    摘要: The invention relates to a process for improving the stability with respect to UV radiation of a photosensitive sunscreen agent, comprising the incorporation of said screening agent in a material prepared by the sol-gel route from at least one silicon alkoxide and from at least one surfactant. It is also targeted at a photostable material which comprises the combination of a photosensitive sunscreen agent and of a photostabilizing material prepared by the sol-gel route including at least one silicon alkoxide and at least one nonionic surfactant and at a cosmetic and/or dermatological composition comprising, in a cosmetically and/or dermatologically acceptable vehicle, an effective amount of a photostable material. This cosmetic and/or dermatological composition is intended mainly for protecting the skin and/or keratinous substances against ultraviolet radiation.

    摘要: The invention concerns a cosmetic or dermatological composition designed for for forming a film on a keratin substrate, in cross-linked hybrid material. Said composition is of the sol/gel type and is obtained by mixing: (a) at least an organometallic compound; (b) at least a functionalised organic polymer or said polymer precursor, or at least a functionalised silicone polymer or said polymer precursor, the precursor being different from (a); (c) a sufficient amount of water for hydrolysing the organometallic compound: and (d) optionally at least an alcohol; said film being non-reversible.
