Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Log POW = ca. -1.1
Key value for chemical safety assessment
- Log Kow (Log Pow):
- -1.1
- at the temperature of:
- 25 °C
Additional information
The log POW value can be estimated based on a combination of available data in a Weight of Evidence approach. A statement was provided by a testing laboratory which stated that the octanol-water partition coefficient of the test item was considered to be below zero, although they were not able to confirm this in an experimental study. A calculation of the log POW value of an expected structure of the UVCB substance was conducted using KOWWIN of EPI Suite version 4.1. Additionally, the octanol-water partition coefficient value of each of the structures identified in an analytical report were found to be within the range of Log POW = -1.09 to Log POW = -1.16. Finally, the partition coefficient values of the starting materials were taken into consideration.
Based on the findings, the Log POW value was found to be ca. -1.1 at 25 °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.
