Description of key information

Ready biodegradability: readily biodegradable but failing the 10-day window criterion for the test.

Key value for chemical safety assessment

Biodegradation in water:
readily biodegradable but failing 10-day window

Additional information

Ready biodegradability has been investigated in a DOC-die away test according to EU test methods. Tetrahydrophthalic anhydride was found to be readily biodegradable but failed to meet the 10-day window criterion for the test.
