Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Under the test conditions, log Pow of test substance was determined to range (concentration dependent) between <-3.3 to <-4.0 at 21 ±1°C. The study was performed in accordance to EU method A.8 and in compliance to GLP.
Key value for chemical safety assessment
- Log Kow (Log Pow):
- -3.3
- at the temperature of:
- 21
Additional information
A study was performed to determine the partition coefficient of the test substance according to EU method A.8 in compliance with GLP using the shake flask method.
To different volumes of this solution different volumes of water were added (saturated with n-octanol) to achieve different phase ratios. The samples were shaken for 60 min at 21 °C and then centrifuged at 5000 rpm. The phases were separated and the concentration of the test substance in both phases of the samples were analysed by spectral photometer.
The partition coefficient of the test substance is concentration dependent. For this reason no average value and no standard deviation has been determined.
Under the test conditions, log Pow of test substance was determined to range between <-3.3 to <-4.0 at 21 ± 1 °C.
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.
