Trideceth-15
What is Trideceth-15?
Trideceth-15 is a synthetic polyethylene glycol ether derived from tridecyl alcohol, where the alcohol chain is ethoxylated with approximately 15 units of ethylene oxide. This chemical structure imparts hydrophilic and lipophilic properties, classifying it as a nonionic surfactant. In cosmetics, it belongs to the category of cleansing and emulsifying agents found in shampoos, body washes, facial cleansers, and moisturizing lotions. It functions by reducing surface tension between oil and water phases, facilitating the removal of dirt, oils, and makeup during cleansing. Additionally, it stabilizes emulsions by forming a protective film at the interface, preventing separation and ensuring smooth, uniform product textures. Its mild nature suits rinse-off and leave-on formulations alike.
