Description

4-[[2-[(Carboxymethyl)[2-[(Carboxymethyl)Decylamino]Ethyl]Amino]Ethyl]Amino]-4-Oxo-2-Sulfobutanoic Acid Tetrasodium Salt is a high-purity, water-soluble chelating agent and surfactant, designed for demanding industrial applications where effective metal ion sequestration and surface activity are critical. Its molecular structure, featuring multiple carboxylate and sulfonate groups, provides exceptional binding capacity for polyvalent metal cations, particularly calcium and magnesium, under a wide range of pH conditions. This compound is essential for formulators and manufacturers in sectors such as personal care, industrial cleaning, and textile processing, where it enhances product stability, performance, and efficiency.

Application

• Personal Care & Cosmetics: Acts as a highly effective chelating agent in shampoos, body washes, and creams to stabilize formulations by inactivating metal ions that can cause rancidity and degradation.
• Industrial & Institutional (I&I) Cleaning: Serves as a key builder and sequestrant in heavy-duty alkaline cleaners, degreasers, and detergent formulations, boosting cleaning power by controlling water hardness.
• Textile Processing: Used in scouring, bleaching, and dyeing baths to prevent metal-ion interference, ensuring uniform dye uptake, brighter colors, and improved fabric quality.
• Pulp & Paper Manufacturing: Functions as a stabilizer in hydrogen peroxide bleaching processes, deactivating catalytic metal ions that decompose the bleaching agent.
• Water Treatment: Employed as a scale inhibitor and dispersant in cooling water systems and boiler water treatment to prevent the deposition of calcium and magnesium salts.
• Agrochemical Formulations: Enhances the stability and efficacy of liquid fertilizers and pesticide concentrates by chelating micronutrients and preventing precipitate formation.

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 product is hygroscopic (moisture-sensitive); the original container must be kept tightly sealed after each use to prevent absorption of atmospheric moisture, which can lead to caking or reduced efficacy.
