Glycerin, also known as Glycerol, is an organic compound with the chemical formula C₃H₈O₃. It is a clear, odorless, viscous liquid with a sweet taste. Due to its hygroscopic properties, glycerin is widely used in various industries. It can be derived naturally from fats and oils or produced industrially as a by-product of biodiesel production.

• Excellent humectant and emollient

• Widely used in pharmaceuticals and cosmetics

• Functions as a sweetener and stabilizer in food industry

• Used as a solvent in chemical and paint industries

• Applied in resins, plastics, and explosives (e.g., nitroglycerin)

Industrial Applications

• Pharmaceuticals (syrups, capsules, ointments)

• Food industry (confectionery, beverages, dairy products)

• Cosmetics and personal care (creams, shampoos, soaps)

• Chemicals and plastics (resins, paints, polymers)

One of the most remarkable historical applications of glycerin was in the 19th century when Alfred Nobel used it to produce nitroglycerin. This innovation eventually led to the invention of dynamite, which revolutionized the construction and mining industries by enabling safer and more controlled blasting.

Scientific Achievement

According to a 2024 article published in the Journal of Cleaner Production, glycerin is increasingly being utilized as a renewable raw material in the production of biodegradable plastics. This development highlights glycerin’s potential as a sustainable alternative to petroleum-based resources, especially in the packaging industry. Source Article
