Understanding the fundamental chemistry of surfactants is crucial for formulators across various industries. Non-ionic surfactants, in particular, offer a unique set of properties that make them highly versatile. Fatty Alcohol Ethoxylates, commonly identified by CAS number 68439-50-9, are prime examples, and as a leading chemical manufacturer and supplier, we are dedicated to sharing insights into their structure and function.

Fatty Alcohol Ethoxylates are synthesized through a process known as ethoxylation, where fatty alcohols (typically a blend of C12-C14 chains) are reacted with ethylene oxide. This reaction attaches chains of repeating ethylene oxide units (-OCH2CH2-) to the fatty alcohol molecule. The fatty alcohol portion provides the hydrophobic (water-repelling) character, while the ethylene oxide chains contribute the hydrophilic (water-attracting) character. This dual nature allows them to orient themselves at interfaces, such as oil-water or air-water boundaries, thereby reducing surface tension.

The degree of ethoxylation—the number of ethylene oxide units added—significantly influences the surfactant's properties, such as its solubility, foaming ability, and emulsification power. For instance, surfactants with shorter ethylene oxide chains tend to be more oil-soluble and are often used as intermediates, while those with longer chains are more water-soluble and function effectively as detergents and emulsifiers. This controllability makes them incredibly adaptable for specific applications.

As a chemical supplier based in China, we ensure that our Fatty Alcohol Ethoxylates are produced with precise control over the ethoxylation process, guaranteeing consistent quality and performance. Businesses looking to buy these surfactants can rely on our expertise to source ingredients that will effectively meet their formulation needs, whether for cleaning, personal care, or industrial applications.
