Propylene Glycol (CAS: 57-55-6) is a cornerstone organic chemical, celebrated for its versatility and wide-ranging industrial applications. With a typical purity of 99.8%, this clear, viscous liquid serves as an essential component across numerous sectors, from manufacturing to consumer goods. As a leading chemical intermediate and solvent supplier, understanding these applications is key for businesses looking to leverage its unique properties.

One of the primary roles of Propylene Glycol is as a chemical intermediate. It is a vital building block in the production of unsaturated polyester resins, which are used in fiberglass-reinforced plastics for boats, automobiles, and construction materials. Its ability to react with acids and form esters makes it indispensable in various synthesis processes within the chemical industry. Manufacturers seeking a reliable source for this intermediate can significantly benefit from sourcing from experienced Chinese chemical suppliers.

In the food and beverage industry, food-grade Propylene Glycol acts as a humectant, solvent, and preservative. It helps maintain moisture in foods, dissolve colors and flavors, and prevent spoilage. When purchasing for food applications, ensuring the product meets stringent food-grade certifications is crucial. Businesses looking to buy food-grade Propylene Glycol will find competitive pricing and assured quality from reputable manufacturers.

The cosmetic and personal care sector also heavily relies on Propylene Glycol for its moisturizing and solvent properties. It's commonly found in lotions, creams, shampoos, and deodorants, helping to retain moisture and improve product texture. Cosmetic formulators can source this ingredient from dependable suppliers to ensure the safety and efficacy of their products.

Furthermore, Propylene Glycol is a key ingredient in antifreeze and de-icing fluids due to its low freezing point. It's also utilized in hydraulic fluids, as a plasticizer for textiles, and in the formulation of certain pharmaceuticals as a solvent or excipient. The broad applicability underscores why a consistent and quality-assured supply of Propylene Glycol is essential for many global industries. For businesses needing to purchase this versatile chemical, partnering with a dedicated Chinese supplier offers the advantage of scale, expertise, and competitive pricing.
