Product Uses

In detergents

The majority of STPP is consumed as a component of commercial detergents. It Serves as a "builder, " industrial jargon for a water softener. In hard water (water that contains high concentrations of Mg2+ and Ca2+), detergents are Deactivated. Being a highly chargedchelating agent, TPP5- binds to dications.Tightly and prevents them from interfering with the sulfonate detergent. 

Food applications

STPP is a preservative for seafood, meats, poultry, and animal feeds. It is common In food production as E number E451. In foods, STPP is used as an emulsifier and to retain moisture. Many governments regulate the quantities allowed in foods, as It can substantially increase the sale weight of seafood in particular. The United States Food and Drug Administration lists STPP as "generally recognized as safe.". 

Other uses

Other uses include "ceramics, leather Tanning(as masking agent and synthetic tanning agent - SYNTAN), anticaking, Setting retarders, flame retardants, paper, anticorrosion pigments, textiles, Rubber manufacture, fermentation, antifreeze. 

In total,Sodium tripolyphosphate has the functions of chelating, suspending, dispersing, peptizing, emulsifying, and pH buffering. It can be used as the main additive for synthetic detergents, industrial water softeners, leather pretanning agents, dyeing auxiliaries, and organic synthesis catalysts. , pharmaceutical industry dispersants and food additives, etc. In addition to exporting 9 STPP, domestic STPP consumption is mainly concentrated in the detergent industry, food, ceramics, etc.
