Properties

Potassium Tripolyphosphate (KTPP) is a hygroscopic white material, granular, soluble in water, which gives moderately alkaline solutions. Potassium Tripolyphosphate is sequestering agent (excellent sequestrant of calcium, magnesium and iron in food products). Potassium Tripolyphosphate is highly soluble in aqueous solutions with excellent dispersion properties. Potassium Tripolyphosphate is easy to dissolve in water with solubility of 178g, 194g, and 212g in 100 mL of water at 10°C, 25°C, and 50°C respectively.
Potassium Tripolyphosphate has excellent chelating ability and can form stable chelates with Ca2+ and Mg2+ in hard water so as to soften hard water, increase cleaning ability, and remove dirt. The white precipitate formed from adding 13mL of 1% calcium nitrate solution into 100 mL of 1% potassium pyrophosphate solution can be rapidly chelated to produce a clear solution. 

Applications

Potassium Tripolyphosphate can form a protective film on the surface of iron, lead, zine, and other metals so as to prevent surface corroding. P2O74- has a strong dispersion ability to disperse finely distributed solid particles so that these fine and trace materials can mix evenly. Potassium Tripolyphosphate has stable pH buffering ability and keep solution pH value unchanged for a long time. Potassium Tripolyphosphate is used as a builder for soaps, detergents and especially liquid cleaning formulations.
