PPG-8-Ceteth-20

What is PPG-8-Ceteth-20?

PPG-8-Ceteth-20 is a non-ionic surfactant derived from cetyl alcohol ethoxylated with eight propylene glycol units and 20 ethylene oxide groups. This synthetic ingredient belongs to the polyether category, commonly found in rinse-off products like shampoos, body washes, and facial cleansers, as well as leave-on formulations such as lotions and creams. It functions by reducing surface tension between oil and water, enabling effective emulsification to form stable blends with smooth textures. As a surfactant, it supports foaming and cleansing actions by helping remove dirt and oils without harsh stripping. Its hydrophilic-lipophilic balance allows it to solubilize fragrances and oils in water-based systems, contributing to product clarity and spreadability. In cosmetic formulations, it enhances overall performance by stabilizing emulsions and improving rinse-off properties.
