A glycol ether, Butoxyethanol-2 is a colorless liquid with a sweet odor not dissimilar to ether. Due to its inexpensive manufacturing process and relative lack of volatility, Butoxyethanol-2 is employed in numerous industrial and domestic products as a surfactant. This compound is produced using two different methods: 1.) via either ethoxylation reaction of butanol with ethylene oxide and a catalyst, and 2.) via etherification of butanol with chloroethanol-2. In the early part of the 20th century, butoxyethanol-2 was used to dissolve water-soluble and hydrophobic substances due to its efficacy as a modest surfactant. Commercially, butoxyethanol-2 is primarily used as a paint and surface coating solvent, as well as in cleaning products and certain types of inks. It is also used in a wide variety of other manufactured goods such as acrylic resin, firefighting foam, oil spill dispersants, photographic strip solutions, cosmetics, soaps, dry cleaning solution and whiteboard cleaners to name just a few.
