- readily biodegradable
Additional information
A study was performed to determine the potential for biodegradation of the substance in water by the CO2 evolution method based on OECD TG 301B (CO2 evolution). An activated sewage sludge was used. The substance and a reference substance were added to the inoculum at a concentration of 10 mg C/L. A blank control containing inoculum only was run alongside the substance vessels. Test vessels were incubated aerobically in the dark for a period of 28 days at ca. 22°C. Approximately 60% CO2 was evolved by Day 10, with 78.9% biodegradation was observed in 28 days thereby indicating the test material is "readily biodegradable".
The reference substance, sodium benzoate, was considered readily biodegradable under the OECD definition (> 60% CO2 production in 28 days and within a 10-day window of reaching 10% CO2 production). Thus the microbial inoculum for the study was acceptable.
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.
