Sunscreen compositions comprising mineral oxides having hydrophobic coatings and glycoside-substituted polydimethylsiloxanes

   
   

Stable, topically applicable cosmetic/dermatological compositions, notably W/O emulsions, well suited for the UV-photoprotection of the skin, lips and/or the hair, and/or for the makeup of the skin and/or the lips, contain a thus effective amount of at least one mineral oxide having a hydrophobic coating thereon, e.g., coated particulates of an oxide of titanium and/or zinc, and, as a stabilizing agent therefor, a thus effective amount of at least one oxyalkylenated polydimethylsiloxane bearing at least one glycoside residue substituent, formulated into a physiologically acceptable medium therefor.

As composições estáveis, tòpica aplicáveis de cosmetic/dermatological, notàvelmente SEM emulsions, poço servido para o uV-photoprotection-photoprotection da pele, os bordos e/ou o cabelo, e/ou para a composição da pele e/ou os bordos, contêm uma quantidade assim eficaz ao menos de um óxido mineral que tem um revestimento hydrophobic thereon, por exemplo, os particulates revestidos de um óxido do titânio e/ou o zinco, e, como um agente estabilizando-se therefor, uma quantidade assim eficaz ao menos de um oxyalkylenated o rolamento do polydimethylsiloxane ao menos um substituent do resíduo do glycoside, formulado em um meio physiologically aceitável therefor.
