Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Partition coefficient Log Pow:
1.81 (HPLC method, OECD guideline 117)
2.44 (shake flask method)
2.57 (HPLC method)
1.59 (HPLC method)
2.47 (no method stated)
2.343 (shake flask method, 37°C)
2.19 (no method stated)
Key value for chemical safety assessment
- Log Kow (Log Pow):
- 2.3
- at the temperature of:
- 20 °C
Additional information
Several independant sources reporting values for partition coefficient n-octanol/water log Pow in the small range between 1.59 and 2.57. The three references with highest reliabilities due to best documentation of methods and experimental details were used to calculate an average value. One of these studies was performed according to OECD guideline. References with incomplete documentation of experimental details and where no method is stated as well as one reference where the measurement was performed at 37°C have not been used for the average calculation.
The average value of log Pow of 2.3 was chosen as the 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.
