BEHENETH-10.

Valuable CAS 26636-40-8 / SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

A high-performance non-ionic polyether of behenyl alcohol that functions as a sophisticated oil-in-water emulsifier and stabilizer. It is prized in precision skincare for its ability to create elegant, velvety textures while simultaneously acting as a delivery vehicle for active molecules.

Science

Beheneth-10 operates as a surface-active agent that lowers interfacial tension to stabilize complex oil-in-water emulsions. Mechanistically, it also serves as a penetration enhancer by modulating the skin barrier's permeability, allowing co-formulated active ingredients to reach their target layers more efficiently while providing a smooth, non-greasy skin feel.
