Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Ready biodegradation resulting in biodegradation of ca 20% over 15 days, with no further degradation to day 28
Zahn-Wellens study failed to show significant biodegradation, but no evidence of toxicity
Key value for chemical safety assessment
- Biodegradation in water:
- inherently biodegradable, not fulfilling specific criteria
- Type of water:
- freshwater
Additional information
There are limitations in the two test reports cited, but the laboratory work provides sufficient evidence that some biodegradation occurs. However, even with alternative methods, it is unlikely that the substance would be readily biodegradable and repeating the study was not considered at the time of testing.
It is likely that the substance will ultimately biodegrade. EPISuite evaluation suggests inherent biodegradation.
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.
