Description

Dodecylamine-N,n-Bis(Methylenephosphonic Acid) Sodium Salt is a high-performance organophosphonate compound, valued for its excellent chelating and scale inhibition properties. This amphiphilic molecule combines a long hydrophobic alkyl chain with hydrophilic phosphonate groups, making it a versatile functional additive. It is primarily used in industrial water treatment, oilfield chemicals, and as a corrosion inhibitor in various process industries where control of metal ions and mineral scale is critical.

Application

• Industrial Water Treatment: Acts as a highly effective scale and corrosion inhibitor in cooling water, boiler water, and reverse osmosis systems.
• Oilfield Chemicals: Used in drilling fluids, production chemicals, and squeeze treatments for scale control and as a corrosion inhibitor in downhole and pipeline applications.
• Detergent & Cleaning Formulations: Serves as a builder and chelating agent in industrial and institutional cleaning products to sequester hardness ions.
• Pulp & Paper Industry: Functions as a chelant and dispersant in bleaching processes and papermaking to control metal ions.
• Textile Processing: Used as a stabilizer and sequestrant in peroxide bleaching baths and other wet processing stages.
• Personal Care: May be utilized in specific formulations as a chelating agent and stabilizer.

Quality Control

Our production of Dodecylamine-N,n-Bis(Methylenephosphonic Acid) Sodium Salt adheres to stringent quality management protocols. Each batch undergoes comprehensive analytical testing to ensure consistent purity, performance, and compliance with relevant industry standards. Certificates of Analysis (COA) documenting key parameters such as assay, active content, pH, and moisture are available upon request to support your quality assurance processes.

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); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which may lead to caking or reduced efficacy.
