Propylene glycol is a clear, colorless, and nearly odorless liquid with a slightly sweet taste. It is a viscous, water-soluble, and hygroscopic compound commonly used as a solvent, humectant, and lubricant in a variety of industries. Propylene glycol can also be used as a food additive and in pharmaceutical and personal care products due to its low toxicity and stability. It has a boiling point of 188.2°C and a melting point of -59°C.
Propylene glycol (PG) has a wide range of applications in the energy sector. It is commonly used as a heat transfer fluid due to its low freezing point and high boiling point. It is also used as a component in drilling fluids, which are used to cool and lubricate drilling bits during oil and gas exploration. Additionally, propylene glycol is used as a solvent in oil and gas extraction processes, as well as in the production of biodiesel. Its low toxicity and biodegradability make it a preferable alternative to other chemicals in many energy applications.
Propylene glycol is used in the pharmaceutical industry as a solvent and excipient, meaning it can dissolve and stabilize other active ingredients in drugs. It is commonly found in oral, topical, and parenteral (injectable) formulations. Additionally, it is used as a humectant in various pharmaceutical products to prevent them from drying out. Propylene glycol is also used in the production of vaccines to stabilize and protect the active ingredients. Its low toxicity and ability to mix with both water and oil make it a versatile ingredient in various pharmaceutical applications.
