Propylene glycol is a colorless, odorless, and slightly sweet-tasting liquid commonly used in a wide range of industries, including food, pharmaceuticals, cosmetics, and personal care products. It is a type of alcohol that is derived from petroleum or natural gas and is used as a solvent, humectant, and preservative. In the food industry, propylene glycol is used as a food additive to help preserve moisture and maintain consistency in products such as baked goods, frostings, and salad dressings. In pharmaceuticals and personal care products, it is used as a solvent for active ingredients and as a humectant to prevent moisture loss.
