Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Biodegradation: 0% (28-days) not readily biodegradable, OECD301D, Akzo Nobel 2015
Key value for chemical safety assessment
Additional information
In order to assess the biotic degradation, a ready biodegradability screening test was performed which allows the biodegradability to be measured in an aerobic aqueous medium. The ready biodegradability was determined in the Closed Bottle test (OECD TG 301 D) performed according to slightly modified OECD, EU and ISO Test Guidelines but without parallel positive or toxicity controls in a limited screening study using activated sludge and river water as inocula. The study was extended in accordance with established inherent biodegradation determination literature methodology. 0% degradation was observed at 28 days. The biodegradation did not increase after day 28. The test substance can therefore not be classified as readily biodegradable.
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.
