Abstract
A composition comprising, in a physiologically acceptable medium, at least one sapogenin and a solubilizing system comprising: (a) at least one non-emulsifying ester of a fatty acid and/or of a fatty alcohol whose hydrocarbon-based chain contains at least 8 carbon atoms, or a plant oil, and (b) at least one branched fatty alcohol whose hydrocarbon-based chain contains at least 8 carbon atoms and/or at least one lipophilic UV screening agent. The solubilizing system according to the invention makes it possible to dissolve a sufficient amount of sapogenin, without recrystallization, for a period of time which is acceptable for cosmetic or dermatological use.
