Tetrapotassium etidronate
What is Tetrapotassium etidronate?
Tetrapotassium etidronate (CAS 67953-76-8) is the fully neutralized potassium salt of etidronic acid, an alkaline solution for industrial and personal care applications.
Where is Tetrapotassium etidronate used?
- Personal care: stabilizes hydrogen peroxide-based hair colorants and bleaching creams by binding trace metals that catalyze decomposition
- Water treatment and industrial cleaning: prevents scale formation and protects metal surfaces from corrosion in alkaline conditions
- Textile and leather processing: controls hardness ions during dyeing and finishing
- Oilfield chemistry: incorporated into scale inhibitor packages to protect pipelines and downhole equipment from mineral deposit buildup
- It functions as a chelating agent and corrosion inhibitor, sequestering calcium, magnesium, and heavy metal ions.
Commercial specifications
- Aqueous solution, 35–40% active content
- Bulk supply in IBC containers and drums
