Abstract
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.
