Propylene Glycol, identified by its CAS number 57-55-6, is a fundamental organic chemical compound with widespread applications across diverse industries. Its unique chemical structure and properties as a diol make it an indispensable ingredient for formulators in cosmetics, pharmaceuticals, food, and various industrial sectors. For businesses seeking a reliable source for this crucial chemical, understanding its specifications and identifying competent China manufacturers and suppliers is key. This article provides insight into the importance of CAS 57-55-6 and how to source it effectively.

Understanding Propylene Glycol (CAS 57-55-6)

Propylene Glycol (C3H8O2) is a viscous, colorless, and transparent liquid that is nearly odorless but possesses a faintly sweet taste. Its molecular weight is approximately 76.09 g/mol. The CAS number 57-55-6 serves as a unique identifier for this specific chemical compound, essential for accurate identification in global trade, regulatory compliance, and scientific research. High-purity grades, such as USP (United States Pharmacopeia) or FCC (Food Chemicals Codex) grades, are critical for applications where safety and performance are paramount. When you buy Propylene Glycol, confirming its CAS number and grade is the first step to ensuring it meets your project's requirements.

Applications Driven by Purity and Performance

The versatility of Propylene Glycol stems from its excellent solvent, humectant, and antifreeze properties. In the cosmetic industry, it's a beloved humectant for skin and hair care products, a solvent for fragrances, and a component in toothpaste. The pharmaceutical sector utilizes it as a co-solvent for poorly soluble APIs, a stabilizer in liquid and semi-solid formulations, and a component in injectable drugs. The food industry employs it as a solvent for flavors and colors, an emulsifier, and a humectant to maintain product texture. For businesses in these sectors looking to purchase Propylene Glycol, sourcing from a reputable supplier that guarantees high purity is non-negotiable. This ensures the final product’s safety and efficacy.

Sourcing High-Purity Propylene Glycol from China

China has emerged as a significant global producer of chemical intermediates, offering competitive pricing and vast production capacities. When seeking a China manufacturer for Propylene Glycol (CAS 57-55-6), focus on those specializing in high-purity grades. Look for companies that provide detailed specifications, including assay percentages (e.g., 99.5% min), low residue on ignition, and controlled impurity levels. Furthermore, ensure they have a strong quality management system and can provide necessary documentation like Certificates of Analysis. When you inquire about the price, consider the overall value, including quality assurance, reliable delivery, and customer service. Establishing a relationship with a trusted chemical intermediate supplier in China can secure your supply chain for this vital ingredient.

In conclusion, Propylene Glycol (CAS 57-55-6) is a cornerstone ingredient in numerous industries. By diligently selecting a qualified manufacturer that prioritizes purity and reliability, businesses can effectively source this chemical intermediate to meet their formulation and production needs.
