What it is

Titanium dioxide is a naturally occurring mineral that is processed into a fine white powder. It is composed of titanium and oxygen atoms. It is widely used in many products beyond food, including paints, cosmetics, and sunscreens.

Why it's used

In food, titanium dioxide is used as a white color additive. It helps make foods appear brighter and more opaque. It can be found in products like candies, chewing gum, baked goods, and dairy products.

Health notes

Titanium dioxide is an FDA-approved color additive for use in food. JECFA has evaluated titanium dioxide and set an acceptable daily intake (ADI not specified). The European Food Safety Authority (EFSA) concluded in 2021 that it could no longer be considered safe as a food additive, leading to its ban in the EU in 2022. The FDA continues to permit its use in the United States, and it is not part of the FDA's announced plan to phase out petroleum-based synthetic dyes.
