What Is Vegetable Glycerin?
Vegetable glycerin, also known as vegetable glycerol, is a carbohydrate product derived from vegetable oils, such as coconut or palm. Uses of vegetable glycerin include cosmetic products and food. It is also used as a component in medical products such as tinctures, as a substitute for alcohol.
The basic chemical structure of vegetable glycerin is made up of three hydrogen atoms, three carbon atoms and three hydroxyl groups, which form hydrogen bonds with water. Pure glycerin is distilled after a process of keeping vegetable oils under pressure at temperatures exceeding 400 degrees F. The final product has the consistency of a syrup and it has no color and odor. The composition of vegetable glycerin is resistant to freezing.
