Glycerin

CAS NO. 56-81-5 

Technical Grade 

Description: Glycerin (glycerol) is a simple chemical compound consisting of three carbon atoms, eight hydrogen atoms, and three hydroxyl (-OH) groups. Each carbon in the chain is linked to a hydroxyl group (-OH). The presence of these groups makes glycerin an alcohol, more specifically, a triol because it contains three hydroxyl groups. The hydroxyl groups make glycerin highly polar. These groups can form hydrogen bonds with water and other polar molecules, explaining its good solubility in water. It is insoluble in oils and many hydrophobic solvents. Glycerin is a clear, colorless, odorless viscous liquid. It has a sweet taste. The boiling point is around 290°C. Density is approximately 1.26 g/mL at 25°C. Glycerin is hygroscopic (absorbs water from the air); Generally stable, but can react with strong oxidizing agents. 99.5% glycerin indicates high purity, and as such, it is often used in pharmaceutical formulations, cosmetics as a humectant, and in the food industry.
