Description of key information
In an inherent biodegradability test conducted in accordance with EN ISO 9888 (Zahn-Wellens-Test) succinimide was degraded to 99 % after 4 days. Succinimide is therefore fulffiling the criteria of being inherently biodegradable.
Additional information
900 mg test substance/L (equalling 436 mg/L TOC) was applied. Recirculation sludge from the industrial sewage treatment plant (DSM fine chemicals, Austria) and recirculation sludge from the communal (domestic) sewage treatment plant Welser Heide was used in a ratio of 1:1.
The negative control showed no degradation of the substance. The removal of succinimide was measured by Total Organic Carbon (TOC).
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.
