Makeup or care composition comprising an at least partially crosslinked elastomeric solid organopolysiloxane

Abstract

A transfer-resistant, mattifying composition comprising, as a thickener, particles of an at least partially crosslinked elastomeric solid organopolysiloxane in suspension in an aqueous phase. The composition is more particularly a composition for caring for or making up the lips, or a foundation composition for making up both the human face and the human body.
