Description of key information
C16 TMAC was readily biodegradable in an OECD guideline study.
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
A guideline study was conducted to determine the ready biodegradability of C16 TMAC according to the CO2-evolution test method (modified Sturm test). Sodium acetate was used as a functional control to check the activity of the test system. The control achieved 60% biodegradation after 10 days. The toxicity control, containing both the test and the reference substance, achieved 43% biodegradation within 14 days. The test substance in the toxicity control did not inhibit biodegradation of the reference substance. With C16 TMAC, the 10% level (beginning of biodegradation) was reached by one replicate after 7 days and the pass level of 60% was reached after 17 days. The other replicate reached the 10% level after 12 days and 60% after 19 days. Within 28 days 92 and 95% biodegradation was observed in the two replicate samples, mean biodegradation was 93.5%. Under the test conditions, the substance was readily biodegradable
