Description of key information
Carbon dioxide evolution test (OECD Guideline 301 B, EU Method C.4-C): 86 % degradation after 28 days, exceeding 60 % degradation within the 10 day window.
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
The key study is a recent study (2002), performed according to actual guidelines.The carbon dioxide evolution from "Dibutylfumarate" reached a maximum of about 86 % after 28 days of incubation. The "10-d window" as defined by the Guideline started at about Day 3. 60 % degradation was exceeded already at about Day 13. According to the Guidelines a substance giving a result greater than 60 % degradation within a 10-d window within 28 days is regarded as "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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
