[摘要]：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 degrees C showed high reflectance at the range of visible light. |
