  • Publication number: 20130310530
    Abstract: The present invention relates to cosmetic compositions comprising, as solid particles, silicone methacrylate particles which are obtainable by the steps a) producing an emulsion of water and an organic phase, where the organic phase comprises specifically organopolysiloxanes modified in the terminal and/or lateral position with methacrylate groups, or mixtures thereof, with the addition of at least one emulsifier and optionally one or more coemulsifiers, where the organic phase forms the internal phase of the emulsion, and fully polymerizing the internal phase in the presence of a radical initiator, which is added to the external phase (aqueous phase) in a concentration of from 0.1 to 40% by weight based on the internal phase, and also to corresponding cosmetic compositions.
