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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 > 8 at ca. 20 °C (Weight of Evidence: EU Method A.8, estimation method (solubility ratio) + (Q)SAR)
Key value for chemical safety assessment
Additional information
The octanol/water partition coefficient has been estimated from the ratio between the solubility in 1-octanol and in water, and using two independent (Q)SAR models (EPI Suite KOWWIN and VEGA ALogP). The value calculated by the KOWWIN model (log Pow = 8.12) was considered the most reliable one. An exact log Pow could not be estimated using the solubility ratio because the substance appeared completely miscible in octanol (solubility > 100000 mg/L). The value calculated by ALogP is considered of lower reliability because the substance does not fit completely with the applicability domain of the model.
A log Pow > 8 is taken as a conservative key value for the chemical safety assessment for this substance.
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.
