  • Applications

    Behenalkonium chloride, CAS 16841-14-8, is a cationic quaternary ammonium surfactant primarily used for conditioning and surface feel. In cosmetics and personal care, it is commonly employed as a surfactant and conditioning agent to improve manageability and softness in products such as shampoos, conditioners, and facial cleansers. It also serves as an emulsifier, stabilizer, and dispersing aid in cosmetic formulations for emulsions. In household and light industrial applications, it acts as a surfactant and fabric-softening additive in laundry and cleaning products, enhancing spreading and leave-on softness. In industrial manufacturing, it may be used as a surface-active additive in coatings, inks, and adhesives to improve wetting, dispersion, and slip. Use is subject to local regulations and formulation limits.
