The questions everyone asks
about titanium dioxide

By Kailah Shannon — Founder of MG Naturals. Cosmetic Formulator since 2014.

QUICK ANSWER

Titanium dioxide is banned as a food additive across the EU (since August 2022) but remains permitted in cosmetics worldwide. "Non-nano" addresses one safety concern but not all of them. "Mineral" and "natural" are unregulated marketing terms — neither guarantees a product is titanium dioxide-free. You can absolutely get good coverage without it; it just takes better formulation. Below are the questions we're asked most often, with direct answers.

Is titanium dioxide banned?

In food in the EU — yes, since August 2022. In cosmetics — no, but the science that triggered the food ban (genotoxicity that couldn't be ruled out) doesn't change because you're putting it on your face instead of in your mouth.

PEER-REVIEWED EVIDENCE

Banned in your food. Still in your foundation.

In May 2021, the European Food Safety Authority ruled titanium dioxide could no longer be considered safe as a food additive, because "a concern for genotoxicity could not be ruled out." No safe daily intake could be established. The EU banned it in food across all member states in August 2022. The same molecule remains permitted in cosmetics. Europe decided this ingredient isn't safe enough for your child's lollies. The mechanism that triggered the ban — DNA damage — doesn't stop because you applied the molecule to skin instead of swallowing it.

If it's allowed in cosmetics, why avoid it?

Because "allowed" means "no regulator has been forced to ban it yet." It does not mean "safe for daily use on facial skin for forty years." Those are different questions. Most ingredient bans happen decades after the science is clear.

Isn't it just a mineral?

It's mineral-derived. So is asbestos. "Natural origin" tells you nothing about whether something belongs on your face every day.

What about non-nano? Isn't that the safe one?

Non-nano addresses one risk vector (particle size) and ignores others (photoreactivity, daily exposure, inhalation from powders, cumulative load). It's a partial answer marketed as a complete one.

Can you really get good coverage withou1t it?

Yes. It's harder. It's more expensive. It takes better formulation. That's exactly why most brands won't do it.

Why do brands hide it under "may contain"?

Because shade-specific pigments don't always have to be listed in the main ingredient list — "may contain" lets brands include or exclude TiO₂ across a shade range without committing to listing it. It makes ingredient-conscious shopping harder. We think that's the point.

Is mineral makeup automatically better for sensitive skin?

No. "Mineral" is a marketing word, not a guarantee. Plenty of mineral makeup is loaded with titanium dioxide and bismuth oxychloride — both of which can be irritating, drying, and reactive on compromised skin.

Should everyone avoid titanium dioxide?

We don't do blanket panic messaging. We do believe people deserve real information and a real alternative. That's what we built.

Why does MG Naturals talk about this so openly?

Because if we're going to draw a line this clearly, we should be able to defend it just as clearly.

Frequently asked questions

Is titanium dioxide a carcinogen?

The International Agency for Research on Cancer (IARC) classifies titanium dioxide as Group 2B — "possibly carcinogenic to humans" — based on inhalation evidence in animal and occupational studies.

What's the difference between E171 and CI 77891?

They refer to the same chemical — titanium dioxide. E171 is the food additive code (now banned in the EU); CI 77891 is the Colour Index code used in cosmetic labelling.

Is titanium dioxide-free sunscreen as effective?

Yes — when zinc oxide is used as the active mineral filter. Zinc oxide provides broad-spectrum UVA and UVB protection and is the active in many high-quality natural sunscreens. Always check the SPF rating, not the active ingredient name.

Does Australia plan to ban titanium dioxide?

As of 2026, no. Food Standards Australia New Zealand (FSANZ) reviewed the EFSA evidence and concluded no regulatory action is required at current Australian exposure levels. Cosmetics regulation falls to the Therapeutic Goods Administration (TGA), which permits titanium dioxide in cosmetics and sunscreen.

How can I check if a product I already own contains titanium dioxide?

Read the ingredient list on the product or the brand's website. Look for "titanium dioxide," "TiO₂," "CI 77891," or "E171." If a lipstick or other shade-varying product shows "may contain (+/-) CI 77891," it's possible — but not guaranteed — to be in your specific shade. Contact the brand directly if you need certainty.

Are MG Naturals products certified titanium dioxide-free?

Every formula is documented as titanium dioxide-free in our internal specifications, and every ingredient is listed in plain English on the product page. We don't currently carry a third-party "TiO₂-free" certification because no such standardised certification exists — but full ingredient transparency is the most reliable verification we can offer.
