Description

[Nitrilotris(Methylene)]Tris-Phosphonic Acid Pentasodium Salt is a highly effective phosphonate-based scale and corrosion inhibitor, valued for its exceptional chelating power and thermal stability in aqueous systems. Its primary commercial value lies in its ability to prevent the precipitation of calcium, magnesium, and other metal ions under demanding conditions, ensuring operational efficiency and protecting capital equipment. This product is essential for industrial water treatment, detergent formulation, and as a key additive in oilfield and textile processing applications.

Application

• Industrial Water Treatment: Primary application as a scale inhibitor and dispersant in cooling towers, boilers, and reverse osmosis systems to control calcium carbonate, sulfate, and phosphate scales.
• Detergent & Cleaning Formulations: Acts as a builder and sequestrant to enhance cleaning efficiency by inactivating water hardness ions and preventing soil redeposition.
• Oilfield Chemicals: Used in drilling fluids, production chemicals, and squeeze treatments to control scale formation in downhole and topside equipment.
• Textile Processing: Serves as a peroxide stabilizer and sequestrant in bleaching baths to improve process efficiency and fabric quality.
• Pulp & Paper Industry: Employed as a chelant in bleaching sequences and as a dispersant to control pitch and deposits.
• Personal Care Products: Functions as a chelating agent in formulations such as shampoos and liquid soaps to improve stability and performance.

Quality Control

Our [Nitrilotris(Methylene)]Tris-Phosphonic Acid Pentasodium Salt is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for active content, pH, and impurity profiles. A comprehensive Certificate of Analysis (COA) detailing assay, identity, and physical parameters is provided with every shipment to guarantee traceability and compliance with your quality 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 material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which may lead to caking or reduced efficacy.
