The molecular structure of isomeric alcohol polyoxyethylene ether E-1303 (CAS No.: 9043-30-5) utilizes branched isotridecanol as the hydrophobic group, which is fundamentally different from traditional linear alcohol ether surfactants. The branched structure allows the molecules to arrange more compactly and orderly at the oil-water interface, thereby effectively reducing oil-water interfacial tension, forming stable and fine emulsions. This property makes it a key component for efficient emulsification in industrial formulations.
With its unique branched hydrophobic structure, E-1303 possesses excellent wetting and penetrating properties. It can quickly spread and penetrate into the substrate surface and tiny gaps, significantly improving the processing efficiency of cleaning, scouring, degreasing, and other processes. Meanwhile, in a wide range of acidic, alkaline, and hard water environments, the product maintains excellent activity and compatibility, demonstrating outstanding chemical stability and not easily deactivated by changes in water quality or pH conditions.
In practical applications, E-1303 exhibits lower foaming tendency compared to linear alcohol ether products, facilitating cleaning and rapid rinsing, making it particularly suitable for industrial cleaning scenarios requiring low foam. Additionally, its broad compatibility allows it to be well compatible with anionic, cationic, and other nonionic surfactants, providing great flexibility for complex industrial formulations.
