Description of key information

A range of adsorption/desorption coefficient log values was estimated: 3.08 to 4.29. 89.3% of the components had Log Koc values ranging from 4.17 to 4.29.

Key value for chemical safety assessment

Koc at 20 °C:
19 498

Additional information

The adsorption/desorption coefficients of the test substance were calculated according to Gerstl (1990), Briggs (1981) and Nendza (1998) based on the experimental values of n-octanol/water partition coefficient (OECD 117).


A range of adsorption/desorption coefficient log values was estimated: 3.08 to 4.29. 89.3% of the components had Log Koc values ranging from 4.17 to 4.29.


In a conservative approach, the highest value (log Koc = 4.29; Koc = 19498) was selected for the chemical safety assessment.
