propüleenglükoolil

Propüleenglükoolil, 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. Propüleenglükoolil is miscible with a broad range of solvents, including water, acetone, and chloroform. Its chemical structure consists of a three-carbon chain with two hydroxyl groups attached to adjacent carbon atoms.

The production of propüleenglükoolil typically involves the hydration of propylene oxide. This process yields propüleenglükoolil as the primary product, with dipropylene glycol and tripropylene glycol as common byproducts. Propüleenglükoolil exists in two stereoisomeric forms, R and S, due to the presence of a chiral center. The commercially available product is usually a racemic mixture.

Propüleenglükoolil finds widespread use across various industries due to its properties as a humectant, solvent, and preservative. In the food industry, it is designated as E1520 and is used in flavorings, colorings, and as a carrier for other additives. In pharmaceuticals, it serves as a solvent for oral, injectable, and topical medications. Its low toxicity and ability to absorb moisture make it a common ingredient in cosmetics and personal care products, such as moisturizers, lotions, and toothpaste. It is also utilized in the manufacturing of antifreeze and de-icing fluids, as well as in e-cigarettes as a base for e-liquids.
