propilénglikol

Propylene glycol is a synthetic liquid substance that absorbs water. It is used to make products used in food, cosmetics, and pharmaceuticals. It is also used in e-cigarettes. Propylene glycol is generally recognized as safe by the U.S. Food and Drug Administration.

Propylene glycol is a viscous, colorless liquid that is nearly odorless but has a faint sweet taste. It is miscible with a broad range of solvents, including water, acetone, and chloroform. It is hygroscopic, meaning it attracts and holds water molecules. This property makes it useful in many applications where moisture retention is important.

In the food industry, propylene glycol is used as a humectant, solvent, and preservative. It can be found in baked goods, flavorings, and food colorings. In cosmetics and personal care products, it is used as a moisturizer, solvent, and viscosity-decreasing agent. It is a common ingredient in lotions, shampoos, and makeup.

In pharmaceuticals, propylene glycol is used as a solvent for oral, injectable, and topical medications. It can help dissolve active ingredients and improve their bioavailability. In e-cigarettes, it is a primary component of the liquid, often mixed with vegetable glycerin, to produce vapor when heated.

Propylene glycol is generally considered safe for human consumption and topical application. However, some individuals may experience allergic reactions or skin irritation. In very high doses, it can cause central nervous system depression. It is important to follow product labeling and usage instructions.
