Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

- Type of method:
- other: estimation based on empirical relationship with the water solubility
- Key result
- Type:
- log Koc
- Value:
- > 3.5 dimensionless
- Temp.:
- 20 °C
- Remarks on result:
- not determinable because of methodological limitations
- Remarks:

Reference
A value of log10Koc for a representative component of the test material was also estimated by a calculation method using a computer program (KOCWIN, Version 2.00, U.S. Environmental Protection Agency). The determined value was significantly greater than 6, confirming the high value obtained through correlation with the water solubility.
Description of key information
Log Koc at 20 °C : >3.5 (empirical relationship with the water solubility; OECD 121, EU C.19)
Key value for chemical safety assessment
Additional information
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.
