The agency makes this exception for several approved color additives. 

For people in occupational settings that increase the risk of titanium dioxide exposure, taking protective measures is helpful. This may include wearing protective equipment, such as respirators, and using ventilation systems.

Of the two methods of extraction, the sulphate process is currently the most popular method of producing TiO₂ in the European Union, accounting for 70 percent of European sources. The remaining 30 percent is the result of the chloride process. On a global level, it is estimated about 40-45 percent of the world’s production is based on the chloride process.

Then, there’s ultrafine-grade, also known as nanoscale titanium dioxide. This is used for its ability to scatter lightly as an ultra-fine powder. This gives it the ability to lightly absorb into the skin while providing a bit of transparency. Below, we’ll go more into the cosmetic uses of these two forms of titanium dioxide.
