68915-31-1 Usage
Description
Sodium polyphosphate is an inorganic polyphosphate salt that exists in various forms, including pyrophosphate (n=2) and tripolyphosphate (n=3). It is characterized by a mole ratio of Na2O/P2O5 between 1 and 2 and is known for its diverse applications across different industries.
Uses
Used in Water Treatment, Food Processing, and Cleaning Compounds:
Sodium polyphosphate is used as a sequestering and deflocculating agent to improve the efficiency of these processes. Its ability to bind and remove impurities makes it a valuable component in these industries.
Used in Detergent Industry:
Sodium polyphosphate is utilized as a heavy-set detergent builder, enhancing the cleaning power and effectiveness of detergent formulations.
Used in Preservation:
Sodium polyphosphate serves as a preservative against bacteria, molds, and yeasts, particularly in the food processing industry. However, it is worth noting that high concentrations may cause skin irritation.
Used in Ceramics and Kaolin Preparation:
Sodium hexametaphosphate, a related compound, is used as a polyphosphate anion source to prepare hydrated calcium polyphosphate powder. This powder acts as a deflocculant in the preparation of suspensions of kaolinite and ceramic grade kaolin, which are essential materials in the ceramics industry.
Used in Dentifrice Formulations:
Sodium hexametaphosphate is also employed as a corrosion inhibitor, emulsifying agent, and tooth whitening agent in dentifrice formulations, contributing to improved oral health and hygiene.
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.
