Test material
- Reference substance name:
- (E)-methyl non-2-enoate
- EC Number:
- 811-711-8
- Cas Number:
- 14952-06-8
- Molecular formula:
- C10H18O2
- IUPAC Name:
- (E)-methyl non-2-enoate
- Test material form:
- liquid
Constituent 1
- Specific details on test material used for the study:
- Beauversate (alternative trade name for Neofolione): Quest Code 556712, Test Substance Code R647
Study design
- Oxygen conditions:
- aerobic
- Inoculum or test system:
- activated sludge (adaptation not specified)
- Details on inoculum:
- The inoculum used was 10% by volume of activated sludge plant secondary effluent, filtered through a Whatman filter paper (541) to remove coarse particulate matter.
- Duration of test (contact time):
- 28 d
- Details on study design:
- The test used was the sealed vessel test which is suitable for determining the ready and ultimate biodegradability of organic substances. The test is conducted in 160ml vessels containing 100ml mineral salts medium inoculated with secondary effluent and the respective test or reference substance.
Results and discussion
% Degradation
- Key result
- Parameter:
- % degradation (O2 consumption)
- Value:
- 85.7
- Sampling time:
- 28 d
Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Interpretation of results:
- readily biodegradable
- Executive summary:
Neofolione undergoes 85.7% biodegradation after 28 days in the test conditions.
Therefore, Neofolione should be regarded as readily biodegradable according to this test.
