Glycerol CAS#56-81-5
Glycerol is a colorless, viscous, hygroscopic, sweet-tasting trihydric alcohol. It is also called glycerin or glycerine, with the term glycerol being preferred as the pure chemical form and the term glycerin(e) being primarily used when the compound is used commercially in various grades.
Application Of Glycerol CAS#56-81-5
It is a raw material for the production of nitroglycerin, acetic acid glycerol, surfactants, flavors, alkyds and ester gums. It can be directly used in antifreeze, cosmetics, inks, etc.
It can be used as water-retaining agent (used for bread and cake); carrier solvent (used in flavor, pigment and water-soluble preservative; thickener (used for drink and wine formulation); plasticizer (candy, desert and meat product); sweetener, gas chromatographic fixative.
EEC provides it can be used for alcoholic beverages, candy, cakes, coating glazing, meat and cheese coating, alcoholic beverages, bakery products, gelatin, gelatin and other sweets.
