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. It functions as a nonionic surfactant and emulsifier across personal care, cleaning, and industrial formulations.

In cosmetic formulations, it stabilizes oil-in-water emulsions in creams, lotions, and conditioners while contributing a smooth skin feel that supports moisturizing performance. This ingredient is valued for its high stability and compatibility.

Hair care manufacturers use it as a conditioning agent and emulsion stabilizer in rinse-off and leave-in products. The C22 chain length delivers substantivity to the hair shaft, improving manageability and texture in professional hair treatments.

In home care and industrial cleaning products, it acts as a wetting and dispersing agent. It improves soil removal in hard surface cleaners and detergent concentrates, ensuring effective performance in various aqueous environments.

Textile and leather processing operations use it to modify fiber surface tension during dyeing and finishing. This ensures even dye uptake and consistent coating adhesion, which are critical for high-quality industrial textile production.

Polyoxyethylene behenyl ether is supplied as a waxy solid, flakes, or paste depending on the degree of ethoxylation. 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 for specific formulation needs. Cosmetic-grade material conforming to standard industry purity specifications is the most commonly traded form for global manufacturing and distribution.
