A rubber composition, which forms a vulcanizate having excellent surface properties such as pleasant feeling of touch and slipperiness or lubricity, comprises, in addition to conventional ingredients such as an ethylene-propylene copolymer, organopolysiloxane, reinforcing silica filler, process oil and curing agent, a powder of spherical particles, such as a poly(methyl silsesquioxane) powder, in the form having a particle diameter of 0.1 mu m to 50 mu m in a limited amount. The rubber composition forms a spongy rubber vulcanizate when vulcanized in the presence of a blowing agent which, by virtue of excellent surface properties, is useful as powder puffs for make-up. |
