Glycerine

Glycerol or glycerine or glycerin  is a colorless, odorless, viscous liquid that is sweet-tasting and non-toxic. Physically, glycerine is a water-soluble, clear, colorless and odorless, sweet-tasting and viscous liquid with a high boiling point. Chemically, glycerine is a trihydric alcohol capable of being reacted yet stable under most conditions. Because of these unusual properties, its good compatibility with numerous other substances and the ease of processing it, glycerine is used in many areas. Glycerine is a sugar alcohol and the simplest trihydric alcohol, a triol .  The glycerol backbone is found in many lipids which are known as glycerides. Glycerine is a by-product of saponified, hydrolyzed or transesterfied fats and oils . It is widely used as a sweetener in the food industry and as a humectant in pharmaceutical formulations. Glycerol has three hydroxyl groups that are responsible for its solubility in water and its hygroscopic nature
