<p>The present invention refers to a coated cosmetic powder, preferable for coloured cosmetic products, in particular coated with certain siloxane resin polymers, and also refers to a cosmetic composition which contains said coated cosmetic powder. <??>The cosmetic powder is constituted by a powder phase coated with silsesquioxane homopolymers and/or copolymers having an average siloxane unit of the general formula R<1>nSiO(4-n)/2, where each R<1> is independently chosen between a hydrogen atom and a monovalent hydrocarbon group comprising 1 to 10 carbon atoms, wherein more than 80 mole % of R<1> are hydrocarbon groups having from 3 to 10 carbon atoms, n is a value from 1.0 to 1.4, more than 60 mole % of the copolymer comprises R<1>SiO3/2 units, and having a hydroxyl or alkoxy content from 0.2 to 10% by weight.</p> |
