Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Koc >4.3 x 10⁵ and log Koc >5.63, OECD 121 and EU Method C.19, Baltussen 2013b.
Key value for chemical safety assessment
Additional information
In the key study the adsorption coefficient of the test material was investigated in accordance with standardised guidelines by applying the HPLC method using soil-adsorption-reference data. The test material was compared to several reference compounds and the adsorption coefficient calculated. Under the conditions of this study, the Koc and log Koc values of the test material at neutral pH were >4.3 x 10⁵and >5.63, respectively.
The adsorption profile of the substance has been sufficiently characterised in the screening test and further testing would not improve the risk assessment of the 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.
