A polyphosphate sequestrant that softens water and disperses minerals without precipitate formation. Used in water treatment as a sequestrant and scale/corrosion inhibitor, in detergents, as a dispersant for clays and pigments, as a food additive (sequestrant and emulsifying salt), and as a thinner for drilling fluids.
▸Water treatment: Sequestrant and threshold scale/corrosion inhibitor
▸Detergents: Water softener and builder
▸Industrial dispersant: Deflocculant for clays and pigments
▸Food processing: Sequestrant and emulsifying salt
▸Drilling fluids: Viscosity thinner
