Description

4-[[2-[(Carboxymethyl)[2-[(Carboxymethyl)Dodecylamino]Ethyl]Amino]Ethyl]Amino]-4-Oxo-2-Sulfobutanoic Acid Tetrasodium Salt is a high-purity, water-soluble chelating agent and surfactant, primarily recognized for its exceptional metal ion sequestration capabilities. This compound is engineered to deliver superior performance in demanding industrial processes where control of metal ions is critical for product stability and process efficiency. It is an essential raw material for formulators and manufacturers in the detergent, personal care, textile processing, and water treatment industries.

Application

• Detergent & Cleaner Formulations: Acts as a powerful builder and chelant to inactivate water hardness ions (Ca²⁺, Mg²⁺), enhancing surfactant efficacy and preventing scale deposition.
• Personal Care Products: Used in shampoos, liquid soaps, and skin cleansers as a gentle yet effective chelating agent to stabilize formulations and improve foam quality.
• Textile Processing: Serves as a key component in scouring, bleaching, and dyeing baths to sequester metal ions that can cause fabric damage or uneven dyeing.
• Industrial & Institutional (I&I) Cleaning: Employed in hard surface cleaners, dishwashing formulations, and laundry detergents for commercial applications.
• Water Treatment: Functions as a scale and corrosion inhibitor in cooling water and boiler water systems by binding scale-forming cations.
• Pulp & Paper Manufacturing: Used in bleaching processes to chelate transition metals that catalyze the degradation of cellulose, improving pulp brightness and strength.
• Agriculture & Horticulture: Can be utilized in fertilizer and pesticide formulations to improve nutrient availability and stability by chelating micronutrients.
