摘要:
Topically applicable photostable sunscreen/photoprotective compositions contain at least one dibenzoylmethane UV-sunscreen and an effective photostabilizing amount therefor of at least one amphiphilic block copolymer which comprises at least one nonionic hydrophilic polymer block and at least one hydrophobic polymer block, formulated into a topically applicable, cosmetically acceptable medium therefor.
摘要:
The use of a composition comprising at least one organometallic compound which may be obtained by partial or total hydrolysis, and partial or total condensation, of at least one metallic precursor, to at least one of protect and strengthen a keratin material.
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.
摘要:
The invention concerns a make-up or coloring method comprising steps which consist in imaging at least one part of the human body to be treated, analysing local characteristics of said part, and applying treatment products of said part based on said local characteristics.
