Ingredient
Glycerine
What is Glycerine?
Glycerine, also known as glycerol, is a simple polyol compound. It is a colorless, odorless, and sweet-tasting liquid that is derived from animal fats or, more commonly, from the production of plant oils.
Glycerine is used in food and personal care products as a humectant, meaning it helps retain moisture. In food, it can function as a sweetener or thickener, and in cosmetics, it is often utilized for its moisturizing properties. Health evidence shows it is generally safe for consumption at typical usage levels.
On labels, glycerine indicates that the product may have additional moisturizing properties or sweetness without added sugar. It is often found in pharmaceuticals, foods, and personal care items.
Commonly found in: Protein bars, Lotions, Toothpaste, Processed foods, Pharmaceuticals, Soaps

Glycerine is recognized as Generally Recognized As Safe (GRAS) for use in foods by the FDA.
Research indicates glycerine is safe, but excessive intake can lead to gastrointestinal issues.
While often plant-derived, glycerine can also be sourced from animal fats, so its vegan status can vary.
