Description: ANHYDROUS COSMETIC COMPOSITIONS TECHNICAL FIELD The present invention relates to an anhydrous cosmetic composition which warms by mixing with water. BACKGROUND A variety of cosmetic products such as hair care products and skin care products have been used to the hair and/or skin. With respect to hair care products, for example, hair shampoo products are used for cleansing the hair by removing excess soil and sebum; hair conditioning products are used for providing various conditioning benefits such as moisturized feel, softness, and static control to the hair; hair styling products are used for setting hair style and/or maintaining hair style; hair color products are used for changing hair color and/or maintaining hair color; and hair growth products are used for encouraging hair growth. The efficacy of cosmetic products such as hair care products and skin care products are changed by various factors, for example, amount of products applied, how long products are applied on the hair, temperatures of products, the way of applying products to the hair, and so on. Thus, it may not be easy to obtain expected efficacy from cosmetic products such as hair care products and skin care products. A variety of approaches have been developed to obtain expected efficacy from hair care products. For example, inorganic salts and/or oxides which generate a heat by mixing with water are contained in anhydrous cosmetic compositions, being expected to improve penetration and deposition of conditioning components to skin and/or hair by its heat generating (described in Japanese Patent Laid-open H11-228332). However, it has been found that; inorganic heat generating agents such as inorganic salts and/or oxides sometimes generate greater heat than expected, thus the compositions warm up to a higher temperature than expected. It has been also found that; inorganic heat generating agents such as inorganic salts and/or oxides generate a heat over only a short period of time, thus, it is difficult to obtain prolonged warming from the compositions. Japanese Patent Laid-open No. H11-228333 discloses a heat generating cosmetics comprising a heat generating agent coated by a silicone type coating agent, for providing mild heat changing and prolonged warming. However, coated heat generating agents are generally more expensive than non-coated heat generating agents. Based on the foregoing, there remains a desire for obtaining enhanced efficacy from cosmetic products such as hair care products and skin care products, i.e., a desire for obtaining improved benefits from cosmetic products. With respect to hair care products, for example, there remains a desire for obtaining improved cleansing benefits from hair shampoo products, and obtaining improved hair conditioning benefits such as moisturized feel, softness, and static control from hair conditioning products, while controlling the temperature to which the composition warms up. There also remains a desire for obtaining prolonged warming from cosmetic products such as hair care products and skin care products. There also remains a desire for providing such cosmetic products which can provide above benefits with minimum cost increase. None of the existing art provides all of the advantages and benefits of the present invention. SUMMARY The present invention is directed to an anhydrous cosmetic composition comprising: (a) a heat generating agent which generates a heat by mixing with water; (b) a phase changing agent; and (c) an inert carrier; wherein the phase changing agent has a melting point of from about 30°C to about 70°C and are dispersed in the inert carrier. These and other features, aspects, and advantages of the present invention will become evident to those skilled in the art from a reading of the present disclosure. The present invention provides anhydrous cosmetic compositions which warm by mixing with water. The compositions of the present invention can provide enhanced efficacy while controlling the temperature which the composition warms to. The compositions of the present invention can also provide prolonged warming from cosmetic products. It is believed that; warming cosmetic compositions such as hair care compositions and skin care compositions can provide enhanced efficacy, i.e., can provide improved benefits. With respect to hair care compositions, for example, it is believed that; warming hair shampoo compositions can provide improved cleansing benefits, warming hair styling compositions can provide improved styling benefits, warming hair conditioning compositions can provide improved hair conditioning benefits due to improved penetration of ingredients, and warming hair color compositions and warming hair growth compositions can also provide improved benefits. With respect to skin care compositions, for example, it is believed that; warming body shampoo compositions can provide improved cleansing benefits, warming face cleansing compositions can provide improved cleansing benefits, warming skin conditioning compositions can provide improved conditioning benefits, and warming shaving compositions can provide improved shaving benefits. It is also believed that; the phase changing agent having a certain melting point of the present invention can absorb a heat from the heat generating agent by changing its phase from solid to liquid, and then, release the heat slowly by changing its phase from liquid to solid. Thus, it is believed that; the phase changing agent can prevent the compositions from warming up to a higher temperature than expected, and provide prolonged warming from the compositions, without using coated heat generating agents.

PHASE CHANGING AGENTS The anhydrous cosmetic compositions of the present invention comprise a phase changing agent dispersed in an inert carrier. It is also believed that; the phase changing agent having a certain melting point of the present invention can absorb a heat from the heat generating agent by changing its phase from solid to liquid, and then, release the heat slowly by changing its phase from liquid to solid. Thus, it is believed that; the phase changing agent can prevent the compositions from warming up to a higher temperature than expected, and provide prolonged warming from the compositions, without using coated heat generating agents.

Cationic Polymer The cationic polymer useful herein is described below. As used herein, the term "polymer" shall include materials whether made by polymerization of one type of monomer or. made by two (i.e., copolymers) or more types of monomers. Preferably, the cationic polymer is a water-soluble cationic polymer. 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. The preferred polymer will be sufficiently soluble to form a substantially clear solution at 0.5% concentration, more preferably at 1.0% concentration. 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.

The cationic charge density is preferably at least about 0.1 meq/gram, more preferably at least about 1.5 meq/gram, even more preferably at least about 1.1 meq/gram, still more preferably at least about 1.2 meq/gram. Cationic charge density of the cationic polymer can be determined according to the Kjeldahl Method. Those skilled in the art will recognize 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., CI, Br, I, or F, preferably CI, Br, or I), sulfate, and methylsulfate. 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 Cosmetic Ingredient Dictionary, 3rd edition, edited by Estrin, Crosley, and Haynes, (The Cosmetic, Toiletry, and Fragrance Association, Inc., Washington, D.C., 1982).

Amine-substituted vinyl monomers can be polymerized in the amine form, and then optionally can be converted to ammonium by a quaternization reaction. Amines can also be similarly quatemized subsequent to formation of the polymer. For example, tertiary amine functionalities can be quatemized by reaction with a salt of the formula R'X wherein R' is a short chain alkyl, preferably a C-| - C7 alkyl, more preferably a C-| - C3 alkyl, and X is an anion which forms a water soluble salt with the quatemized ammonium.

The silicone compounds hereof can include volatile soluble or insoluble, or nonvolatile soluble or insoluble silicone conditioning agents. By soluble what is meant is that the silicone compound is miscible with the carrier of the composition so as to form part of the same phase. By insoluble what is meant is that the silicone forms a separate, discontinuous phase from the carrier, such as in the form of an emulsion or a suspension of droplets of the silicone. The silicone compounds herein may be made by conventional polymerization, or emulsion polymerization. The silicone compounds for use herein will preferably have a viscosity of from about 1 ,000 to about 2,000,000 centistokes at 25°C, more preferably from about 10,000 to about 1 ,800,000, and even more preferably from about 25,000 to about 1 ,500,000. 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, which is incorporated by reference herein in its entirety. Silicone compound of high molecular weight may be made by emulsion polymerization. Silicone compounds useful herein include polyalkyl polyaryl siloxanes, polyalkyleneoxide-modified siloxanes, silicone resins, amino-substituted siloxanes, and mixtures thereof. The silicone compound is preferably selected from the group consisting of polyalkyl polyaryl siloxanes, polyalkyleneoxide- modified siloxanes, silicone resins, and mixtures thereof, and more preferably from one or more polyalkyl polyaryl siloxanes. Polyalkyl polyaryl siloxanes useful here in include those with the following structure (I) wherein R is alkyl or aryl, and x is an integer from about 7 to about 8,000. "A" represents groups which block the ends of the silicone chains. The alkyl or aryl groups substituted on the siloxane chain (R) or at the ends of the siloxane chains (A) can have any structure as long as the resulting silicone remains fluid at room temperature, is dispersible, is neither irritating, toxic nor otherwise harmful when applied to the hair, is compatible with the other components of the composition, is chemically stable under normal use and storage conditions, and is capable of being deposited on and conditions the hair. Suitable A groups include hydroxy, methyl, methoxy, ethoxy, propoxy, and aryloxy. The two R groups on the silicon atom may represent the same group or different groups. Preferably, the two R groups represent the same group. Suitable R groups include methyl, ethyl, propyl, phenyl, methylphenyl and phenylmethyl. The preferred silicone compounds are polydimethylsiloxane, polydiethylsiloxane, and polymethylphenylsiloxane. Polydimethylsiloxane, which is also known as dimethicone, is 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 ViscasilR and SF 96 series, and from Dow Corning in their Dow Corning 200 series. Polymethylphenylsiloxanes, for example, from the General Electric Company as SF 1075 methyl phenyl fluid or from Dow Corning as 556 Cosmetic Grade Fluid, are useful herein. Also preferred, for enhancing the shine characteristics of hair, are highly arylated silicone compounds, such as highly phenylated polyethyl silicone having refractive index of about 1.46 or higher, especially about 1.52 or higher. When these high refractive index silicone compounds are used, they should be mixed with a spreading agent, such as a surfactant or a silicone resin, as described below to decrease the surface tension and enhance the film forming ability of the material. Another polyalkyl polyaryl siloxane that can be especially useful is a silicone gum. The term "silicone gum", as used herein, means a polyorganosiloxane material having a viscosity at 25°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 by Petrarch, and others including 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. All of these described references are incorporated herein by reference in their entirety. 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, polydimethylsiloxane methylvinylsiloxane) copolymer, polydimethylsiloxane diphenylsiloxane methylvinylsiloxane) copolymer and mixtures thereof. Polyalkyleneoxide-modified siloxanes useful herein include, for example, polypropylene oxide modified and polyethylene oxide modified polydimethylsiloxane. The ethylene oxide and polypropylene oxide level should be sufficiently low so as not to interfere with the dispersibility characteristics of the silicone. These material are also known as dimethicone copolyols. Silicone resins, which are highly crosslinked polymeric siloxane systems, are useful herein. The crosslinking is introduced through the incorporation of tri- functional and tetra-functional silanes with mono-functional or di-functional, 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 methylvinylchlorosilanes, 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. Without being bound by theory, it is believed that the silicone resins can enhance deposition of other silicone compounds on the hair and can enhance the glossiness of hair with high refractive index volumes. Other useful silicone resins are silicone resin powders such as the material given the CTFA designation polymethylsilsequioxane, which is commercially available as Tospearl^ from Toshiba Silicones. Silicone resins can conveniently be identified according to a shorthand nomenclature system well known to those skilled in the art as the "MDTQ" nomenclature. Under this system, the silicone is described according to the presence of various siloxane monomer units which make up the silicone. Briefly, the symbol M denotes the mono-functional unit (CH3)3SiO)_5; D denotes the difunctional unit (CH3) 2 SiO; T denotes the trifunctional unit (CH3)SiO 5; and Q denotes the quadri- or tetra-functional unit SiO . 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, phenyl, amino, hydroxyl, 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 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, MQ 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. Amino-substituted siloxanes useful herein include those represented by the following structure (II) wherein R is CH3 or OH, x and y are integers which depend on the molecular weight, the average molecular weight being approximately between 5,000 and 10,000. This polymer is also known as "amodimethicone". Suitable amino-substituted siloxane fluids include those represented by the formula (III) (R1 ) a G 3 -a-Si-(-OSiG 2 ) n -(-OSiG b (R 1 )2-b)m-0-SiG 3 . a (R 1 ) a (III) in which G is chosen from the group consisting of hydrogen, phenyl, OH, C -C8 alkyl and preferably methyl; a denotes 0 or an integer from 1 to 3, and preferably equals 0; b denotes 0 or 1 and preferably equals 1 ; the sum n+m is a number from 1 to 2,000 and preferably from 50 to 150, n being able to denote a number from 0 to 1 ,999 and preferably from 49 to 149 and m being able to denote an integer from 1 to 2,000 and preferably from 1 to 10; R is a monovalent radical of formula CqH 2 qL in which q is an integer from 2 to 8 and L is chosen from the groups -N(R 2 )CH 2 -CH 2 -N(R 2 ) 2 -N(R 2 )2 -N(R 2 ) 3 A " -N(R 2 )CH 2 -CH 2 -NR 2 H 2 A " in which R 2 is chosen from the group consisting of hydrogen, phenyl, benzyl, a saturated hydrocarbon radical, preferably an alkyl radical containing from 1 to 20 carbon atoms, and A " denotes a haiide ion. An especially preferred amino-substituted siloxane corresponding to formula (III) is the polymer known as "trimethylsilylamodimethicone", of formula (IV): Si (CH 3.3 (IV ) In this formula n and m are selected depending on the molecular weight of the compound desired. Other amino-substituted siloxane which can be used are represented by the formula (V): where R^ denotes a monovalent hydrocarbon radical having from 1 to 18 carbon atoms, preferably an alkyl or alkenyl radical such as methyl; R4 denotes a hydrocarbon radical, preferably a Ci - Cιs alkylene radical or a C - Cιs. and more preferably C - Cβ, alkyleneoxy radical; Q " is a haiide ion, preferably chloride; r denotes an average statistical value from 2 to 20, preferably from 2 to 8; s denotes an average statistical value from 20 to 200, and preferably from 20 to 50. A preferred polymer of this class is available from Union Carbide under the name "UCAR SILICONE ALE 56." POLYPROPYLENE GLYCOL The hair conditioning composition of the present invention may contain a polypropylene glycol as a conditioning agent. The polypropylene glycol can be included in the composition at a level by weight of, preferably from about 0.1 % to about 10%, more preferably from about 0.25% to about 6%. Some polypropylene glycol described herein can also be used as the "VISCOSITY MODIFYING AGENT" described above. The polypropylene glycol useful herein may has a weight average molecular weight of preferably from about 200 g/mol to about 100,000 g/mol, more preferably from about 1 ,000 g/mol to about 60,000 g/mol. Without intending to be limited by theory, it is believed that the polypropylene glycol herein deposits onto, or is absorbed into hair to act as a moisturizer buffer, and/or provides one or more other desirable hair conditioning benefits. As used herein, the term "polypropylene glycol" includes single-polypropylene glycol-chain segment polymers, and multi-polypropylene glycol-chain segment polymers. The general structure of branched polymers such as the multi-polypropylene glycol- chain segment polymers herein are described, for example, in "Principles of Polymerization," pp. 17-19, G. Odian, (John Wiley & Sons, Inc., 3 rd ed., 1991). The polypropylene glycol herein are typically polydisperse polymers. The polypropylene glycols useful herein have a polydispersity of from about 1 to about 2.5, preferably from about 1 to about 2, and more preferably from about 1 to about 1.5. As used herein, the term "polydispersity" indicates the degree of the molecular weight distribution of the polymer sample. Specifically, the polydispersity is a ratio, greater than 1 , equal to the weight average molecular weight divided by the number average molecular weight. For a further discussion about polydispersity, see "Principles of Polymerization," pp. 20-24, G. Odian, (John Wiley & Sons, Inc., 3 rd ed., 1991). The polypropylene glycol useful herein may be either water-soluble, water- insoluble, or may have a limited solubility in water, depending upon the degree of polymerization and whether other moieties are attached thereto. The desired solubility of the polypropylene glycol in water will depend in large part upon the form (e.g., leave-on, or rinse-off form) of the hair care composition. The solubility in water of the polypropylene glycol herein may be chosen by the artisan according to a variety of factors. Accordingly, for a leave-on hair care composition, it is preferred that the polypropylene glycol herein be a water- soluble polypropylene glycol. Solubility information is readily available from polypropylene glycol suppliers, such as Sanyo Kasei (Osaka, Japan). However, the present invention may also take the form of a rinse-off hair care composition. Without intending to be limited by theory, it is believed that in such a composition, a water-soluble polypropylene glycol may be too easily washed away before it effectively deposits on hair and provides the desired benefit(s). For such a composition, a less soluble, or even a water-insoluble polypropylene glycol is therefore preferred. Accordingly, for a rinse-off hair care composition, it is preferred that the polypropylene glycol herein has a solubility in water at 25 °C of less than about 1 g/100 g water, more preferably a solubility in water of less than about 0.5 g/100 g water, and even more preferably a solubility in water of less than about 0.1 g/100 g water.
