potassium pyrophosphate

Potassium pyrophosphate is an inorganic chemical compound primarily used in the dental and food industries. In oral care, it serves as an anti-calculus (anti-tartar) agent, where it functions by chelating and sequestering calcium and magnesium ions in saliva. This sequestration prevents the mineralization of dental plaque into hard calculus. Beyond its clinical use in dentifrices, it acts as a buffering agent, emulsifier, and stabilizer in food products, and is used in various industrial applications such as metal extraction, flame retardancy in polymers, and as a component in polishing slurries. Its safety and efficacy have been studied in subchronic toxicity models and clinical trials focusing on oral hygiene.
