Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Results and discussion

Test results
Genotoxicity:
negative
Additional information on results:
Model assessment:
Prediction is "NON mutagen", but the result may be not reliable as only moderately similar compounds with known experimental value in the training set have been found.

Applicant's summary and conclusion

Conclusions:
Interpretation of results (migrated information):
negative

The obtained results are disregarded as the substance is out from the applicability domain of the model.
