Description of key information
Readily but failing 10 day window: 71% (CO2 evolution) in 28 days (OECD 301B)
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable but failing 10-day window
Additional information
One study investigating the ready biodegradability of Ditetradecyl fumarate (CAS 10341-03-4) is available. The GLP study was conducted according to OECD 301B under aerobic conditions using non-adapted activated sludge as inoculum (Schwarz, 2012). An initial test concentration of 20 mg/L (TOC) was applied. Based on CO2 evolution a mean degradation of 71% was observed after 28 days. The 10-day window was not passed. Hence, the substance is not readily biodegradable according to OECD criteria. Nevertheless, as the overall pass level of 60% CO2 evolution for an OECD 301B test was passed within the 28 day exposure period, the substance is determined to be “readily biodegradable, but failing 10 day window”. In addition, the test was enhanced up to 60 days with the result of 90% biodegradation. Hence, Ditetradecyl fumarate (CAS 10341-03-4) will not be persistent in the environment.
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
