  • Applications

    l-aspartic acid, n-(3-carboxy-1-oxo-2-sulfopropyl)-n-octadecyl-, tetrasodium salt is an anionic surfactant with a long hydrophobic octadecyl tail and sulfonate/carboxylate groups, typically used as an emulsifier, wetting agent, and dispersant in detergents and household cleaners; it is also commonly added to cosmetics and personal care formulations as a surfactant, and in industrial settings it serves as a pigment dispersant and stabilizer in paints, coatings, and inks; in polymer and plastics processing it can function as a processing aid to improve dispersion and compatibility of additives; in textile processing it may act as a wetting or leveling agent during dyeing.
