Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 is determined to 3.15 at 20 °C.
Key value for chemical safety assessment
- Log Kow (Log Pow):
- 3.15
- at the temperature of:
- 20 °C
Additional information
A study according to OECD TG 117 HPLC method was conducted (BASF AG 1994a, 94L00087) to determine the log Pow value. Using the HPLC method the log Pow was determined to be 2.9 at 22 °C. Furthermore a study was conducted according to OECD TG 107 shake flask method (BASF AG 1994b, 94L00087) to verify the result of the HPLC. Using 6 replicates the log Pow was determined to be 3.15 at 20 °C. In general the results from the shake flask method will be regarded as more reliable. The log Pow of 3.15 was regarded as worst case assumption and thus was chosen as key
value for chemical safety assessment. The result is supported by a calculation using SPARC creating a value of 2.82 based on a scientifically calculation model.
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.
