Description of key information

In a closed bottle test the test item showed 69 % biodegradation after 28 days, therefore it was considered to be readily biodegradable.

Key value for chemical safety assessment

Biodegradation in water:
readily biodegradable

Additional information

The test substance in a mineral medium was inoculated with secondary effluent and incubated for 28 d under aerobic conditions in closed bottles (OECD 301 D). Based on determination of the content of dissolved oxygen (amount of oxygen taken up by the test chemical), the test substance was found to be readily biodegradable.
