If 2 -(2 -methoxyethoxy)ethanol is present in ambient air, it is expected to exist almost entirely in the vapour phase. This substance is not expected to absorb UV light in the environmentally significant range of >290 nm and is not therefore expected to undergo direct photolysis on sunlit soil surfaces, in the atmosphere or in aquatic environments. However, modelling predicts that it is likely to undergo indirect photolysis through hydroxyl radical reaction at a reasonably fast rate, with an estimated half life of 4.9 hours (0.41 days) at an OH concentration of 1.5million OH/cm3 and a 12 hour day). Based on its chemical structure, the substance is expected to be hydrolytically stable under normal environmental conditions.
