propane11diol

Propane-1,2-diol, also known as propylene glycol, is a synthetic organic compound with the chemical formula C3H8O2. It is a viscous, colorless, and nearly odorless liquid that is hygroscopic and miscible with a wide range of solvents, including water, acetone, and chloroform. Propane-1,2-diol is produced industrially from propylene oxide, which is derived from petroleum.

Its versatility makes it a common ingredient in many consumer products. In the food industry, it is used as a solvent for flavors and colors, a humectant to retain moisture, and an emulsifier. It is also found in pharmaceuticals as a solvent for oral, injectable, and topical medications. In cosmetics and personal care products, propane-1,2-diol acts as a moisturizer, a solvent, and a viscosity-decreasing agent in products like lotions, shampoos, and deodorants.

In industrial applications, propane-1,2-diol serves as a coolant and antifreeze fluid due to its low freezing point. It is also used in the manufacturing of unsaturated polyester resins, which are employed in fiberglass-reinforced plastics. While generally recognized as safe (GRAS) by regulatory agencies for food use, some individuals may experience allergic reactions or skin irritation upon contact. In large doses, it can have adverse health effects, but typical consumer product concentrations are considered safe.
