Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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= 2.6 to 3.0 at 20°C.
Key value for chemical safety assessment
Additional information
The solubility in n-Octanol was conducted by flask method according to OECD Guideline 105.
Due to the fact that the test item shows different water soluble amounts, depending on the sample sizes 0.1 g/L and 0.5 g/L the test item does not show a water solubility as a whole but contains different fractions with different water solubilities (see endpoint 4.8). Because of that it was not possible to estimate a general valid log Pow value. The log Pow values also depends on the sample size applied.
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.
