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 and its relevant degradation products decompose rapidly

Description of key information

For PNEC derivation according to the equilibrium partitioning method, a Koc value is required. As it was not mandatory to have a log Koc value measured experimentally (the substance and its degradation products decompose rapidly), a value was estimated from the available log Kow value using the following equation from TGD Part III (for nonhydrophobic substances): log Koc = 0.52 x log Kow + 1.02 = 0.188 and Koc = 1.54.

Key value for chemical safety assessment

Koc at 20 °C:
1.54
