HEDP (Hydroxyethylidene Diphosphonic Acid)

HEDP (Hydroxyethylidene Diphosphonic Acid) is an organophosphonate compound with the chemical formula C₂H₈O₇P₂. It is a colorless liquid or crystalline powder that acts as a powerful chelating agent, capable of binding to metal ions and preventing scale formation and corrosion. HEDP is stable at high temperatures and in acidic environments, making it a valuable additive in water treatment and industrial cleaning.

Common uses of HEDP:

Water Treatment: Used to prevent scale and corrosion in industrial water systems. Detergents and Cleaning Products: As a chelating agent to enhance cleaning efficiency. Textile Industry: To prevent metal ion interference during dyeing and finishing processes. Cosmetics: In formulations to stabilize and prevent oxidation.
