Glycerin (or glycerine, glycerol) is a triol or polyol compound. In its pure form, glycerin is a colorless odorless, sweet tasting, viscous liquid. As an alcohol with three hydroxyl groups it is hydroscopic and soluble in water.

Typical Characteristics: 

• Disrupts ice formation and good for low temperatures
• Three hydroxyl groups provide hygroscopicity (attracts water)
• A sweet, simple polyol which is viscous and non-toxic
• 100% naturally derived
• Functions as a humectant, lubricant, solvent, viscosity modifier, emulsifier, and excipient
