Synthesis and pigmental properties of titanium phosphates with the addition of urea

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 is decomposed by the ultraviolet radiation in the sunlight. In this work, titanium phosphates were prepared as a novel white pigment. Their chemical composition, powder properties, photo catalytic activity, moisture retention and smooth were studied with the addition of urea. These white pigments had little photo catalytic activity. The addition of urea improved the moisture retention of titanium phosphates. The slipping resistance of samples became small by heating, on the other hand, the roughness of samples became small by the addition of urea.
