Description

Dimethylbis[2-[(1-Oxohexadecyl)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-based chelating agent. This combination makes it particularly effective in formulations requiring both surface activity and scale inhibition or metal ion control. It is a critical ingredient for manufacturers in the personal care, industrial cleaning, and water treatment sectors seeking advanced performance in complex formulations.

Application

• Hair Conditioners & Cream Rinses: Acts as a primary cationic surfactant, providing excellent detangling, softness, and manageability to hair.
• Fabric Softeners: Imparts a soft, smooth feel to textiles while offering anti-static properties.
• Industrial & Institutional (I&I) Cleaners: Used in acid-based and alkaline cleaning formulations for hard surface cleaning, where it provides wetting, emulsification, and scale prevention.
• Water Treatment Formulations: Functions as a corrosion and scale inhibitor in cooling water systems and boiler water treatments due to its phosphonate group.
• Personal Care Cleansers: Incorporated into skin cleansers and shampoos for its mildness and conditioning benefits.
• Agricultural Adjuvants: Enhances the spreading and adhesion of pesticides and herbicides on plant surfaces.
• Metalworking Fluids: Serves as a lubricity agent and corrosion inhibitor in synthetic and semi-synthetic metalworking fluids.

Quality Control

Our Dimethylbis[2-[(1-Oxohexadecyl)Oxy]Ethyl]Ammonium Methyl Phosphonate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including assay, identification, and impurity profiling, to ensure it meets precise specifications for performance and consistency. Certificates of Analysis (COA) documenting purity, physical characteristics, and compliance are available upon request for every shipment.

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 affect product quality and performance.
