    • 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.
    • 本发明涉及在生理学上可接受的介质中含有在氧化介质中的不稳定活性剂和油相的组合物,其特征在于包含由至少一个氧化烯基团和氧化乙烯组成的交联弹性体固体有机聚硅氧烷颗粒。 氧化介质中的不稳定活性剂在本发明组合物中稳定。 本发明还涉及具有氧化烯基的交联弹性体固体有机聚硅氧烷颗粒在氧化介质中稳定不稳定活性剂的用途。 不稳定的活性剂可以是维生素C,维生素A和/或类胡萝卜素。 组合物可以是无水的或呈乳液的形式。 特别适用于化妆品。 使用时柔软新鲜,容易涂抹,不粘,不会使皮肤或嘴唇干燥。
