Description

10,10-Dihydroxy-3,6-Bis[2-(Phosphonooxy)Ethyl]-9-Oxa-3,6-Diaza-10-Phosphadecyl Dihydrogen Phosphate 10-Oxide, Sodium Salt is a complex organophosphorus compound with multiple phosphate and phosphonate groups, offered as a sodium salt for enhanced solubility and handling. This structure is engineered to provide exceptional chelating and sequestering power, making it a critical performance additive in applications requiring control over metal ions and scale formation. It is primarily sought by formulators in the water treatment, detergent, and industrial cleaning sectors for its superior multi-functional capabilities.

Application

• Industrial Water Treatment: Acts as a high-performance scale and corrosion inhibitor in cooling water systems, boilers, and reverse osmosis membranes.
• Detergent & Cleaning Formulations: Serves as a powerful builder and sequestrant to enhance cleaning efficiency by inactivating water hardness ions (Ca²⁺, Mg²⁺).
• Pulp & Paper Processing: Used as a chelating agent in bleaching processes to stabilize peroxides and improve brightness.
• Textile Auxiliary: Functions as a dispersant and sequestrant in dyeing and finishing baths to prevent metal-ion interference.
• Oilfield Chemicals: Employed in scale inhibition for production wells and pipelines to maintain flow assurance.
• Metal Surface Treatment: Used in metal cleaning and plating baths to control water hardness and prevent precipitation.
• Personal Care Products: May be utilized in specific formulations as a stabilizing agent for sensitive ingredients.

Quality Control

Our production of this specialty phosphonate adheres to strict quality management systems. Every batch is analyzed to ensure consistent performance and meets the specifications required for industrial applications. Certificates of Analysis (COA) detailing key parameters such as active content, pH, and density are provided with each shipment. We support our global clients with documentation to aid in their own regulatory and compliance efforts.

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). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which may lead to caking or reduced efficacy.
