Description of key information
Koc was estimated using the KOCWIN™ v2.00 module of EPI Suite™ v.3.20. Log Koc estimation is 3.91 which corresponds to 8038 L/kg.
Key value for chemical safety assessment
- Koc at 20 °C:
- 8 038
Additional information
The value of 3.91 is the worst case value as obtained from the four major constitutents of the substance, in terms of adsoprtion. It is based on the log Kow method, as the variability of these values is large. Hence this method is considered to better represent the adsorption behaviour of the substance than the values obtained with the MCI method (3.05). The Koc value of the substance indicates, that the substance adsorbs strongly to soils and sediments. Since however the substance is readily biodegradable, contamination of environmental compartments like surface waters, sediment, soil and groundwater via horizontal and vertical transport is not expected. Hence, the issue of transport and distribution in these compartments of the environment is of no concern.

Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
