Propüleenglükooliga

Propüleenglükooliga, more commonly known as propylene glycol, is a synthetic liquid that absorbs water. It is widely used in a variety of commercial and industrial applications. Its chemical formula is C3H8O2. It is a viscous, colorless liquid that is nearly odorless but has a faintly sweet taste. Propylene glycol is miscible with a broad range of solvents, including water, acetone, and chloroform.

In the food industry, it is used as a food additive (E1520) to help retain moisture, improve texture, and prevent spoilage. It can be found in a variety of processed foods such as baked goods, ice cream, and beverages. In pharmaceuticals and cosmetics, it serves as a solvent and humectant, meaning it helps to retain moisture. It is an ingredient in many lotions, creams, toothpaste, and medications.

Propylene glycol also has industrial uses. It is a key component in the production of polyester resins and is used as a de-icing fluid for aircraft. In electronic cigarettes, it is one of the main ingredients in the e-liquid, acting as a carrier for nicotine and flavorings. While generally recognized as safe for consumption in regulated amounts, concerns have been raised about its potential effects when inhaled in high concentrations, leading to ongoing research and regulatory discussions.
