Description of key information
TDI-Urone was tested for inherent biodegradability according to the German Guideline DIN EN ISO 9888 which is similar to OECD 302 B (Zahn-Wellens-Test) at an initial concentration of ca. 400 mg DOC/L at temperatures of 20 -25°C for 28 days. Biodegradation was followed by measurements of DOC removal.
Under the conditions of the test, 10 % degradation could be observed, indicating that the substance is only poorly degradable.
The conduct of further studies on biological degradation (surface water, sediment) is not required in view of the negligible environmental hazard of the substance, and the negligible adsorption potential (lack of exposure of sediments).
Additional information
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.
