Description of key information

The substance is not readily biodegradable.   

Key value for chemical safety assessment

Biodegradation in water:
under test conditions no biodegradation observed

Additional information

The test substance attained only 24% degradation within 28 days and cannot, therefore, be considered as readily biodegradable.

Oxygen depletions in the inoculated and non-inoculated control series were within the prescribed limits as follow:

Non-innoculated control;

<0.3 mgO2/l after 5 days and <0.4 mgO2/l after 28 days.

Inoculated control:

<0.5 mgO2/l after 5 days and <0.6 mgO2/l after 28 days.
