Description
Dipropylene glycol n-propyl ether, commonly abbreviated as DPNP and sold under trade names including Dowanol DPnP, Celtol DPNP, and Arcosolv DPNP, is a glycol ether solvent with CAS number 29911-27-1. It carries no assigned E-code and is classified under HS code 29094990 for customs purposes.
In waterborne coatings and industrial cleaners, DPNP functions as a coalescing agent and coupling solvent, reducing surface tension to improve film formation and keeping surfactant-based cleaning formulations stable across dilution ratios. It is also used in electronics cleaning to dissolve flux residues without attacking sensitive substrates, and in printing inks to control viscosity and drying rate.
DPNP is supplied in compliance with REACH regulations and is available in standard industrial drum and IBC packaging. Procurement teams should confirm grade specifications directly with the supplier, as purity levels and residual water content vary between manufacturers.
