Description

Diethylenetriaminepenta(Methylenephosphonicacid) Sodium Salt is a high-performance, water-soluble phosphonate scale and corrosion inhibitor. This powerful chelating agent is valued for its exceptional stability across a wide pH and temperature range, making it a critical component in demanding industrial water treatment formulations. It is primarily utilized by professionals in the water treatment, oilfield, and detergent industries to prevent mineral scale deposition and control metal ion-induced oxidation.

Application

• Industrial Water Treatment: As a highly effective threshold inhibitor for calcium carbonate, calcium sulfate, and barium sulfate scale in cooling water, boiler water, and reverse osmosis systems.
• Oilfield Chemistry: Used in squeeze treatments and as an additive in drilling and completion fluids to control scale formation in downhole and production equipment.
• Detergent & Cleaning Formulations: Acts as a builder and sequestrant to inactivate water hardness ions (calcium, magnesium) and enhance cleaning efficiency in industrial and institutional cleaners.
• Pulp & Paper Processing: Employed as a chelant in bleaching processes to stabilize peroxides and control metal ions that catalyze decomposition.
• Textile Processing: Used to sequester metal ions in dyeing and bleaching baths, preventing shade variation and fabric damage.
• Personal Care Products: Functions as a chelating agent in formulations to improve stability and shelf-life by binding trace metals.

Quality Control

Our Diethylenetriaminepenta(Methylenephosphonicacid) Sodium Salt is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure consistent performance and meets relevant industry specifications for water treatment chemicals. Certificates of Analysis (COA) documenting key parameters such as active content, pH, and density are available upon request to support your quality assurance protocols.

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 handling properties.
