Description

Phosphonic Acid, (1-Hydroxyethylidiene)Bis-, Mixt. With Pentasodium Hydrogen [Nitrilotris(Methylene)]Tris[Phosphonate] is a high-performance, synergistic blend of two potent phosphonate-based scale and corrosion inhibitors. This formulation is engineered to deliver superior sequestration and dispersion of metal ions, particularly calcium, magnesium, and iron, under demanding conditions. It is a critical component for industrial water treatment, oilfield applications, and detergent formulations where scale control and metal ion stabilization are paramount for operational efficiency and equipment longevity.

Application

• Industrial Water Treatment: Primary scale and corrosion inhibitor in cooling towers, boilers, reverse osmosis (RO) systems, and desalination plants.
• Oilfield Chemicals: Used in squeeze treatments and as an additive in drilling and completion fluids to prevent carbonate and sulfate scale deposition in downhole equipment and pipelines.
• Detergent & Cleaning Formulations: Acts as a builder and sequestrant to inactivate water hardness ions, enhancing the cleaning efficiency of laundry detergents, industrial cleaners, and automatic dishwashing products.
• Pulp & Paper Processing: Prevents scale formation on digesters, evaporators, and paper machines, and aids in peroxide stabilization during bleaching stages.
• Textile Processing: Used as a chelating agent in dyeing and bleaching baths to prevent metal-ion interference and improve color fastness.
• Personal Care Products: Functions as a chelating agent in shampoos, liquid soaps, and other formulations to improve stability and clarity.
