The UK proposes to limit the use of Oxybenzone in cosmetic products, aligns with the EU

London, UK, May 2025 - The UK is moving to tighten controls on oxybenzone in cosmetic products, formally notifying the World Trade Organization on 8 May 2025 of its intention to introduce new concentration limits. The proposal, set out in the draft Cosmetic Products (Restriction of Chemical Substances) Regulations 2025, would bring UK requirements largely in line with existing EU rules.

Under the draft regulation, the use of 2-Hydroxy-4-methoxybenzophenone, commonly known as oxybenzone (CAS 131-57-7), would be capped at 6% in face, hand, and lip products (excluding propellant and pump sprays), 2.2% in body products (including sprays), and 0.5% in all other cosmetic products. Where oxybenzone is used solely to protect product formulation at up to 0.5%, its use as a UV filter would be further limited to 5.5% in face and lip products and 1.7% in body products.

The proposed limits are expected to have a notable impact on cosmetic brands, manufacturers, and retailers, many of whom may need to reformulate products to remain compliant. Some UK retailers have already taken action—most notably Holland & Barrett, which has begun removing oxybenzone-containing products from its shelves. EU manufacturers, however, may face fewer disruptions, as similar restrictions have been in force across the EU since 2022.

The UK’s alignment follows a 2024 final opinion issued by the Scientific Advisory Group on Chemical Safety in Consumer Products (SAG-CS) under the Office for Product Safety and Standards, which recommended adopting these thresholds. By comparison, both the United States and Canada permit oxybenzone use up to 6%, Australia allows up to 10%, and Japan applies a 5% limit.

Oxybenzone is widely used as a UV filter in sunscreens and other cosmetic products offering UV protection. Environmental concerns have driven regulatory scrutiny, with studies cited by the National Oceanic and Atmospheric Administration and the US National Academy of Sciences pointing to harmful effects on aquatic life, including fish, sea urchins, and algae. These concerns have already led to outright bans in sunscreen products in Hawaii and Palau.

The UK regulation is expected to be adopted by 21 July 2025 and enforced from 21 January 2026. Products already placed on the market before that date may continue to be sold until 21 July 2026.
