Description of key information
Based on a weight-of-evidence approach with two inherent biodegradability tests and several BOD5/COD determinations, the test substance can be considered inherently biodegradable. The substance is not readily biodegradable according to CLP criteria.
Key value for chemical safety assessment
- Biodegradation in water:
- inherently biodegradable
