Description of key information
Determination of 'Ready' Biodegradability: Carbon Dioxide (CO2) Evolution Test (Modified Sturm Test). The study was performed without GLP in a lab which uses to operate under GLP. The study protocol was according to OECD Guideline 301 and EEC method C.4-Cfrom Directive 92/69. No major deviations noted.
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable but failing 10-day window
Additional information
The test material was tested for its readily biodegradability in the CO2Evolution Test (Modified Sturm Test) at ca. 39 mg / 2L, corresponding to approx 12 mg TOC / L. The relative degradation values calculated from the measurement of the CO2formation during the test period of 28 days revealed no significant degradation of the test material. The substance was found not readily biodegradable.The toxicity test showed that there is no inhibition of the degradation of sodium acetate by the test substance.
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.
