  • Applications

    Potassium Cetyl Phosphate (CAS 84861-79-0) is an anionic surfactant used as an emulsifier and stabilizer in a range of formulations. Common applications include cosmetic and personal care products such as shampoos, facial cleansers, and body washes, where it acts as a surfactant and emulsifier to improve foaming, cleansing performance and formulation stability. It is also used in household and industrial cleaning products like detergents and cleaners, providing wetting, emulsification and soil removal capabilities. In coatings, inks, and polymer formulations, Potassium Cetyl Phosphate can serve as a surfactant to improve pigment dispersion, surface wetting, and emulsion stability. Additionally, it may function as a surfactant/dispersion aid in specialty cleaning formulations and industrial processes, depending on formulation needs and local regulatory requirements.
