Administrative data
Link to relevant study record(s)
Description of key information
The substance is readily biodegradable as observed in a DOC Die Away test according to OECD TG 301 A.
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
- Type of water:
- freshwater
Additional information
The biodegradation potential of the substance in water was determined in a screening study according to OECD TG 301A (DOC Die Away Test) and in compliance with GLP criteria (BASF AG, 1999). In this study 20 mg/L test substance (expressed as DOC) was inoculated with non-adapted activated sludge from a domestic sewage treatment plant for 15 days under aerobic conditions. After 10 days degradation was 93%. After the 15-day incubation period the substance was biodegraded almost completely (90 - 100%). Based on these results the substance can 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.
