Reference
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

Description of key information

In accordance with column 2 of REACH Annex VIII, the adsorption/desorption screening test does not have to be conducted since (tert-butoxymethyl)oxirane can be expected to have a low potential for adsorption to soil based on the log Kow of 0.97.

Key value for chemical safety assessment

Koc at 20 °C:
9.608

Additional information

As a Koc value is required for exposure calculations, the EPISuite estimated Koc value (EPISuite v4.1/KOCWIN v2.00) of 9.608 for the target substance is included for the chemical safety assessment.
