STPP is known as Sodium Tripolyphosphate. It is commonly used in the manufacture of synthetic detergents, water treatment, and other sectors such as ceramics, food and beverage, paint and varnish, etc. It is a white molecular mineral and is used as a binder, stabilizer and sequestrant. We get our STPP mineral from several regions of Rajasthan in India.
STPP has several applications in the food and beverage industry. Cake mixtures, meringues, juices, hams, peas, lima beans, cured pork, sausages, and algin sweets all contain this ingredient. Within the ceramic and enamel industry, STPP mineral is used to achieve a fluid paste or a well-dispersed solution which further optimizes the manufacturing process.
Sodium triphosphate is a solubilizing binder found in powder detergents, automatic dishwashing powder/tablets, and other cleaning solutions. It is particularly effective in treating water hardness by inactivating the mineral ions and keeping them securely in the solution. It permits surfactants to perform to their maximum extent by fighting water hardness. It also functions as a pH buffer and prevents soil from resettling on the garments. This makes it the most perfect mineral in the laundry detergents, dishwashing powder and in the tanning of leather.
Sodium triphosphate (STP), also sodium tripolyphosphate (STPP), or tripolyphosphate (TPP), is an inorganic compound with formula Na5P3O10.
Furthermore, it is also popularly used in the paper and coatings industry to remove the pitch spots. They are created by a kind of gum present in the wood pulp which can cover the whole surface and create dents on the surface of the paper.
This natural mineral is magmatic in nature and has a high phosphorus concentration and very low heavy metal levels. As a result, our STPP mineral has a high purity level which enhances the performance of whatever end-product it is utilised in.

White powder, apparent density:0.35-0.90g/ml, melting point: 622�°C, easily dissolving in water; water solution is alkaline (PH value of 1% solution is 9.7); can hydrolyze into phosphate in water, has good ability in complexing metal ions; can be used to soften water; has some surfactant properties. 1.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 charged chelating agent, TPP5- binds to dictations tightly and prevents them from interfering with the sulfonate detergent. 2.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.". 3.Other Uses Other uses (hundreds of thousands of tons/years) 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.
Sodium tripolyphospahte as STPP, it is a white inorganic salt,which exists both in granular and powder. The majority of sodium tripolyphosphate is consumed as a component of commercial detergent, which serves as a "builder" or industrial jargon for a water softener. It is also widely used in ceramic,leather tanning,paper production,textile,rubber manufacture,etc.

Stpp (sodium tripolyphosphate) Properties: White powder; melting point 622ípc; easily soluble in water; it has got salient chelating capacity to ions of ca and mg etc. And can soften hard water to make suspension solution become into clear solution; it has got weak alkalinity but no corrosiveness. It is a surfactant, and has got outstanding emulsification to lubricants and fat. It has different bulk density, i.E. Low density 0.35-0.5g/cm3, medium density 0.51-0.65g/cm3 and high density 0.66-0.9g/cm3. This product has two crystalline forms, namely type i (high temperature type) and type ii (low temperature type). The chemical properties of the two types are the same, and the difference between them lies in the thermostability, hygroscopicity, and solubility and hydration heat when dissolving.
