sodium polyphosphate is a preservative against bacteria, molds, and yeasts. When used in high concentrations, it can cause skin irritation.
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.
Sequestering and deflocculating agents, primar-
ily in water treatment, food processing, and cleaning
compounds; heavy-set detergent builders.
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.
Sodium hexametaphosphate is an inorganic polyphosphate salt commonly used as a corrosion inhibitor, emulsifying agent and as a tooth whitening agent in dentifrice formulations.
Intended for the cytologic demonstration of Naphthol AS-D Chloroacetate Esterase in blood, bone marrow films or tissue touch preparations.
