  • TPC is known as tripotassium citrate monohydrate (C6H5K3O7 • H2O ) which is the common tribasic potassium salt of citric acid, also known as potassium citrate. It is produced by complete neutralization of citric acid with a high purity potassium source, and subsequent crystallization.
  • Tripotassium citrate occurs as transparent crystals or a white, granular powder. It is an odorless substance with a cooling, salty taste. It is slightly deliquescent when exposed to moist air, freely soluble in water and almost insoluble in ethanol (96%).
  • Tripotassium citrate is a non-toxic, slightly alkaline salt with low reactivity. It is chemically stable if stored at ambient temperatures. In its monohydrate form, TPC is very hygroscopic and must be protected from exposure to humidity. Care should be taken not to expose tripotassium citrate monohydrate to high pressure during transport and storage as this may result in caking. Tripotassium citrate monohydrate is considered “GRAS” (Generally Recognized As Safe) by the United States Food and Drug Administration without restriction as to the quantity of use within good manufacturing practice. CAS Registry Number:[6100-05-6], E-Number: E332.
