Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 adsorption coefficient on soil (Koc) of the test item was determined according to OECD guideline no. 121 and EU test method C.19. The Koc and log Koc of the test item was determined to be 40000 and 4.6, respectively.
Key value for chemical safety assessment
- Koc at 20 °C:
- 40 000
Additional information
Using the HPLC method the adsorption coefficient on soil (Koc) of the test item was determined according to OECD guideline no. 121 and EU test method C.19. The log Koc-value of the test item fell within a range of ± 0.1 units, thus the test is satisfactory. As the test item exhibits a high retention time (ca. 26 minutes) an extrapolation was necessary because no adequate calibration substance with a large Koc value were found.
The Koc and log Koc of the test item at 25 °C was determined to be 40000 and 4.6, respectively.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.
