Propylene Glycol

Propylene Glycol

Propylene Glycol is a viscous, colorless liquid and organic compound that possesses a faintly sweet taste. It is produced on a large scale and is primarily used in the production of polymers, used as chemical feedstock for building materials and toner for laser printers, but also used in food processing, pharma and in airplane deicing applications. Forty-five percent of propylene glycol produced is used as chemical feedstock for the production of unsaturated polyester resins. Propylene glycol is also used in various edible items such as coffee-based drinks, liquid sweeteners, ice cream, whipped dairy products and soda. Propylene glycol is used in water-based acrylic architectural paints to extend dry time which it accomplishes by preventing the surface from drying due to its slower evaporation rate compared to water. It is miscible with a broad range of solvents, including water, acetone, and chloroform. In general, glycols are non-irritating, have very low volatility and very low toxicity.
