- 28 d
Results and discussion
% Degradation
- Parameter:
- % degradation (CO2 evolution)
- Value:
- >= 3.7 - <= 7.7
- Sampling time:
- 28 d
- Details on results:
- Under the test conditions the percentage biodegradation of AGEE 623 Amidester was determined to be -5.6 % and 1.2 % after 28 days of incubation.
After determination of residual CO2 in the test flasks on day 29 biodegradation rates of 3.7 % and 7.7 % were determined.
Applicant's summary and conclusion
- Interpretation of results:
- under test conditions no biodegradation observed
- Conclusions:
- The test substance can not considered to be ready biodegradable.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
