Claim:
1. A process for producing silicone (meth)acrylate particles, said process comprising: a) producing an emulsion of an aqueous phase and an organic phase, wherein the organic phase has at least one radical initiator and at least one siloxane having at least one (meth)acrylate group of formula (I) b) fully polymerizing the inner phase of the emulsion in the presence of a radical initiator which is more soluble in the organic phase than in the aqueous phase, wherein the at least one siloxane is a compound of formula (II): wherein R R R R′ is independently selected from groups according to formula (I); a=9 to 250; b=0 to 20; c=0 to 20; and with the proviso that, per siloxane of formula (II), if c=0, at least one radical R
