It functions primarily as a humectant, solvent, and preservative, helping to retain moisture, dissolve ingredients, and maintain product stability. PG is generally recognized as safe for consumption and topical use, and it is commonly found in items such as food flavorings, e-liquids, personal care products, and medications. Its chemical formula is C₃H₈O₂, and it is valued for its low toxicity, high miscibility with water, and ability to improve texture and shelf life in various formulations.
