Description of key information

No ready biodegradation (0% degradation within 28 days) was observed in a manometric respiratory test performed with domestic, non-adapted activated sludge according to Directive 92/69/EEC, C.4-D (Bayer AG, 2000). A DOC-DIE Away test (EU method C.4 A) that was conducted with isophorone diamine indicates that the hydrolysis product is not readily biodegradable either.

Key value for chemical safety assessment

Biodegradation in water:
under test conditions no biodegradation observed
