  • Applications

    Olealkonium chloride (CAS 37139-99-4) is a cationic surfactant with an oleyl chain used as an emulsifier, conditioning agent, and additive in a range of industrial applications. In cosmetics and personal care, it acts as a surfactant and conditioning agent for hair, imparting smoothness and detangling properties. In household cleaning and fabric-care products, it serves as a surfactant and conditioning additive in detergents and fabric softeners. In industrial manufacturing, it is used as an emulsifier, wetting agent, and dispersant for coating systems, inks, and polymer formulations, improving blend compatibility and dispersion of difficult components. In polymer and plastic processing, it can function as an emulsifier and stabilizer for polymer emulsions, aiding uniformity and stability of the mixture.
