Description of key information

The test substance Intermediate 36 was examined in a ready biodegradability study in a closed bottle test. Intermediate 36 was considered to be not ready biodegradable.

Key value for chemical safety assessment

Additional information

The ready biodegradability of Intermediate 36 was studied in a closed bottle test. The test item was exposed to activated sludge in the dark at 22.0 - 22.9°C for 28 days. The oxygen measurements were performed in duplicate on days 0, 7, 14, 21 and 28. Intermediate 36 reached a mean of 16.9 % after 28 days based on its COD.
Hence, the test item is considered to be not ready biodegradable.
The study was conducted according to the OECD guideline 301 D and the EU-Guideline C.4 -E.
