Description

Trisodium Hydrogen [(Octylimino)Bis(Methylene)]Bisphosphonate is a high-performance organophosphonate compound widely recognized for its exceptional chelating and scale inhibition properties. Its primary value lies in its ability to effectively control scale formation and corrosion in aqueous systems, even at low dosages and under demanding conditions. This makes it a critical additive for industrial water treatment, oilfield operations, and detergent formulations where system efficiency and longevity are paramount.

Application

• Industrial Water Treatment: Primary application as a highly effective scale and corrosion inhibitor in cooling water systems, boilers, and reverse osmosis (RO) membranes.
• Oilfield Chemicals: Used in scale squeeze treatments and as an additive in drilling and completion fluids to prevent mineral scale deposition (e.g., calcium carbonate, barium sulfate) 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, detergents, and industrial cleaners.
• Pulp & Paper Industry: Employed in process water systems to control scale and as a peroxide stabilizer in bleaching stages to improve efficiency.
• Textile Processing: Used to prevent scale buildup on machinery and to improve dyeing processes by sequestering metal ions.
• Personal Care Products: Functions as a chelating agent in shampoos, liquid soaps, and other formulations to improve stability and shelf life.

Quality Control

Our production of Trisodium Hydrogen [(Octylimino)Bis(Methylene)]Bisphosphonate adheres to stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including assay by titration, identification by FT-IR, and measurement of key physical parameters like pH and active content. We provide full traceability and Certificates of Analysis (COA) are available for all shipments to ensure compliance with your specific application requirements.

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 original container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can lead to caking or reduced efficacy.
