Applications of Propylene Glycol (USP)

• Antifreeze and Coolants: Propylene glycol is commonly used as a non-toxic antifreeze agent in automotive and industrial cooling systems. It prevents freezing and provides corrosion protection to metallic components.
• Heat Transfer Fluids: Due to its low viscosity, high boiling point, and thermal stability, propylene glycol is utilized as a heat transfer fluid in heating and cooling systems, including HVAC (heating, ventilation, and air conditioning) systems and solar thermal systems.
• Humectants and Solvents: Propylene glycol serves as a humectant and solvent in various industrial applications, including cosmetics, personal care products, pharmaceuticals, food processing, and tobacco products. It helps retain moisture, dissolve active ingredients, and improve product consistency.
• Hydraulic Fluids: In hydraulic systems, propylene glycol-based fluids are used as hydraulic fluids due to their lubricating properties, thermal stability, and non-toxic nature. They provide reliable performance in a wide range of temperatures and operating conditions.
• Food and Beverage: It is approved by regulatory agencies such as the U.S. Food and Drug Administration (FDA) for use as a food additive and is commonly found in food and beverage products. Propylene glycol (USP) is used as a humectant, solvent, stabilizer, and preservative in a wide range of food products, including baked goods, dairy products, beverages, and pharmaceutical preparations.
• Veterinary Medicine: Similar to its use in human pharmaceuticals, propylene glycol (USP) is employed in veterinary medicine for the formulation of oral, topical, and injectable medications for animals. It provides similar functions as in human pharmaceuticals, such as solubilization, preservation, and stabilization of drug formulations.
• Laboratory and Industrial Applications: In laboratory and industrial settings, propylene glycol (USP) finds applications as a solvent, reagent, and heat transfer fluid. It is used in chromatography, chemical synthesis, and as a non-toxic alternative to ethylene glycol in heat transfer and cooling systems.
