'''Glycol ethers''' are a group of [[solvent]]s based on [[alkyl]] [[ether]]s of [[ethylene glycol]] commonly used in [[paint]]s. These solvents typically have higher boiling point, together with the favorable solvent properties of lower molecular weight ethers and [[alcohol]]s. Glycol ethers are also sometimes called by the trade name Cellosolve, with the original being [[ethyl cellosolve]] (ethylene glycol monoethyl ether).
Glycol ethers can be also derived of [[diethylene glycol]] ([[carbitol]]s). [[Acetate]]s of glycols are a similar kind of potent solvents.
Recent study suggests that occupational exposure to glycol ethers is related to low motile sperm count in men.<ref>{{cite journal| author=Nicola Cherry, Harry Moore, Roseanne McNamee, Allan Pacey, Gary Burgess, Julie-Ann Clyma, Martin Dippnall, Helen Baillie and Andrew Povey |title=Occupation and male infertility: glycol ethers and other exposures |journal=Occup.
