Description of key information

The substance is not biodegradable (< 6% after 28 days) as shown in the ready biodegradability test.

Key value for chemical safety assessment

Biodegradation in water:
under test conditions no biodegradation observed

Additional information

The study was performed according to OECD guideline 301B. The relative degradation values calculated from the measurements performed during the test period revealed no significant degradation of the substance at both concentrations (< 6% within 28 days). Since the substance was hardly soluble in water, the lack of microbial degradation was a consequence of the limited availability of the substance for micro-organisms.
