It applies in cosmetics, sunscreens, pharmaceutical tablet coatings and foods — mainly chewing gum and other confectionery products. It has a high refractive index, which contributes to its bright, white color and opacity. While found in nature, it may be synthetically produced, leading to very low contaminant levels compared to the crude source extraction. Titanium dioxide may be coated with alumina or silica to improve its functional properties. 收起 | |

It is is produced through steam activation (charring) of vegetable fibers. It is an insoluble black food coloring used in confectionery products, icing, baked goods and ice cream. European and Canadian authorities approve its use as a colour additive. The United States FDA does not allow its use. 收起 |
