Full Text	FORM2 THE PATENTS ACT, 1970 (39 Of 1970) COMPLETE SPECIFICATION (See section 10; rule 13) Title of the invention LEAVE-ON OR RINSE-OUT HAIR CARE CONDITION CO MPOSITIONS CONTAINING SILICONE QUATERNARY COMPOUNDS AND CATIONIC THICKENERS HINDUSTAN LEVER LIMITED, a company incorporated under the Indian Companies Act, 1913 having its registered office at Hindustan Lever House, 165/166, Backbay Reclamation, Mumbai-400 020, State of Maharashtra, India The following specification describes the nature of this invention (and the manner in which it is to be performed) TECHNICAL FIELD The present invention relates to a leave-on or rinse-out hair care conditioning or styling composition comprising a silicone quaternary compound and a cationic thickener which provide improved styling benefits. BACKGROUND OF THE INVENTION Most individuals buy and use a hair shampoo for its cleansing properties. In addition to having clean hair, a consumer also desires sufficiently conditioned hair that holds a preset configuration. However, hair shampoos are generally formulated with highly effective anionic surfactants that primarily clean as opposed to condition the hair. Anionic surfactants not only remove the dirt and soil from hair, but also remove sebum naturally present on the surface of hair fibers. Therefore, the desirable cleansing properties of anionic surfactants also can leave hair in a cosmetically unsatisfactory condition. Shampoos also do not detangle wet hair and do not impart residual conditioning benefits to dry hair such as manageability or styleability of hair sets. In general, shampoo compositions containing anionic surfactants, or nonionic surfactants or amphoteric surfactants, leave hair with an undesirable harsh, dull and dry touch, or feel, after the hair is shampooed and then rinsed with water. Furthermore, thoroughly cleansed hair also is extremely difficult to comb, in either the wet or the dry state, because the individual hair fibers tend to snarl, kink, and interlock with each other. In addition, incompletely dried hair, such as hair dried with a towel, has poor brushing properties, and after complete drying, the hair does not set well. The combing or brushing properties of dry hair remain poor, and the hair has undesirable electrostatic properties in a low humidity atmosphere that causes the hair to "fly away" thereby further reducing the brushing properties of the hair. The unsatisfactory combing or brushing properties of hair immediately after shampooing or during trimming treatments after shampooing also causes hair damage such as split ends or hair breakage. In addition the natural luster and resiliency of hair is reduced. The overall unsatisfactory condition of shampooed hair often makes necessary a subsequent post shampoo treatment of the hair with a conditioning composition to improve these undesirable physical characteristics. Conditioning compositions typically are applied separately from the hair shampoo, and usually are rinses, cream-like emulsions or lotions containing a cationlc compound-Therefore, the consumer has traditionally shampooed the hair to cleanse the hair, and followed this with the application of a conditioner composition to improve wet combing. The commonly accepted method has been to shampoo the hair, followed by rinsing the hair, and then applying a conditioner composition, followed by a second rinse. The wet combing problem has been solved by treating shampooed hair with a conditioner composition that coats the hair shaft and causes individual hair fibers to resist tangling and matting because of the conditioner residue retained on the hair shaft. Conventional leave-on or rinse-out hair conditioners rely on fatty alcohols to build viscosity, and on alkyl quaternaries and silicones to provide conditioning. While these conventional leave-on or rinse-out hair conditioners, do condition the hair, the fatty alcohols tend to deposit on the hair surface along with the conditioning agents, thereby weighing down the hair. Therefore, hair that has been conditioned with these conventional leave-on or rinse-out hair conditioners tends to have less body than unconditioned hair. It would be desirable to develop a leave-on or rinse-out hair conditioner composition that does not thereby substantially decrease natural hair body. It would also be desirable for a leave-on or rinse-out hair conditioner to incorporate a water-soluble styling resin,to deliver a hair styling benefit. It would also be desirable to provide such a leave-on or rinse-out' styling conditioner at low cost. Compositions of the present invention have these properties. Publications related to the invention are as follows: U.S. Patent No. 5,679,114 discloses hair treatment compositions for temporarily coloring the hair which contain a polymer and a metal containing pigment. US Patent No.5,034,218 discloses stable conditioning shampoos containing a compatible anionic surfactant/cationic conditioning agent, non-volatile silicone emulsion. US Patent No.5,665, 337 discloses compositions which comprise from about 0.25% to about 70% of a copolymer component comprising from about 1.5% to about 70% of a silicone-grafted adhesive hair styling copolymer having a weight average molecular weight from about 300,000 to about 5,000,000 and from about 30% to about 98.5% of a hydrophobic volatile solvent. US Patent No.4,749,565 discloses cosmetic compositions based on cationic silicone, water-soluble heteropolysaccharide and electrolyte. US Patent No.6,028,041 discloses hair conditioning compositions which include a cationic polymer and an aminated silicone in an aqueous carrier. All reported compositions are formulated with substantial amounts of fatty alcohol. WO 94/01076 describes aqueous hair conditioners containing a combination of cellulose-based cationic polymers and may optionally include a silicone quaternary compound. Significant amounts of fatty alcohols are formulated in all of the relevant examples. Volatile silicones are absent from this disclosure. SUMMARY OF THE INVENTION The present invention relates to a leave-on or rinse-out hair conditioning or styling comprising : a) from 0.1 to 6% of a silicone quaternary compound, b) from 0.25 to 5% of a cationic thickener c) from 0.2 to 6% of a volatile silicon having a viscosity from 0.5 to 10 est (0.0005 to 0.01 Pas); and d) water or a hydroalcoholic solvent; wherein the composition has less than 0.05% fatty alcohol. The present invention also relates to a method for conditioning and styling hair which comprises contacting said hair with an effective amount of a composition of the invention. DETAILED DESCRIPTION OF THE INVENTION Definitions As used herein % means weight % of the total composition, unless otherwise indicated. "Fatty alcohol" means an alcohol of 8 carbons or more. "Substantially lacking in fatty alcohol" means a level of fatty alcohol in the composition that is so low that upon use on the hair, said fatty alcohol does .not cause the hair to lose its natural body. Usually the level of fatty alcohols in the compositions of the invention is less than about 0.2% fatty alcohol. More preferably, compositions of the invention has than 0.1% fatty alcohol or less than 0.05% fatty alcohol. The term "leave-on' refers to a hair care composition that is applied to the hair and not further subjected to a rinsing step. The term "rinse-out" as contrasted with the term "leave-on" is used herein to mean compositions which are used in a context whereby the composition is ultimately rinsed or washed from the hair either after or during the application of the product. Leave-on or rinse-out compositions of the invention may take the form of providing the hair with styling benefits, and in particular allowing the hair to retain a given style for a 6 longer period of time. In this context the word "style" is given its usual meaning in the art, which is the act of creating a style in the hair, often after some initial drying. In any event the act of styling usually requires that the hair retain a given configuration, with individual hair shafts generally retaining their configuration relative to each other. The benefits from compositions of the invention may be derived whether the hair is dried with a hair dryer, or allowed to dry naturally. Traditional hair conditioning compositions rely upon fatty alcohols to build viscosity. However, fatty alcohols tend to deposit on the hair surface along with the conditioning agents resulting in less body than unconditioned hair. The compositions of the invention are substantially free of fatty alcohol and thereby avoid this problem. After treatment with compositions of the invention, hair is left with more of its natural body. Conditioning Compositions The starting materials used in preparing the compositions of the invention are either known or can be prepared according to known methods. Compositions of the invention can be prepared by known methods, or by methods that are analogous to known methods. The hair conditioning compositions of the present invention can be used as either leave-on or rinse-out products. The compositions of the invention are oil-in-water dispersions and/or emulsions. In compositions of the invention, there is a combination of a silicone quaternary compound and a cationic thickener. The ingredients employed in the compositions of the invention are as follows: Silicone Quaternary Compounds Suitable silicone quaternary ammonium compounds that may be employed in the compositions of the invention are those having the general formula: {(R1) (R2) (R3) N+ CH2CH(OH)CH20(CH2)3[Si(R4) (R5)-0-]n-Si(R ) (R )-(CH2)3-0-CH2CH(OH)CH2N (R ) (R ) (R ) } (X )2 wherein R and R may be the same or different and may be independently selected from H, saturated or unsaturated long or short chain alk(en)yl, branched chain alk(en)yl and C5-C8 cyclic ring systems; 2 9 R thru' R may be the same or different and may be independently selected from H, straight or branched chain lower alk(en)yl, and C5-C8 cyclic ring systems; n is a number within the range of about 60 to about 12 0, preferably about 80, and X" is preferably acetate, but may instead be for example halide, organic carboxylate, organic sulphonate or the like. Suitable quaternary silicone polymers of this class are described in EP-A-0 530 974. Preferred silicone quaternary ammonium compounds include cationic silicone derivatives, such as Quaternium-80, having the structureTset forth on volume 1, pages 631 and 632 of the International Cosmetic Ingredient Dictionary, fifth edition, 1993, editor Wenninger et al. Cationic Thickener Compositions of the invention also comprise a cationic thickener. Non-limiting examples of cationic thickeners that can be used in compositions of the invention include cationic acrylates, most preferably Salcare SC 96. Salcare SC 96 is available from Ciba Specialty Chemicals, as a liquid dispersion polymer composition. The composition of Salcare SC 96 is approximately 44% by weight Polyquatemium-37 polymer. Polyquaternium-37 polymer is a water swellable polymer and is also referred to as N,N,N-trimethyl-2{(methyl-1-oxo-2-propenyl)oxy), chloride polymer and which has the chemical structure set forth at page 1145 having the structure set forth on volume 2, page 1145 of the International Cosmetic Ingredient Dictionary, eighth edition, 2 000, editor Wenninger et al. The remainder of the Salcare SC 96 polymer composition is described as comprising a mixture of propylene glycol/dicaprylate/dicaprate 50% propyleneglycol-1 trideceth 6 at 6%. Other cationic thickeners which may be used include Salcare 95 which is dimethylaminoethylmethacrylate homopolymer; SC 10 which is dimethylammonium chloride acrylamide; and SC 60 which is copolymer of acrylamidylpropyltriammonium chloride. Carrier Compositions of the invention also comprise water, preferably, deionized water. The compositions of the invention may also comprise hydroalcoholic solvent. Optional Ingredients Non-volatile Silicone Compounds Other non-volatile silicone quaternary compounds that may be used are silicone compounds that are included in the oil phase of compositions of the invention. The preferred other silicone compounds are polyalkylsiloxanes- such as polydimethylsiloxane, and polymethylphenylsiloxane. Polydimethylsiloxanes, which are also known as dimethicones, are especially preferred. The polyalkylsiloxanes that can be used include, for example, polydimethylsiloxanes. These silicone compounds 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. Polyalkylaryl siloxane fluids can also be used and 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 silicone compounds that can be used also include, for example, a polypropylene oxide modified polydimethylsilbxane, although ethylene oxide or mixtures of ethylene oxide and propylene oxide modified polydimethylsiloxanes can also be used. The ethylene oxide and polypropylene oxide level should be sufficiently low so as not to interfere with the dispersibility characteristics of the silicone. These materials are also known as dimethicone copolyols. Other silicone compounds include amino substituted materials such as suitable alkylamino substituted silicone compounds. An especially preferred amino substituted silicone is the polymer known as trimethylsilylamodimethicone. A preferred polymer of this class is available from Union Carbide under the name "UCAR SILICONE ALE 56." References, disclosingv suitable nonvolatile dispersed silicone compounds include U.S. Patent No. 2,826,551, to Geen; U.S. Patent No. 3,964,500, to Drakoff, issued June 22, 1976; U.S. Patent No. 4,364,837, to Pader; and British Patent No. 849,433, to Woolston. Another nonvolatile dispersed silicone that can be especially useful is a silicone gum. The term "silicone gum", as used herein, means a polyorganosiloxane material having a viscosity at 250 degrees C of greater than or equal to 1,000,000 centistokes. It is recognized that the silicone gums described herein can also have some overlap with the above-disclosed silicone compounds. This overlap is not intended as a limitation on any of these materials. Silicone gums are described in U.S. Patent No. 4,152,416, to Spitzer et al., issued May 1, 1979 and Noll, Walter, Chemistry and Technology of Silicones, New York: Academic Press 1968. Also describing silicone gums are 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 include polydimethylsiloxane, poly(dimethylsiloxane methylvinylsiloxane) copolymer, poly (dimethylsiloxane diphenylsiloxane methylvinylsiloxane) copolymer and mixtures thereof. Also useful are silicone resins, which are highly crosslinked polymeric siloxane systems. The crosslinking is introduced through the incorporation of tri- functional and tetra-functional' silanes with mono-functional silanes or di-functional silanes, or both types of 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 silic6ne material. Silicone materials that have at least about 1.0. oxygen atoms per silicon atom will generally be silicone resins herein. Preferably, the ratio of oxygen to silicon atoms is at least about 1.2 to 1.0. Silanes used in the manufacture of silicone resins include monomethyl-, dimethyl-, trimethyl-, monophenyl-, diphenyl-, methylphenyl-, and monovinyl-, with the methyl substituted silanes being most commonly utilized. General Electric as GE SS4230 and SS4267 offers preferred resins. 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 can be supplied and incorporated into the present compositions in such dissolved form, as will be readily apparent to those skilled in the art. Other useful silicone resins are silicone resin powders such as the material given the CTFA designation polymethylsilsequioxane, which is commercially available as From Toshiba Silicones. The method of manufacturing these silicone compounds, can be found in Encyclopedia of Polymer Science and Engineering, Volume 15, Second Edition, pp. 204-308, John Wiley & Sons, Inc., 1989. Commercially available silicone compounds which are useful herein include Dimethicone with tradename D-13 0, cetyl Dimethicone with tradename DC2502, stearyl Dimethicone with tradename DC2503, emulsified polydimethyl siloxanes with tradenames DC1664 and DC1784, and alkyl grafted copolymer silicone emulsion with tradename DC2-2845; all available from Dow Corning Corporation, and emulsion polymerized Dimethiconol available from Toshiba Silicone as described in GB application 2,303,857. Mixtures of the silicone quaternary compounds described above can also be used in the compositions of the invention. Amino Silicones An especially preferred cationic silicone derivative is that sold under the tradename "Dow Corning 929 (DC 929)" cationic emulsion by DOW CHEMICAL COMPANY, which contains in combination: (1) "amodimethicone," (2) "tallowtrimonium chloride," and (3) "nonoxynol -10." Volatile- Silicones The silicone oil phase of the compositions of the invention can also comprise a volatile silicone oil. By "volatile" is meant that the oil has a boiling point less than about 225°C at 760 mm Hg. Exemplary volatile silicone compounds include, but are not limited to, volatile, low molecular weight polydimethylsiloxane compounds. They can be either a linear or a cyclic polydimethylsiloxane compound having a viscosity from about 0.5 to about 10 est (centistokes). The preferred linear polydimethylsiloxane compounds can have a viscosity range from about 0.5 to lOcst. The preferred volatile polydimethylsiloxanes have a viscosity in the range of about 0.5 to about 6 Cst. The cyclic, volatile, low molecular weight polydimethylsiloxanes, designated in the CTFA Dictionary as cyclomethicones, are optionally used in compositions of the present invention. The cyclic volatile siloxanes which can be D4, D5, or D6, and mixtures thereof); boil at atmospheric pressure at from about 35°C to about 250°C. The polydimethyl cyclosiloxanes having an average of about 4 to about 5 repeating units per molecule are especially preferred. Suitable cyclomethicones are available commercially under the trade names DOW CORNING 244 Fluid, DOW CORNING 245 Fluid, DOW CORNING 344 Fluid and DOW CORNING 345 Fluid from DOW CORNING Corporation, Midland, MI., and SILICONE SF-1173 and SILICONE SF-1202 from General Electric, Waterford, NY. An example of a linear, low molecular weight, volatile polydimethylsiloxane compound is designated in the CTFA Dictionary, as decamethyl.te>trasiloxaiae, available commercially under the trade name DOW CORNING 200 Fluid having a viscosity of 0.5 to 1.5 est. Other linear polydimethylsiloxanes include octamethyltrisiloxane, decamethylpentasiloxane and mixtures thereof which also may be useful in the compositions of the invention. Other volatile silicones useful in compositions of the invention include phenyl pentamethyldisiloxane, phenyl pentaethyldisiloxane, methoxy propylheptamethyldisiloxane, and mixtures thereof. Mixtures of the silicones described above can also be used in the compositions of the invention. Styling Resins When it is desired to produce a composition of the invention that also has styling properties, a water-soluble styling resin can be included in such compositions. Water-soluble styling resins include Copolymer 845, Gafquat 755N, Gafquat H5100, Styleze CC-10 (a quaternized polyacrylate), Celquat L200 and Chitosan PCA. Waxes When it is desired to opacify the compositions of the invention, so that they look like traditional hair conditioners, waxes can be added to said compositions. Such waxes may be selected from the group consisting of paraffin wax, beeswax, microcrystalline wax, ozokerite wax, carnauba wax, and candelilla wax, and mixtures thereof. Mixed hydrocarbon silicone waxes may also be used. Most preferred is paraffin wax.

LEAVE-ON OR RINSE-OUT HAIR CARE CONDITION CO MPOSITIONS CONTAINING SILICONE QUATERNARY COMPOUNDS AND CATIONIC
THICKENERS

HINDUSTAN LEVER LIMITED, a company incorporated under the Indian Companies Act, 1913 having its registered office at Hindustan Lever House, 165/166, Backbay Reclamation, Mumbai-400 020, State of Maharashtra, India
The following specification describes the nature of this invention (and the manner in which it is to be performed)

TECHNICAL FIELD
The present invention relates to a leave-on or rinse-out hair care conditioning or styling composition comprising a silicone quaternary compound and a cationic thickener which provide improved styling benefits.
BACKGROUND OF THE INVENTION
Most individuals buy and use a hair shampoo for its cleansing properties. In addition to having clean hair, a consumer also desires sufficiently conditioned hair that holds a preset configuration. However, hair shampoos are generally formulated with highly effective anionic surfactants that primarily clean as opposed to condition the hair. Anionic surfactants not only remove the dirt and soil from hair, but also remove sebum naturally present on the surface of hair fibers. Therefore, the desirable cleansing properties of anionic surfactants also can leave hair in a cosmetically unsatisfactory condition. Shampoos also do not detangle wet hair and do not impart residual conditioning benefits to dry hair such as manageability or styleability of hair sets.
In general, shampoo compositions containing anionic surfactants, or nonionic surfactants or amphoteric surfactants, leave hair with an undesirable harsh, dull and dry touch, or feel, after the hair is shampooed and then rinsed with water. Furthermore, thoroughly cleansed hair also is extremely difficult to comb, in either the wet or

the dry state, because the individual hair fibers tend to snarl, kink, and interlock with each other. In addition, incompletely dried hair, such as hair dried with a towel, has poor brushing properties, and after complete drying, the hair does not set well. The combing or brushing properties of dry hair remain poor, and the hair has undesirable electrostatic properties in a low humidity atmosphere that causes the hair to "fly away" thereby further reducing the brushing properties of the hair.
The unsatisfactory combing or brushing properties of hair immediately after shampooing or during trimming treatments after shampooing also causes hair damage such as split ends or hair breakage. In addition the natural luster and resiliency of hair is reduced. The overall unsatisfactory condition of shampooed hair often makes necessary a subsequent post shampoo treatment of the hair with a conditioning composition to improve these undesirable physical characteristics. Conditioning compositions typically are applied separately from the hair shampoo, and usually are rinses, cream-like emulsions or lotions containing a cationlc compound-Therefore, the consumer has traditionally shampooed the hair to cleanse the hair, and followed this with the application of a conditioner composition to improve wet combing. The commonly accepted method has been to shampoo the hair, followed by rinsing the hair, and then applying a conditioner composition, followed by a second rinse. The wet combing problem has been solved by treating shampooed hair with a conditioner composition that coats the hair

shaft and causes individual hair fibers to resist tangling and matting because of the conditioner residue retained on the hair shaft.
Conventional leave-on or rinse-out hair conditioners rely on fatty alcohols to build viscosity, and on alkyl quaternaries and silicones to provide conditioning. While these conventional leave-on or rinse-out hair conditioners, do condition the hair, the fatty alcohols tend to deposit on the hair surface along with the conditioning agents, thereby weighing down the hair. Therefore, hair that has been conditioned with these conventional leave-on or rinse-out hair conditioners tends to have less body than unconditioned hair.
It would be desirable to develop a leave-on or rinse-out hair conditioner composition that does not thereby substantially decrease natural hair body. It would also be desirable for a leave-on or rinse-out hair conditioner to incorporate a water-soluble styling resin,to deliver a hair styling benefit. It would also be desirable to provide such a leave-on or rinse-out' styling conditioner at low cost. Compositions of the present invention have these properties.

SUMMARY OF THE INVENTION
The present invention relates to a leave-on or rinse-out hair conditioning or styling comprising :
a) from 0.1 to 6% of a silicone quaternary compound,
b) from 0.25 to 5% of a cationic thickener
c) from 0.2 to 6% of a volatile silicon having a viscosity from 0.5 to 10 est (0.0005 to 0.01 Pas); and
d) water or a hydroalcoholic solvent;
wherein the composition has less than 0.05% fatty alcohol.
The present invention also relates to a method for conditioning and styling hair which comprises contacting said hair with an effective amount of a composition of the invention.

DETAILED DESCRIPTION OF THE INVENTION
Definitions
As used herein % means weight % of the total composition, unless otherwise indicated.
"Fatty alcohol" means an alcohol of 8 carbons or more.
"Substantially lacking in fatty alcohol" means a level of fatty alcohol in the composition that is so low that upon use on the hair, said fatty alcohol does .not cause the hair to lose its natural body. Usually the level of fatty alcohols in the compositions of the invention is less than about 0.2% fatty alcohol. More preferably, compositions of the invention has than 0.1% fatty alcohol or less than 0.05% fatty alcohol.
The term "leave-on' refers to a hair care composition that is applied to the hair and not further subjected to a rinsing step.
The term "rinse-out" as contrasted with the term "leave-on" is used herein to mean compositions which are used in a context whereby the composition is ultimately rinsed or washed from the hair either after or during the application of the product.
Leave-on or rinse-out compositions of the invention may take the form of providing the hair with styling benefits, and in particular allowing the hair to retain a given style for a
6

longer period of time. In this context the word "style" is given its usual meaning in the art, which is the act of creating a style in the hair, often after some initial drying. In any event the act of styling usually requires that the hair retain a given configuration, with individual hair shafts generally retaining their configuration relative to each other.
The benefits from compositions of the invention may be derived whether the hair is dried with a hair dryer, or allowed to dry naturally.
Traditional hair conditioning compositions rely upon fatty alcohols to build viscosity. However, fatty alcohols tend to deposit on the hair surface along with the conditioning agents resulting in less body than unconditioned hair. The compositions of the invention are substantially free of fatty alcohol and thereby avoid this problem. After treatment with compositions of the invention, hair is left with more of its natural body.
Conditioning Compositions
The starting materials used in preparing the compositions of the invention are either known or can be prepared according to known methods. Compositions of the invention can be prepared by known methods, or by methods that are analogous to known methods.
The hair conditioning compositions of the present invention can be used as either leave-on or rinse-out products.

The compositions of the invention are oil-in-water dispersions and/or emulsions. In compositions of the invention, there is a combination of a silicone quaternary compound and a cationic thickener.
The ingredients employed in the compositions of the invention are as follows:
Silicone Quaternary Compounds
Suitable silicone quaternary ammonium compounds that may be employed in the compositions of the invention are those having the general formula:
{(R1) (R2) (R3) N+ CH2CH(OH)CH20(CH2)3[Si(R4) (R5)-0-]n-Si(R ) (R )-(CH2)3-0-CH2CH(OH)CH2N (R ) (R ) (R ) } (X )2
wherein R and R may be the same or different and may be independently selected from H, saturated or unsaturated long or short chain alk(en)yl, branched chain alk(en)yl and C5-C8 cyclic ring systems;
2 9
R thru' R may be the same or different and may be
independently selected from H, straight or branched chain lower alk(en)yl, and C5-C8 cyclic ring systems;
n is a number within the range of about 60 to about 12 0, preferably about 80, and

X" is preferably acetate, but may instead be for example halide, organic carboxylate, organic sulphonate or the like. Suitable quaternary silicone polymers of this class are described in EP-A-0 530 974.
Preferred silicone quaternary ammonium compounds include cationic silicone derivatives, such as Quaternium-80, having the structureTset forth on volume 1, pages 631 and 632 of the International Cosmetic Ingredient Dictionary, fifth edition, 1993, editor Wenninger et al.
Cationic Thickener
Compositions of the invention also comprise a cationic thickener. Non-limiting examples of cationic thickeners that can be used in compositions of the invention include cationic acrylates, most preferably Salcare SC 96. Salcare SC 96 is available from Ciba Specialty Chemicals, as a liquid dispersion polymer composition.
The composition of Salcare SC 96 is approximately 44% by weight Polyquatemium-37 polymer. Polyquaternium-37 polymer is a water swellable polymer and is also referred to as N,N,N-trimethyl-2{(methyl-1-oxo-2-propenyl)oxy), chloride polymer and which has the chemical structure set forth at page 1145 having the structure set forth on volume 2, page 1145 of the International Cosmetic Ingredient Dictionary, eighth edition, 2 000, editor Wenninger et al.
The remainder of the Salcare SC 96 polymer composition is described as comprising a mixture of propylene

glycol/dicaprylate/dicaprate 50% propyleneglycol-1 trideceth 6 at 6%.
Other cationic thickeners which may be used include Salcare 95 which is dimethylaminoethylmethacrylate homopolymer; SC 10 which is dimethylammonium chloride acrylamide; and SC 60 which is copolymer of acrylamidylpropyltriammonium chloride.
Carrier
Compositions of the invention also comprise water, preferably, deionized water. The compositions of the invention may also comprise hydroalcoholic solvent.
Optional Ingredients
Non-volatile Silicone Compounds
Other non-volatile silicone quaternary compounds that may be used are silicone compounds that are included in the oil phase of compositions of the invention. The preferred other silicone compounds are polyalkylsiloxanes- such as polydimethylsiloxane, and polymethylphenylsiloxane. Polydimethylsiloxanes, which are also known as dimethicones, are especially preferred. The polyalkylsiloxanes that can be used include, for example, polydimethylsiloxanes. These silicone compounds 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.

Polyalkylaryl siloxane fluids can also be used and 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 silicone compounds that can be used also include, for example, a polypropylene oxide modified
polydimethylsilbxane, although ethylene oxide or mixtures of ethylene oxide and propylene oxide modified polydimethylsiloxanes can also be used. The ethylene oxide and polypropylene oxide level should be sufficiently low so as not to interfere with the dispersibility characteristics of the silicone. These materials are also known as dimethicone copolyols.
Other silicone compounds include amino substituted materials such as suitable alkylamino substituted silicone compounds. An especially preferred amino substituted silicone is the polymer known as trimethylsilylamodimethicone. A preferred polymer of this class is available from Union Carbide under the name "UCAR SILICONE ALE 56." References, disclosingv suitable nonvolatile dispersed silicone compounds include U.S. Patent No. 2,826,551, to Geen; U.S. Patent No. 3,964,500, to Drakoff, issued June 22, 1976; U.S. Patent No. 4,364,837, to Pader; and British Patent No. 849,433, to Woolston.
Another nonvolatile dispersed silicone that can be especially useful is a silicone gum. The term "silicone gum", as used herein, means a polyorganosiloxane material

having a viscosity at 250 degrees C of greater than or equal to 1,000,000 centistokes. It is recognized that the silicone gums described herein can also have some overlap with the above-disclosed silicone compounds. This overlap is not intended as a limitation on any of these materials. Silicone gums are described in U.S. Patent No. 4,152,416, to Spitzer et al., issued May 1, 1979 and Noll, Walter, Chemistry and Technology of Silicones, New York: Academic Press 1968. Also describing silicone gums are 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 include polydimethylsiloxane, poly(dimethylsiloxane methylvinylsiloxane) copolymer, poly (dimethylsiloxane diphenylsiloxane methylvinylsiloxane) copolymer and mixtures thereof.
Also useful are silicone resins, which are highly crosslinked polymeric siloxane systems. The crosslinking is introduced through the incorporation of tri- functional and tetra-functional' silanes with mono-functional silanes or di-functional silanes, or both types of 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 silic6ne material. Silicone materials that have at least about 1.0. oxygen atoms per silicon atom will generally be silicone resins herein. Preferably, the ratio of oxygen to silicon atoms is at least about 1.2 to 1.0. Silanes used in the manufacture of silicone resins include monomethyl-, dimethyl-, trimethyl-, monophenyl-, diphenyl-, methylphenyl-, and monovinyl-, with the methyl substituted silanes being most commonly utilized. General Electric as GE SS4230 and SS4267 offers preferred resins. 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 can be supplied and incorporated into the present compositions in such dissolved form, as will be readily apparent to those skilled in the art.
Other useful silicone resins are silicone resin powders such as the material given the CTFA designation
polymethylsilsequioxane, which is commercially available as From Toshiba Silicones.
The method of manufacturing these silicone compounds, can be found in Encyclopedia of Polymer Science and Engineering, Volume 15, Second Edition, pp. 204-308, John Wiley & Sons, Inc., 1989.
Commercially available silicone compounds which are useful herein include Dimethicone with tradename D-13 0, cetyl Dimethicone with tradename DC2502, stearyl Dimethicone with

tradename DC2503, emulsified polydimethyl siloxanes with tradenames DC1664 and DC1784, and alkyl grafted copolymer silicone emulsion with tradename DC2-2845; all available from Dow Corning Corporation, and emulsion polymerized Dimethiconol available from Toshiba Silicone as described in GB application 2,303,857.
Mixtures of the silicone quaternary compounds described above can also be used in the compositions of the invention.

(1) "amodimethicone,"
(2) "tallowtrimonium chloride," and
(3) "nonoxynol -10."
Volatile- Silicones
The silicone oil phase of the compositions of the invention can also comprise a volatile silicone oil. By "volatile" is meant that the oil has a boiling point less than about 225°C at 760 mm Hg. Exemplary volatile silicone compounds include, but are not limited to, volatile, low molecular weight polydimethylsiloxane compounds. They can be either a linear or a cyclic polydimethylsiloxane compound having a viscosity from about 0.5 to about 10 est (centistokes). The

preferred linear polydimethylsiloxane compounds can have a viscosity range from about 0.5 to lOcst. The preferred volatile polydimethylsiloxanes have a viscosity in the range of about 0.5 to about 6 Cst.
The cyclic, volatile, low molecular weight
polydimethylsiloxanes, designated in the CTFA Dictionary as cyclomethicones, are optionally used in compositions of the present invention. The cyclic volatile siloxanes which can be D4, D5, or D6, and mixtures thereof); boil at atmospheric pressure at from about 35°C to about 250°C. The polydimethyl cyclosiloxanes having an average of about 4 to about 5 repeating units per molecule are especially preferred. Suitable cyclomethicones are available commercially under the trade names DOW CORNING 244 Fluid, DOW CORNING 245 Fluid, DOW CORNING 344 Fluid and DOW CORNING 345 Fluid from DOW CORNING Corporation, Midland, MI., and SILICONE SF-1173 and SILICONE SF-1202 from General Electric, Waterford, NY.
An example of a linear, low molecular weight, volatile polydimethylsiloxane compound is designated in the CTFA Dictionary, as decamethyl.te>trasiloxaiae, available commercially under the trade name DOW CORNING 200 Fluid having a viscosity of 0.5 to 1.5 est. Other linear polydimethylsiloxanes include octamethyltrisiloxane, decamethylpentasiloxane and mixtures thereof which also may be useful in the compositions of the invention.
Other volatile silicones useful in compositions of the invention include phenyl pentamethyldisiloxane, phenyl

pentaethyldisiloxane, methoxy propylheptamethyldisiloxane, and mixtures thereof.

Method Of Using Compositions Of The Invention
The invention also relates to a method for styling and/or conditioning hair (without decreasing natural hair body) which comprises contacting said hair with an effective amount of a composition of the invention.
Typically, a rinse-out composition of the invention is worked into wet hair (immediately after a shampoo and rinse) usually with the fingers,- the composition may then be rinsed off, then the hair is combed or brushed. The hair is then dried with a towel or a blow dryer. Alternatively, a composition of the invention may be applied to dry hair simultaneously with the application of water. Alternatively, compositions of the invention may be applied to dry hair and then afterwards additional water may be applied to the hair in a rinsing step. These rinse-out compositions of the invention supply a conditioning benefit to the hair.

Compositions of the invention can also be leave-on conditioners. Such compositions are typically applied with the fingers to wet hairs, or to dry hair; or to dry hair that is subsequently wetted followed by working the hair with a comb or a brush. The composition is then left in the hair and the hair may dried with a towel or a blow dryer. These leave-on compositions of the invention supply a conditioning benefit to the hair. Where these leave-on compositions of the invention may also contain a styling agent, said compositions will also supply a styling benefit to the hair.
The following specific compositions of the invention were made. The examples that follow are intended to illustrate the invention without in any way being limiting in nature.
