Incorez 397 was assessed in a closed bottle test in accordance to OECD guideline 301 D and EU method C.4 VI. The test item was exposed to activated sludge from an aeration tank for 28 days. Under the test conditions the percentage biodegradation of Incorez 397 reached a mean of 5.9 % based on ThODNO3. Thus, Incorez 397 was not ready biodegradable.
