Description

[Methanetetrayltetrakis(Methyleneoxy)]Tetraphosphonic Acid Octaammonium Salt is a high-performance organophosphonate compound, valued for its exceptional chelating and scale inhibition properties in aqueous systems. Its multi-phosphonic acid structure provides superior sequestration of di- and trivalent metal ions, preventing precipitation and fouling. This product is essential for industrial water treatment, detergent formulations, and as a processing aid in textile and paper manufacturing where control of water hardness is critical.

Application

• Industrial Water Treatment: Primary application as a highly effective scale and corrosion inhibitor in cooling towers, boilers, and reverse osmosis systems.
• Detergent & Cleaning Formulations: Acts as a powerful builder and sequestrant to enhance cleaning efficiency by inactivating water hardness ions (Ca²⁺, Mg²⁺).
• Textile Processing: Used as a peroxide stabilizer and sequestrant in bleaching and dyeing baths to prevent metal-ion catalyzed degradation of fabrics and dyes.
• Pulp & Paper Manufacturing: Employed to control scale formation and improve peroxide bleaching efficiency, protecting equipment and ensuring product brightness.
• Oilfield Applications: Functions as a scale inhibitor in squeeze treatments to prevent mineral scale deposition in wellbores and production equipment.
• Personal Care Products: Incorporated into formulations as a chelating agent to stabilize products and improve efficacy against hard water.

Quality Control

Our [Methanetetrayltetrakis(Methyleneoxy)]Tetraphosphonic Acid Octaammonium Salt is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent performance and purity. A comprehensive Certificate of Analysis (COA) detailing assay, active content, pH, and other critical parameters is provided with every shipment to guarantee compliance with your specifications.

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