Trade Name: ValuQuest 6000
CAS #: 2809-21-4
HEDP (1-hydroxyethylidene 1,1-diphosphonic acid) is a phosphonate chelating agent used across industrial and formulation applications. It is commonly employed as a corrosion inhibitor in metal treatment and water-contact systems, where it binds metal ions to slow oxidative damage. Additionally, it serves as a general-purpose chelating agent that sequesters calcium, magnesium, and trace metal ions across a range of formulations. HEDP is also utilized as a textile auxiliary, assisting in scouring, bleaching, and dyeing processes where metal-ion control improves finishing consistency. Furthermore, it finds applications as a functional additive in washing and cleaning products, and as a general formulation additive in specialty chemical blends requiring phosphonate chemistry.
