On request from: European Commission
SCCS Number: SCCS/1585/17
Adopted on: 7 March 2017

Conclusion of the opinion:

1. In light of the new data provided, does the SCCS consider Basic Blue 99 (C059) safe as direct hair dye substance in hair dye formulations with a concentration on-head up to a maximum of 1.0%?

The SCCS cannot conclude on the safety of Basic Blue 99 (C059) because it is composed of several substances and isomeric forms, with a large variability between the composition of different batches. Also, the toxicological data provided in the previous submission do not relate to the material specifications provided for the current assessment. The safety assessment of Basic Blue 99 will require a clear well-defined set of specifications for the composition of the material intended to be used in cosmetic products as well as supporting toxicological data relating to a representative composition.

2. Does the SCCS have any further scientific concerns with regard to the use of Basic Blue 99 (C059) in cosmetic products?
