Titanium Dioxide: Vegan Mineral, EU Food Ban

Titanium dioxide is a mineral pigment, not an animal product, so by source it is compatible with vegan and vegetarian claims, and it is gluten-free. Its complication is regulatory rather than animal-derived: the EU removed E171 as a permitted food additive in 2022 over a genotoxicity concern, while it remains in use in cosmetics, sunscreens and supplements. Cruelty-free is a separate testing question.
