Product Overview

Potassium Tripolyphosphate (KTPP) is an inorganic potassium phosphate compound with the chemical formula K₅P₃O₁₀. It appears as a white crystalline powder, highly soluble in water, and provides excellent chelating, dispersing, emulsifying, and buffering properties.

Compared with sodium tripolyphosphate (STPP), potassium tripolyphosphate contains no sodium, making it particularly suitable for low-sodium or sodium-free formulations in food and industrial applications.
