2-Ethoxyethanol is manufactured by the reaction of ethylene oxide with ethanol.
As with other glycol ethers, 2-ethoxyethanol has the useful property of being able to dissolve chemically diverse compounds. It will dissolve oils, resins, grease, waxes, nitrocellulose, and lacquers.[3] This is an ideal property as a multi-purpose cleaner, and, therefore, 2-ethoxyethanol is used in products such as varnish removers and degreasing solutions.
