On request from: European Commission
SCCS Number: SCCS/1536/14
Adopted on: 23 September 2014

Conclusion of the opinion:

The SCCS is of the opinion that the use of Acid Orange 7 as a hair dye ingredient up to a final on-head concentration of 0.5% under non-oxidative conditions does not pose a risk to the health of the consumer. As the stability of Acid Orange 7 under oxidative conditions is not known, no final decision can be taken on its safe use in oxidative hair dye formulations. The SCCS has no information on the use concentrations of Acid Orange 7 as a colorant in other cosmetic products. The aggregate exposure is not known and, therefore, the safety of Acid Orange 7 as a cosmetic colorant cannot be assessed.
