Description of key information

Additional information

A number of guideline biodegradation studies have been carried out using unadapted innoculii in freshwater. These clearly indicate that 2 -(2 -butoxyethoxy)ethanol is readily biodegradable. From the information available, a decision on whether the "10 day window" is met is marginal but, on balance, it is concluded that this criteria is just met. There are multiple supporting inherent biodegradation studies that also support the conclusion of degradability. The substance is not likely to be hydrolysed under normal environmental conditions but, as the substance is readily biodegradable, this is of no consequence. As this substance has a low partition coefficient, bioaccumulation is not likely to be significant nor adsorption to soil or sediments. The complete miscibility of the substance in water suggests that volatilization from surface waters is not an important fate processes.
