Description of key information

The adsorption/desorption properties of the substance EC 939-457-4 were not investigated in any experimental study because the substance and its relevant degradation products decompose rapidly (by analogy) and because the substance has a low octanol-water partition coefficient log Kow (by analogy). However, for the aim of the exposure and risk assessment, a log Koc 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 = 2.112 and Koc = 129.420

Key value for chemical safety assessment

Koc at 20 °C:
129.42
