  • Applications

    Undecasodium;2-[[3,4,5-tris(carboxylatomethoxy)-6-[[3,4,5-tris(carboxylatomethoxy)-6-[2,3,4,5-tetrakis(carboxylatomethoxy)-6-oxohexoxy]oxan-2-yl]methoxy]oxan-2-yl]methoxy]acetate (CAS 39422-83-8) is a highly anionic polycarboxylate salt used primarily as a chelating/sequestrating agent and dispersant. In household and industrial cleaners, it sequesters hardness ions and disperses soils to improve cleaning performance. It may be used as a scale inhibitor and metal-ion sequestrant in water treatment and cooling systems. In paints, coatings, and inks, it functions as a pigment dispersant and stabilizer, aiding pigment dispersion and rheology control. In polymers and plastics processing, it may act as a stabilizer/dispersant for inorganic fillers and pigments. In cosmetic/personal care formulations, it may be evaluated as a chelating additive to enhance formulation stability, pending regulatory compliance.
