Titanium dioxide (E171, Cl white 6) is a white, opaque mineral occurring naturally in three main forms rutile, anatase, and brookite. More than 4 million tons of titanium dioxide are produced per year and it is widely used for industrial applications (paints, inks, plastics, textiles) and in small amounts as a food colorant. ° "° Production and properties — Titanium oxide is mainly produced from ilmenite, a titaniferous ore (FeTiOj). Rutile and anatase are relatively pure titanium dioxide (Ti02) forms. Titanium oxide pigment is produced via chloride or sulfate processes via the treatment of the titanium oxide ore with chlorine gas or sulfuric acid, followed by a series of purification steps. High-purity anatase is preferred for utilization in the food industry. It may be coated with small amounts of alumina or silica to improve technological properties. 

Doping the crystal lattice and coating the surface with metal oxides or hydroxides has reduced the photocatalytic polymer decomposition caused by titanium dioxide to such an extent that all stability requirements can be met. Since anatase is generally more photoactive than rutile, aftertreated and/or lattice-stabilized rutile pigments are preferred for exterior applications (exposure to sunlight).
