Titanium dioxide is an inorganic substance with chemical formula of TiO2. It is a white solid or powdered amphoteric oxide with molecular weight of 79.9. It has non-toxic, the best opacity, the best whiteness and brightness. It is considered to be a white pigment with the best performance in the world. Titanium dioxide has strong adhesion and is not easy to change chemically. It is always snow-white. Widely used in coatings, plastics, papermaking, printing ink, chemical fiber, rubber, cosmetics and other industries. It has a high melting point and is also used to make refractory glass, glaze, enamel, clay, high temperature resistant experimental utensils, etc.
At the same time, titanium dioxide has a good UV masking effect. It is often added into textile fibers as a sunscreen, and ultra-fine titanium dioxide powder is also added into sunscreen cream to make sunscreen cosmetics.
