Abstract:
An elastomer improves the feel of inorganic powder on the skin. An emulsion cosmetic is characterized by containing: (A) 0.5-20 mass % of an inorganic powder having an elastomer coating layer containing (a1) and (a2); and (B) 20-80 mass % of an oil component. The elastomer is characterized by comprising: (a1) a silicone polymer having an amino group; and (a2) a carboxyl group-containing silicone polymer or a carboxyl group-containing acrylic polymer, wherein the molar ratio of the amino group to the carboxyl group, Y/X is in the range of 0.1-1.2 (Y is the molar amount of the carboxyl group contained in the component (a2), and X is the molar amount of the amino group contained in the component (a1)).
