  • Applications

    Ammonium Myristyl Sulfate (CAS 52304-21-9) is an anionic surfactant commonly used in cosmetics and personal care products such as shampoos, facial cleansers, and body washes to provide cleansing, foaming, and emulsification; it also serves as a surfactant and foaming agent in household and industrial cleaning formulations; in coatings and inks, it acts as an emulsifier and wetting agent to improve spreading and pigment dispersion; in agricultural formulations it may be used as an adjuvant to enhance wetting and spray coverage; and in polymer and latex formulations it can function as a processing aid and emulsifier to stabilize disperse systems.
