Titanium dioxide (TiO2) is used in a variety of personal care products, including sunscreens, pressed powders, and loose powders, as a UV filter or whitening agent. In lotions and creams (dermal exposure), it is not a risk for adverse health effects. However, when titanium dioxide is inhalable—as it may be when in powder form—it is considered a possible carcinogen by the International Agency for Research on Cancer.Titanium dioxide nanoparticles do not appear to confer any unique health hazards.

How are we typically exposed to titanium dioxide? 

On the other hand, Westerhoff said, there are hundreds of studies showing no adverse effects from the substance.

Hiding power

When E171 is part of a food product, it passes through the digestive system without causing harm because E171 combines with the other ingredients. 

The company was established in 1989. Its predecessor is the titanium dioxide factory, a secondary independent accounting production unit affiliated to CNNC 404. It is a high-grade rutile with an annual output of more than 10,000 tons that imported advanced foreign technology and key equipment earlier in my country. It is also a high-quality titanium dioxide supplier in my country earlier in the market. After years of development, the company now has three production bases in Jiayuguan, Gansu, Baiyin, and Maanshan, Anhui.

Absorption

While the FDA maintains that the regulated use of titanium dioxide is safe, the European Food Safety Authority and some other experts warn of potential, serious health risks.

This work confirms previous studies that show P-25 and other untreated anatase 377 nanoparticles should not be employed in sunscreens because the toxicity of P25TiO2NPs under UV radiation is significant.
