Description of key information

The test item Ukanol FR 70 was tested using a concentration of nominally 20 mg organic carbon/L (corresponding to 34.1 mg Ukanol FR 70/L) in test medium following OECD 301B and EU-Method C.4-C. Aniline was chosen as positive control. Activated sludge was used as inoculum (concentration in the test 25 mg dry matter/L). The test was left running for 28 days. All validity criteria were met. Degradation of the positive control was 66 % after eleven days. The following data were determined for the test item Ukanol FR 70: 10-day-window: not detected

degradation at the end of 10-day-window: none

degradation at the end of the test: 4 %

pass level following guideline: 60% at the end of 10-day-window

Therefore, regardless of the 10-day-window, Ukanol FR 70 is not readily biodegradable following OECD 301B/EU C.4-C.
