Ingredient Information

Function

Sodium polyphosphate is also known as Graham’s salt. It is used as an acidity regulator, emulsifier and buffering agent in dough and flour mixes, and as a sequestering agent in potatoes and meat. It also stabilizes the emulsifying fats and is used as a thickening agent in ice creams, puddings, ice milks, artificial jelly mixes and breakfast cereals.

Sodium polyphosphate is used in the processing of ice milk, processed cheese, canned seafood, meat, bottled beverages and pet foods.

Other Use and Industries

Sodium polyphosphate, also known as glassy, is used in water supply services.

It is also used in toothpastes, ceramics and cosmetics manufacturing.

Health Effects

Too much sodium polyphosphate could lead to kidney damage or kidney stones by sticking to the calcium ions in water. It may also cause skin irritation on direct contact.

Although phosphates contribute in the metabolic mechanism of the body, high concentrations of sodium phosphates may disturb the metabolic processes.

Those who are pregnant or who have heart disease or diabetes should limit consumption of sodium polyphosphate due to its sodium content.

Origins

Sodium polyphosphate is another general term for sodium hexametaphosphate. It has the molecular formula of Na3O10P3X2. It occurs as a white, colorless powder or in the form of white, glassy fragments or lumps.
