Diethylene glycol monobutyl ether

Diethylene glycol monobutyl ether, commonly known as butyldiglycol or Butyl DIGOL and sold under trade names such as Dowanol DB, is a glycol ether solvent with CAS number 112-34-5 and EC number 203-961-6. It carries no assigned E-code and is classified under HS code 29094300.

In coatings and printing inks, butyldiglycol acts as a coalescing solvent, slowing evaporation to improve film formation and flow on substrate surfaces. In industrial cleaning formulations, its ether-alcohol structure allows it to solubilise both polar and non-polar soils, making it effective in hard-surface degreasers and aqueous cleaning concentrates.

Butyldiglycol is supplied in standard industrial grades compliant with REACH registration requirements. It is available in drum and IBC packaging formats suited to B2B procurement volumes. Buyers should confirm grade specifications against application requirements, particularly where formulation standards or regional chemical regulations apply.
