Description

Dimethylbis[2-[(1-oxooctadecyl)oxy]ethyl]ammonium methyl phosphonate is a specialized quaternary ammonium phosphonate compound, valued for its unique dual functionality as a cationic surfactant and a phosphonate chelating agent. This combination makes it a highly effective ingredient for applications requiring both surface activity and scale inhibition. It is primarily sought by formulators in the industrial cleaning, personal care, and water treatment sectors for developing high-performance, multi-functional products.

Application

• As a key cationic surfactant and conditioning agent in hair conditioners, cream rinses, and fabric softeners.
• As a multi-functional additive in industrial and institutional cleaning formulations, providing emulsification and anti-scaling properties.
• As a corrosion and scale inhibitor in cooling water treatment and boiler water systems.
• As an emulsifier and dispersant in agrochemical formulations and pesticide emulsions.
• As a softening and antistatic agent in textile processing and finishing.
• In the synthesis of specialty quaternary ammonium compounds with enhanced bioactivity or material properties.

Quality Control

Our Dimethylbis[2-[(1-oxooctadecyl)oxy]ethyl]ammonium methyl phosphonate is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure identity, purity, and performance consistency. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and physical specifications is provided and available upon request to support your quality assurance protocols.

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 to prevent absorption of atmospheric moisture, which can affect product quality.
