68915-31-1 Usage
Uses
Different sources of media describe the Uses of 68915-31-1 differently. You can refer to the following data:
1. Sequestering and deflocculating agents, primar-
ily in water treatment, food processing, and cleaning
compounds; heavy-set detergent builders.
2. sodium polyphosphate is a preservative against bacteria, molds, and yeasts. When used in high concentrations, it can cause skin irritation.
3. 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.
Check Digit Verification of cas no
The CAS Registry Mumber 68915-31-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,9,1 and 5 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 68915-31:
(7*6)+(6*8)+(5*9)+(4*1)+(3*5)+(2*3)+(1*1)=161
161 % 10 = 1
So 68915-31-1 is a valid CAS Registry Number.
