In June 2022, Health Canada weighed in on the debate, releasing a report on the safety of titanium dioxide. Their expert panel reviewed toxicity studies, including ones involving genetic damage.

Titanium dioxide (TiO2) is a fine white powder or dust that occurs naturally. It was first intentionally produced for use as a white pigment in 1923.
