Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel concluded that this ingredient, when reviewed as part of a group of phenylenediamine derivatives, is safe for use as a hair dye ingredient within current practices and concentrations. However, it is explicitly deemed unsafe for direct dermal coloring applications, such as temporary black henna tattoos, and for use in eyelash and eyebrow dyes. The precise maximum concentration for N,N-DIETHYL-P-PHENYLENEDIAMINE SULFATE specifically was not detailed in the available CIR review. The SCCS has not issued a specific opinion on this compound (CAS 6283-63-2).
