Description of key information

The test substance was not readily biodegradable under the conditions of this test. The required pass level for ready biodegradability within a ten days window was not reached.

Key value for chemical safety assessment

Biodegradation in water:
under test conditions no biodegradation observed

Additional information

A CO2-evolution test according to OECD guideline 301B was performed in order to evaluate aerobic elimination and degradation potential of the test item (BASF 22G0495/14G366, 2015). An initial test concentration of 10 mg/L TOC nominal (corresponding to 15 mg/L test substance) was applied.

After an exposure period of 28 days the determined degree of degradation was 0 -10 % CO2/ThCO2 in this test. Therefore, the test substance is not regarded as readily biodegradable under the conditions of this test. The required pass level for ready biodegradability within ten days window was not reached.
