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.

Sodium tripolyphosphate industrial grade water softener


1.The principle of sodium tripolyphosphate in softening water
Chelating effect: Combines with hardness ions such as Ca²⁺ and Mg²⁺ in water to prevent the formation of scale.
Dispersion effect: Prevent the deposition of formed scale layers and keep pipelines and equipment clean.
Corrosion inhibition effect: Forms a protective film on the metal surface to reduce corrosion.


2. Main application scenarios
Boiler water treatment
Prevent boiler scaling, improve thermal efficiency and extend equipment service life.

Applicable temperature: ≤80℃ (It is prone to decomposition at high temperatures and needs to be used in combination with other chemicals).

Industrial cooling circulating water
Reduce calcium and magnesium deposition in cooling towers, heat exchangers and pipelines.

It is suitable for medium and low hardness water (for high hardness water, other scale inhibitors need to be compounded).

Textile printing and dyeing industry
Soften the water quality, prevent dye sedimentation and improve the uniformity of dyeing.

Detergent and metal cleaning
Enhance the decontamination capacity and prevent hard water from affecting the cleaning effect.


3. Purchase suggestions
Select industrial-grade sodium tripolyphosphate (STPP) to ensure a purity of ≥94%.
Recommended dosage test: Conduct a small-scale test first, and then adjust the optimal dosage.
Supplier qualifications: Choose a regular manufacturer and provide MSDS and quality inspection reports.
