Brief Overview
Sodium tripolyphosphate, also called STPP, or sodium triphosphate, is an inorganic chemical compound, represented as Na5P3O10. It is a white powder and comes in an anhydrous form as well as a hexahydrate form. It has a wide range of applications, but it is majorly used in the detergent industry because it binds strongly to metal as both a bidentate and tridentate chelating agent. Although it is used widely, there are concerns raised in the widespread use of it as a detergent, as it leads to eutrophication.

Manufacturing Process
STPP may be manufactured in two ways:

  • Molecular dehydration of mono & disodium phosphates:

                                                2 Na2HPO4 + NaH2PO4 → Na5P3O10 + 2 H2O

Through this reaction, 2 million tonnes of STPP is produced annually.

  • Controlled calcination of sodium orthophosphate mixture from sodium carbonate & phosphoric acid

                                                     

Detergent Industry
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 charged chelating agent, TPP5- binds to di-cations tightly and prevents them from interfering with the sulphonate detergent.

Paper Industry
It is used as a coating agent for paper due to its ability to disperse in water and hence it coats the paper white in colour. It also acts as an oil contamination resistance agent and a defending grease agent in paper production. It also acts as a pitch control agent in raw paper pulp in the grinding or washing stages of wood pulp production, by adsorbing the residual resins and other contaminants which impact the productivity of paper mills and the quality of the paper from the wood pulp. It is used as a de-inking process of newsprint.


Food Industry
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 such as that in cheese production.

Other Applications
STPP is also used as a seal for leaking farm ponds by mixing with soil floor, hydrogen peroxide stabilizer, and dairy substitute for milk-based pudding, whipped topping, sour cream, and cheese.
