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.
High purity and stability
≥96% industrial-grade content, extremely low impurities, stable and reliable performance
powerfully softens water
Rapidly chelate calcium and magnesium ions to enhance the efficiency of cleaning and production processes
Multifunctional applications
It is universal in multiple fields such as detergents, ceramics, water treatment, and petroleum Cost reduction and efficiency improvement
Reducing the amount of auxiliary materials can lower the overall cost by 15% to 20%
Environmental compliance
Complies with national standards and industrial emission requirements, ensuring safety and peace of mind
