Abstract
A water-in-oil type emulsion cosmetic composition comprising a mixed powder of (A) an organopolysiloxane elastomer spherical powder having an average particle size of 2.0 to 5.0 .mu.m and a particle size distribution of 1 to 15 .mu.m and (B) a hydrophobic silica powder having an average particle size of not more than 0.2 .mu.m, wherein the weight ratio of (A) to (B) is 1:0.1 to 1:5, (C) an oil phase or (C') an oil phase containing at least 30% by weight, based upon the total oil phase component, of silicone oil, (D) an emulsifying agent having an HLB value of not more than 7, and (E) water, and, optionally, (F) a metallic soap or (G) an organically modified clay mineral.
