Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
- Biodegradation in water:
- under test conditions no biodegradation observed
Additional information
The biodegradability of the substance was examined in a screening study according to OECD Guideline 310 (Headspace test) and compliant with GLP criteria (BASF, 2013). In this study biodegradation potential was determined by measurement of the total inorganic Carbon (TIC) formed by mineralization of the organic carbon (TOC) of ca. 30 mg/L test compound when exposed to activated sludge from a municipal sewage plant for 28 days. The degree of biodegradation after the 28-day exposure period was 1 ± 1 % TIC/TOC (mean value of five test assays). Based on these findings the test substance was evaluated as poorly 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.
