Clear liquid skin cosmetic compositions

摘要

Disclosed is a clear liquid skin cosmetic composition (e.g., a lotion) in which one or more oily substances (such as oil-soluble perfumes, hormones and the like) are solubilized in water with the aid of a solubilizing agent comprising an 18 alpha -glycyrrhizin (18 alpha -glycyrrhizic acid sodium salt, potassium salt or ammonium salt) that is a novel compound derived from a conventional glycyrrhizin (i.e., any form of 18 beta -glycyrrhizin extracted from licorice root) or a glycyrrhizin composition consisting of an 18 alpha -glycyrrhizin and an 18 beta -glycyrrhizin. This skin cosmetic composition is not irritative to the skin as contrasted with skin cosmetic compositions prepared by using a synthetic surface-active agent as the solubilizing agent, and is not subject to gelation in a slightly acidic to acidic pH range as contrasted with skin cosmetic compositions prepared by using an 18 beta -glycyrrhizin alone as the solubilizing agent. Moreover, this skin cosmetic composition exerts a mild action on the skin without causing irritation thereto, gives an agreeable feeling, and has excellent fluidity, usability and storage stability.
