- Details on results:
- Points of degradation plot (test substance):
20.5 % degradation after 5 d
23.9 % degradation after 14 d
41 % degradation after 21 d
37.5 % degradation after 28 d

- other: not readily biodegradable
- Conclusions:
- Degradation = 37% (after 28 days)
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
