Butyl di glycol (also known as BDG, butyl dioxitol, diethylene glycol monobutyl ether, 2(-2butoxyethoxy) ethanol and butoxydiethylene glycol) is a colourless, clear organic compound with a faint characteristic odour that has the formula C8H18O3. It is soluble in water and miscible with many common solvents, and also has low volatility and a high boiling point. These are the factors that make butyl di glycol most useful in the paint industry.
