Trideceth-9
What is Trideceth-9?
Trideceth-9 is a synthetic non-ionic surfactant, chemically a polyoxyethylene (9) tridecyl ether, formed by ethoxylating tridecyl alcohol with nine units of ethylene oxide. This process creates a hydrophilic head and hydrophobic tail, ideal for amphiphilic behavior in formulations. It appears in rinse-off cleansers like shampoos and body washes, and leave-on products such as creams and lotions. In cleansing products, it reduces surface tension to lift away oils, dirt, and residues effectively. As an emulsifying agent, it creates a protective layer at oil-water boundaries, promoting blend stability, preventing separation, and ensuring even texture and spreadability for comfortable application across formulations.
