Understanding Polyoxyethylene Stearyl Ether (CAS 9005-00-9): A Chemist's Perspective
For research scientists and chemical engineers, a deep understanding of a compound's chemistry is fundamental to its successful application. Polyoxyethylene Stearyl Ether, identified by CAS number 9005-00-9, is a non-ionic surfactant with a fascinating molecular architecture and a wide array of functional properties. This article provides a scientific perspective on this compound, detailing its chemical characteristics, synthesis routes, and the critical role it plays in formulation science. We also offer guidance on sourcing this valuable material from reputable manufacturers and suppliers.
From a chemical standpoint, Polyoxyethylene Stearyl Ether is an ether formed by the ethoxylation of stearyl alcohol. The general formula, C18H37(OCH2CH2)nOH, illustrates a stearyl (C18) hydrophobic tail attached to a variable number of ethylene oxide units (oxyethylene chain), conferring hydrophilicity. The length of this polyoxyethylene chain (represented by 'n') dictates its solubility and surfactant characteristics. Its molecular weight can vary significantly based on the degree of ethoxylation, with common grades having molecular weights around 1151.56. The density (approximately 0.867-0.964 g/cm³) and boiling point (around 100°C, though it decomposes at higher temperatures) are important handling considerations.
The synthesis of Polyoxyethylene Stearyl Ether typically involves the reaction of stearyl alcohol with ethylene oxide under controlled catalytic conditions. This process, known as ethoxylation, allows for the precise tailoring of the surfactant's properties by adjusting the ethylene oxide to alcohol ratio. For chemists and formulators aiming to buy high-purity Polyoxyethylene Stearyl Ether, understanding these manufacturing nuances can be crucial for batch-to-batch consistency.
In laboratory and industrial settings, Polyoxyethylene Stearyl Ether functions effectively as an emulsifier, stabilizer, and solubilizer. Its non-ionic nature makes it compatible with a broad range of other ingredients, including ionic compounds, which is a significant advantage in complex formulations. For example, in creating stable oil-in-water emulsions, its amphipathic structure allows it to bridge the oil and water phases effectively.
