Description

Ethanol, 2,2′-Iminobis-, Compd. With α-Phosphono-ω-(Tridecyloxy)Poly(Oxy-1,2-Ethanediyl) (Average Eo 3-12 Mol) is a specialized organophosphorus compound that functions as a highly effective surfactant and chelating agent. Its unique molecular structure, combining a phosphonic acid head with a polyethoxylated tail, provides exceptional performance in demanding industrial processes where metal ion control and surface activity are critical. This chemical is essential for manufacturers in sectors such as water treatment, textile processing, and industrial cleaning, where it delivers superior scale inhibition, dispersion, and detergency.

Application

• Industrial Water Treatment: Acts as a powerful scale and corrosion inhibitor in cooling towers, boilers, and reverse osmosis systems, particularly effective against calcium carbonate and sulfate scales.
• Textile Processing: Used as a dispersing and chelating agent in scouring, bleaching, and dyeing baths to sequester metal ions that can cause fabric discoloration and improve process uniformity.
• Industrial & Institutional (I&I) Cleaning: Serves as a key component in heavy-duty alkaline and acid cleaners for food processing, dairy, and transportation industries, enhancing soil removal and rinseability.
• Pulp & Paper Manufacturing: Functions as a dispersant and chelant in pulp bleaching stages (e.g., hydrogen peroxide bleaching) to improve brightness and protect equipment from scale.
• Metal Surface Treatment: Employed in metal cleaning, phosphating, and electroplating formulations to control water hardness and improve coating quality.
• Oilfield Chemicals: Utilized in scale inhibitor formulations for squeeze treatments and in drilling muds to control divalent cations.
• Personal Care & Cosmetics: Can be used as a chelating agent in shampoos, soaps, and other formulations to stabilize products and improve efficacy.
• Agriculture: Incorporated into certain pesticide and fertilizer formulations as a stabilizer and compatibility agent.
