Description of key information
In a study according to OECD test guideline 301B (CO2 evolution test), the test substance was readily biodegradable (meeting the 10-day windows) with 94.2 % biodegradation after 28 days.
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
The biodegradability of the test substance was investigated in a study according to OECD test guideline 301B CO2 evoluation test) under GLP. Under aerobic conditions using domestic, non-adapted activated sludge the CO2 evolution was measured over 28 days.
The test substance was degraded to 94.2% after 28 days, while all acceptance criteria were fulfilled. The 10 -day window was met as on day 4 2.6% degradation was observed and on day 14 70.9%. Therefore, the test substance is considered to be readily biodegradable.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
