Description of key information

Within 28 days, a degradation rate of 2 % was determined. HDI oligomers, iminooxadiazindione is considered to be "Not Readily Biodegradable". The reference compound sodium benzoate showed 87 % degradation after 14 days.
Within 27 days no degradation of HDI oligomers, iminooxadiazindione was determined.The reference compound sodium benzoate showed 68 % degradation after 7 days and 67 % degradation after 14 days.

Key value for chemical safety assessment

Biodegradation in water:
under test conditions no biodegradation observed
