Refined Glycerine
Refined Glycerine also called glycerine or glycerin is a simple polyol compound. It is a colorless, odorless, viscous liquid that is sweet-tasting and non-toxic. The glycerol backbone is found in all lipids known as triglycerides. It is widely used in the food industry as a sweetener and humectant and in pharmaceutical formulations. Glycerol has three hydroxyl groups that are responsible for its solubility in water and its hygroscopic nature.
Refined Glycerine. It is a byproduct obtained in the production of fatty acids and castor oil derivatives such as 12 hydroxy stearic acid and recinolic acid. We make available Refined Glycerine in different grades such as Industrial white (IW), Chemically Pure (CP) and Pharmaceutical grades such as IP, BP and USP. We use HDPE barrels for packing Refined Glycerine.
