Trideceth-8
What is Trideceth-8?
Trideceth-8 is a synthetic non-ionic surfactant chemically known as a polyethylene glycol ether of tridecyl alcohol, featuring eight ethylene oxide units. Derived from tridecyl alcohol, a branched fatty alcohol often sourced from petrochemical processes, it undergoes ethoxylation to enhance its solubility and functionality in water-based systems. Primarily used in rinse-off products like shampoos, body washes, and facial cleansers, as well as leave-on emulsions such as lotions and creams, Trideceth-8 lowers interfacial tension to disperse oils and dirt effectively. Its surfactant properties enable lather formation and soil removal, while its emulsifying action creates a stable film between immiscible phases, preventing separation and delivering smooth, uniform textures. This makes it a key component in maintaining product integrity across various personal care formulations.
