【 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.
