Description of key information

There are no simulation test data on biodegradation in water for the test substance. It was assumed that this is a negligible removal mechanism.

Key value for chemical safety assessment

Additional information

The test substances of the methylenediphenyl isocyanate (MDI) category react quickly with water and hence will be rapidly hydrolysed in contact with aqueous media (T1/2 = 20h). As a result, biodegradation of the hydrolysis products would be measured.
