Description of key information

THe Koc was determined via the OECD HPLC test, the outcome is that the Koc of the test substance is = < 21

Key value for chemical safety assessment

Koc at 20 °C:

Additional information

The adsorption coefficient (Koc) of the test substance was determined in a GLP-compliant test according to the OECD Guideline for the estimation of the Adsorption Coefficient (Koc) on Soil and Sewage Sludge using High Performance Liquid Chromatography (HPLC), Draft Guideline (June 2000).

Using the corresponding log Koc values of the reference items from the OECD guideline, the regression coefficients were calculated. The log Koc value of the test substance was calculated from the calibration equation. The adsorption coefficient (Koc) of the test substance was estimated to be Koc = < 21. This value indicates a mobile character of the test substance
