Based on the read across considerations the same applies to Acid Black 233:2 whose genotoxic potential is considered negative.


Short description of key information:
Ames test, 5 strains, with and without S9, negative
in vivo Micronucleus, mouse (male), 2000 mg/kg bw, negative

Endpoint Conclusion: No adverse effect observed (negative)

Justification for classification or non-classification

Based on the test results the substance is not classified for genotoxicity under Regulation 1272/2008
