Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Key value for chemical safety assessment
Additional information
The n-octanol/water partition coefficient of the test material was determined in accordance with standardised guidelines OECD 107 and EU Method A.8.
The preliminary test indicated that the test material was weakly soluble in n-octanol (< 0.01 g/L). The solubility of the test material in water was previously determined to be > 1000 g/L. The Pow and log Pow were determined to be < 0.0001 and < -4, respectively. Since the log Pow was found to be negative, the study was considered to be complete and no further testing was initiated.
The study was performed in line with GLP and an accepted standardised guideline with a high level of reporting. The study was assigned a reliability score of 1 in accordance with the criteria of Klimisch (1997) and considered suitable for assessment as an accurate reflection of the test material.
The available data are considered to be complete and the result determined, log Pow < -4 at 20 °C, was taken forward for risk assessment.
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.
