Propyleniglykoli

Propyleniglykoli, also known as propane-1,2-diol, is a synthetic organic compound with the chemical formula C3H8O2. It is a viscous, colorless liquid that is nearly odorless but possesses a faintly sweet taste. Propyleniglykoli is miscible with water, acetone, and chloroform. It is produced industrially through the hydration of propylene oxide.

This compound serves a wide variety of applications due to its properties as a humectant, solvent, and preservative. It is commonly found in cosmetics, personal care products, and pharmaceuticals, where it helps to retain moisture and improve texture. In the food industry, propyleniglykoli is used as a solvent for flavors and colors, and as a stabilizer in some processed foods. It is also a key ingredient in e-liquids for electronic cigarettes, acting as a carrier for nicotine and flavorings.

In industrial settings, propyleniglykoli is used in antifreeze formulations, de-icing fluids, and as a raw material in the production of unsaturated polyester resins. These resins are then used in the manufacturing of fiberglass-reinforced plastics, coatings, and adhesives. While generally recognized as safe for consumption in small quantities by regulatory bodies like the U.S. Food and Drug Administration, higher concentrations or prolonged exposure can lead to adverse effects.
