Description of key information

Biodegradation in water - manometric respirometry test (OECD 301F; GLP compliant): readily biodegradable (79 % after 28 days). The 10-d window was fulfilled.

Key value for chemical safety assessment

Biodegradation in water:
readily biodegradable

Additional information

One study on biodegradation in water was conducted. A manometric respirometry test (OECD 301F; GLP) was initiated with the test item resulting in 79 % degradation after 28 days (20 mg/L; ThOD 61 mg). The 10-d window was fulfilled (72 % biodegradation (20 mg test substance/L) that starts at day 7/8). As inoculum a non-adapted, domestic, activated sludge was used. The test item is considered to be readily biodegradable under the chosen test conditions.
