Description

Disodium Hydrogen Phosphonatoacetate is a high-purity, water-soluble organophosphonate salt with excellent chelating and scale inhibition properties. Its unique molecular structure makes it a highly effective and stable sequestrant for metal ions, particularly calcium and magnesium, under demanding conditions. This compound is essential for formulators and manufacturers in the water treatment, detergent, and personal care industries seeking superior performance in preventing scale and stabilizing active ingredients.

Application

• Industrial Water Treatment: A key component in cooling water and boiler water treatment formulations for scale and corrosion inhibition.
• Detergent & Cleaning Agents: Functions as a powerful builder and chelating agent in liquid and powder detergents, enhancing cleaning efficiency by inactivating water hardness ions.
• Personal Care Products: Used in shampoos, liquid soaps, and other cosmetic formulations as a stabilizer and sequestrant to improve product clarity and shelf life.
• Pulp & Paper Processing: Acts as a chelant and dispersant in bleaching and pulping processes to improve efficiency and protect equipment.
• Textile Auxiliaries: Employed in dyeing and finishing baths to sequester metal ions that can interfere with dye uptake and fabric quality.
• Oilfield Chemicals: Utilized in scale inhibitor formulations for downhole and topside applications to prevent mineral scale deposition.

Quality Control

Our Disodium Hydrogen Phosphonatoacetate is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, identity, and performance. Certificates of Analysis (COA) documenting key parameters are provided with each shipment and are available upon request.

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 can lead to caking or reduced efficacy.
