The ready biodegradability of IFF 09-0035 was investigated in two studies conducted in accordance with OECD TG 301D and 301F, respectively, under GLP. In OECD 301D the concentrations tested were 1 and 3 mg/L test substance. The test substance biodegraded for 25% at 1 mg/L and for 40% at 3 mg/L within 28 days. The substance was not toxic to the inoculum (40% biodegradation in the toxicity control after 14 days). In OECD 301F the concentration tested was 32 mg/L test substance. Under the test conditions, 42.13% biodegradation was seen after day 28. The substance was not toxic to the inoculum (52% biodegradation in the toxicity control after 14 days).

Overall although substantial biodegradation was recorded after 28 days of incubation, IFF 09-0035 was not readily biodegradable under the conditions of the closed bottle test or manometric respirometry test.
