Hydroxyethylethylenediaminetriacetic acid

Hydroxyethylethylenediaminetriacetic acid (CAS 150-39-0), commonly known as HEDTA, is a chelating agent used in industrial and personal care applications.

Where is Hydroxyethylethylenediaminetriacetic acid used?

• Personal care: deactivates trace metal ions that degrade active ingredients, preventing discoloration
• Water treatment: controls scale formation and metal ion interference in process water and cooling systems
• Textile and paper processing: sequesters hardness ions during bleaching and dyeing
• Cleaning formulations: keeps calcium and magnesium ions from reducing surfactant efficiency
• It binds and sequesters metal ions, particularly calcium, magnesium, iron, and heavy metals.

Good to know: Technical grade is the standard offering for industrial applications including water treatment; personal care applications may require grades meeting cosmetic or purity specifications aligned with industry standards.
