Description
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.

Soluble in water
Oral-Rat LD50: 3053 mg/kg; Oral-Mouse LD50: 7572 mg/kg
In case of H, the pore-forming agent is combustible; it decomposes toxic phosphorus oxide fumes when heated
Between 3,7 and 5,0 (1 % solution)
Safety Information
NONH for all modes of transport
