What is 2-Butoxyethanol Butyl Glycol CAS 111-76-2?

2-Butoxyethanol is a clear, colourless glycol ether with formula C6H14O2 and CAS 111-76-2. It is supplied as a coupling solvent for waterborne coatings, industrial cleaners, inks and related formulations.

Are 2-Butoxyethanol, Butyl Glycol and EGBE the same material?

Yes. They are common names for ethylene glycol monobutyl ether, CAS 111-76-2. It should not be confused with 2-butoxyethyl acetate (CAS 112-07-2) or diethylene glycol monobutyl ether, also called butyldiglycol or Butyl CARBITOL (CAS 112-34-5).

What role does 2-Butoxyethanol play in waterborne formulations?

It acts as a coupling agent between the water phase and the resin or solvent phase, which helps stabilise waterborne paints and cleaning formulations. The use level must match the resin, water, surfactant and drying requirements rather than being used as a universal drop-in solvent.

What are the key physical properties of 2-Butoxyethanol?

It has a boiling point around 168-172 deg C, a density near 0.90 g/cm3 and a freezing point around -70 to -74.8 deg C. It is miscible with water and has a relatively low vapour pressure below 1 mm Hg at 20 deg C.

Which 2-Butoxyethanol specifications should be checked before use?

Confirm purity, colour, water content, acidity and distillation range, including initial boiling point and dry point. Peroxide or inhibitor requirements and relevant impurities should also be matched where the coating, cleaner or process specification calls for them.

Product Description

2-Butoxyethanol (Butyl Glycol) CAS 111-76-2 is ethylene glycol monobutyl ether, with EC 203-905-0 and molecular formula C6H14O2.

Synonyms: 2-Butoxyethanol; Butyl glycol; Ethylene glycol monobutyl ether; EGBE; 2-Butoxy-1-ethanol.

CAS: 111-76-2.

Molecular formula: C6H14O2.

It is supplied as a clear, colourless liquid.

It is positioned as a glycol-ether coupling solvent for waterborne coatings, industrial cleaners and inks.

It is not the same material as butyldiglycol or Butyl CARBITOL, CAS 112-34-5, or 2-butoxyethyl acetate, CAS 112-07-2.

It is used as a compatible glycol-ether co-solvent in waterborne paints and coatings.

It is used in industrial cleaners, degreasers, wax strippers and metal-cleaning formulations.

It is used in printing inks, surface coatings, lacquers, varnishes and selected silicone-caulk systems.

It is also used in industrial-process and chemical-intermediate applications specifying 2-butoxyethanol.

Commercial grades commonly specify a boiling point of about 168-172 C and a density near 0.90 g/cm3.

It is miscible with water, with a freezing point around -70 to -74.8 C and low vapour pressure below 1 mm Hg at 20 C.

Confirm purity, colour, water content, acidity and distillation range, and match peroxide or inhibitor requirements and relevant impurities.

Store in tightly closed containers in a cool, dry, well-ventilated area, away from ignition sources.

Use suitable PPE and vapour control when handling the material to prevent inhalation and skin or eye contact.

Confirm packaging suitable for the liquid form and order quantity, and follow the current SDS.
