Endpoint:
adsorption / desorption: screening
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the substance has a low octanol water partition coefficient and the adsorption potential of this substance is related to this parameter
the study does not need to be conducted because the substance and its relevant degradation products decompose rapidly

Description of key information

According to column 2 of REACH Annex VIII, the study does not need to be conducted because the substance is expected to have a low potential for adsorption (Log Kow less than or equal to 3) and both the substance and its degradation products decompose rapidly (readily biodegradable meeting the 10 day window). However, a value has been calculated using a QSAR due to the need of having for the environmental risk assessment.

Key value for chemical safety assessment

Additional information

There are two Koc results provided by EPIWIN which are similar (MCI and LogKow methods), but the validity of the model for this substance is unknown.
