  • Applications

    Sodium lauroyl methylaminopropionate (CAS number: 21539-58-2) is a mild surfactant commonly used as a surface-active agent, emulsifier and foaming aid in personal care formulations such as shampoos, cleansers, and body washes, providing cleansing performance with skin-friendly properties. It is also employed in household cleaning products, including liquid detergents and dishwashing formulations, where it contributes to wetting, emulsification and stable formulations. In industrial manufacturing, the compound serves as a surfactant and emulsifier in polymer and coating systems to improve pigment dispersion and formulation stability. It can function as a processing aid in polymers and latex formulations, and may be evaluated as a formulation aid or adjuvant in agricultural and pharmaceutical topical products, subject to local regulations and formulation limits.
