Description of key information

According to Annex IX, column 2, this study does not need to be conducted if the substance is readily biodegradable. Maleic anhydride hydrolyses rapidly (DT50 = 0.3 min), forming maleic acid. The substance itself and maleic acid are both readily biodegradable. Therefore, further testing on biodegradability and identification of degradation productsi s not required.  

Key value for chemical safety assessment
