Uses OF Ethylene Glycol Monobutyl Ether
Ethylene Glycol Monobutyl Ether is a glycol ether with modest surfactant properties, which can also be used as a mutual solvent.

Commercial uses OF Ethylene Glycol Monobutyl Ether
Ethylene Glycol Monobutyl Ether is a solvent for paints and surface coatings, as well as cleaning products and inks.
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 and glass cleaners, liquid soaps, cosmetics, dry cleaning solutions, lacquers, varnishes, herbicides, latex paints, enamels, printing paste, and varnish removers, and silicone caulk.

FDA to be used as direct and indirect food additives, which include antimicrobial agents, defoamers, stabilizers, and adhesives.

In the petroleum industry
Ethylene Glycol Monobutyl Ether is commonly produced for the oil industry because of its surfactant properties.

In the petroleum industry, Ethylene Glycol Monobutyl Ether is a component of fracturing fluids, drilling 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 Ethylene Glycol Monobutyl Ether is used to stabilize them by lowering the surface tension. 
As a surfactant, Ethylene Glycol Monobutyl Ether adsorbs at the oil-water interface of the fracture. 
Ethylene Glycol Monobutyl Ether is also used to facilitate the release of the gas by preventing congealing. 
Ethylene Glycol Monobutyl Ether is also used as a crude oil–water coupling solvent for more general oil well workovers. 
Because of its surfactant properties, Ethylene Glycol Monobutyl Ether 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.
