Refined glycerin is a water-soluble, colorless, odorless, viscous liquid with a high boiling point. Refined glycerin can be used in many applications since it is nontoxic to human health and the environment.

It is commonly used in personal care and cosmetics due to its ability to retain moisture. Being sweet-tasting, refined glycerine is widely used as sweetener in food. It can also be found in pharmaceutical products due to its non-toxic nature.
