Description of key information

The registered substance is a highly reactive dianhydride hydrolyzing in water within approx. 20 minutes. Testing of the substance as such was not possible, therefore the corresponding Pyromellitic acid PMA was tested (read-across):

Biodegradation in water

The test material PMA attained 100% degradation after 28 days and satisfied the 10-Day window validation criterion, whereby 60% degradation must be attained within 10 days of the degradation exceeding 10%. The test material can therefore be considered to be readily biodegradable under the strict terms and conditions of OECD Guideline No 301B.
