Butyl glycol is also an efficient flow improver for urea, melamine and phenolic stoving finishes.

Butyl glycol is also favoured in many products due to its mild odour.
Butyl glycol acts as a solvent and coupling agent in many waxes, resins, oils and textile dyes, and is regularly used in many industrial, commercial and household cleaning products, where Butyl glycol offers good cleaning power as well as the odour typically associated with such products.

Butyl glycol is an important starting material for a variety of syntheses, being one of the raw materials for the production of butyl glycol acetate and for the production of plasticizers by reaction with phthalic anhydride.
Butyl glycol is also formulated into insecticides, herbicides, agricultural pesticides and cosmetic products, and is a component in hydraulic fluids and cutting and drilling oils.

Butyl glycol usage is dominated by the paint industry which consumes approximately 75 % of all the BG produced.

In the petroleum industry
Butyl glycol is commonly produced for the oil industry because of its surfactant properties.[
In the petroleum industry, Butyl glycol 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 Butyl glycol is used to stabilize them by lowering the surface tension.
As a surfactant, Butyl glycol absorbs at the oil-water interface of the fracture.
The compound is also used to facilitate the release of the gas by preventing congealing.
Butyl glycol is also used as a crude oil–water coupling solvent for more general oil well workovers.
Because of its surfactant properties, Butyl glycol 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.

Health Hazard
Butyl glycol is present in a variety of consumer products, including cleaning agents and surface coatings, such as paints, lacquers, and varnishes.
Butyl glycol is readily absorbed following inhalation, oral, and dermal exposure.
Butyl glycol is released into air or water by different industrial activities and facilities that manu facture, process, or use the chemical.
Exposure to Butyl glycol causes irritating effects to the eyes and skin, but it has not induced skin sensitization in guinea pigs.
Information on the human health effects associated with exposure to Butyl glycol is limited.
However, case studies of individuals who had attempted suicide by ingest ing Butyl glycol containing cleaning solutions suffered poisoning with symp toms such as hemoglobinuri , erythropenia, and hypotension, metabolic acidosis, shock, non-cardiogenic pulmonary edema, and albuminuria, hepatic disorders and hematuria.

Production
Butyl glycol is commonly obtained through two processes; the ethoxylation reaction of butanol and ethylene oxide in the presence of a catalyst:

C2H4O + C4H9OH → C4H9OC2H4OH
or the etherification of butanol with 2-chloroethanol.
Butyl glycol can be obtained in the laboratory by performing a ring opening of 2-propyl-1,3-dioxolane with boron trichloride.
Butyl glycol is often produced industrially by combining ethylene glycol and butyraldehyde in a Parr reactor with palladium on carbon.

In 2006, the European production of butyl glycol ethers amounted to 181 kilotons, of which approximately 50% (90 kt/a) was Butyl glycol.
World production is estimated to be 200 to 500 kt/a, of which 75% is for paints and coatings and 18% for metal cleaners and household cleaners.
In the US, Butyl glycol is considered a high production volume chemical because more than 100 million pounds of this chemical are produced per year.
