Butyl Cellosolve (IUPAC name: 2-Butoxyethan-1-ol) is a colorless organic chemical with a sweet, ether-like odor, as it derives from the family of glycol ethers, and is a butyl ether of ethylene glycol. As a relatively non-volatile, inexpensive solvent of low toxicity, it is used in many domestic and industrial products because of its properties as a surfactant.
