EpiSuite calculation: Koc at 20°C is 21.09 ; Log Koc at 20°C is 1.324

Description of key information

According to the column 2 of Annex VIII of REACH Regulation the study doesn't need to be conducted because the substance has a low potential for adsorption based on a log Kow=-1.84 (log Kow<3).


The Koc value has been estimated by calculation using Episuite (KOCWIN v.2.0.) based on Kow.


The logKow of the substance is -1.84 and the estimated Koc is 21.09 (log Koc=1.324). Considering this calculated value, absorption to soil is not expected.

Key value for chemical safety assessment

Koc at 20 °C:
21.09
