The properties of TI02 powder are nothing short of remarkable. Its ability to withstand extreme temperatures, combined with its chemical stability, makes it an ideal candidate for applications ranging from paint manufacturing to the production of advanced ceramics. In paints, TI02 powder acts as a pigment, imparting a brilliant white color that brightens and enhances the final product's aesthetic appeal. Moreover, its high refractive index boosts the paint's hiding power, allowing for more efficient coverage and reducing the need for additional coats.

JECFA previously assessed titanium dioxide at its 13th meeting, at which time the expert committee assigned a “not specified” ADI for the additive due to an absence of significant absorption and a lack of toxicological effects in the available experimental animal and human studies. Since its original evaluation by JECFA, titanium dioxide has become a public point of contention, with its ban being introduced (and then subsequently withdrawn) in California legislation in 2023, a legal battle playing out in the EU over the additive’s ban and classification as a carcinogen in 2022, and the European Food Safety Authority (EFSA) calling titanium dioxide unsafe. However, supporters of titanium dioxide say that claims about its dangers are founded in unreliable studies, and some recent research has supported its safety as a food additive.

The production of lithopone is associated with several environmental concerns, including air and water pollution. Zinc sulfide ore mining can lead to soil erosion and habitat destruction, while sulfuric acid leaching and calcination processes can release pollutants into the air and water. To address these issues, many Chinese lithopone factories have implemented environmental protection measures such as wastewater treatment and emission reduction technologies.
