Titanium Dioxide occurs as a white, amorphous powder. It is produced by either the sulfate or the chloride process, and processing conditions determine the form, either anatase or rutile, of the final product.
Titanium dioxide can be used to color cosmetics, pharmaceutical products, pet foods and foods including confectionery goods, bakery products, dairy products, cheeses, icings and decorations, frozen desserts, non-dairy creamers, and dried soup.
Titanium dioxide (INS No 171) is a food additive that is included in Table 3 of the General Standard of Food Additives (GSFA), and as such may be used in specified foods under the conditions of good manufacturing practices (GMP) as outlined in the Preamble of the Codex GSFA.
