Biodegradation in water:
readily biodegradable

Additional information

In order to evaluate the biodegradability of the test substance, a study according to OECD guideline OECD 301B was performed by BASF (22G0030/10G009, 2010). Non-adapted sewage sludge from a STP treating mainly domestic waste-waters was applied as inoculum. After 28 days the substance was degraded at an amount of 80-90% CO2/ThCO2. The 10-day window of 60% was met. Thus the test substance is considered readily biodegradable under the conditions of this test.
