General Information

Its chemical formula is Na4P2O7 * 10 H2O. The aqueous solution is alkaline and easily soluble in water. The pH of the 1% solution ranges from 10 to 11.

Production and Reactions
Tspp is a sodium salt and is derived from its carbonate and phosphates, such as tkpp.

Usage areas

food
As a source of phosphorus, TSPP is an emulsifier which is used for the binding of soybean particles and protein water connection. It is also used as a thickener in ready puddings.

Textile

It is used as an inorganic stabilizer in textile.

Detergent
As a water softener for detergents, it can be used as an emulsifier to suspend the oils and to prevent their sedimentation on the laundry in the wash.

Chemistry
It is used as ph value adjuster in chemical industry.

Tooth paste
Since they remove Ca and Mg ions from saliva, they do not stay on the teeth so they are used as buffer in toothpastes.
