SOLUTION: The white composite powder exhibiting no pearl gloss comprises, as a matrix, anα-alumina plate-like particle having an average particle size of 0.5-20μm, an average thickness of 0.03-0.35μm and an aspect ratio (average particle size/average thickness) of 15-50 and, adhering on the surface thereof, 30-50 mass% (based on the white composite powder) of titanium dioxide. The cosmetic incorporated with the white composite powder exhibiting no pearl gloss, particularly a makeup cosmetic, is provided. COPYRIGHT: (C)2008,JPO&INPIT
