- % degradation (O2 consumption)
- Value:
- 0
- Sampling time:
- 28 d
- Details on results:
- Based on ThOD, the 10-day window failed and the degradation rate of the test item is zero after 28 days of incubation.
Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Interpretation of results:
- under test conditions no biodegradation observed
- Conclusions:
- The biodegradation potential of the test item was performed according to OECD 301F guideline. The resultas obtained show that the degradation rate of the test item is zero after 28 days of incubation. Under the experimental conditions, the test item is not considered to be biodegradable.
- Executive summary:
The biodegradation potential of the test item was performed according to OECD 301F guideline. The resultas obtained show that the degradation rate of the test item is zero after 28 days of incubation. Under the experimental conditions, the test item is not considered to be biodegradable.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
