  • Applications

    Potassium glycerophosphate (CAS 1319-69-3) is typically used as a buffering salt and a source of potassium and phosphorus in a range of formulations. In industrial manufacturing and biochemical processing, it can act as a pH-stabilizing additive and may function as a chelating or stabilizing agent to support enzyme activity and formulation integrity. In agriculture and horticulture, it provides a phosphorus and potassium source for plant nutrition, including hydroponic applications. In animal nutrition and feed, it serves as a mineral supplement to help meet phosphorus and potassium requirements. In cosmetics and personal care, it is used as a buffering agent and stabilizer to control pH and product stability. In household cleaners, it may be employed as a buffering or sequestering component to improve formulation stability and performance. The actual usage is subject to regional regulations and formulation constraints.
