PROBLEM TO BE SOLVED: To provide polycaproamide resin composite microparticles of which the particle diameters are uniform and the oil absorption is high and which, when used as a raw material of a cosmetic, exhibits an improved contact sensation. SOLUTION: The composite microparticles comprises microparticles consisting of a polycaproamide resin of which the surface is covered with microparticles other than those of a polycaproamide resin. The average particle diameter of the composite microparticles is 5-20μm, and the oil absorption of it is 70-200 mL/100 g. COPYRIGHT: (C)2008,JPO&INPIT
