Abstract: The present invention relates to a cosmetic composition comprising core particles in a cosmetically or pharmaceutically acceptable carrier, wherein the core particles comprise a heat-curable coating which is the reaction product of a vinyl-functional silicone polymer, a hydride-functional crosslinker, and a metal catalyst.

Abstract: The present invention relates to a method for forming coated particles, comprising the steps of: agitating a volume of core particles while heating to a constant average temperature of about 40° C. Once particles are generally evenly mixed, with no apparent agglomeration, the vinyl-functional silicone polymer, hydride-functional crosslinker, and metal catalyst are combined in a premix under continuous propeller-mixing. The vinyl-functional silicone polymer, hydride-functional crosslinker, and metal catalyst premix is then siphoned into the main vessel, containing the heated core particles, at rate that ensures no clumping or agglomeration of the particulates. Once even coating has been achieved, the main vessel is heated to an average temperature of about 80° C., then cooled back down to room temperature (about 20° C.-28° C.). The coated material is then passed through a 45 ?m sieve to remove any large particulates that may be present.
