Tripotassium phosphate

Tripotassium phosphate ( CAS 7778-53-2 ), also known as potassium phosphate tribasic and approved as E340iii , is a highly alkaline inorganic salt used across food, industrial, and pharmaceutical manufacturing. It functions primarily as a pH regulator, buffering agent, and sequestrant in formulations where precise alkalinity control and mineral chelation are required for stability and performance. In food processing, E340iii adjusts pH and acts as an emulsifying salt in processed cheeses, meat products, and beverage formulations. Water treatment operations use it to inhibit scale formation. It is also used to sequester hardness minerals in boiler and cooling systems. Textile and paper processing facilities apply it as a flame retardant treatment and pH modifier during fiber preparation. In pharmaceutical manufacturing, it serves as a buffering excipient in liquid formulations and cleaning-in-place (CIP) solutions where controlled alkalinity is critical for maintaining equipment hygiene. Tripotassium phosphate is supplied as a white crystalline powder or granules, with anhydrous and monohydrate forms available. Recognized grades include food-grade ( FCC ), USP , and technical-grade. Each grade carries distinct purity thresholds suited to their respective end markets. Bulk supply is standard for industrial buyers, with food and pharma grades requiring documented quality specifications. Certificates of analysis are provided to ensure compliance with global safety standards. This versatile chemical remains a staple for manufacturers requiring reliable pH control and mineral management. Contact us for supply of Tripotassium phosphate Request Quote
