Description of key information

Oxybenzone is considered biodegradable.

Key value for chemical safety assessment

Biodegradation in water:
readily biodegradable but failing 10-day window

Additional information

In a manometric-respiratory test performed with oxybenzone, 62% biodegradation was observed within 28 days, but the 10day-window was failed. Thus, the substance cannot be considered as readily biodegradable, but as (inherently) biodegradable.
