Glycerol - Wikipedia

Glycerol (/ ˈ ɡ l ɪ s ə r ɒ l /; also called glycerine or glycerin) is a simple polyol compound. It is a colorless, odorless, viscous liquid that is sweet-tasting and non-toxic. The glycerol backbone is found in those lipids known as glycerides.Due to having antimicrobial and antiviral properties it is widely used in FDA approved wound and burn treatments.
