  • Applications

    Tetrasodium dicarboxymethyl aspartate (CAS 34612-80-1) is a multi-carboxylate chelating agent used as a stabilizer, dispersant, and metal-sequestering additive across several industries. In household and industrial cleaners, it chelates hardness minerals to improve stain removal and formulation stability. In cosmetics and personal care, it functions as a chelating agent to enhance product stability and prevent metal-catalyzed degradation. In polymers, plastics, coatings, and inks, it acts as a dispersant and processing aid to improve pigment dispersion and formulation stability. In water treatment and process fluids, it can serve as a scale inhibitor and metal ion sequestrant to reduce precipitation and corrosion. In some applications, it may be used as an intermediate or additive within broader formulation blends.
