Composition containing an unstable active agent in an oxidizing medium and uses thereof, especially cosmetic uses

摘要

The invention relates to a composition containing, in a physiologically acceptable medium, an unstable active agent in an oxidizing medium and an oil phase comprising cross-linked elastomer solid organopolysiloxane particles consisting of at least one oxyalkylene group and oxyethylene in particular. The unstable active agent in an oxidizing medium is stabilized in the inventive composition. The invention also relates to the use of cross-linked elastomer solid organopolysiloxane particles having an oxyalkylene group for the stabilization of an unstable active agent in an oxidizing medium. The unstable active agent can be vitamin C, vitamin A and/or carotenoids. The composition can be anhydrous or take the form of an emulsion. It is particularly suitable for use in cosmetics. It is soft and fresh when applied, spreads easily, is not sticky and does not make the skin or lips dry.
