Potassium Tripolyphosphate (CAS 13845-36-8) is a highly water-soluble inorganic salt, the pentapotassium salt of triphosphoric acid, supplied in Food Grade and Technical Grade as a white crystalline powder that acts as a chelating agent and emulsifier in concentrated liquid detergents and helps stabilize protein-based foods. This hygroscopic white powder provides superior buffering capacity and prevents scale formation in industrial water systems. It is highly valued for its ability to sequester metallic ions and stabilize protein-based food products. The compound is essential for high-solids cleaners where sodium salts might precipitate. It functions as a high-efficiency dispersing agent in ceramic, textile, and specialized surface treatment applications.
