Glycerol is a colorless, sweet-tasting, clear and viscous liquid. Odorless. It has a warm sweet taste. Commonly known as glycerin, it can absorb moisture from the air, as well as hydrogen sulfide, hydrogen cyanide .Relative density: 1.26362. Melting point: 17.8ºC. Boiling point: 290.0ºC(decomposition). Refractive index: 1.4746. Glycerol is the backbone component of triglyceride molecules. When the human body takes in edible fat, the triglycerides within it are metabolized and decomposed in the body to form glycerol, which is then stored in fat cells. Therefore, the final products of triglyceride metabolism are glycerol and fatty acids. It can be used as a solvent, lubricant, medicine and sweetener.
