Description

Tetrasodium Dodecane-1,1,12,12-Tetracarboxylate is a high-purity, water-soluble chelating agent and surfactant derived from a long-chain dicarboxylic acid. This compound matters for its exceptional ability to sequester and deactivate di- and trivalent metal ions, such as calcium and magnesium, in aqueous systems. Industrial manufacturers and formulators need it for creating high-performance cleaning products, water treatment chemicals, and textile processing aids where control of water hardness and metal ion interference is critical.

Application

• Industrial & Institutional (I&I) Cleaners: As a key builder and chelant in heavy-duty alkaline cleaners, degreasers, and detergent formulations to prevent scale formation and improve surfactant efficacy.
• Textile Processing: Used in scouring, bleaching, and dyeing baths to sequester metal ions that can cause fabric damage, uneven dyeing, or catalytic decomposition of bleaching agents.
• Water Treatment: Acts as a scale and corrosion inhibitor in boiler water, cooling water, and reverse osmosis systems by binding hardness ions.
• Personal Care & Cosmetics: Employed as a chelating agent in shampoos, liquid soaps, and other rinse-off products to enhance stability and performance of other ingredients.
• Pulp & Paper Industry: Utilized in bleaching processes to protect cellulose fibers from metal-catalyzed degradation, improving pulp brightness and strength.
• Metal Surface Treatment: Functions in metal cleaning, plating, and phosphating solutions to control water hardness and prevent precipitation on metal surfaces.

Quality Control

Our Tetrasodium Dodecane-1,1,12,12-Tetracarboxylate is manufactured under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure consistent purity and performance, meeting the specifications required for industrial and specialty chemical applications. Certificates of Analysis (COA) documenting key parameters are available upon request.

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 lead to caking or reduced flowability.
