Propylene glycol india (PG) is a clear, colorless liquid with the consistency of syrup. It is practically odorless and tasteless. It is hygroscopic (attracts water), has low toxicity and outstanding stability, as well as high flash and boiling points, low vapor pressure and broad solvency. In addition, propylene glycol is an excellent solvent for many organic compounds and is completely water-soluble. These properties make PG ideal for a wide array of applications, such as:
• Antifreezes, Coolants and Aircraft Deicing Fluids
• Chemical Intermediates
• Cosmetics and Personal Care Products
• Flavors and Fragrances
• Food
• Heat Transfer Fluids
• Hydraulic Fluids
• Pharmaceuticals
• Plasticizers
• Solvents
• Thermoset Plastic Formulations
