Why Did Europe Ban Titanium Dioxide?

While the conclusions of the EU expert panel were considered in this report, Health Canada's Food Directorate conducted its own comprehensive review of the available science. This included evaluating new scientific data that addressed some of the uncertainties identified by the EU expert panel and were not available at the time of their review.    

Titanium dioxide can amplify and brighten white opacity because of its exceptional light-scattering properties. In food and drugs, these properties help to define colors clearly and can prevent products from UV degradation. 

4. Emergency procedures The MSDS should outline steps to take in the event of an accident or exposure to lithopone, including first aid measures and contact information for emergency responders.

It is recommended to store Titanium Dioxide in a well-maintained and dry environment, safeguarding it from exposure to elevated temperatures, open flames, or aromatic chemicals. When transporting Titanium Dioxide pigments, they are commonly packaged in paper bags weighing 25 kg (50 lb) or in large bags constructed from woven polypropylene materials.

The ROS seemed to be endlessly produced by P25TiO₂NPs upon irradiation, since the values detected after 6 h are similar to the ones after 3 h. However, the amount of vitamin B2 in the surface of the NPs proved to be enough to decrease the ROS detected even after 6 h. Statistical analysis showed a significant difference between C and A. p < 0.05
