Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The partition coefficient log Pow of the test substance was determined to be log Pow = 3.8 at 35°C.
Key value for chemical safety assessment
- Log Kow (Log Pow):
- 3.8
- at the temperature of:
- 35 °C
Additional information
A study was conducted in accordance with OECD TG 117 and Regulation (EC) No 440/2008 method A.8 to determine the partition coefficient of the test substance. Using the HPLC method partition coefficient Pow was determined to be 3.8 at 35 °C. In addition supporting data from the REAXYS database were available. The REAXYS database reports the log Pow to be 3.767 at 25 °C. Both values are in the same range. The additional data support the assumption that the measurement at 35 °C in the key study had no significant influence to the result. Thus, a log Pow of 3.8 was chosen as key value for chemical safety assessment.
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.
