Propane-1,2-triol

Propane-1,2-triol, more commonly known as glycerol or glycerin, is a simple polyol compound. It is a colorless, odorless, viscous liquid that is sweet-tasting and non-toxic. The molecule features three hydroxyl (-OH) groups, making it hygroscopic (readily absorbs moisture from the air) and miscible with water and many organic solvents. Glycerol is a crucial component of lipids (fats and oils), and it serves as an important intermediate in carbohydrate metabolism. Industrially, it is produced from the hydrolysis of fats or from propylene. Its versatility leads to its widespread application in numerous sectors, including food, pharmaceuticals, cosmetics, and manufacturing.
