Butyl Cellosolve


Available Options


  • 2-Butoxyethanol is a glycol ether with modest surfactant properties (and it can be used as a mutual solvent). In use since the 1930s, glycol ethers are solvents that dissolve both water-soluble and hydrophobic substances. Glycol ethers consist of two components, an alcohol and ether. According to the nature of alcohol, molecules of this class can be divided into two groups: E series and P series which correspond to ethylene and propylene respectively. Glycol ethers are selected for specific purposes, such as solubilityinflammability, and volatility.

Commercial uses

  • 2-Butoxyethanol is a solvent for paints and surface coatings, as well as cleaning products and inks.[6][9] Products that contain 2-butoxyethanol include acrylic resin formulations, asphalt release agents, firefighting foam, leather protectors, oil spill dispersants, degreaser applications, photographic strip solutions, whiteboard cleaners, liquid soapscosmeticsdry cleaning solutions, lacquersvarnishesherbicideslatex paintsenamels, printing paste, and varnish removers, and silicone caulk. Products containing this compound are commonly found at construction sites, automobile repair shops, print shops, and facilities that produce sterilizing and cleaning products. It is the main ingredient of many home, commercial and industrial cleaning solutions. Since the molecule has both non-polar and polar ends, butoxyethanol is useful for removing both polar and non-polar substances, like grease and oils. It is also approved by the U.S. FDA to be used as direct and indirect food additives, which include antimicrobial agents, defoamers, stabilizers, and adhesives.

In the petroleum industry

  • 2-butoxyethanol is commonly produced for the oil industry because of its surfactant properties.
  • In the petroleum industry, 2-butoxyethanol is a component of fracturing fluidsdrilling stabilizers, and oil slick dispersants for both water-based and oil-based hydraulic fracturing When liquid is pumped into the well, the fracturing fluids are pumped under extreme pressure, so 2-butoxyethanol is used to stabilize them by lowering the surface tension.As a surfactant, 2-butoxyethanol adsorbs at the oil-water interface of the fracture. The compound is also used to facilitate the release of the gas by preventing congealing. It is also used as a crude oil-water coupling solvent for more general oil well workovers. Because of its surfactantproperties, it is a major constituent (30–60% w/w) in the oil spill dispersant Corexit 9527, which was widely used in the aftermath of the 2010 Deepwater Horizon oil spill.
