UK Tightens Rules on Benzophenone-3 in Cosmetic Products to Enhance Consumer Safety

On 8 May 2025, the United Kingdom formally notified the World Trade Organization (WTO) of a new regulatory measure titled the Cosmetic Products (Restriction of Chemical Substances) Regulations 2025. This step aims to strengthen consumer protection by revising the permitted levels of benzophenone-3, a common UV-filter used in cosmetic products.

The amendment, which modifies the Cosmetics Regulation (EC No 1223/2009) as it applies in Great Britain, follows expert guidance from the Scientific Advisory Group on Chemical Safety of Non-Food and Non-Medicinal Consumer Products (SAG-CS). The group advises the UK Government independently on chemical risks in consumer goods, with a strong emphasis on safeguarding public health.

Implementation Timeline

• Effective Date: 21 January 2026

• Transitional Period: Products containing benzophenone-3 already on the market before this date may remain available until 21 July 2026

This move aligns with the UK’s commitment to ensure that only safe cosmetic products are accessible to consumers, reflecting evolving scientific risk assessments and reinforcing public trust in regulatory vigilance.
