A process for coating the surface of pigment and filler particles with an oleaginous and cosmetically functional material, characterized in that an aqueous suspension of the pigment or filler is mixed with an emulsion of said oleaginous material to be coated onto the surface of pigment or filler particles, followed by adding a component capable of breaking the emulsion to the thus obtained mixture, whereby the emulsified material coalesces onto the surface of the pigment or filler particles. The thus obtained pigments or fillers exhibit excellent properties when used in cosmetics.

Deposition of cosmetically functional material onto pigments and fillers

Compositions comprising water-in-oil emulsions are disclosed comprising pigment coated with polysiloxane; a silicone phase; a water phase; and a polydiorganosiloxane-polyoxylalkylene copolymeric surfactant.

Cosmetic makeup compositions comprising water-in-oil emulsions

Cosmetic products which do not suffer phase separation comprise a mixture of a cosmetically acceptable wax with dimethylpolysiloxane and either an organosilane or an organically substituted polysiloxane.
