Nanometer Titanium Dioxide is white powder or colorless crystals, easy deliguescence in the air ,easily soluble in water and the solution appears base; insoluble in ethanol and ether. It occurs in nature as rutile, anatase, or brookite crystals. When used as a sunscreen nano titanium dioxide absorbs and scatters light. Rutile is the most common form found in nature, while anatase is more photocatalytic or photoreactive than rutile (i.e., it becomes more chemically reactive—with greater potential to react with such chemicals as oxygen—forming potentially toxic products). Titanium dioxide is a white solid chemical substance used as a pigment in paints, paper, ink, plastic. Also, it is used in cosmetics and sunscreens. It is used to increase the whiteness or opacity of many products.
Titanium Dioxide Nanometer mainly used in Cosmetics and Sunscreen , Plastics, rubber and functional fibres, Coatings, Paint and Printing Inks, Paper making, and also used in metallurgy and aerospace industry. The nanochemical form of titanium dioxide (TiO2)—nanotitanium dioxide—measures from 1 to 100 nanometers wide, depending on the formulation.
