Applicant's summary and conclusion

Interpretation of results:
other: Not classified according to the CLP Regulation (EC 1272/2008)
Conclusions:
The substance is expected to be potentially not eye irritant, on basis of the estimation.
Executive summary:

The eye damage / irritation potential of the substance was investigated using a specific QSAR model, developed to predict the eye damage / irritation potential 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 developed in accordance with the OECD principles (details in the documentation attached).

Based on the estimation, the substance is expected to potentially not eye irritant. The estimation resulted to be in the applicability domain of the model.
