Justification for data waiving:
the study does not need to be conducted because the substance is readily biodegradable

Description of key information

Diamine methylated does not contain hydrolysable covalent bonds. Cleavage of a carbon-nitrogen bond under environmental conditions is only possible with a carbonyl group adjacent to the nitrogen atom. Degradation of diamines methylated through hydrolysis is therefore not considered.

Key value for chemical safety assessment

Half-life for hydrolysis:
15 yr
at the temperature of:
20 °C
