Nacoful titanium dioxide is a natural white inorganic substance that is non-toxic and odorless, and is therefore widely used in the pharmaceutical, food and cosmetic industries. The pigment is a common colorant used in the food processing industry to improve the appearance of food products by increasing their gloss and whiteness. Since titanium dioxide is non-toxic, it is also being used more frequently in cosmetics. To permanently tint the spice powder white, only 5%–8% of titanium dioxide must be applied. This also increases the spice's slipperiness, adherence, and covering power.
As a food coloring and whitening agent, food-grade titanium dioxide is frequently used in foods that require whitening, such as candy coating, chilled fruit, jelly, chewing gum, preserves, jam and mayonnaise. Additionally, the pigment is used in cosmetic products like foundation, powder, sunscreen, etc.
Titanium dioxide is a very common food additive in life. In general, trace amounts of titanium dioxide are harmless to the human body and have no effect on the body. Titanium dioxide is an acidic amphoteric oxide with very stable chemical properties. It hardly reacts with other elements and compounds at room temperature, is insoluble in water, fats, dilute acids, inorganic acids and bases, and is soluble only in hydrofluoric acid.
