Titanium Dioxide (TiO2): EU Ban, US Status & Global Compliance

What Is Titanium Dioxide?

Titanium dioxide (TiO2, UNII: 15FIX9V2JP) is a white, odorless mineral pigment used as a color additive and opacifier across food, pharmaceutical, cosmetic, and supplement products. In food, it provides the bright white coating on candies, the opacity in frosting and coffee creamers, and the visual uniformity in powdered sugar. In pharmaceuticals, it serves as a pigment and opacifier in tablet coatings and capsule shells. In cosmetics and sunscreen, it functions as both a colorant and a UV filter.

TiO2 is one of the most commercially significant ingredients caught in an active transatlantic regulatory divergence: banned in EU food products since August 2022, still authorized in the United States as a color additive exempt from certification under 21 CFR 73.575, and now under accelerated FDA review amid political and legislative pressure. Companies selling across both markets face compliance obligations that are already diverging and may diverge further.

FDA Regulatory Status (US)

Titanium dioxide is authorized in the United States as a color additive exempt from certification under 21 CFR 73.575 (food), 21 CFR 73.1575 (drugs), and 21 CFR 73.2575 (cosmetics). It is not classified as GRAS -- it holds a distinct color additive authorization, which is a separate regulatory pathway requiring FDA approval and adherence to defined specifications.

The FDA has repeatedly reaffirmed the safety of titanium dioxide for food use. In August 2022, following the EU ban, the FDA reviewed the same body of evidence and maintained its authorization, citing differences in risk assessment methodology and the 1% use limit in the US.

However, the regulatory landscape is shifting:

• May 2025: The MAHA (Make America Healthy Again) Report released by the Trump administration specifically named titanium dioxide among food chemicals "of potential concern," alongside Red 40, propylparaben, BHT, and aspartame.
• 2025: The FDA confirmed it is expediting its review of titanium dioxide as part of its post-market chemical reassessment program.
• July 2025: The Food Chemical Reassessment Act of 2025 (H.R. 4306), introduced by Representatives Schakowsky and DeLauro, lists titanium dioxide among the first-priority chemicals requiring mandatory FDA reassessment. The bill is awaiting a hearing in the House Energy and Commerce Committee.
• 2023: The Environmental Defense Fund (EDF), along with the Center for Environmental Health, Center for Food Safety, Center for Science in the Public Interest, and Environmental Working Group, filed a formal color additive petition (FDA-2023-C-1487) requesting that the FDA revoke the authorization of titanium dioxide as a food color additive.

No formal rulemaking to revoke TiO2 authorization has been initiated. But the combination of the MAHA report, the pending citizen petition, and the Food Chemical Reassessment Act creates meaningful regulatory risk for the first time in the US.

EU Ban & International Restrictions

The EU Ban

On 6 May 2021, the European Food Safety Authority (EFSA) published its updated safety assessment of titanium dioxide (E171) as a food additive. EFSA concluded that a concern for genotoxicity could not be ruled out -- specifically, that TiO2 nanoparticles might accumulate in the body and damage DNA. Given the uncertainties, EFSA determined that titanium dioxide could no longer be considered safe for food use.

The European Commission acted on EFSA's opinion by adopting Commission Regulation (EU) 2022/63 on 14 January 2022, withdrawing authorization for E171 in food. The regulation entered into force on 7 February 2022, with a six-month transition period. Since 7 August 2022, food products containing TiO2 as an additive may not be manufactured or placed on the EU market.

Critical exception: Titanium dioxide remains authorized in EU medicinal products. On 4 August 2025, the European Commission issued a Staff Working Document (SWD(2025) 244 final), based on a European Medicines Agency (EMA) review, confirming that TiO2 will continue to be permitted in pharmaceuticals. The EMA found that no viable alternatives exist for the approximately 91,000 human and 1,600 veterinary medicinal products that use TiO2, and that reformulating the full pharmaceutical portfolio would take more than 12 years when accounting for regulatory post-approval processes.

International Landscape

Following the 2021 EFSA assessment, regulatory authorities in Australia, Brazil, Canada, Japan, New Zealand, the United Kingdom, and the United States all conducted independent reviews and concluded that titanium dioxide remains safe for continued food use.

No other major jurisdiction has followed the EU ban as of early 2026. However, the EU action has re-ignited regulatory scrutiny globally and has created a de facto dual-standard regime for companies operating in both markets.

US Legislative Efforts

California AB 418 (California Food Safety Act)

Titanium dioxide was originally included in California Assembly Bill 418, introduced in March 2023, which sought to ban several food additives at the state level. TiO2 was removed from the bill before it reached Governor Newsom's desk, in part to gain broader legislative support and because of the FDA's position that it remains safe.

Governor Newsom signed the California Food Safety Act on 7 October 2023, banning four other additives (brominated vegetable oil, potassium bromate, propylparaben, and Red Dye No. 3) effective 1 January 2027. Titanium dioxide is not subject to the California ban.

Food Chemical Reassessment Act of 2025

The federal Food Chemical Reassessment Act of 2025 (H.R. 4306) would require the FDA to systematically reassess chemicals that entered the food supply through outdated GRAS determinations or that were reviewed decades ago. Titanium dioxide is listed among the first-priority substances for reassessment, alongside TBHQ, Red 40, Yellow 5, BHA, BHT, and others.

The bill has been introduced but has not advanced past committee. Even without the legislation, the FDA has signaled that TiO2 review is accelerating under its existing authority.

Affected Product Categories

Titanium dioxide's regulatory exposure spans multiple product sectors, each with its own compliance framework:

Food (highest regulatory risk)

• Candy and confections -- white coatings, panned candies, gum
• Baked goods -- frosting, icing, powdered sugar applications
• Dairy products -- coffee creamers, processed cheese, puddings
• Frozen desserts -- ice cream, frozen novelties
• Snack foods -- coated snacks, flavored chips
• Baby food -- some formulations use TiO2 for visual consistency

Dietary supplements

• Tablet coatings and capsule shells frequently contain TiO2 as an opacifier
• Subject to 21 CFR 73.575 in the US; EU food ban applies to supplements sold as food

Pharmaceuticals (low regulatory risk)

• OTC drugs, particularly sunscreen (where TiO2 is an active ingredient under 21 CFR 352)
• Tablet coatings and capsule shells (21 CFR 73.1575)
• Exempt from the EU food ban; EMA confirmed continued authorization in August 2025

Cosmetics and personal care

• Color additive in makeup, lotions, soaps, shampoos (21 CFR 73.2575)
• UV filter in sunscreen products (regulated as OTC drugs in the US)
• Not affected by the EU food ban; separate regulatory framework under EC Regulation 1223/2009

Sun care deserves specific mention: titanium dioxide is one of only two mineral UV filters (alongside zinc oxide) permitted by the FDA monograph for OTC sunscreen. FDA enforcement actions involving TiO2 in sun care focus on CGMP compliance and proper ingredient grading (USP-grade, not food-grade), not on the safety of TiO2 itself.

Industry Response & Reformulation

The EU ban and rising US scrutiny have driven a wave of voluntary reformulation, particularly in confectionery:

• Mars, Inc. removed titanium dioxide from US Skittles production at the end of 2024, after a decade of advocacy pressure. Mars pledged in 2016 to remove TiO2 from all its candy and food products within five years (i.e., by 2021) but missed that deadline. M&Ms and other Mars products still contain TiO2 in the US as of early 2026.
• Dunkin' Donuts announced the removal of TiO2 from its powdered sugar donuts in March 2015, making it one of the earliest major reformulations in the US market.
• So Delicious reformulated its creamers to be titanium dioxide-free.
• Multiple EU-focused manufacturers completed reformulation ahead of the August 2022 ban deadline, replacing TiO2 with alternatives such as rice starch, calcium carbonate, and plant-based opacifiers.

The reformulation trend is accelerating under political pressure from the MAHA initiative and HHS Secretary Kennedy's focus on food additives. Companies with exposure to both US and EU markets are increasingly treating the EU standard as the de facto global benchmark for new product development.

What Companies Should Do

Immediate Actions (All Companies Using TiO2)

1. Audit your TiO2 exposure. Identify every product SKU that contains titanium dioxide across food, supplement, pharmaceutical, and cosmetic lines. Map which products are sold in the EU, US, or both.

2. Monitor the FDA citizen petition (FDA-2023-C-1487) and the Food Chemical Reassessment Act (H.R. 4306). Either pathway could trigger a formal reassessment that leads to use restrictions or revocation.

3. Track MAHA report follow-through. The FDA has committed to expediting its TiO2 review. Watch for Federal Register notices signaling formal rulemaking.

For Companies Selling in Both US and EU Markets

4. Adopt the EU standard for new product development. Designing new products without TiO2 eliminates dual-formulation costs and future reformulation risk. This is increasingly the industry default.

5. Begin reformulation planning for existing US products. Even without a US ban, the direction of travel is clear. Companies that reformulated proactively (Dunkin', Mars) controlled their timeline and narrative. Companies that wait for regulatory action will face compressed timelines and supply chain disruption.

6. Evaluate alternatives now. Rice starch, calcium carbonate, and plant-based opacifiers are commercially available. Pharmaceutical applications have fewer alternatives -- the EMA found that only 5% of authorized medicines could feasibly remove TiO2 with current technology.

For Supplement Companies

7. Review capsule and tablet coating suppliers. Many contract manufacturers use TiO2 as a default opacifier. Request TiO2-free options and confirm supply chain readiness.

8. Watch EU classification. Dietary supplements sold as food in the EU are already subject to the ban. Supplements sold as food in other jurisdictions may face similar restrictions if those countries follow the EU approach.

For Pharmaceutical and Sun Care Companies

9. Maintain CGMP compliance for TiO2 sourcing. FDA enforcement actions (such as the 2023 warning letter to Mr. Lulu LLC for using food-grade rather than USP-grade TiO2 in OTC sunscreen) demonstrate that ingredient grading matters. Use only pharmaceutical-grade TiO2 in drug products.

10. Track the EU pharmaceutical review timeline. While the EMA confirmed continued authorization in August 2025, the Commission committed to ongoing monitoring. A future ban with a multi-year transition period remains possible.

Regulatory Intelligence

The US-EU divergence on titanium dioxide is a leading indicator of broader GRAS reform and international regulatory fragmentation. Companies monitoring TiO2 should also track parallel developments in synthetic food dye regulation, the FDA's broader post-market chemical review program, and state-level food safety legislation modeled on California's AB 418.

Policy Canary monitors FDA enforcement actions, guidance documents, and federal register notices affecting titanium dioxide and hundreds of other regulated substances. Set up monitoring to receive alerts when the regulatory status of TiO2 changes in any jurisdiction that affects your products.
