Trisodium phosphate

Trisodium phosphate (CAS 7601-54-9 ), commonly abbreviated as TSP and approved as food additive E339iii , is an inorganic phosphate salt used across industrial and food-grade applications for pH control and sequestration. Tribasic sodium phosphate is the recognized alternative name buyers encounter in technical specifications and regulatory documents. In industrial cleaning, TSP functions as a heavy-duty degreaser for metal and concrete surfaces. Food and beverage manufacturers use it as a buffering and sequestering agent in processed cheeses, cured meats, and cereal products. It helps to control acidity and bind metal ions that would otherwise accelerate spoilage. Water treatment facilities dose TSP to adjust pH and inhibit scale formation in boiler and cooling water systems. In textile and paper processing, it acts as a scouring aid and assists in flame-retardant formulations. Trisodium phosphate is supplied as a white crystalline powder or granules, with anhydrous and dodecahydrate forms both available commercially. Standard grades include food-grade ( FCC ), technical grade, and USP . Food-grade material meets purity thresholds required for direct food contact applications. Bulk supply is typical for industrial buyers, with smaller packaging available for laboratory or specialty formulation use. Contact us for supply of Trisodium phosphate Request Quote
