Product Description

Ropylen e glycol (IUPAC name: propane-1,2-diol) is a viscous, colorless liquid, which is nearly odorless but possesses a faintly sweet taste. Industrially, propylen e glycol is mainly produced from propylen e oxide (for food-grade use).
Forty-five percent of propylen e glycol produced is used as a chemical feedstock for the production of unsaturated polyester resins. In this regard, propylen e glycol reacts with a mixture of unsaturated maleic anhydrid e and isophthalic acid to give a copolymer. This partially unsaturated polymer undergoes further crosslinking to yield thermoset plastics. Related to this application, propylen e glycol reacts with propylen e oxide to give oligomers and polymers that are used to produce polyurethanes. Propylen e 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.
Propylen e glycol is also used in various edible items such as coffee-based drinks, liquid sweeteners, ice cream, whipped dairy products and soda. Vaporizers used for delivery of pharmaceuticals or personal-care products often include propylen e glycol among the ingredients.  In alcohol-based hand sanitizers, it is used as a humectant to prevent the skin from drying. Propylen e glycol is used as a solvent in many pharmaceuticals, including oral, injectable, and topical formulations. Many pharmaceutical drugs which are insoluble in water utilize propylen e glycol as a solvent and carrier; benzodiazepin e tablets are one example.  Propylen e glycol is also used as a solvent and carrier for many pharmaceutical capsule preparations. Additionally, certain formulations of artificial tears use propylen e glycol as an ingredient.
