Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 Koc < 1.32 at 25 °C
Key value for chemical safety assessment
Additional information
The determination of the absorption coefficient (Koc) of the test substance was performed according to the OECD guideline 121 (2001) and the method C.19 of the EC Directive 2001/59. The test item solution was injected three times and the combined reference solution was injected six times. The log Koc was calculated using a regression curve (log k' vs. log Koc) and was found to be < 1.32 which is equal to a KOC value of < 21. This value indicates that test item is not absorbed by organic carbon in soil. The substance is very mobile.
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.
