Product Description

Sodium tripolyphosphate

Product information:
The appearance of sodium tripolyphosphate is white granular or powdery, which is gradually hydrolyzed into phosphite in water, and has good metal complexing ability. It can react with calcium, magnesium, iron and other metal ions to form soluble complexes. It can soften hard water. As an inorganic surfactant, it has certain properties of organic surfactant
