Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Details on results:
Based on Acute to chronic toxixicty ratios of classes of substances. Applicability domain log Kow 8. log Kow used: 8.993. The prediction is on the limit of the applicability domain of the model.

Applicant's summary and conclusion

Conclusions:
The model predicts a toxicity level above the solubility limit. This is consistent with the existing experimental data.
