Description of key information
Results indicated that none of the streams could be considered readily biodegradable. The biodegradation range was 7.3% (no timeframe) - 29% after 28 days. Information is available for 3 streams in this Category. Proprietary data were available from the American Chemistry Council (Exxon Mobil 2004) for the streams 648513-69-9 and 69013-21-4 and from Elf Atochem (2000) for 64742-90-1. These studies were based on standard guidelines and are considered reliable for assessment. These studies did not show the streams to be readily biodegradable. Data available for these streams will be read across to other category members.
Key value for chemical safety assessment
- Biodegradation in water:
- under test conditions no biodegradation observed
Additional information
