Propyleeniglykoliini

Propyleeniglykoliini, also known as 1,2-propanediol, is a synthetic organic compound. It is a viscous, colorless, and nearly odorless liquid that is hygroscopic, meaning it readily absorbs moisture from the air. Propyleeniglykoliini is miscible with water, acetone, and chloroform. It is produced industrially through the hydration of propylene oxide.

This compound has a wide range of applications due to its properties. It is commonly used as a humectant in cosmetics and personal care products, helping to retain moisture. In the food industry, it serves as a solvent for flavors and colors and as a preservative, though its use is regulated. Propyleeniglykoliini is also a key component in the production of unsaturated polyester resins, which are used in fiberglass-reinforced plastics. Additionally, it is utilized as a de-icing fluid for aircraft and as a component in antifreeze. Its low toxicity, when used as intended, contributes to its widespread use.
