COSMETIC PREPARATION, SURFACE-HYDROPHOBIZED SILICA-COATED METAL OXIDE PARTICLES, SOL OF SILICA-COATED METAL OXIDE, AND PROCESSES FOR PRODUCING THESE

摘要

The present invention, (1) silica-coated metal oxide cosmetic preparation containing the surface-treated particles zero hydrophobicity imparting particles, (2) treated with the metal oxide particles having a ratio and the refractive index of a particular infrared absorption spectrum intensity zero hydrophobicity imparting particulate and an invention of a method of manufacturing the same. In another aspect, the present invention also has a silica-coated metal oxide sol of the invention and a manufacturing method for obtaining the particle.; According to the invention, the sense of transparency of the particles are uniformly dispersed can be obtained for the excellent sunscreen cosmetic.
