Tri Sodium Phosphate 

Ever since our establishment in the year 1990, we have been engaged in importing, supplying and distributing quality assured Tri Sodium Phosphate (Na3PO4). It is an inorganic compound that is generally available in a white granular or crystalline solid form. This chemical salt is procured by neutralizing the phosphoric acid using sodium hydroxides with sodium carbonate.  This chemical compound gets soluble in water, thus producing an alkaline solution. As an alkaline agent has the powerful capacity to penetrate oil and grease, this tri sodium phosphate is popularly used in a variety of soaps, detergents, paint thinner, degreaser etc.
