What it is

Glycerin, also known as glycerol, is a simple polyol compound. It is a colorless, odorless, viscous liquid that is sweet-tasting and non-toxic. Glycerin can be derived from plant oils, animal fats, or petroleum.

Why it's used

International bodies like JECFA and EFSA have evaluated glycerin, and it is considered safe for consumption. Evidence does not suggest adverse health effects at typical dietary intake levels.
