Description

Tetrasodium [(Dodecylimino)Bis(Methylene)]Bisphosphonate is a high-performance organophosphonate compound valued for its exceptional chelating and scale inhibition properties. This chemical is a critical additive in formulations where control of metal ions and prevention of inorganic salt deposits is paramount. It is primarily utilized by industries such as industrial water treatment, detergent manufacturing, and oilfield production to enhance process efficiency and protect equipment.

Application

• Industrial Water Treatment: Acts as a highly effective scale and corrosion inhibitor in cooling towers, boilers, and reverse osmosis systems.
• Detergent & Cleaning Formulations: Functions as a powerful builder and sequestrant to improve cleaning efficacy by inactivating water hardness ions (Ca²⁺, Mg²⁺).
• Oilfield Chemicals: Used in drilling fluids, completion brines, and squeeze treatments to prevent carbonate and sulfate scale formation in downhole equipment.
• Pulp & Paper Processing: Serves as a chelant in bleaching processes and as a dispersant to control pitch and deposits.
• Textile Auxiliary: Employed as a stabilizer in peroxide bleaching baths and a sequestrant in dyeing processes to ensure color uniformity.
• Personal Care Products: Incorporated in certain formulations as a chelating agent to enhance stability and performance.

Quality Control

Our Tetrasodium [(Dodecylimino)Bis(Methylene)]Bisphosphonate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for active content, pH, and impurity profiles. Certificates of Analysis (COA) documenting purity, identity, and key physical-chemical parameters 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); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture and caking.
