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
