Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Administrative data

Endpoint:
developmental toxicity
Type of information:

The model output shows that the substance could be a developmental toxicant.

Applicant's summary and conclusion

Conclusions:
The model output shows that the substance could be a developmental toxicant. However, the study is disregarded because the reliability can not be assessed (the model documentation is not yet detailed enough to allow a proper assessment).
