Tetrapotassium Pyrophosphate (TKPP) is used for its properties as a food and toothpaste additive, buffering agent, dispersing agent, protein modifier, and mineral supplement to name a few uses. In pet food, TKPP is used to modify proteins enabling them to solubilize and retain moisture during storage. TKPP is also used in milk, cheese, and meat processing. TKPP has proven itself in oral care as an effective anti-tartar compound.
