In the complex world of chemical sourcing, identifying reliable suppliers for high-quality ingredients is paramount. For professionals in the food, pharmaceutical, and cosmetic industries, USP Grade Propylene Glycol stands out as a remarkably versatile compound. As a premier supplier based in China, we understand the critical role this ingredient plays in your formulations. This article aims to provide chemists and procurement specialists with a comprehensive understanding of Propylene Glycol (PG) and how to effectively buy it.

Understanding Propylene Glycol’s Chemical Profile
Propylene Glycol, also known by its CAS number 57-55-6, is a synthetic organic compound with the chemical formula C3H8O2. It is characterized as a diol, meaning it possesses two hydroxyl (-OH) groups. Physically, it presents as a clear, viscous liquid that is nearly colorless and possesses a very mild odor, making it almost tasteless. This chemical inertness, combined with its excellent hygroscopic and solvent properties, underpins its widespread utility. Its low vapor pressure and low toxicity also contribute significantly to its appeal as a safer alternative to other glycols, notably ethylene glycol.

Key Functions and Applications for Buyers
The versatility of propylene glycol makes it indispensable across numerous sectors. As a humectant, it attracts and retains moisture, crucial for maintaining the desired texture and preventing drying out in food products like baked goods, cosmetics, and pharmaceuticals. Its solvent capabilities allow it to dissolve flavors, colors, and active ingredients, ensuring uniform dispersion and efficacy. Furthermore, its emulsifying properties help bind oil and water components, leading to stable and consistent product formulations. When you purchase USP Grade Propylene Glycol, you are investing in a raw material that can function as:

  • A Humectant: Essential for moisture retention in skincare, food products, and tobacco.
  • A Solvent: Ideal for carrying flavors, fragrances, and active pharmaceutical ingredients.
  • An Emulsifier: Blending immiscible liquids for consistent textures in creams and food products.
  • A Preservative: Helping to prevent spoilage and extend shelf life.
  • A Base: For antifreeze solutions, de-icing fluids, and even theatrical fog.

Safety and Regulatory Compliance: A Manufacturer’s Priority
The Food and Drug Administration (FDA) has classified propylene glycol as Generally Recognized As Safe (GRAS) for use in food. This designation underscores its safety profile when used within established limits. For industries requiring the highest standards, USP Grade Propylene Glycol is imperative. This certification signifies that the product meets the rigorous purity and quality standards set forth by the United States Pharmacopeia, ensuring it is fit for use in food, drug, and cosmetic applications. As a responsible supplier, we ensure our propylene glycol adheres to these critical regulatory requirements, providing peace of mind to our clients when they buy our products.

Sourcing High-Quality Propylene Glycol: What to Look For
When seeking to buy propylene glycol, particularly for sensitive applications, several factors are key: purity (USP Grade), consistency, and reliable supply. Working with a reputable manufacturer or supplier that can provide detailed specifications and Certificates of Analysis (CoA) is crucial. Understanding the different grades available and ensuring the one you select meets your specific application's needs is vital for product success. If you are looking for a trusted manufacturer of propylene glycol in China, look no further.
