Description

Decaammonium [[Bis[2-[Bis(Phosphonatomethyl)Amino]Ethyl]Amino]Methyl]Phosphonate is a highly functionalized, multi-dentate phosphonate compound known for its exceptional chelating and scale inhibition properties. This advanced molecule is engineered to deliver superior performance in complex aqueous systems where control of metal ions and mineral deposits is critical. It is primarily utilized by industrial water treatment, oilfield chemical, and detergent formulation sectors seeking high-efficacy, multi-functional additives.

Application

• Industrial Water Treatment: Acts as a powerful scale and corrosion inhibitor in cooling towers, boilers, and reverse osmosis systems, particularly effective against calcium carbonate, sulfate, and phosphate scales.
• Oilfield Chemicals: Used in squeeze treatments and as a component in drilling and completion fluids to prevent mineral scale deposition in downhole equipment and formations.
• Detergent & Cleaning Formulations: Serves as a high-performance builder and sequestrant, enhancing cleaning power by inactivating water hardness ions (Ca²⁺, Mg²⁺) and providing anti-redeposition benefits.
• Pulp & Paper Processing: Functions as a chelant and dispersant to control metal-ion catalyzed decomposition of bleaching agents and to inhibit scale in digesters and washers.
• Textile Processing: Used in bleaching, dyeing, and finishing baths to sequester metal ions that can cause fabric discoloration or degrade process chemicals.
• Personal Care Products: Incorporated into formulations as a stabilizing agent for peroxides and other active ingredients sensitive to metal ion contamination.

Quality Control

Our Decaammonium DTPMP is manufactured under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure consistent performance and purity. Certificates of Analysis (COA) documenting key parameters such as active content, pH, density, and phosphonate concentration are provided with every shipment. We adhere to relevant industry guidelines to support applications in water treatment and industrial formulations.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material 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.
