Is titanium dioxide banned in the US?

No. It remains a permitted colour additive under FDA rules. It is banned as a food additive in the European Union, which is where most of the coverage originates.

Is titanium dioxide in toothpaste and sunscreen a problem too?

Those are different exposures and different rules — the EU food ban does not cover cosmetics, where titanium dioxide remains permitted, including as a mineral sunscreen filter. Swallowing and applying are not the same question.

Read for 'titanium dioxide' or E171 on ingredients lists, and check supplement and medication capsules, which are a larger source than most people expect.

Answer

Is titanium dioxide safe in food?

Short answer

Regulators disagree, and that disagreement is the honest answer. EFSA concluded in 2021 that titanium dioxide could no longer be considered safe as a food additive because genotoxicity could not be ruled out, and the EU ban took effect in 2022. The US FDA still permits it as a colour additive, having not reached the same conclusion from the same data.

What happened, in order

E171 is titanium dioxide used as a whitening and opacifying colour — sweets, icing, chewing gum, sauces, supplements
France suspended it in food in 2020, ahead of the rest of the EU
EFSA's 2021 opinion could not rule out genotoxicity and declined to set an acceptable daily intake
The EU ban applied from February 2022 with a transition period ending that August
The FDA continues to permit it; a 2023 California bill that would have banned it dropped titanium dioxide before passage

Why two regulators read it differently

The disagreement is about nanoparticles. A share of food-grade titanium dioxide is small enough to fall in the nanoparticle range, and EFSA judged that the available studies could not exclude DNA damage from that fraction. The FDA's position rests on the absence of demonstrated harm at permitted levels and on limits for particle size and purity.

Neither agency has claimed that titanium dioxide is proven harmful. The difference is what each does when a question cannot be closed — which is a policy difference as much as a scientific one, and it is worth naming as such rather than treating either side as obviously right.

Where you will still meet it

In the US: confectionery coatings, frosting, coffee creamer, some sauces and dressings, and a very large share of supplement and medication capsules. On a US label it appears as titanium dioxide; on any remaining international label as E171.

Olive Detective puts E171 in its highest-concern additive group, alongside the azo colours and sodium nitrite. That is a precautionary position that follows the EU reading, and it is a category-level flag rather than a claim about any particular product.
