Administrative data

Endpoint:
hydrolysis
Data waiving:
study technically not feasible
Justification for data waiving:
the study does not need to be conducted because the substance is highly insoluble in water

Results and discussion

Applicant's summary and conclusion

Conclusions:
The study is considered to be not scientifically justified.
Executive summary:

The substance has, based on QSAR, an extremely low water solubility well below 0.1mg/L, which is consistent with expectation based upon chemical structure. The substance therefore meets the criteria for data waiving and the study is considered not scientifically justified.
