Glycerol /ËÉ¡lÉªsÉrÉl/ (also called glycerine or glycerin; see spelling differences) is a simple polyol (sugar alcohol) compound. It is a colorless, odorless, viscous liquid that is widely used in pharmaceutical formulations. Glycerol has three hydroxyl groups that are responsible for its solubility in water and its hygroscopic nature. The glycerol backbone is central to all lipids known as triglycerides.
Glycerin is a compound that can be made from natural products such as vegetable oil, or can be synthesized from propylene alcohol. The result is an alcohol-based product that is an ingredient in many skin-care products. Glycerin, also called glycerol, can be used for both cosmetic purposes and as a treatment for medical conditions of the skin. Most people are very tolerant of glycerin, without experiencing irritation.
