Description

Calcium Didodecyl Bisphosphonate is a high-purity organophosphorus compound widely utilized as a highly effective scale and corrosion inhibitor. Its unique molecular structure provides superior performance in demanding aqueous systems, offering long-term stability and compatibility. This product is essential for industrial water treatment, oilfield production, and detergent formulations where controlling mineral scale and protecting metal surfaces are critical.

Application

• Industrial Water Treatment: Primary application as a threshold scale inhibitor for calcium carbonate, calcium sulfate, and barium sulfate in cooling towers, boilers, and reverse osmosis systems.
• Oilfield Chemicals: Key component in squeeze treatments and production chemicals to prevent scale deposition in downhole and topside equipment, enhancing production efficiency.
• Detergent & Cleaning Formulations: Acts as a builder and sequestrant to inactivate water hardness ions, improving surfactant performance and preventing scale on appliances and surfaces.
• Pulp & Paper Processing: Used to control scale formation in digesters, washers, and bleach plants, maintaining heat transfer efficiency and equipment longevity.
• Textile Processing: Prevents scale buildup in dyeing baths and finishing operations, ensuring consistent color quality and fabric handling.
• Personal Care Products: Incorporated in select formulations for its chelating properties to stabilize product integrity against hard water.

Quality Control

Our Calcium Didodecyl Bisphosphonate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure consistent purity, performance, and compliance with industry specifications. Certificates of Analysis (COA) documenting key parameters such as active content, calcium content, and impurity levels are provided and available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from strong oxidizing agents. The product is hygroscopic (moisture-sensitive); ensure the container is resealed tightly after each use to prevent moisture absorption and caking.
