Verdict
Azo dye with potential aromatic amine release upon reductive cleavage; prohibited in EU cosmetics; two CAS variants exist—verify identity when sourcing.
US Note
Not an FDA-approved color additive (21 CFR 73/74/82); coal tar hair dye exemption under FD&C Act §601(a) may theoretically apply but substance is effectively unsuitable due to EU ban precedent
