Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Not readily biodegradable: 0% after 28 d (O2 consumption, OECD 301 D)
Key value for chemical safety assessment
- Biodegradation in water:
- under test conditions no biodegradation observed
Additional information
One experimental study was performed according to the OECD 301 D (GLP). A filtrate of activated sludge from a domestic sewage treatment plant was used as inoculum. 0% degradation of the test substance was recorded based on O2-consumption after 28 d. Thus, the test substance is not readily biodegradable according to the OECD criteria. A toxicity control containing both, reference substance and test substance, did not indicate inhibitory effects of the test substance to the inoculum (31% degradation after 14 d; trigger value of 25% biodegradation in the toxicity control was reached).
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.
