Description: ANHYDROUS SELF-HEATING COSMETIC COMPOSITIONS , ESPECIALLY ANHYDROUS HAIR CONDITIONING 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 cosmetic 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 quickly agglomerate by presence of water, even small amount of water, and form larger clods which cause uncomfortable gritty feel to the skin and /or hair. Agglomerations may form before and/or during applying the compositions containing inorganic heat generating agents on the skin and/or hair, and may also form during storage. 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 reducing gritty feel to the hair, hair scalp, and/or hands. 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) an inorganic heat generating agent which generates a heat by mixing with water; and (b) a polyoxyalkylene derivative. In one preferred embodiment, the anhydrous cosmetic composition (Composition A) comprises: (a) an inorganic heat generating agent which generates a heat by mixing with water; (b) a polyoxyalkylene derivative comprising a polyoxyethylene/polyoxypropylene copolymer; and (c) an inert carrier. In another preferred embodiment, the anhydrous cosmetic composition (Composition B) comprises: (a) an inorganic heat generating agent which generates a heat by mixing with water; and (b) a polyoxyalkylene derivative comprising a polyoxyethylene glyceryl ester. 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 reducing gritty feel to the skin and/or hair. 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; polyoxyalkylene derivatives can help the dispersion of inorganic heat generating agents in inert carriers, thus, prevent the agglomeration of inorganic heat generating agents which causes gritty feel to the skin and/or hair. It is also believed that; some of the polyoxyalkylene derivatives can provide slippery feel which eases gritty feel caused by inorganic heat generating agents.
