In the light of the new data provided, SCCS considers that the use of 2,6- dihydroxyethylaminotoluene as an ingredient in oxidative hair dye formulations at a maximum concentration of 1.0% on the head is safe.

2. Does the SCCS have any further scientific concerns with regard to the use of 2,6-Dihydroxyethylaminotoluene (A138) in cosmetic products?

2,6-Dihydroxyethylaminotoluene is a secondary amine, and thus, it is prone to nitrosation. It should not be used together with nitrosating agents. Nitrosamine content should be <50 ppb="" p="">
