• SCCS: four requests for Opinion (October 6, 2014)
1. In light of the data provided, does the SCCS consider HC Blue 18 (B122) safe when used as a direct hair colouring agent at on-head concentration up to 0.35% in non-oxidative as well as in oxidative hair dye formulations?
In light of the data provided, SCCS considers that the use of HC Blue 18 (B122) as an ingredient in non-oxidative hair dye formulations at a maximum concentration of 0.35% on the head is safe.
Concerning oxidative conditions, the safety cannot be assessed because stability assessment was not adequately performed.

SCCS considers HC Blue 18 as a moderate sensitiser.
