Description of key information

The substance is readily biodegradable

Key value for chemical safety assessment

Additional information

In a CO2-Evolution Test according to OECD 301B the biodegradation was investigated [BASF SE, 2009]. After 28 days 70-80 % degradation of the substance was determined. Therefore, the pass level for ready biodegradability was reached. Otherwise the criterion of the 10-day time-window was failed. Degradation of mixtures are characterised by multiphase kinetics. Therefore, the 10 day time-window is disregarded for the evaluation of the readily biodegradability of mixtures and is not deemed necessary for assessing ready biodegradability. Thus, the substance can be considered as readily biodegradable.
