Abstract

La présente invention porte sur des compositions photostables qui offrent une protection contre le rayonnement ultraviolet (UV). L'invention concerne particulièrement les écrans solaires avobenzone, octocrylène et oxybenzone, formant un triplet. Les compositions de la présente invention sont exemptes de diesters ou de polyesters de l'acide naphthalène dicarboxylique et sont aussi substantiellement exemptes de quantités substantielles d'autres écrans solaires et de quantités substantielles d'agents d'optimisation. Les écrans solaires de cette invention peuvent être essentiellement exempts, ou exempts, d'alcool monohydrique inférieur et/ou d'acrylates, de C12-22 alkylmethacrylate copolymer en quantité efficace non cumulative pour gélifier un C1-C4 alcool. Le triplet offre étonnamment et maintient substantiellement la valeur initiale de FPS de la composition de l'écran solaire pendant toute la période d'exposition au rayonnement UV. Les compositions de l'invention sont photostables de telle sorte que chaque écran solaire actif du triplet ne se dégrade pas de façon appréciable. La présente invention donne avec exactitude la valeur de protection contre le rayonnement UV réellement fournie sous le soleil naturel.
