Abstract Full text About this article

Titanium phosphates were prepared from titanium chloride and sodium pyrophosphate at various pH in hydrothermal process as a novel white pigment for cosmetics. Their chemical composition, powder properties, photo catalytic 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. The samples prepared at pH = 4 had particles smaller than 100 µm. Titanium phosphates had less photo catalytic activity to protect the sebum on the skin. The obtained materials in hydrothermal process and their thermal products at 100 ℃ showed high reflectance in the range of visible light.
