Description of key information

In a closed bottle test the biodegradation was determined to be 75 % 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 ready biodegradability in the Closed Bottle Test was determined with domestic activated sludge for the test item over a period of 28 days according to OECD 301 D. The degradation was followed by measuring the oxygen concentrations. In the 10-d-window a mean biodegradation rate of 66 % was reached. The biodegradation came to a maximum of 75 % after 28 days.The test item must be regarded to be readily biodegradable in the 10-d-window and after 28 days. The test substance was not inhibitory to microorganisms at a tested concentration of 1.75 mg/L.
