Description

n-Dodecyl-B-Iminodipropionic Acid, Disodium Salt is a high-purity, amphoteric surfactant and chelating agent derived from iminodipropionic acid. This compound is valued for its excellent metal ion sequestration, surface activity, and compatibility across a wide pH range, making it a versatile functional additive. It is essential for formulators and manufacturers in the personal care, industrial cleaning, and textile processing industries seeking effective, mild, and stable performance.

Application

• Personal Care Formulations: Used as a mild surfactant and chelating agent in shampoos, body washes, and facial cleansers to enhance foam stability and sequester water hardness ions.
• Industrial & Institutional (I&I) Cleaners: Acts as a key component in alkaline and acidic cleaning formulations for hard surface cleaners and metal treatment baths, where it controls metal ions and improves surfactant performance.
• Textile Auxiliaries: Employed in dyeing and finishing processes as a leveling agent and chelant to prevent metal-ion interference, ensuring consistent color and fabric quality.
• Agricultural Chemicals: Serves as a stabilizer and compatibility agent in pesticide and herbicide formulations, improving efficacy and shelf life.
• Oilfield Chemicals: Functions as a scale inhibitor and surfactant in drilling and production fluids to control mineral deposition and improve fluid performance.
• Plating & Metalworking Fluids: Utilized as a chelating agent in electroplating baths and metalworking fluids to complex interfering metal ions and maintain solution stability.
