About Our Propylene Glycol: Your Versatile Functional Ingredient Solution

Propylene Glycol (CAS No.: 57-55-6), also known as 1,2-propanediol, is a colorless, odorless, and viscous liquid with excellent solubility, humectant properties, and low toxicity. It is a versatile functional ingredient widely used in global industries, serving as a humectant, solvent, plasticizer, and antifreeze agent. It integrates seamlessly into various formulations without altering the core properties of the end products, making it an indispensable component in multiple fields.
Our propylene glycol is produced using advanced catalytic hydrogenation technology and strict quality control processes, ensuring high purity and consistent performance. It is available in food grade, pharmaceutical grade, and industrial grade, suitable for a wide range of applications, including:
- Food and beverages (humectant in baked goods, sweeteners, food preservatives, flavor carriers)
- Pharmaceuticals (solvent in oral medications, topical creams, injectables; excipient for drug formulations)
- Cosmetics and personal care (humectant in lotions, creams, shampoos, deodorants; emollient and solvent)
- Industrial applications (antifreeze in cooling systems, plasticizer in resins, solvent in coatings and inks)
Key advantages of our propylene glycol that meet global procurement requirements:
- Compliance with international standards (USP/EP/BP/FCC) for global market access
- High purity (≥99.8%) to ensure product safety and stable performance
- Low impurity content (free of heavy metals, aldehydes, and other harmful substances)
- Multiple grades available (food/pharmaceutical/industrial) to meet diverse application needs
- Factory direct supply with competitive pricing and flexible MOQ
- Reliable supply chain and on-time delivery for global shipments
