Although the evidence for general toxic effects was not conclusive, on the basis of the new data and strengthened methods our scientists could not rule out a concern for genotoxicity and consequently they could not establish a safe level for daily intake of TiO₂ as a food additive.

Titanium dioxide, or TiO2, sometimes referred to as E171, is an inorganic, solid substance used in a wide range of consumer goods including cosmetics, paint, plastic and food, according to the American Chemistry Council.

Studies suggest that people are more likely to buy and eat foods that are brighter or more vibrant in color. And titanium dioxide is one way to make that happen. You can find it in food products like candy, coffee creamer, baking and cake decorations, and white sauces.

Description:

① Coatings: The downstream demand structure of domestic and overseas titanium dioxide is similar. Coatings are the largest application fields, accounting for 61% of the consumption. Among the four components of paint products, namely resin, pigments and fillers, solvents and additives, titanium dioxide accounts for 10% to 25% of the total cost, accounting for more than 90% of the total amount of pigments and fillers, and more than 95% of the total amount of white pigments.

The major restraint to the global Lithopone market is the availability of numerous white pigment substitutes. It can be replaced by other inorganic white pigments such as Titanium Dioxide (TiO2) and Sachtolith. Among these substitutes, the introduction of TiO2 has reduced the commercial importance of Lithopone white pigment. Compared to other white pigments, TiO2 has high brightness and refractive index, which results in lower pigment loading. 

The annual production capacity of high-grade rutile titanium dioxide has reached more than 400,000 tons. It is one of the largest TiO2 manufacturers in China at present. It has more than ten product brands of Taiohua, Jinxing and other brands, and its products are sold in more than 50 countries and regions around the world. It has long maintained the excellent performance of the second overall ranking in the domestic titanium dioxide industry.

In 2021, the European Food Safety Authority concluded that titanium dioxide is no longer safe in foods due to the same concerns over nanoparticles. As a result, titanium dioxide is now banned as a food additive in the EU. Although studies have shown that the absorption of ingested titanium dioxide is low, evidence suggests that titanium dioxide nanoparticles can accumulate in the body over time. Health Canada deemed it safe in 2022 but noted concerns. Unlike their European counterparts, Canadian officials did not consider studies performed with titanium dioxide nanoparticles alone. 

The precipitation of titanium dioxide is a crucial process in the manufacturing of this important industrial material. Titanium dioxide is a white pigment that is widely used in various industries, such as paints, coatings, plastics, and cosmetics, due to its excellent opacity, brightness, and UV resistance.
