Polysorbate 20 (CAS 9005-64-5): Properties, Uses, and Key Suppliers
Polysorbate 20, identified by its CAS number 9005-64-5, is a workhorse ingredient in numerous industrial and consumer products. This nonionic surfactant is highly valued for its emulsifying, solubilizing, and detergent properties, making it indispensable in sectors ranging from pharmaceuticals to cosmetics and food production. Understanding its chemical characteristics and diverse applications sheds light on its widespread importance.
Chemically, Polysorbate 20 is a polyoxyethylene ether of sorbitan monolaurate. It is derived from sorbitol, a sugar alcohol, and lauric acid, a fatty acid. The '20' in its name refers to the average number of ethylene oxide repeating units in the molecule, which imparts its hydrophilic nature. This balance between its hydrophobic fatty acid tail and hydrophilic polyoxyethylene chain is what allows it to effectively reduce interfacial tension between oil and water phases.
The physical properties of Polysorbate 20 are also noteworthy. It typically appears as a light yellow, viscous liquid. Its stability and relative nontoxicity further enhance its appeal across various applications. For formulators and manufacturers, having a reliable source for this compound is crucial. Companies looking to buy Polysorbate 20 will often search for specifications such as its molecular formula (C26H50O10) and molecular weight (522.6692 g/mol).
The applications of Polysorbate 20 are extensive. In the pharmaceutical industry, it acts as an emulsifier and solubilizer, essential for creating stable drug formulations, including ointments, creams, and oral solutions. Its ability to improve the solubility of lipophilic drugs enhances their bioavailability. For those in the pharmaceutical sector, sourcing 'high purity Polysorbate 20' from a reputable 'Polysorbate 20 supplier' is a priority.
In the cosmetic and personal care realm, Polysorbate 20 is a ubiquitous ingredient. It functions as an emulsifier in lotions and creams, a solubilizer for fragrances and essential oils in perfumes and body sprays, and a detergent in shampoos and facial cleansers. The demand for 'cosmetic grade Polysorbate 20' drives manufacturers to ensure consistent quality and supply.
The food industry also utilizes Polysorbate 20 as an emulsifier and stabilizer, contributing to the texture and shelf-life of products like baked goods, confectionery, and dairy items. Its safety and effectiveness in these applications have led to its widespread acceptance.
For businesses seeking to purchase Polysorbate 20, identifying key suppliers is paramount. Manufacturers in China are prominent players in the global market, offering competitive pricing and the ability to supply in bulk. When searching for a 'Polysorbate 20 manufacturer,' it is advisable to look for those who provide comprehensive product data, offer free samples for quality assessment, and can meet the specific grade requirements of your industry. Engaging with a trusted supplier ensures a consistent and high-quality supply of this vital chemical intermediate.
