Beheneth-20
What is Beheneth-20?
Beheneth-20 is polyoxyethylene (20) behenyl ether, a synthetic non-ionic surfactant made by ethoxylating behenyl alcohol, a C22 fatty alcohol sourced from vegetable oils such as rapeseed. It serves primarily in rinse-off and leave-on cosmetics like shampoos, conditioners, body washes, lotions, and creams. By reducing interfacial tension, it stabilizes oil-in-water emulsions, promotes even dispersion of ingredients, and supports mild foaming and cleansing actions. This functionality ensures products spread smoothly, rinse cleanly, and maintain consistency without disrupting the skin's lipid barrier, making it ideal for everyday personal care formulations focused on hydration and texture.
