ABSTRACT:
Disclosed is a creamy or milky skin cosmetic composition which contains an emulsifying agent comprising an 18.alpha.-glycyrrhizin (18.alpha.-glycyrrhizic acid or its sodium, potassium 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 causes no irritation to the skin and hence has great safety for the skin, as contrasted with skin cosmetic compositions using synthetic emulsifiers. Moreover, it exhibits very good emulsion stability and storage stability and presents a very attractive appearance (fine texture and good gloss) owing to the unique effects of the 18.alpha.-glycyrrhizin. In particular, this skin cosmetic composition is characterized in that the difficulties inherent in the use of an emulsifying agent comprising an 18.beta.-glycyrrhizin alone (i.e., the fact that the resulting emulsion is subject to gelation, requires a long time for defoaming, and may undergo a considerable change in viscosity when transferred by the application of a shear stress) are overcome.
