Description of key information
Succinic acid is readily biodegradable.
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
The ready biodegradability of succinic acid was determined using OECD guideline 301E and EU Method C.4-B.
The test substance, succinic acid, with a nominal starting concentration of 20 mg DOC/L was degraded by 96.6 % after 28 days of incubation at a mean temperature of 21.6 °C. The "10-d window" as defined by the guidelines started at approximately Day 1. 70 % degradation was exceeded at about Day 4.
According to the guideline, succinic acid is 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.
