Glycerol, also known commercially as glycerin or glycerine, is a colorless, viscous, hygroscopic trihydric alcohol. Its moisture-retaining character and liquid consistency support cosmetic, ink and antifreeze formulations. Reactive alcohol functionality also makes it a feedstock for glycerol esters, surfactants, alkyd resins, ester gums and flavor-related chemicals, linking direct formulation use with broader chemical manufacture.
