propylen13diol

Propylene glycol, also known as propane-1,2-diol, is a synthetic organic compound with the formula C3H8O2. It is a viscous, colorless liquid that is nearly odorless but possesses a faint, sweet taste. Propylene glycol is miscible with a broad range of solvents, including water, acetone, and chloroform. Its properties make it a versatile ingredient in numerous industrial and commercial applications.

Industrially, propylene glycol is produced through the hydration of propylene oxide. It is a common component in the production of polyester resins, which are used in a wide variety of products such as textiles, food containers, and automotive parts. Additionally, its humectant properties, meaning it can retain moisture, make it valuable in cosmetics, personal care products, and pharmaceuticals. It acts as a solvent, emulsifier, and preservative in these formulations.

In the food industry, propylene glycol is approved as a food additive (E number E1520) and is used as a solvent for flavors and colors, and as a humectant to prevent food from drying out. It is also a key ingredient in e-cigarette liquids, acting as a base for nicotine and flavorings. Its low toxicity profile contributes to its widespread use across these diverse sectors.
