Abstract
A dispersible powder including an organopolysiloxane elastomer powder treated with a surface treatment agent. The surface treatment agent is an organopolysiloxane having a polyoxyalkylene group, a weight-average molecular weight of 300 to 300,000, and an HLB of 8 to 18. Thus, an organopolysiloxane elastomer powder has excellent dispersibility and high over-time dispersion stability in an aqueous medium; and a cosmetic can be blended with the powder.
