Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 ≤ 2.41
Key value for chemical safety assessment
- Log Kow (Log Pow):
- 2.41
- at the temperature of:
- 20 °C
Additional information
The octanol-water partition coefficient of the substance was determined in the weight of evidence approach. The highest value, obtained applying KOWWIN v1.68 (US EPA Episuite v4.1) to monomeric C11 linear constituent, was selected as worst case. Results of respective calculations for shorter chains and dimeric constituents are significantly lower (from -0.58 to 1.35). As underestimated appears the determination based on solubility ratio in n-octanol and water (< -1.53). Result of the experiment performed according to OECD Guideline 117 (HPLC method) confirms only that the log Pow range is between -5.2 and 4.2.
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.
