Abstract:
PROBLEM TO BE SOLVED: To obtain a cosmetic containing colored zinc oxide doped with a metal oxide. SOLUTION: This cosmetic contains doped zinc oxide bringing about a specially brilliant colored pigment. The doped zinc oxide is obtained by reacting zinc oxide, zinc carbonate, zinc hydroxide and/or zinc hydroxycarbonate with a sufficient amount of formic acid and/or oxalic acid in the presence of water, an oxide, a carbonate, a hydroxide, a hydroxycarbonate, an oxalate or a formate of a doping metal so as to change zinc oxide, etc., into zinc formate or zinc oxalate, processing the formate or oxalate into a paste, drying, grinding and calcining the ground in an inert gas atmosphere at 700-1,100 deg.C. A bivalent oxide of Ca, Fe, Mn or Mg is suitable as a metal oxide capable of doping zinc oxide. When the doped zinc oxide is used, an inorganic pigment usable as a coloring pigment on the one hand and an ultraviolet light absorber on the other can be produced.
Abstract:
