propylénglikolt

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

The compound has a wide array of applications due to its humectant, solvent, and preservative properties. In the food industry, it is used as a food additive (E1520) to absorb extra water and maintain moisture, and as a solvent for flavors and colors. In pharmaceuticals, it serves as a solvent for oral, injectable, and topical medications. It is also a common ingredient in cosmetics and personal care products such as moisturizers, lotions, and shampoos, where it helps to retain moisture.

In industrial settings, propylénglikol is utilized in the manufacturing of unsaturated polyester resins, as a component in hydraulic fluids, and as an antifreeze agent, particularly in applications where toxicity is a concern, such as in food processing equipment or environmentally sensitive areas. It is generally recognized as safe (GRAS) by the U.S. Food and Drug Administration (FDA) for use in food, though certain concentrations and applications may have specific regulatory guidelines. While widely used and considered safe for most applications, exposure to very high concentrations can cause irritation.
