Additional information

The test on ready biodegradability in water (key_ready biodegradability_2013_Rel1) of the test item performed according to OECD 310 and GLP was rated with RL=1 (reliable without restrictions) and used as key study. The substance is readily biodegradable, since the pass level of 60% degradation was reached in a 10 d-window within the 28 days period of the test. In the toxicity control, containing test and reference item, a biodegradation of 66 % was determined after 28 days. The biodegradation of the reference item was not inhibited by the test item in the toxicity control, thus the test substance is not inhibitory to microorganisms at a tested concentration of 23 mg/L.

The test item is classified as readily biodegradable as the pass level of 60% degradation was reached in a 10 d-window within the 28 day period of the test and is expected to undergo rapid biodegradation and to be non-persistent in the aquatic environment.
