EC number: 203-051-9
CAS number: 102-76-1
Readily biodegradable: 76-82% (CO2 evolution) after 28 d (OECD 301B)
Three studies investigating the ready biodegradability of
triacetin (CAS 102-76-1) according to OECD guideline 301B (CO2 Evolution
Test) are available. In all three studies domestic activated sludge was
used as inoculum and two concentrations of the test substance were
tested (10 and 20 mg/L). Hales (1993) observed a degradation of
triacetin of more than 76% after 29 days. The 10-day-window was reached
for both test substance concentrations and therewith the test substance
is readily biodegradable. In the two other studies (Coenen (1990) and
Bogers (1988)) a degradation of > 60% within 28 days was recorded as
well. However, the 10-day-window was not reached for the lower test
substance concentration of 10 mg/L and therewith the tests did not
fulfil the criteria for ready biodegradability but failing the 10-day
window. Thus, triacetin can be regarded as readily biodegradable under
test conditions according to OECD criteria.
