Polyethylene Glycol Monocetyl Ether (CAS 9004-95-9) is a fascinating chemical compound that plays a critical role in numerous product formulations. As a non-ionic surfactant, it bridges the gap between oil and water, enabling a wide array of applications in the pharmaceutical, cosmetic, and industrial sectors. Understanding its inherent properties is key to leveraging its full potential, and for businesses looking to buy this compound, a deep dive into its science is essential.

Chemically, Polyethylene Glycol Monocetyl Ether is an ethoxylated fatty alcohol, specifically derived from cetyl alcohol. Its structure, represented by the general formula HO(C2H4O)nC16H33, indicates the presence of a long hydrocarbon chain (hexadecyl, C16H33) which provides lipophilicity, and a chain of repeating ethylene oxide units (C2H4O)n, which imparts hydrophilicity. The degree of ethoxylation (represented by 'n') can vary, leading to different grades of the product, each with slightly altered properties, such as solubility and HLB (Hydrophilic-Lipophilic Balance) values.

Physically, Polyethylene Glycol Monocetyl Ether typically appears as a white, waxy solid. It exhibits a melting point range generally between 41-49 °C, with a boiling point around 35.4-39.6 °C. Its density is approximately 0.978 g/mL at 25 °C, and it has a low vapor pressure. Importantly, it is soluble in many organic solvents and possesses good solubility in water, which is a testament to its amphiphilic nature. Stability is another key characteristic; it is generally stable but should be stored away from strong oxidizing agents.

The applications of Polyethylene Glycol Monocetyl Ether are as diverse as its properties. In the cosmetics and personal care industry, it is widely used as an emulsifier and emollient in skin creams and lotions, providing a smooth, luxurious feel. It also acts as a solubilizer for fragrances and active ingredients in cosmetic formulations. For cosmetic formulators, securing a reliable supplier for this ingredient is vital for product consistency.

In the pharmaceutical field, its role as a solubilizer is particularly noteworthy. Many active pharmaceutical ingredients (APIs) exhibit poor aqueous solubility, which can hinder their absorption and therapeutic effectiveness. Polyethylene Glycol Monocetyl Ether can significantly enhance the solubility of such compounds, facilitating their delivery through various routes. It is also used as a component in ointment bases and as a wetting agent for solid dosage forms. Pharmaceutical companies often source this material from specialized manufacturers to ensure the highest purity and compliance with regulatory standards.

Moreover, in industrial settings, it serves as a wetting agent, dispersant, and lubricant. Its effectiveness in reducing interfacial tension makes it suitable for applications such as textile processing and as a component in industrial cleaning solutions. The ability to purchase this chemical in bulk from a trusted source is crucial for large-scale industrial operations.

When seeking to acquire Polyethylene Glycol Monocetyl Ether, it is imperative to partner with a reputable manufacturer in China. These suppliers can offer competitive prices, consistent quality, and the technical documentation required for compliance. Thoroughly evaluating potential suppliers based on their production capabilities, quality control processes, and customer service is a prudent step for any B2B purchaser.

In essence, Polyethylene Glycol Monocetyl Ether (CAS 9004-95-9) is more than just a chemical; it's an enabler of advanced formulations. Its scientific underpinnings explain its broad utility, making it a cornerstone ingredient for innovation across multiple industries. By understanding its science and strategically sourcing from reliable partners, businesses can harness its full potential.
