Catalytically active titanium dioxide is conventionally used as a white pigment\nfor cosmetics, but undesirably induces a certain degree of decomposition of sebum on the\nskin on exposure to ultraviolet radiation in sunlight. In this work, titanium phosphates were\nprepared as a novel white pigment for cosmetics using titanium sulfate and phosphoric acid\nat various temperatures, with/without ultrasonic treatment. The chemical composition,\npowder properties, photo catalytic activity, color phase, moisture retention, and smoothness\nof the phosphates were evaluated. These titanium phosphates had less photo catalytic\nactivity than titanium dioxide, which should be beneficial for protecting sebum on the skin.\nSamples prepared with ultrasonic treatment had lower visible light absorption than those\nnot subjected to ultra sonication. The sample prepared at 40 �°C with ultrasonic treatment\nhad higher moisture retention capacity than those prepared under other conditions. Samples\nprepared at 40 �°C had lower slipping resistance than samples prepared at 7 �°C.
