The formula



Butyl Glycol Acetate (also known as 2-butoxyethyl acetate; ethylene glycol butyl ether acetate; and 2-butoxyethanol acetate) has the chemical formula C8H16O3, and is a clear, colourless to pale yellow liquid. It has a mild and pleasant ester odour and is only sparingly soluble in water but is miscible with many common organic solvents, for example, alcohols, ketones, aldehydes, ethers, glycols, and glycol ethers. It is this solvent power, combined with its’ low volatility, that sees Butyl Glycol Acetate employed in many branches of industry.
