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.

In this work, titanium phosphates were prepared by hydrothermal processes. Then they were treated with ultrasound as a novel white pigment for cosmetics. Their chemical composition, powder properties, photocatalytic activity, colour phase, and smoothness were studied. The obtained materials had a higher Ti/P ratio than that used in preparation conditions because of the formation of titanium oxide and hydroxide. Samples showed homogenized spherical particles by ultrasonic treatment. These titanium phosphates had less photocatalytic activity to protect the sebum on the skin. The obtained materials in hydrothermal process and their thermal products at 100 C showed high reflectance at the range of visible light.

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 sunlight. In this work, titanium phosphates were prepared with additives (urea, sodium lactate, and glycerin) as a novel white pigment. Their chemical composition, powder properties, photo catalytic activity, moisture retention, and smoothness were studied. These white pigments had little photo catalytic activity. The addition of sodium lactate and glycerin improved the moisture retention of titanium phosphates. The slipping resistance of samples became small by the addition of sodium lactate and glycerin.

In this study, titanium phosphates were prepared from titanium chloride and phosphoric acid, sodium pyrophosphate and sodium triphosphate solutions with water retention compounds in hydrothermal process as a novel white pigment for cosmetics. Their chemical composition, powder properties, photo catalytic activity, water retention and smoothness were studied. The addition of glycerin in the preparation from sodium pyrophosphate has the useful method to obtain homogenized spherical particles of titanium phosphate pigments for the cosmetics. These titanium phosphates had less photo catalytic activity to protect the sebum on the skin.

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 of a normal distribution at 2 µm by the hydrothermal treatment for 4 and 8 hours. The slipping resistance of samples became small by the hydrothermal treatment.
