Over the past decade, the cosmetics industry has faced increasing pressure to eliminate animal testing from all stages of product development. Both the European Union (EU) and the United Kingdom (UK) have long established comprehensive bans on animal testing for cosmetics. However, recent developments in regulatory practices—particularly the intersection between cosmetics regulations and broader chemical safety rules like REACH (Registration, Evaluation, Authorisation, and Restriction of Chemicals)—are sparking new debates. While the bans remain firmly in place, the fine line between the Cosmetic Products Regulation (CPR) and REACH has led to legal cases and calls for further clarification.
