Glycol ethers, with the combination of ether, alcohol and hydrocarbon chain in one molecule, provide versatile solvency characteristics with both polar and non-polar properties. The chemical structure of long hydrocarbon chain resist to solubility in water, while ether or alcohol groups introduce the promoted hydrophilic solubility performance. This surfactant-like structure provides the compatibility between water and a number of organic solvents, and the ability to couple unlike phases. Glycol ethers are characterized by their wide range of hydrophilic/hydrophobic balances. glycol ethers are used as diluents and levelling agents in the manufacture of paints and baking finishes. Glycol ether series are used in the manufacture of nitrocellulose and combination lacquers. They are used as an additive in brake fluid. They are formulated for dying textiles and leathers and for insecticides and herbicides. They provides performance in cleaners products with oil-water dispersions. They are used in printing industries as they have a slow evaporation rate. They are used as a fixative for perfumes, germicides, bactericides, insect repellents and antiseptic. They are used as an additive for jet fuel to prevent ice buildup. Thje term of cellosolve refers to ethylene glycol monoethyl ether or a group of glycol ether solvent as below.

The term of glyme refers to glycol dimethyl ether. Monoglyme, diglyme, triglyme are ethylene glycol dimethyl ether, Diethylene glycol dimethyl ether, and triethylene glycol dimethyl ether respectively. Ethylene glycol dimethyl ether is readily soluble in water. Glymes, dimethyl ethers, have two terminal methyl groups which offer stability and high solvency. They are used as a higher boiling alternative to diethyl ether or THF. Glyme forms chelate and are useful as bidentate ligands. They are useful as solubilizers and phase transfer catalysts. Glymes offer the property required as an inert reaction medium chemical reaction due to their low chemical reactivity. They are suitable particularly for organometallic and polymerization reactions. Glycol ethers which contain hydroxyl group are also useful chemical intermediate. The hydroxyl group will undergo reaction with aldehydes (or ketones) to produce hemiacetals (or acetals), with epoxides to produce polyether alcohols, with halogenating agents to produce alkoxy alkyl halides, with carboxylic acid compounds or inorganic acids to produce a number of esters.
