Description of key information

Biodegradation in water: screening tests: biodegradation 23% (COD) in 28 days (OECD 301F, EU C.4-D)

Key value for chemical safety assessment

Biodegradation in water:
under test conditions no biodegradation observed

Additional information

Mean oxygen consumption in biotic mixtures containing the test material was equivalent to 10% of the COD value after approximately 5 days and 23% at the end of the test (Day 28). A biodegradation plateau was observed from approximately Day 9.

The results clearly show that the substance can be at least partially biodegraded.
