, and M is H or a salt-forming cation such as ammonium, alkanolamine containing C 1 -C 3 alkyl groups such as triethanolamine, and monovalent and polyvalent metals such as the alkaline and alkaline earth metals. Preferred metals include sodium, potassium, magnesium, and calcium. The cation M, of the anionic surfactant should preferably be chosen such that the anionic surfactant component is water soluble. Solubility of anionic surfactants, in general, will depend upon the particular anionic surfactants and cations chosen. As an aid to determining appropriate mixtures of anionic surfactants, the anionic surfactants should be chosen such that the Krafft temperature is about 15°C or less, preferably about 10°C or less, more preferably about 0°C or less. It is also preferred that the anionic surfactant be soluble in the composition hereof. Preferably, R has from about 10 to about 18 carbon atoms in both the alkyl and alkyl ethoxylated sulfates. The alkyl ethoxylated sulfates are typically made as condensation products of ethylene oxide and monohydric alcohols having from about 8 to about 24 carbon atoms. The alcohols can be derived from fats, e.g., coconut oil, palm kernel oil, or tallow, or can be synthetic. Such alcohols are preferably reacted with about 1 to about 10, more preferably from about 1 to about 4, most preferably from about 2 to about 3.5, molar proportions of ethylene oxide and the resulting mixture of molecular species having, for example, an average of 3 moles of ethylene oxide per mole of alcohol, is sulfated and neutralised. Specific examples of alkyl ether sulfates which may be used in the present invention are sodium and ammonium salts of coconut alkyl triethylene glycol ether sulfate; tallow alkyl triethylene glycol ether sulfate, and tallow alkyl hexaoxyethylene sulfate. Highly preferred alkyl ether sulfates are those comprising 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 1 to about 4 moles of ethylene oxide. The sulfate surfactant is preferably comprised of a combination of ethoxylated and nonethoxylated sulfates. Alkyl sulfates can provide excellent cleaning and lather performance. Alkyl ethoxylated sulfates can provide excellent cleaning performance. Other suitable anionic detersive surfactants include, but are not limited to water- soluble salts of organic, sulfuric acid reaction products of the general formula [R 1 -SO 3 -M] where R 1 is selected from the group consisting of a straight or branched chain, saturated aliphatic hydrocarbon radical having from about 8 to about 24, preferably about 10 to about 18, carbon atoms; and M is a cation such as ammonium, alkanolamines, such as triethanolamine, monovalent metals, such as sodium and potassium, and polyvalent metal cations, such as magnesium, and calcium. The cation M, of the anionic detersive surfactant should be chosen such that the detersive surfactant component is water soluble. Solubility will depend upon the particular anionic detersive surfactants and cations chosen. Examples of such detersive surfactants are the salts of an organic sulfuric acid reaction product of a hydrocarbon of the methane series, including iso-, neo-, and n-paraffins, having about 8 to about 24 carbon atoms, preferably about 10 to about 18 carbon atoms and a sulfonating agent, e.g., S0 3 , H 2 S0 4 , obtained according to known sulfonation methods, including bleaching and hydrolysis. Preferred are alkali metal and ammonium sulfonated C-ιo-18 n-paraffins. Another class of anionic detersive surfactants suitable for use in the present invention are the reaction products of fatty acids esterified with isethionic acid and neutralised with sodium hydroxide where, for example, the fatty acids are derived from coconut oil or palm kernal oil; sodium, ammonium, tetraethylammonium or potassium salts of fatty acid amides of methyl tauride in which the fatty acids, for example, are derived from coconut oil or palm kernal oil. Other similar anionic surfactants are described in U.S. Patent 2,486,921 ; U.S. Patent 2,486,922; and U.S. Patent 2,396,278. Other anionic detersive surfactants suitable for use in the present invention are the succinnates, examples of which include disodium N- octadecylsulfosuccinnate; disodium lauryl sulfosuccinate; diammonium lauryl sulfosuccinate; tetrasodium N-(1 ,2-dicarboxyethyl)-N-octadecylsulfosuccinnate; diamyl ester of sodium sulfosuccinic acid; dihexyl ester of sodium sulfosuccinic acid; dioctyl esters of sodium sulfosuccinic acid. Other suitable anionic detersive surfactants include alkyl glyceryl ether sulfonate surfactants (also referred to herein as an "AGS" surfactant), derivatives thereof and salts thereof. These AGS surfactants are derived from an alkyl glyceryl ether containing a sulfonate or sulfonate salt group. These compounds generally can be described as an alkyl monoether of glycerol that also contains a sulfonate group. These AGS surfactants can be described as generally conforming to the following structures: ROCH 2 CHCH 2 S0 3 -X + OH HOCH 2 CHCH 2 S0 3 -X + I OR wherein R is a saturated or unsaturated straight chain, branched chain, or cyclic alkyl group having from about 10 to about 18 carbon atoms, preferably from about 11 to about 16 carbon atoms, and most preferably from about 12 to about 14 carbon atoms, and X is a cation selected from the group consisting of ammonium; mono-alkylsubstituted ammonium; di-alkylsubstituted ammonium; tri-alkylsubstituted ammonium; tetra-alkylsubstituted ammonium; alkali metal; alkaline metal; and mixtures thereof. More preferably, the alkyl radicals, R in the above formulas, are saturated and straight chain. Without being limited by theory, it is believed that the distribution of alkyl chain lengths in the AGS surfactant has some effect on the character of the overall cleansing composition. A satisfactory distribution can be achieved in a commercially practicable way by using fatty alcohols derived from coconut oil and tallow. An equivalent distribution of alkyl chain lengths can be achieved using other starting materials. In the preparation of the coconut fatty alcohols used to provide the alkyl group of the AGS, preferably the middle cut of the coconut oil is taken. The higher boiling cut can be retained with the middle cut coconut oils if desired. In the preparation of the tallow fatty alcohols, a hydrogenation step is included to insure that they are substantially saturated. Preferred AGS compounds are those where the alkyl group is derived from at least about 50% from alcohols of about 10 to about 18 carbons, having mainly monoglyceryl radicals present, with less than about 30% of diglyceryl radicals present. The term "AGS" is intended to include monoglyceryl, diglyceryl, and traces of the higher glyceryl compounds. Small amounts, that is less than about 3% total, of triglyceryl ether sulfonates and tetraglyceryl ether sulfonates can be present. Also included are AGS's derived from glyceryl ethers having branched or mixed branched and straight chain lengths that emulate the straight chain lengths. The AGS surfactants useful in the present invention are more fully described in U.S. Patent No. 2,979,465, to Parran et al., issued April 11 , 1961 ; U.S. Patent No. 3,179,599, to Eaton et al., issued April 20, 1965; British Patent No. 848,224, published Sept. 14, 1960; British Patent No. 791 ,415, published March 5, 1958; U.S. Patent No. 5,322,643, to Schwartz et al., issued June 21 , 1994; and U.S. Patent No. 5,084,212, to Farris et al. issued Jan. 28, 1992. These references also disclose various cleansing products in which the AGS surfactant of this invention can be used. Still other suitable anionic detersive surfactants include olefin sulfonates having about 10 to about 24 carbon atoms. The term "olefin sulfonates" is used herein to mean compounds which can be produced by the sulfonation of alpha-olefins by means of uncomplexed 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-alkanesulfonates. The sulfur trioxide can be liquid or gaseous, and is usually, but not necessarily, diluted by inert diluents, for example by liquid S0 2 , chlorinated hydrocarbons, etc., when used in the liquid form, or by air, nitrogen, gaseous S0 2 , etc., when used in the gaseous form. The alpha-olefins from which the olefin sulfonates are derived are mono-olefins having about 10 to about 24 carbon atoms, preferably about 12 to about 16 carbon atoms. Preferably, they are straight chain olefins. 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 alpha-olefin sulfonate mixture of the above type is described more fully in the U.S. Patent 3,332,880. Another class of anionic detersive surfactants suitable for use in the present invention are the beta-alkyloxy alkane sulfonates. These compounds have the following formula: where R 1 is a straight chain alkyl group having from about 6 to about 20 carbon atoms, R 2 is a lower alkyl group preferably having from about 1 to about 3 carbon atoms, and M is a water-soluble cation as described hereinabove.

If present, the anionic detersive surfactants are preferably present in the surfactant system of the present invention at total active concentration level of from about 3% to about 30%, preferably from about 4% to about 20%, most preferably from about 6% to about 17%. Another class of anionic surfactants is fatty acid soaps. Though useful to the present invention, high concentrations of these surfactants in the presence of hard water tend to result in significant build-up on the hair and skin, adversely affecting cleansing and hair and skin feel. Accordingly, if added to the compositions of the present invention, the level of the fatty acid soaps is preferably incorporated at concentration levels of less than about 3%, more preferably less than about 1 %. Surfactant systems useful in the present invention may also include nonionic surfactants, cationic surfactants, and combinations thereof. Suitable classes of nonionic surfactants include, but are not limited to: 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 12 carbon atoms 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 polymerised 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.
