Propylene glycol is prevalent in a wide array of products. In the pharmaceutical industry, it serves as a solvent for oral, injectable, and topical formulations. Its ability to maintain moisture makes it a common ingredient in cosmetic products like shampoos and lotions. In the food industry, it functions as a food additive (E1520), helping to preserve moisture and disperse flavors evenly. Additionally, it's used in antifreeze and de-icing solutions due to its low freezing point.
