Description of key information

The ready biodegradability of the test item was determined with non-adapted activated sludge in the Manometric Respirometry Test for a period of 28 days. The study was conducted according to OECD guideline 301 F and EC D.4-D.

The functional control reached the pass level (degradation > 60%) within 3 days and the maximum of 100 % degradation was reached on day 13.

In the toxicity control containing both test and reference item 47% degradation occurred within 14 days. After 28 days the biodegradation came to 50%.

For the test item the mean biodegradation on day 28 was 2%. The validity criteria of the guideline were fulfilled. The test item is classified as not readily biodegradable within the 28 day period of the study.
