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.
摘要:
The present invention provides homogeneously surface-fluorinated metal oxide particulates, characterized in that a metal oxide particulate such as Ti, Al, Si, Ag, Cu, Fe, Zr, Ce, Mn, Sn, Ge and Ta is surface reacted with fluorine gas while allowing the metal oxide particulate to flow, and also provides a process for manufacturing the metal oxide particulates. The homogeneously surface-fluorinated metal oxide particulates according to the present invention are useful as an additive for a weatherproof coating material, a weatherproof resin or a cosmetic material. Furthermore, according to the process of the present invention, the surface of a metal oxide particulate can be homogeneously fluorinated at any ratio in a very simple and efficient manner. Even when the homogeneously surface-fluorinated titanium oxide is incorporated as a white pigment into a thermoplastic resin in a high concentration, the resin coated substrate can maintain the surface smoothness without causing any partial defect and troubles can be greatly prevented from occurring at the melt extrusion coating for obtaining the resin coated substrate.
