Dipropylene glycol monobutyl ether

Dipropylene glycol monobutyl ether (CAS 29911-28-2 ), commonly abbreviated as DPNB, is a slow-evaporating glycol ether solvent used across coatings, cleaning, and personal care formulations.

Its controlled evaporation rate and compatibility with both water-based and solvent-based systems make it a practical choice for formulators managing film formation and flow behavior.

In architectural and industrial coatings, DPNB functions as a coalescing agent and flow promoter, improving film leveling and reducing surface defects in waterborne systems.

Adhesive and sealant manufacturers incorporate it to adjust open time and enhance substrate wetting in both solvent-borne and water-based formulations for industrial use.

Printing ink producers use DPNB to control viscosity and drying profiles in packaging inks, particularly where extended wet time is required on press for high quality results.

Personal care formulators include it as a solvent and coupling agent in products such as hair care treatments and skin cleansers, where it aids ingredient solubilization.

Dipropylene glycol monobutyl ether is supplied as a clear liquid in drum and IBC quantities, with bulk tanker options available for high-volume buyers in the chemical sector.

It is offered primarily in technical and industrial grades, with purity specifications typically at 98% or higher depending on the specific supplier and manufacturing process.
