Additional information
In a guideline study, the substance 2-(2-(2-methoxyethoxy)ethoxy)ethanol was found to be readily biodegradable and met the 10 day window. Full degradation occured within 13 days. The biodegradation of 2 -(2 -(2 -methoxy)ethoxy)ethoxyethanol was assessed using a non-adapted domestic sewage innoculum in a freshwater medium. Ready degradation was observed. Since the degradation exceeded 60% within 20 days, the substance meets the criteria for classification as readily biodegradable. However, in this study, the substance did not meet the 10 day window. Based on the results of these studies, this substance meets the criteria to be classified as readily biodegradable.
The result for this substance is considered to be representative of the substance that is the subject of this dossier.
