Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Biodegradation in water: screening tests
Administrative data
Link to relevant study record(s)
Description of key information
Not readily biodegradable (by OECD criteria).
Key value for chemical safety assessment
Additional information
The ready biodegradability was assessed in a study according to OECD 301 B under consideration of GLP. An initial concentration of 20 mg/L test substance (based on TOC) was used. The inoculum was collected from a municipal sewage treatment plant and was not adapted. After 28d <10% CO2/ThO2 was measured. The subsance cannot be regarded 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.
