Tri-potassium citrate monohydrate is the common tribasic potassium salt of citric acid, also known as potassium citrate. It is produced by complete neutralisation of citric acid with a high purity potassium source and subsequent crystallisation. In pharmaceuticals it is used as potassium source and as active ingredient to treat urinary duct stones. When added to oral care products, tripotassium citrate is the active ingredient to reduce the sensitivity of the teeth.
