ANHYDROUS COSMETIC COMPOSITIONS CONTAINING QUATERNARY AMMONIUM COMPOUNDS

TECHNICAL FIELD

The present invention relates to an anhydrous cosmetic composition containing a quaternary ammonium compound.

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.

Japanese Patent Laid-open 2001-181156 discloses an anhydrous hair rinse composition comprising polyols, cationic surfactants, Cι₄-C₃₂ fatty alcohols, and silicones, for improving penetration of treatment components to hair by its warming efficacy. Japanese Patent Laid-open 2001-181156 also discloses that; the cationic surfactants are, for example, stearyl trimethyl ammonium chloride, cetyl trimethyl ammonium chloride, behenyl trimethyl ammonium chloride, and distearyl dimethyl ammonium chloride, etc.

It has been found that; it is still not easy to obtain expected conditioning efficacy, especially conditioning benefits such as softness.

One approach to obtain improved conditioning benefits is to increase the level of conditioning agents such as cationic surfactants such as stearyl trimethyl ammonium chloride, cetyl trimethyl ammonium chloride, behenyl trimethyl ammonium chloride, and distearyl dimethyl ammonium chloride, C₁₄-C₃₂ fatty alcohols, and silicones. However, it may not be easy to obtain expected spreadability from cosmetic compositions containing such increased level of conditioning agents. It also may not be easy to manufacture cosmetic compositions containing such increased level of conditioning 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., there remains a desire for obtaining improved benefits from cosmetic products. There also remains a desire for obtaining improved conditioning benefits such as softness from cosmetic products. There is also a desire for providing cosmetic compositions having improved spreadability on hair and/or skin, and which is easy to manufacture.

None of the existing art provides all of the advantages and benefits of the present invention.

SUMMARY

The present invention is directed to a cosmetic composition comprising:

(a) a quaternary ammonium compound having at least one group selected from the group consisting of an ester group, an amido group, and mixtures thereof; and

(b) an anhydrous carrier.

The compositions of the present invention can provide improved conditioning benefits such as softness. The compositions of the present invention have improved spreadability on hair and/or skin, and are easy to manufacture.

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.
