Sodium polyphosphate Chemical Properties,Uses,Production

Uses

Sequestering and deflocculating agents, primar- ily in water treatment, food processing, and cleaning compounds; heavy-set detergent builders.

Uses

sodium polyphosphate is a preservative against bacteria, molds, and yeasts. When used in high concentrations, it can cause skin irritation.

Uses

Sodium hexametaphosphate has been used as a polyphosphate anion source to prepare hydrated calcium polyphosphate powder. It can be used as a deflocculant to prepare suspensions of kaolinite and ceramic grade kaolin.

Definition

The two most important crystalline sodium polyphosphates are the pyrophosphate (n = 2) and the tripolyphosphate, also called the triphosphate (n = 3). The term sodium polyphosphate also includes the system of vitreous sodium phosphates for which the mole ratio of Na2O/P2O5 is between 1 and 2.

General Description

Sodium hexametaphosphate is an inorganic polyphosphate salt commonly used as a corrosion inhibitor, emulsifying agent and as a tooth whitening agent in dentifrice formulations.

Hazard

As for sodium phosphate.

Biochem/physiol Actions

Intended for the cytologic demonstration of Naphthol AS-D Chloroacetate Esterase in blood, bone marrow films or tissue touch preparations.
