    摘要: The use of oxazolidinone derivatives in a composition for topical application, especially a cosmetic or dermatological composition, in particular as anti-penetrating agents. These derivatives make it possible especially to prevent the penetration of active agents which are compatible with the skin, the hair and/or mucous membranes, and thus to reduce, or even eliminate altogether, the side effects of these active agents without decreasing their efficacy. Thus, the cosmetic or dermatological compositions containing such active agents make it possible to soften the skin, mucous membranes and the hair.

    摘要: The invention encompasses compounds corresponding to the formula in which R1 denotes a C1-C31, preferably C9-C25, hydrocarbon-comprising radical, in particular a saturated or unsaturated, linear or branched, C1-C31, preferably C9-C25, alkyl radical which can be substituted by one or more optionally esterified hydroxyls; and OR2 denotes a cholesteryl radical; the said compounds being in the form of a pure enantiomer or in the form of a mixture of isomers. The invention also relates to their process of preparation and to their use, in particular for the treatment and care of the skin, hair, nails and eyelashes, in cosmetics or in dermatology.
