Polyoxyethylene behenyl ether

Polyoxyethylene behenyl ether (CAS 26636-40-8), commercially known as Beheneth, is a long-chain ethoxylated fatty alcohol derived from behenic acid.

Where is Polyoxyethylene behenyl ether used?

• Personal care: nonionic surfactant and emulsifier
• Cosmetics: stabilizes oil-in-water emulsions in creams, lotions and conditioners
• Hair care: conditioning agent and emulsion stabilizer in rinse-off and leave-in products
• Home care and industrial cleaning: wetting and dispersing agent that improves soil removal in hard surface cleaners and detergent concentrates
• Textile and leather processing: modifies fiber surface tension during dyeing and finishing
• The C22 chain length delivers substantivity to the hair shaft.

Good to know: Common commercial grades are designated by ethylene oxide chain length, such as Beheneth-5, Beheneth-10, and Beheneth-20; each grade targets different HLB requirements.
