Glycerol, also known as glycerin, is an organic compound with the chemical formula C3H8O3. It is a simple polyol compound, appearing as a colorless, odorless, non-toxic, viscous liquid with a sweet taste. Due to its three hydroxyl groups, glycerol is miscible with water and exhibits hygroscopic properties. Because of its antibacterial and antiviral characteristics, it is widely used in FDA-approved wound and burn treatments. It can also serve as a bacterial culture medium and an effective biomarker for assessing liver diseases. Additionally, glycerol is extensively used as a sweetener in the food industry and as a humectant in pharmaceutical formulations.
