Effective November 23, 2018, the Office of Environmental Health Hazard Assessment (OEHHA) is adding gentian violet
to the list of chemicals known to the state to cause cancer for purposes of the Safe Drinking Water and Toxic Enforcement Act of 1986 (Proposition 65). At a public meeting on November 1, 2018, the Carcinogen Identification Committee (CIC) in its official capacity as the “state’s qualified experts” (SQE) determined that gentian violet
were clearly shown by scientifically valid testing according to generally accepted principles to cause cancer. Regulations for the listing of chemicals by the CIC are set out in Title 27, California Code of Regulations, section 25305(a)(1).
