  • Applications

    Behenyl Betaine (CAS 26920-62-7) is a long-chain alkyl betaine surfactant commonly used as a conditioning surfactant and foam booster in cosmetics and personal care products, including shampoos, conditioners, and body washes. It also functions as a thickener, emulsifier, and texture enhancer in these formulations. In household and industrial cleaning products, it serves as a mild surfactant and stabilizer to improve cleaning performance and formulation compatibility in detergents, dish liquids, and surface cleaners. In broader manufacturing contexts, it may be evaluated or used as an emulsifier or surfactant additive for polymer, coating, and ink formulations, helping to stabilize emulsions and improve compatibility with other ingredients.
