Sodium tripolyphosphate/ STPP

​Industrial grade 96% CAS 7758-29-4

Food grade 85% CAS 7758-29-4

Molecular formula Na5P3O10

Molecular weight 367.86

【 Performance Characteristics 】

White granular or powder, showing a density of 0.35-0.90G/CM3, melting point 622 degrees Celsius.

It is easily soluble in water, the aqueous solution is alkaline, and the PH of 1% aqueous solution is 9.7.

It is gradually hydrolyzed into phosphite in water, and has good ionic ability of metal complexation.

It can be complexed with calcium/magnesium/iron and

other metal ions to produce soluble complexes. It softens hard water. As a kind of inorganic surfactant,

it has some properties of organic surfactant.

【 Purpose 】

Mainly used for synthetic detergent as an additive/soap agent and to prevent bar soap grease precipitation and

frosting. It has a strong emulsifying effect on lubricating oil and fat, and can be used to

adjust the PH value of buffer soap liquid, industrial water softener/tanning and

pre-tanning agent/dyeing agent/paint/kaolin/magnesium oxide/calcium carbonate and

other industries to prepare suspension as a dispersant, drilling mud dispersant,

and paper industry as an anti-oil agent.

Is sodium tripolyphosphate good for water treatment


1.The role of sodium tripolyphosphate in water treatment
Scale inhibitor
It can chelate with metal ions such as calcium and magnesium in water, preventing scaling (such as in boilers and cooling water systems), and is especially suitable for high-temperature or high-hardness water quality.

Corrosion inhibitor
It forms a protective film on the surface of metal pipes or equipment to slow down corrosion (often used in combination with other corrosion inhibitors).

Dispersant:
Prevent the deposition of suspended particles and keep the system clean (such as industrial circulating water, pretreatment of reverse osmosis membranes).


2. Advantages vs. Limitations
Advantages:

Low cost and high cost performance;

It has strong chelating ability and is suitable for water with medium and low hardness.

It has both corrosion inhibition and dispersion effects.

Limitations:

Environmental protection issues: It contains phosphorus and is prone to cause eutrophication of water bodies (its use is restricted in some countries/regions).

High-temperature failure: Decomposition may occur when the temperature exceeds 80℃, reducing the effectiveness.

Dosage control is required: Excessive use may leave residues and affect subsequent processes.


3. Suggestions for applicable scenarios
Recommended for use

Industrial circulating cooling water system

Water treatment for small boilers

Wastewater treatment without strict phosphorus restriction (such as the pretreatment stage).

Not recommended for use

Environmentally friendly areas with strict phosphorus bans;

High-temperature (>80℃) or extremely high-pressure systems;

Drinking water treatment (must be food-grade and meet safety standards).
