Glycerin

Glycerol (glycerine) is a simple polyol compound. It is a colourless, odourless, viscous liquid that is widely used in pharmaceutical formulations. Glycerol has three hydrophilic hydroxyl groups that are responsible for its solubility in water and its hygroscopic nature. The glycerol backbone is central to all lipids known as triglyceride. Glycerol is sweet-tasting and of low toxicity.
