It is also used as a diluent in hydraulic brake fluids.

Frequently Asked Questions

What is diethylene glycol monobutyl ether used for?

Diethylene glycol monobutyl ether (DEGBE, CAS 112-34-5) is a glycol-ether solvent and coalescing agent. It dissolves nitrocellulose, oils, dyes, gums, and polymers, acts as a film-formation aid in latex paints, serves as a coupling solvent in household and industrial cleaners and metalworking fluids, and is used as a diluent in hydraulic brake fluids. RawSource supplies it in bulk to coatings and cleaning formulators.

What is another name for diethylene glycol monobutyl ether?

DEGBE is also known as butyl carbitol, 2-(2-butoxyethoxy)ethanol, and diethylene glycol n-butyl ether. Its CAS number is 112-34-5 and formula C8H18O3.

Is diethylene glycol monobutyl ether water soluble?

Yes. DEGBE is miscible with water and with a wide range of organic solvents, which is what makes it effective as a coupling and mutual solvent in waterborne cleaners and latex paint systems. This dual solubility lets it bridge oil- and water-phase components in a formulation.

What is the CAS number for diethylene glycol monobutyl ether?

DEGBE's CAS number is 112-34-5, formula C8H18O3, classified under HS 2909.43 (monobutyl ethers of ethylene or diethylene glycol). RawSource provides a Certificate of Analysis and SDS per shipment.

What is the cost of bulk diethylene glycol monobutyl ether?

Bulk DEGBE pricing depends on volume, packaging, and freight. RawSource supplies it in drums, totes, and bulk; request a bulk quote with your volume and ship-to for current pricing.
