  • Applications

    Potassium adipate (CAS 19147-16-1) is the potassium salt of adipic acid and is used in formulations as a buffering salt and chelating agent. In cosmetics and personal care, it helps adjust pH and maintain formulation stability. In household and industrial cleaners, it acts as a chelating/sequestering agent to bind trace metal ions and improve surfactant performance. In polymer, coatings, and ink systems, it serves as an ionic-strength modifier and stabilizer, helping control rheology and metal-ion interactions. In industrial manufacturing, it can function as an intermediate or processing aid for resin and plastic formulations, and may be used as a precursor to other adipate derivatives. Its use is formulation-dependent and subject to local regulations and limits.
