Description

Sodium n-[Imino(Phosphonoamino)Methyl]-n-Methylaminoacetate is a specialized organophosphorus compound with a unique aminophosphonate structure. This chemical is valued for its excellent chelating and scale inhibition properties, particularly in aqueous systems where it controls the precipitation of metal ions. It is primarily required by industrial water treatment, detergent formulation, and textile processing sectors for its ability to enhance performance and prevent fouling.

Application

• Industrial Water Treatment: Acts as a highly effective scale and corrosion inhibitor in cooling towers, boilers, and reverse osmosis systems.
• Detergent & Cleaning Formulations: Serves as a powerful builder and sequestrant to enhance cleaning efficiency by inactivating water hardness ions (Ca²⁺, Mg²⁺).
• Textile Processing: Used in bleaching and dyeing baths to stabilize peroxides and prevent metal-ion catalyzed degradation of fabrics.
• Pulp & Paper Manufacturing: Functions as a chelant in bleaching processes to improve brightness and protect equipment from scale.
• Oilfield Chemicals: Employed in scale squeeze treatments and as an additive in drilling fluids to control mineral deposition.
• Personal Care Products: Incorporated as a stabilizing agent in formulations such as hydrogen peroxide-based hair colorants.
