Description

Tetrasodium [(Heptylimino)Bis(Methylene)]Bisphosphonate is a high-performance organophosphonate compound widely used as a scale and corrosion inhibitor. Its unique molecular structure provides excellent chelating and threshold inhibition properties, making it effective in controlling mineral scales even at low dosages. This chemical is essential for industrial water treatment, oilfield applications, and detergent formulations where stability under harsh conditions is required.

Application

• Industrial Water Treatment: Primary application as a scale inhibitor for calcium carbonate, calcium sulfate, and barium sulfate in cooling towers, boilers, and reverse osmosis systems.
• Oilfield Chemicals: Used in squeeze treatments and as an additive in drilling and completion fluids to prevent scale deposition in downhole equipment and formations.
• Detergent & Cleaning Formulations: Acts as a builder and chelating agent to sequester hardness ions (Ca²⁺, Mg²⁺), enhancing the cleaning efficiency of soaps and detergents.
• Pulp & Paper Industry: Employed in process water systems to control scale and disperse pitch, improving operational efficiency and product quality.
• Textile Processing: Used in dyeing and bleaching baths to prevent metal-ion catalyzed decomposition of bleaching agents and to inhibit scale on machinery.
• Personal Care Products: Incorporated as a stabilizing and chelating agent in certain cosmetic and personal care formulations.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which may lead to caking or reduced efficacy. Keep away from strong oxidizing agents.
