Description of key information

Propylene oxide was found ready biodegradable (89% after 28 days) under aerobic conditions in a modified MITI test (MITI 1988).

Key value for chemical safety assessment

Biodegradation in water:
readily biodegradable

Additional information

Propylene oxide was found ready biodegradable (89% after 28 days) under aerobic conditions in a modified MITI test (MITI 1988). Propylene oxide is not readily biodegradable under the stringent conditions of a closed bottle biodegradation test ( Shell Research Ltd., 1985). The available studies indicate that in general propylene oxide can assumed to be ready biodegradable, but under certain stringent conditions this may not be the case.
