DOWANOL™ PnP Glycol Ether

DOWANOL™ PnP glycol ether offers an excellent balance between hydrophilic and hydrophobic properties, and is our most hydrophobic glycol ether that still maintains complete water solubility. DOWANOL™ PnP is primarily used in cleaning products, where its fast evaporation rate and excellent ability to solubilize organic soils makes it useful in a wide variety of formulation systems.

Used in:

  • Household and industrial cleaners, grease and paint removers, metal cleaners, and hard surface cleaners
  • Water-based latex coatings
  • Water-reducible aerosol paint formulations

Advantages:

  • Colorless
  • Low odor
  • Completely water soluble
  • Excellent balance of aqueous and organic solubility
  • Good chemical stability
