Results and discussion
% Degradation
- Key result
- Parameter:
- % degradation (O2 consumption)
- Value:
- > 62
- St. dev.:
- 3.13
- Sampling time:
- 28 d
- Details on results:
- Based on ThOD NH4 , the degradation rate of the test item “EPALINE 100 - CORN OIL PEROXIDISED”did not reach 60% within the 10-Day window (40.15% on Day 13) but after 28 days of incubation (62.07%).
Under conditions of OECD Guideline 301F, the test item “EPALINE 100 - CORN OIL PEROXIDISED” reach 62.07% after 28 days of incubation and can be considered readily biodegradable based on ThOD NH4 , therefore the 10 Day window failed.
Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Interpretation of results:
- readily biodegradable
- Conclusions:
- Under conditions of OECD Guideline 301F, the test item “EPALINE 100 - CORN OIL PEROXIDISED” reach 62.07% after 28 days of incubation and can be considered readily biodegradable based on ThOD NH4.
