Description

Hdtmp Hexapotassium Salt CAS NO 38820-59-6 is the hexapotassium salt of 1-Hydroxyethane-1,1-diphosphonic acid (HEDP), a highly effective organic phosphonic acid compound. This specialized salt form offers superior solubility and handling characteristics, making it a critical performance additive in industrial water treatment and scale inhibition. It is primarily utilized by formulators and manufacturers in the water treatment, detergent, and textile processing industries who require a high-performance, stable, and soluble phosphonate source.

Application

• Industrial Water Treatment: Acts as a highly effective scale and corrosion inhibitor in cooling water systems, boiler water, and reverse osmosis (RO) membranes.
• Detergent & Cleaning Formulations: Serves as a superior builder and sequestrant to control water hardness, enhancing the cleaning efficiency of industrial and institutional detergents.
• Textile & Pulp Processing: Used as a stabilizer and chelating agent in peroxide bleaching baths and other chemical processes to improve efficiency and product quality.
• Oilfield Applications: Employed in scale control for oilfield injection water and as a stabilizer in drilling fluid formulations.
• Personal Care Products: Functions as a chelating agent in certain cosmetic and personal care formulations to enhance stability.
• Industrial Cleaning: Key component in metal cleaning and surface treatment formulations to prevent scale deposition and improve rinsability.

Quality Control

Our Hdtmp Hexapotassium Salt is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, potency, and performance. Certificates of Analysis (COA) documenting key parameters such as assay, pH, and impurity levels are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); ensure the original container is securely sealed after each use to prevent absorption of atmospheric moisture, which can lead to caking or reduced efficacy.
