propylenglykolia

Propylenglykolia, 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. Propylenglykolia is miscible with a broad range of solvents, including water, acetone, and chloroform. Its chemical structure features two hydroxyl groups attached to adjacent carbon atoms, which contributes to its solubility and humectant properties.

Industrially, propylenglykolia is produced through the hydration of propylene oxide. This process yields a mixture of isomers, with propane-1,2-diol being the primary product. Its low toxicity and versatile properties have led to its widespread use in various applications.

In the food industry, it is commonly used as a solvent for flavors and colors, as well as a humectant to retain moisture in processed foods. It is also found in pharmaceuticals as a solvent for oral and topical medications, and in cosmetics and personal care products as a moisturizer and viscosity-decreasing agent. Propylenglykolia serves as a key ingredient in the production of polyester resins and antifreeze solutions. It is also employed in e-cigarette liquids to create vapor. While generally recognized as safe (GRAS) by regulatory bodies for its intended uses, individual sensitivities or excessive consumption can lead to adverse effects.
