Description

4-[[2-[[2-(Decylamino)Ethyl]Amino]Ethyl]Amino]-4-Oxo-2-Sulfobutanoic Acid Disodium Salt is a high-purity, water-soluble anionic surfactant and complexing agent derived from a modified aspartic acid structure. This compound is valued for its excellent chelating properties, particularly towards multivalent metal ions, and its ability to function as a mild surfactant in demanding formulations. It is primarily utilized in industrial cleaning, personal care, and water treatment applications where effective sequestration and surface activity are required.

Application

• Industrial & Institutional (I&I) Cleaners: Acts as a key chelating agent and co-surfactant in heavy-duty alkaline cleaners, degreasers, and detergent formulations to control water hardness and improve cleaning efficacy.
• Personal Care Products: Used in shampoos, body washes, and facial cleansers as a mild surfactant and conditioning agent that helps stabilize formulations and improve foam characteristics.
• Water Treatment Chemicals: Employed as a scale and corrosion inhibitor in cooling water systems and boiler water treatment by sequestering calcium, magnesium, and other metal ions.
• Textile & Leather Processing: Functions as a dispersing and chelating agent in dyeing baths and finishing processes to improve color fastness and product quality.
• Metal Surface Treatment: Serves as an additive in electroplating baths and metal cleaning solutions to complex impurities and enhance surface finish.
• Agricultural Formulations: Incorporated into pesticide and herbicide concentrates as a stabilizer and compatibility agent to improve tank-mix performance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the original container must be kept tightly sealed after use to prevent absorption of atmospheric moisture which may lead to caking or degradation.
