Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Estimated based on solubility ratio:
Log Pow= 1.3 to 1.9 at 20°C
Key value for chemical safety assessment
- Log Kow (Log Pow):
- 1.9
- at the temperature of:
- 20 °C
Additional information
The solubility in n-octanaol was conducted by flask method according to OECD Guideline 105.
The test item is a complex mixture of components, which differ in their chemical behaviour. lt is evident that each of the single components of this mixture shows different properties, in particular concerning partition coefficient n-octanol/water (Pow). lt can be expected that the different components show different distributions between the n-octanol phase and the water phase.
Due to this, the log Pow can only be estimated from the single solubilities in n-octanol and in water.
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.
