Is E171 safe? Health effects

Titanium dioxide is still permitted in the US, UK and many countries, but the EU banned it as a food additive in 2022 after EFSA could no longer rule out genotoxicity from nano-sized particles. It is purely a whitening colour with no nutritional role, so it is easy to avoid if you prefer.

Where you'll find it

Sweets, chewing gum, icing and sauces (outside the EU) and toothpaste.
