propanetriol

Propanetriol, also known as glycerol or glycerin, is a simple polyol compound. Its chemical formula is C3H8O3. It is a colorless, odorless, viscous liquid that is sweet-tasting and non-toxic. Propanetriol is soluble in water and alcohol but not in oils. It is a trihydroxy alcohol, meaning it contains three hydroxyl (OH) groups attached to a three-carbon chain. This structure is responsible for its ability to attract and hold water, a property known as hygroscopicity.

Propanetriol is a common component of triglycerides, which are fats and oils. It is produced commercially through the saponification of fats and oils, or as a byproduct of biodiesel production. Its versatility leads to a wide range of applications. In the food industry, it is used as a humectant, solvent, sweetener, and thickener. In pharmaceuticals and personal care products, it acts as a moisturizer, emollient, and solvent in lotions, soaps, toothpaste, and medicines. Propanetriol is also used in the production of explosives, such as nitroglycerin, and in the manufacturing of plastics and resins. Its low toxicity and moisturizing properties make it a valuable ingredient in many consumer and industrial products.
