Description and Uses

2-Ethoxyethanol is a stable, colorless, flammable liquid, synthetically produced throughout the world. It belongs to a larger group of glycol ether solvents. 2-Ethoxyethanol is commercially referred to as Ethyl Cellosolve or Cellosolve, a trademark registered by Union Carbide in 1924. It was first synthesized to have the same chemical properties of both alcohols and ethers (hydrophilic and lipophilic) but less volatile, which improves production characteristics. The glycol ethers are made by reacting anhydrous alcohols with ethylene oxide.

Ethylene glycol monoethyl ether is used in varnish removers, lacquers, and as a solvent for printing inks, duplicating fluids, and epoxy. Ethylene glycol monobutyl ether is used in hydraulic fluids, as a coupling agent for water-based coatings, in vinyl and acrylic paints and varnishes, and as a solvent for varnishes, enamels, spray lacquers, dry cleaning compounds, textiles, and cosmetics.
