Product Description

Product Description
 

Property:White powder, easily soluble in water but insoluble in ethanol; Density at 2.45g/cm³ and melting point at 890ºC; Deliquescent in the open air. The water solution shows weak alkalinity and stable at 70ºC, but will be hydrolyzed into disodium phosphate when boiled.

Food Grade Tetra Sodium Pyrophosphate(TSPP)application:.
Uses: Totally,mainly used as in food as buffering agent,  emulsification agent, and nutrition ingredients , and quality improver, etc.
In details
For Canned fruit,together with other phosphate(pryphosphate,metaphosphate,orthophosphate) as chelating agent to improve quality;

For Cheese,as melten solvent and emulgator to release calcium(Usage no more than 0.9%)

For Soy source,to improve color and lustre by preventing browning.


For Canned fruit.
Food grade TSPP could be used as complex with Ca2+,Mg2+,Fe2+,Cu2+ to form colorless complex and avoid color change to improve the appearance.

Tech grade TSPP is used in electroplating industry to prepare electroplating solution, which can form complex with iron.

Used in wool industry as degreaser and bleaching agent for wool.

Used in the paper industry to bleach paper and plant fibers. Printing and dyeing industry used as auxiliaries in dyeing and finishing bleaching. Daily chemical industry used as toothpaste additive, can form colloid with calcium hydrogen phosphate and play a stable role, can also be used in the synthesis of detergent and the production of shampoo cream products.

Used as water softener in water treatment.

Used as a rust remover in machining. It is used as dispersant and emulsifier in chemical production.

Can also be used in water treatment agent, oil drilling and other aspects, in the food industry as quality improver, emulsifier, buffer, chelating agent, etc. Sodium pyrophosphate has the function of softening water, but also can dissolve calcium, magnesium insoluble salts, such as clothing fibers, mixed with insoluble calcium soap or other metal soap formed dirt, it can make its redissolve and improve the decontamination ability.

In addition, sodium pyrophosphate has the effect of reverse flocculation, so that oil emulsification, which is called the gelolytic property. It can also make the surfactant solution further reduce the surface tension and interfacial tension, and play the role of washing aid.
