2-Ethoxyethanol is a diluent in colour additive mixtures for marking food. 2-Ethoxyethanol, also known by the trademark Cellosolve or ethyl cellosolve, is a solvent used widely in commercial and industrial applications. It is a clear, colorless, nearly odorless liquid that is miscible with water, ethanol, diethyl ether, acetone, and ethyl acetate. 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. 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. 2-Ethoxyethanol belongs to the family of Primary Alcohols. These are compounds comprising the primary alcohol functional group, with the general strucuture RCOH (R=alkyl, aryl).
