As a white pigment, titanium oxide is used for cosmetic application. This
oxide is well known to have the photo catalytic activity. Therefore, a certain
degree of sebum on the skin is decomposed by the ultraviolet radiation in
sunlight. In this work, titanium phosphates were prepared with titanium
chloride and sodium triphosphate in hydrothermal process as a novel white
pigment. Their chemical composition, powder properties, photo catalytic
activity, color phase, and smoothness were studied. The obtained phosphates had
little photo catalytic activity. The particle size of phosphate pigments
consisted a normal distribution at 2 ¦Ìm by the hydrothermal treatment for 4 and
8 hours. The slipping resistance of samples became small by the hydrothermal
treatment.
