Description and Uses

Acid Violet 43 is an anthraquinone color that functions as a colorant in cosmetic formulations (Wenninger, Canterbery, and McEwen 2000). Batches of Acid Violet 43 that are certified by the Food and Drug Administration (FDA) as meeting the standards and specifications described in the Code of Federal Regulations (21 CFR 73 & 74) are named Ext. D & C Violet No. 2 (FDA 1976). Most of the available safety test data are from studies of Ext. D & C Violet No. 2 conducted to support FDA listing this color for drug and cosmetic use.

Acid Violet 43 is an anthraquinone colour used in semi-permanent hair dye formulations at a maximum concentration of 0.5% active dye. According to the EU Cosmetics Directive 76/768/EEC, Annex IV Part I List of Colouring Agents, Acid Violet 43 is allowed as CI 60730 in cosmetic products except those intended to come into contact with mucous membranes.
