Description
Dipropylene glycol monobutyl ether (DPnB) is a glycol ether solvent supplied under trade names including Dowanol DPnB, Celtol DPNB, Solvenon DPnB, Butyl Propasol, and Arcosolv DPNB. Assigned CAS 29911-28-2 and EC 249-951-5, it carries no E-code designation. It is classified under HS code 29094990 for customs purposes.
In waterborne coatings, DPnB acts as a coalescing agent, lowering the minimum film-formation temperature and improving surface leveling without raising VOC content disproportionately. In adhesive and sealant formulations, it functions as a reactive diluent and crosslinking aid, controlling viscosity while participating in cure chemistry. Personal care formulators use it as a carrier solvent to solubilize fragrance compounds and condition skin feel.
DPnB is registered under REACH and available in standard industrial grades. Typical packaging includes 200 L drums and IBC totes, with bulk delivery available on request. Buyers should confirm grade specifications against internal quality standards, as no Ph.Eur. or FCC monograph applies to this substance.
