Products Description of GlycerolCAS#56-81-5
Glycerol (chemical formula: CH₂OHCHOHCH₂OH), also referred to as glycerin or glycyl alcohol, is a clear, colorless, viscous liquid with a sweet flavor.
As the simplest trihydroxy alcohol, it is a valuable chemical intermediate. It is soluble in water and alcohol, but only partially miscible with ether and ethyl acetate.
Glycerol finds applications in the perfume and pharmaceutical industries, serves as an antifreeze, and is also used in the production of soaps and explosives.
