Biodegradation in water:
under test conditions no biodegradation observed

Additional information

Key study: A closed bottle test was performed in order to assess the ready biodegradability of OS-2200. The study was conducted in accordance with EU method C.4 -E and OECD 301D under GLP conditions. OS-2200 attained 4% biodegradation within 28 days. Sodium benzoate, the reference substance attained 85% biodegradation within 28 days. Therefore, OS-2200 may not be termed as readily biodegradable.
