  • Applications

    Lauryl aspartic acid, L- is mainly used as a surfactant and a building block in cosmetic and personal care formulations, contributing mild cleansing and foaming properties. It is also employed in household cleaning products as part of surfactant systems to enhance detergency and emulsion stability. In industrial manufacturing, it serves as a specialty surfactant and dispersant and as a starting point for synthesizing other surfactants and polymer processing aids. In coatings and inks, it can act as a dispersant or wetting agent to improve pigment dispersion and substrate wetting. As an amino-acid-derived acid derivative, it is sometimes evaluated for use in polymer formulations and as a processing aid to improve formulation compatibility and handling.
