  • Applications

    ethylenediamine-N,N'-disuccinic acid (CAS 20846-91-7) is a biodegradable chelating agent used to sequester metal ions across a range of industrial and consumer formulations; in household and industrial cleaning products it functions to stabilize formulations by binding calcium and magnesium ions, improving cleaning performance; in cosmetics and personal care it serves as a chelating agent to prevent metal-catalyzed oxidation and preserve product stability; in agriculture it is used as a micronutrient chelate and fertilizer additive to improve availability of metals such as iron, zinc, and manganese; in coatings and inks it helps stabilize pigments and mitigate metal-related color changes; in polymer and plastics processing it acts as a stabilizer or processing aid to minimize metal-catalyzed degradation during polymerization or dyeing; in water treatment and industrial manufacturing it may be evaluated as an environmentally friendlier alternative to traditional chelators.
