  • Applications

    Potassium Glycolate, CAS 1932-50-9, is commonly used as a buffering and pH-adjusting component in cosmetics and personal care formulations, helping maintain stability and skin-friendly pH. It also functions as a chelating agent in household and industrial cleaners, sequestering trace metal ions to improve cleaning performance and reduce mineral deposits. In industrial manufacturing, it serves as an intermediate for the synthesis of glycolate derivatives and related polymers/plastics, supporting processing and formulation design. Additionally, it can act as a processing aid or anti-corrosion component in metalworking fluids and coatings, aiding metal ion balance and formulation compatibility.
