PURPOSE:To provide the titled pigment which gives cosmetic having an excellent hiding power and an excellent ultraviolelt-screening effect, by coating the surface of an inorg. flat material having a specified average particle size with fine TiO2 particles in an amount which does not give an appearance of iridescent luster by interference. CONSTITUTION:The surface of an inorg. flat material (A) having an average particle size of 0.5-100mum selected from the group consisting of natural mica, synthetic mica and glass flake is coated with fine TiO2 particles (B) in an amount which does not give an appearance of iridescent luster by interference, thus obtaining an ultraviolet screening mineral having a hydrophilic surface. The mineral is treated with a hydrophobic material (C) selected from the group consisting of org. fluorine-contg. compds., higher fatty acids (derivatives), higher fatty alcohols (derivatives) and organosilicon compds. |
