  • Applications

    Sodium caproyl proline (CAS 1364318-34-2) is commonly used as an amino-acid-derived surfactant, functioning as a surface-active agent and emulsifier in cosmetic and personal care formulations, where it can act as a mild cleanser and conditioning-type ingredient. In addition, it may be used in household cleaning products and detergents due to its gentle profile. In industrial manufacturing, it can serve as a surfactant or emulsifier for polymer processing, coating formulations, and inks, helping stabilize emulsions and improve compatibility. It can also be considered as a processing aid or additive in polymers/plastics and as a compatibilizer in coatings to improve wetting and dispersion. The compound is typically used in formulated products subject to local regulations and formulation limits.
