  • Applications

    Phosphoric acid, calcium potassium sodium salt (2:2:1:1) (CAS 131862-42-5) is a multi-cation phosphate salt used as a phosphate source and pH regulator in a range of industrial systems. In agriculture, it provides phosphate and supplements Ca and K for soils and crops. In cleaning and household products, it can act as a sequestering agent and water softener, improving the performance of detergents. In polymer and plastics processing, it can serve as a stabilizer or processing aid, helping to control pH and supply phosphate for synthesis. In cosmetics and personal care, it may function as a sequestering agent and stabilizer within formulations, improving product stability and uniformity. In water treatment and other industrial applications, it is used as a phosphate source and alkalinity adjuster to control scale formation and hardness. In coatings/inks, it can provide buffering and sequestering functions to improve formulation stability.
