Description of key information
OECD Guideline 301F, EU Method C.4-D, GLP, key study, validity 2:
90% biodegradation after 28 days, satisfied the 10d window validation criterion.
Readily biodegradable.
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
For evaluating the biodegradation of the test substance, two valid studies performed according to the OECD Guidelines were available to assess the biodegradation in water of which one can be considered as the key study.
The key study was performed according to the OECD Guideline 301F and EU Method C.4 -D with GLP statement. No inhibitory effects of the test substance to sewage sludge microorganisms were observed (at 100 mg/L). The biodegradation of the test substance was found to be 90% after 28 days and satisfied the 10d window validation criterion. The test substance can be considered as readily biodegradable.
The other study was performed according to the OECD Guideline 301D and supports the conclusion above (79% after 28 days).
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.
