What is Trideceth-12?

Trideceth-12 is a nonionic surfactant derived from tridecyl alcohol ethoxylated with 12 moles of ethylene oxide, creating a hydrophilic molecule with a hydrophobic tail. This structure allows it to function in personal care products like shampoos, body washes, facial cleansers, and moisturizing lotions. In formulations, it reduces surface tension between water and oils, enabling dirt, oils, and makeup removal during cleansing. As an emulsifier, it stabilizes mixtures by forming micelles that encapsulate hydrophobic substances, preventing separation and ensuring smooth textures. Commonly found in rinse-off and leave-on products, it supports foaming in washes and uniform dispersion in creams, contributing to product efficacy without residue buildup.
