Full toxicological data required.Up to 0.02% associated with low sensitisation (from SCCNFP/0743/03); current higher use levels (200 ppm = 0.02%) cause sensitisation induction and elicitationWidespread contact allergy in Europe; current use levels inadequate for protection; requires full toxicological assessment including genotoxicity; later confirmed unsafe even at 200 ppm (SCCS/1459/11) and banned from EU cosmetics in 2017
