Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
No experimental data on the determination of the Log Koc are available.
The Log Koc as determined via a QSAR calculation, was found to be 3.71. This indicates that the substance tends, to a certain extent, to undergo adsorption to solid matter. The Koc information has been taken into account in the calculation of the PNECs according to the EPM method.
Key value for chemical safety assessment
- Koc at 20 °C:
- 5 129
Additional information
The log Koc was determined using EpiSuite's KOCWIN model to be 3.71 when estimated via the molecular connectivity index.
The method using the log Kow value as starting point yielded a log Koc value of 4.86. According to the QSAR's user manual, the molecular connectivity index method is somewhat more accurate. Therefore, a log Koc of 3.71 is retained for the risk assessment.
