Sodium pyrophosphate decahydrate is used as a buffering agent, an emulsifier, a thickening agent, a food additive and a dispersing agent. It acts as a tartar control agent in tooth paste and dental floss and is used to remove calcium and magnesium from saliva, thereby avoiding its deposition on teeth. It is utilized in detergents to prevent deposition on cloth. It is useful in the preparation of an EDTA-sodium pyrophosphate extraction buffer for microcystin analysis of soil samples. In antimicrobial studies, it is used as a chelating agent.
