mutagenic potential (based on QSAR/QSPR prediction)

Applicant's summary and conclusion

Conclusions:
Positive results in AMES test.
Executive summary:

The gene mutation potential on bacteria of the substance was investigated using a specific QSAR moled, developed to predict the gene mutation potential in bacteria for dyes. The existing QSAR models have strong limitations to predict ionic complex structures as the organic dyes are, and consequently they provide unreliable results. The QSAR modelling was developped in accordance with the OECD principles (details in the documentation attached).

Based on the estimation, the substance is expected to be able to give positive results in AMES test system. The estimation resulted to be in the applicability domain of the model.

Conclusion

Positive result in AMES test.
