As of August 7, the use of titanium dioxide in food is banned in the European Union. Europe is taking a precautionary principle approach based on findings from the European Food Safety Authority (EFSA).

Manufacturers use titanium dioxide in some packaging to protect food from exposure to sunlight. Lab studies show it may also help stop bacteria from growing, and break down a gas that makes many fruits and vegetables ripen faster. That can keep products fresher and give them a longer shelf life.

Le lithopone, blanc de lithopone ou blanc de Comines est un pigment blanc composé d'un mélange de sulfure de zinc et de sulfate de baryum, généralement en proportions équimolaires.

In industrial settings, people can be exposed to titanium dioxide through inhalation. Inhalation exposure to titanium dioxide is exceedingly rare for most people.
