Propylene glycol, also known as 1,2-propanediol, is a chemical compound with the chemical formula C₃H₈O₂. It is a colorless, nearly odorless, clear, viscous liquid. Structurally, it is a diol, which means it has two hydroxyl (-OH) groups attached to different carbon atoms of the propane molecule.
2 Applications
Food and Beverage Industry: Propylene glycol is used as a humectant to help retain moisture in food. It is found in products such as baked goods, processed meats, and some dairy products. It is also used as a solvent for food coloring and flavoring. In the beverage industry, it can be used to enhance the solubility of certain additives and prevent ice formation in certain ready-to-drink products.
Cosmetics and Personal Care: In cosmetics, it is used as a humectant and solvent. It helps keep the skin moisturized and is used in products such as lotions, creams, and makeup. Propylene glycol’s low toxicity and good skin compatibility make it a popular ingredient in personal care products.
Pharmaceutical Industry: Propylene glycol is used as a solvent and carrier for pharmaceuticals. It helps dissolve active pharmaceutical ingredients and improve their bioavailability. It is also used in some topical medications and cough syrups due to its ability to effectively dissolve and disperse active ingredients.
Antifreeze and Coolant Applications: It is a key ingredient in antifreeze and coolant mixtures. Propylene glycol-based antifreeze is less toxic than ethylene glycol-based antifreeze and is often used in applications where there is a higher risk of human or animal exposure, such as certain automotive cooling systems and heating, ventilation, and air conditioning (HVAC) systems.
