At NINGBO INNO PHARMCHEM CO.,LTD., we pride ourselves on offering a deep understanding of the chemicals we supply. C9-11 Alcohol Ethoxylates (CAS: 68439-46-3) are a fascinating group of nonionic surfactants whose utility stems directly from their unique chemical structure and properties.

At its core, a C9-11 Alcohol Ethoxylate is formed by reacting a mixture of C9 to C11 fatty alcohols with ethylene oxide (EO). The fatty alcohol component provides a hydrophobic (water-repelling) tail, typically a chain of 9 to 11 carbon atoms. The addition of ethylene oxide units creates a hydrophilic (water-attracting) head. The overall molecule thus possesses both hydrophobic and hydrophilic characteristics, making it an amphiphilic surfactant capable of interacting with both oil and water.

The degree of ethoxylation – the number of EO units attached – is a critical factor determining the ethoxylate's properties. For C9-11 Alcohol Ethoxylates, varying the number of EO units influences their solubility in water, their foaming characteristics, and their ability to emulsify or wet surfaces. For instance, as the number of EO units increases, the compound becomes more water-soluble and its detergency and solubilization power generally increase, while its degreasing ability may decrease. This allows formulators to select the precise ethoxylated C9-11 alcohols wetting agent or emulsifier needed for a specific application.

Understanding these chemical nuances is key to leveraging the full potential of C9-11 Alcohol Ethoxylates. Their amphiphilic nature allows them to gather at interfaces (like oil-water boundaries) and reduce interfacial tension, thereby enabling effective emulsification and dispersion. This property is fundamental to their role in products ranging from detergents, where they help lift and suspend dirt and oils, to personal care items, where they aid in the blending of oil-based and water-based ingredients.
