The risks associated with titanium dioxide exposure depend on a variety of factors, including the form of the mineral, the route of exposure (such as being inhaled or consumed), and the duration and intensity of exposure.

Overall, the precipitation of titanium dioxide is a complex process that requires careful control of various factors to achieve the desired product properties. By optimizing the precipitation percentage and carefully monitoring the precipitation process, manufacturers can produce high-quality titanium dioxide that meets the stringent requirements of their customers in the paints, coatings, plastics, and cosmetics industries.

FAQ – EFSA 2021 safety assessment of titanium dioxide (E171)

Most notably, a European Food Safety Authority safety assessment published in May 2021 pointed to genotoxicity concerns, as suggested by previous research. Genotoxicity is the ability of chemicals to damage genetic information such as DNA, which may lead to cancer.
