Description
Propylene Glycol Monopropyl Ether (CAS 1569-01-3), commonly abbreviated as PNP, is a glycol ether solvent supplied under trade names including Dowanol PNP, Arcosolv PNP, and Propasol Solvent P. It carries no E-code designation and is classified under HS code 29094990.
In industrial cleaning formulations, PNP solubilises oils, greases, and resinous soils by disrupting their surface adhesion, making it effective in hard-surface and automotive degreasers. In coatings and printing inks, it controls evaporation rate and improves resin compatibility, reducing film defects such as blushing and cratering during application.
PNP is available in standard industrial and technical grades and is subject to REACH registration requirements within the EU. It is typically supplied in drums and IBC containers. Procurement teams should confirm SDS compliance and regional VOC classification before specifying for cleaning or coating end-uses.
