Titanium dioxide (E171) is halal. It is a mineral-based white colour and opacifier with no animal ingredients, so all schools consider it permissible. Note that the EU banned it in food in 2022 following a safety review — a health decision, not a halal one — while it remains permitted in many other countries.

The short version
Titanium dioxide is a mineral-based white colour with no animal source — so it is halal.
What it is
Titanium dioxide (E171) is used to make foods, coatings and pills bright white and opaque — in sweets, icing, sauces and supplements. It is derived from a mineral, not from any animal.
The EU ban is about safety, not halal
In 2022 the EU banned titanium dioxide as a food additive after a safety review raised questions about it. That is a health decision, and it does not change the halal ruling — where it remains permitted, it is halal by ingredient.
