Tetrapotassium etidronate
Description
Tetrapotassium etidronate (CAS 67953-76-8) is the fully neutralized potassium salt of etidronic acid, supplied as a ready-to-use alkaline solution for industrial and personal care applications.
It functions as a chelating agent and corrosion inhibitor, sequestering calcium, magnesium, and heavy metal ions that would otherwise interfere with formulation stability or process efficiency.
In personal care formulations, it stabilizes hydrogen peroxide-based products such as hair colorants and bleaching creams by binding trace metals that catalyze decomposition.
Water treatment and industrial cleaning operations use it to prevent scale formation and protect metal surfaces from corrosion in alkaline process conditions.
Textile and leather processing facilities apply it to control hardness ions during dyeing and finishing, improving dye uptake consistency across various production batches.
In oilfield chemistry, it is incorporated into scale inhibitor packages to protect pipelines and downhole equipment from mineral deposit buildup in harsh environments.
Tetrapotassium etidronate is commercially available primarily as an aqueous solution, with 35–40% active content being the most commonly traded concentration range.
It is supplied in technical and cosmetic-grade specifications to meet the requirements of industrial buyers. Bulk supply is standard in IBC containers and drums.
