The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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).
