  • Applications

    Zinc Lauroyl Aspartate (CAS 899426-42-7) is used in cosmetic and personal care formulations as a mild surfactant and emulsifier, helping to cleanse, stabilize emulsions, and improve texture in cleansers, shampoos, and creams, with the zinc cation contributing potential metal-chelating benefits in formulations. It also serves as a conditioning agent and texture enhancer in skincare and haircare products. In household cleaning products, it acts as a surfactant/emulsifier to enhance soil removal and formulation stability. In coatings and inks, it can function as a emulsifier or stabilizer for pigment dispersions, promoting better pigment compatibility and gloss. In polymers and plastics processing, it may be used as a processing aid to improve formulation compatibility and stability, while its chelating properties can aid in metal ion management in various systems.
