摘要
A non-laminar silicon oxide powder manufactured by a process comprising, a dissolution step wherein a concentration of 0.1-5.0M of a silicate which is in the range of 0SiO2/Y2O2 (Y : alkali metal atom) is dissolved in the presence of a cationic surfactant and the pH is 11 or more, a condensation step wherein the pH is adjusted to 10.5 or less and a rod-like micelle is formed with said cationic surfactant and a silicate is condensed on said rod-like micelle, and a removal step wherein said cationic surfactant is removed from the micelle state condensation which has an outer shell made of the silicate by said condensation. The silicon oxide powder is useful as a carrier for cosmetics, pharmaceutical drugs and perfumes. IMAGE
