Glycerol is widely used in the food industry as a sweetener, solvent, and humectant, helping to maintain moisture in products like baked goods and candies. In pharmaceuticals, it serves as a lubricant in capsules and tablets, and as a component in cough syrups and expectorants. The cosmetics industry utilizes glycerol for its moisturizing properties, making it a common ingredient in lotions, creams, and soaps. Additionally, glycerol is employed in the production of antifreeze, plastics, and resins, and as a substrate in fermentation processes for biofuels. Its versatility also extends to medical applications, where it is used in suppositories and as a hyperosmotic agent to reduce intracranial pressure.
