In the complex world of chemical manufacturing, sourcing reliable, high-quality raw materials is paramount. Propylene Glycol (PG), with its CAS number 57-55-6, stands out as a remarkably versatile compound, essential across a broad spectrum of industries. As a leading manufacturer and supplier in China, we understand the critical role PG plays in your product's success, from industrial resins to pharmaceuticals and cosmetics. This guide aims to illuminate why sourcing premium Propylene Glycol is a strategic decision for manufacturers worldwide.

Propylene Glycol, scientifically known as propane-1,2-diol, is a clear, colorless, and viscous liquid characterized by its low toxicity, near-odorlessness, and a faintly sweet taste. Its chemical formula, C3H8O2, belies its extensive utility. It's a diol, meaning it possesses two hydroxyl groups, which makes it highly miscible with a vast array of solvents, including water, acetone, and chloroform. This exceptional solvency is a key reason why it is sought after by various industries.

For manufacturers, understanding the grades available is crucial. We offer Propylene Glycol in both USP (United States Pharmacopeia) and Technical grades. The USP grade is vital for pharmaceutical and food applications where stringent purity standards are non-negotiable. The Technical grade, while offering excellent performance, is typically suited for broader industrial applications such as in the production of unsaturated polyester resins, antifreeze, and hydraulic fluids. Ensuring you select the correct grade is the first step in a successful procurement process. If you are looking to buy industrial grade propylene glycol for your manufacturing needs, or high-purity USP grade for sensitive applications, we are your trusted partner.

The applications of Propylene Glycol are incredibly diverse. In the pharmaceutical industry, it serves as a crucial excipient – a solvent or carrier for oral, injectable, and topical medications. Its ability to dissolve many poorly soluble drugs, coupled with its low toxicity, makes it indispensable. For cosmetic and personal care manufacturers, PG acts as a powerful humectant, drawing moisture to the skin, and as a solvent for active ingredients and fragrances. The cosmetic use of propylene glycol is extensive, found in everything from moisturizers and shampoos to makeup. Its designation as GRAS (Generally Recognized As Safe) by the FDA further solidifies its importance in food products, where it functions as a humectant, stabilizer, and solvent for flavors and colors (E1520). Procurement teams seeking propylene glycol price for cosmetic use or food applications will find our wholesale offerings highly competitive.

Furthermore, its role in industrial sectors cannot be overstated. As a component in engine coolants and antifreeze, its freezing point depression properties are invaluable. It's also used in hydraulic fluids, deicing fluids for aircraft, and as a solvent in paints and coatings. The demand for reliable cas 57-55-6 supplier in China is high, and we pride ourselves on meeting this demand with consistent quality and service.
