Dipotassium Hydrogen Phosphate (also known as dipotassium phosphate, DKP) is an inorganic salt used widely as a buffering agent, emulsifier, and nutritional supplement in various industries. It is a white, crystalline, highly water-soluble powder with alkaline properties. DKP plays a vital role in food processing, pharmaceuticals, water treatment, and agriculture due to its ability to stabilize pH, improve texture, and supply essential potassium and phosphate ions.
