摘要： A process of preparing a silicone rubber suspension is provided. The process comprises the following steps: 1) preparing an emulsion, the emulsion comprising: a) 100 parts by mass of an organosiloxane with a viscosity between 20 mPa·s and 1,000 mPa·s at 25° C., and having at least two silicon atom-bonded hydroxyl groups in a molecule; b) 3.0 to 10.0 parts by mass of an organoalkoxysilane or a partial hydrolysate thereof; c) 2.0 to 10.0 parts by mass of an alkyl silicate; d) 0.001 to 1.5 parts by mass of a surfactant; and e) 50 to 200 parts by mass of water; and 2) mixing the emulsion with: f) a condensation reaction catalyst; g) 1.0 to 30.0 parts by mass of a surfactant; and h) 0 to 10 parts by mass of water.

摘要： A method to produce a hydrosilylation reaction-crosslinkable silicone rubber powder includes washing the hydrosilylation reaction-crosslinkable silicone rubber powder using an aqueous solution. The aqueous solution can be heated to a temperature of 30° C. to 99° C. The aqueous solution contains at least one type of surfactant. The hydrosilylation reaction-crosslinkable silicone rubber powder produced via the method has a platinum metal content ≦3.5 ppm by mass. The hydrosilylation reaction-crosslinkable silicone rubber powder can be used for various applications, including use in a cosmetic composition, which can also include a cosmetic raw material.
