Overview

E171 - Titanium dioxide

Titanium dioxide (E171) is a bright white pigment used to make foods look whiter and more opaque. It appears on labels as “titanium dioxide” or “E171” and is common in candies, chewing gum, and some tablet coatings. The European Union no longer allows it in food, while it remains permitted in the United States within strict limits.

E160 - Carotenoids

Carotenoids (E160) are a family of yellow, orange, and red color additives used to make foods look bright and consistent. They can come from plants, algae, fermentation, or careful chemical synthesis, and include well-known members like beta‑carotene, lycopene, annatto, and paprika extract. Some carotenoids also act as provitamin A, depending on the type and amount used.

Popular questions

Is titanium dioxide safe?
As a food color (E171), the EU no longer considers it safe and banned food uses in 2022 because potential genotoxicity of nano-sized particles could not be ruled out. Regulators in the U.S., UK, and several other regions still permit it within strict limits.
Is titanium dioxide bad for you?
Typical dietary exposure shows low acute toxicity, but ongoing uncertainty about DNA damage from very small particles led the EU to ban it in foods as a precaution. Occupational inhalation of TiO2 dust—not eating it—is the scenario most closely linked to cancer risk (IARC Group 2B).
Is titanium dioxide safe in sunscreen?
Yes—titanium dioxide is widely accepted as a safe, effective mineral UV filter in sunscreens when applied to skin. The main caution is avoiding inhalation of sprays or loose powders, since respiratory exposure to fine TiO2 particles is the concern flagged by IARC.
What is titanium dioxide used for?
In foods it serves as a whitening and opacifying agent in candies, chewing gum, bakery decorations, sauces, and supplement coatings. Outside food it is used heavily in paints, plastics, paper, cosmetics, and sunscreens for its brightness and UV-scattering properties.
What does titanium dioxide do?
It scatters light to create a vivid white appearance and hides underlying colors or textures, giving foods and tablets a uniform look. In personal care products it blocks and reflects UV light, contributing to SPF protection in mineral sunscreens.
