Conclusion of the opinion:

The SCCS considers that no sufficient margin of safety could be deduced for the use of 2-chloro-p-phenylenediamine in oxidative hair dye formulations for eyebrows and eyelashes in a concentration of maximum 4.6 % taking into account the scientific data provided. 2-Chloro-p-phenylenediamine is categorised as at least a ‘strong’ sensitiser. A complete chemical characterisation of 2-chloro-p-phenylenediamine is needed. The SCCS is of the opinion, that based on the available data and the lack of a proper in vivo test for gene mutation induction, it is not possible to give a conclusion on the genotoxic potential of 2-chloro-p-phenylenediamine. Therefore, the use of 2-chloro-p-phenylenediamine cannot be considered safe for the consumer.
