SYNTHETIC RESIN POROUS PARTICLE COMBINED WITH HYDROXYAPATITE PARTICLE, EXTERNAL PREPARATION, AND COSMETIC

摘要

PROBLEM TO BE SOLVED: To provide porous particles combined with hydroxyapatite, capable of being suitably mixed into a cosmetic, especially, a make-up cosmetic and a skin-care cosmetic.;SOLUTION: The porous particles are synthesized by adding hydroxyapatite particles having a desired particle diameter to a suspension used for the synthesis, when the porous particles are synthesized according to conventional methods, such as a suspension method. The particles thus obtained are mixed into an external preparation or the cosmetic.;COPYRIGHT: (C)2005,JPO&NCIPI
