Description of key information

Two studies are available:
1) A biodegradation study (Pence, 1987) is available which is key study. This study showed that the test substance was degraded by more than 60% in 27 days but failed the 10-day window..
2) A biodegradation study (Pence, 1989) is available which is key study. This study showed that the test substance is inherently biodegradable.

Key value for chemical safety assessment

Biodegradation in water:
readily biodegradable

Additional information

Based on the results of two different biodegradation tests, the test substance can be considered as rapidly and ultimately biodegradable. Although it failed the 10 -day window in the screening test, the test substance degraded almost completely in the SCAS test within 14 days and > 60% in the Modified screening test after 27 days.
