- Test temperature: 20-25º C
- pH: 7.4±0.5
- pH adjusted: yes
- Aeration of dilution water: CO2 free air was pumped throgh the flasks continually
- Continuous darkness: yes
TEST SYSTEM
- Culturing apparatus: Glass flasks
- Number of culture flasks/concentration: 2 flasks for each blank, teference and test flask. (8 flasks total)
- Method used to create aerobic conditions: CO2 free air was pumped continously through the flasks
- Test performed in open system: No
- Details of trap for CO2 : 160 ml square bottles containing 100 ml of 0.0125 M Ba(OH)2 were attached to the test flasks.
SAMPLING
- Sampling frequency: Samples were taken on days 2, 3, 4, 5, 6, 7, 8, 9, 11, 12, 14, 15, 19, 25, 26, and 27.
- Sampling method: The Ba(OH)2 was titrated against 0.05NHCl to measure the amount of CO2 evolved. on Day 27 ll test flasks were acidified using NHCl The flasks were then aerated for a further 24 hours. All remaining Ba(OH)2 was then removed for titration on day 28.
- Reference substance:
- aniline
- Parameter:
- % degradation (CO2 evolution)
- Value:
- ca. 90.4
- Sampling time:
- 28 d
- Parameter:
- % degradation (CO2 evolution)
- Value:
- ca. 69.34
- Sampling time:
- 12 d
- Remarks on result:
- other: This was the end of the 10 day window started on day 2. As SCMI produced CO2 equal to more than 60% of its CO2 then it can be considered readily biodegradable
- Results with reference substance:
- The results for distilled aniline showed that on day 15 the mean biodegradation was 73.52% therefore the test was considered valid.
- Validity criteria fulfilled:
- yes
- Interpretation of results:
- readily biodegradable
- Conclusions:
- In a study performed according to OECD 301B, SCMI is readily biodegradable (90.4% in 28d)

Description of key information
In a study performed according to OECD 301B, the registered substance SCMI is readily biodegradable (90.4% in 28d). As the substance is a complex mixture whereby sequential degradation of constituents is expected, the 10d window does not apply. However, the substance did actually meet the 10d window criterion.
In a study performed according to OECD 301B, the read-across analogue SLMI is readily biodegradable (83.9% in 28d) and passes the 10day window.
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
- Type of water:
- freshwater
Additional information
Two key studies have been performed to satisfy the ready biodegradability data requirement for SCMI. The first study was performed on SCMI itself and resulted in a biodegradability of 90.4% after 28 days.
The second study was performed on the read-across substance SLMI (Rodrigue. 2007) which achieved 83.9% biodegradation after 28d.
