Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
In a GLP study performed according to OECD TG 121 and EC Method C.19, the adsorption coefficient of the test item was determined to be <17.8 (log Koc <1.25) for 19.7% of the test item and greater than 4.3E05 (log Koc >5.63) for 80.3% of the test item by percentage area normalization.
Key value for chemical safety assessment
Additional information
One study is available. In this study, performed under GLP according to OECD TG 121 and EC Method C.19, the adsorption coefficient of the test item was measured using the HPLC screening method. The main components of the test item had no dissociation constants within the environmentally relevant pH range and therefore, the test item was tested with an approximately neutral mobile phase. The sample was prepared in tetrahydrofuran. The adsorption coefficient of the test item has been determined to be <17.8 (log Koc <1.25) for 19.7% of the test item and greater than 4.3E05 (log Koc >5.63) for 80.3% of the test item by percentage area normalization.
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.
