  • Applications

    Quaternium-14 (CAS 14351-42-9) is a quaternary ammonium salt used primarily as a cationic surfactant and conditioning agent in cosmetics and personal care products (shampoos, conditioners, body washes). It typically acts as a surface-active ingredient to improve softness and manageability of hair and skin, and helps impart slip and texture to hair care formulations. In household cleaning products, it may serve as a surfactant in cleaners and detergents. In industrial applications, it is used as an additive in polymers and plastics to modify surface properties and can function as a wetting or dispersing agent in coatings, inks, and adhesives, depending on formulation and local regulations.
