Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The log Koc for 3 components of the substance were determined to be 4.44 (peak area: 32%), >5.63 (peak area: 32%) and >5.63 (peak area: 36%).
Key value for chemical safety assessment
Additional information
The HPLC method at neutral pH using log Koc reference data was applied for the determination of the adsorption coefficient (Koc) of the substance. The mobile phase was 55/45 (v/v) methanol/water. The column temperature was 35°C. In the HPLC chromatogram of the test substance solution (in m-cresol), 3 peaks were observed. The log Koc for 3 components of the substance were determined to be 4.44 (peak area: 32%), >5.63 (peak area: 32%) and >5.63 (peak area: 36%). The study was performed according to EC C.9 and OECD 121 and in accordance with the principles of GLP.
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.
