Beheneth-5

What is Beheneth-5?

Beheneth-5 is a non-ionic surfactant derived from behenyl alcohol, a long-chain fatty alcohol sourced from natural vegetable oils like rapeseed, chemically modified through ethoxylation with five ethylene oxide units. This process creates a hydrophilic head and hydrophobic tail, allowing it to function effectively in personal care formulations. Commonly found in shampoos, body washes, lotions, and hair conditioners, it reduces surface tension to facilitate dirt removal and stabilizes emulsions by forming a protective film around oil droplets in water-based systems. Its gentle nature supports clear, non-separating products without heavy residues, contributing to lightweight feel and easy rinsing in rinse-off applications.
