Safety
Safety Profile
While classified as 'safe as used' by the CIR and officially approved as D&C Green No. 6, the raw material form is identified as irritating to the eyes, respiratory system, and skin. Animal studies showed minimal irritation on rabbit skin and eyes. However, it may induce inflammation or exacerbate pre-existing dermatitis in some sensitive individuals upon direct skin contact. Mutagenicity reports for this compound are conflicting. The European Commission's CosIng database lists it as a hair dyeing colorant under Cosmetics Regulation provisions.
