Regulatory Status

EU EU Status prohibited
US US Status prohibited
US Notes Fully prohibited in the United States. FD&C Violet No. 1 was delisted by the FDA in 1973 (effective April 10, 1973) following Japanese studies linking the dye to carcinogenicity in female rats. The provisional listing for drug and cosmetic use was terminated. Delisted color additives are not permitted for any use in the US under 21 CFR 81.10. Any US cosmetic product containing CI 42640 would be considered adulterated under the FD&C Act.
