About

A triarylmethane dye listed in EU Annex II and classified as a Category 2 carcinogen that is prohibited in all cosmetic products.

Basic Violet 3 (Crystal Violet, CI 42555, CAS 548-62-9) is listed in EU Annex II (reference II/380) of the Cosmetics Regulation, meaning it is strictly prohibited in all cosmetic products. It is classified as a Category 2 carcinogen under CLP and has been associated with genetic damage and liver toxicity. Despite historical use as a preservative and colorant in cosmetic products, the weight of evidence regarding its carcinogenicity led to its complete prohibition. Any detectable presence in cosmetic products constitutes a regulatory violation.

Known concerns

  • EU Annex II prohibited - complete ban in cosmetics
  • CLP Category 2 carcinogen
  • Genotoxic potential
  • Associated with liver and kidney toxicity
  • Historic use as preservative but now banned
