Description
Trisodium phosphate 0AQ (anhydrous) is a widely used inorganic phosphate. The product occurs as a white, crystalline, odorless powder and comes in the anhydrous form (0AQ = 0 aquae), which means it contains no crystalline water. Trisodium phosphate is known for its strong alkaline properties, high water solubility and wide applicability in various industrial sectors. It is widely used as a detergent, water softener, emulsifier and pH regulator.
