Tetrapotassium Pyrophosphate (TKPP) is a potassium-based pyrophosphate salt similar to its sodium counterpart. It functions as a buffering agent, emulsifier, and chelating agent. TKPP is used in detergents, food processing, and various industrial applications. It provides the additional benefit of potassium content, making it suitable for low-sodium formulations and potassium-fortified products.
