COSMETIC SUMMARY, METALLOXIDE DEPARTMENTS PROTECTED WITH OCEATED HYDROPHOBIC ACID, AND METALLOXIDES PROTECTED WITH OCEATED HYDROPHOBIC ACID, AND THEIR MANUFACTURING PROCEDURES.

摘要

The invention relates to (1) a cosmetic material comprising silica-coated metal oxide particles further surface-treated with a hydrophobicizing agent, and (2) metal oxide particles having a specified infrared absorption spectrum intensity ratio and refractive index which are further treated with a hydrophobicizing agent, and to a process for their production. The invention further relates to a silica-coated metal oxide sol which gives such particles, and to a process for its production. The invention can give ultraviolet-screening cosmetic materials with an excellent transparent feel, wherein the particles are satisfactorily dispersed.
