Description

Disodium [Ethylenebis(Oxyethyleneoxy)]Bispropanesulphonate is a high-purity, water-soluble anionic surfactant and complexing agent. This compound is valued for its excellent chelating power, surface activity, and stability across a wide pH range, making it a critical performance additive. It is primarily needed by manufacturers in the personal care, textile processing, industrial cleaning, and water treatment industries to enhance formulation efficacy and process control.

Application

• Personal Care & Cosmetics: Acts as a gentle yet effective surfactant and emulsifier in shampoos, body washes, and facial cleansers.
• Textile Auxiliary: Used as a leveling agent, dispersant, and chelating agent in dyeing and printing processes to improve color uniformity.
• Industrial & Institutional (I&I) Cleaning: Serves as a key component in hard surface cleaners, degreasers, and detergent formulations for its soil suspension and sequestration properties.
• Water Treatment: Functions as a scale and corrosion inhibitor in cooling water and boiler water systems by chelating calcium and magnesium ions.
• Paints & Coatings: Employed as a dispersant and stabilizer for pigments and fillers in aqueous coating systems.
• Agriculture: Used in pesticide and herbicide formulations to improve wetting, spreading, and system stability.
• Metal Surface Treatment: Acts as a complexing agent in electroplating and metal cleaning baths to control metal ion concentration.
• Polymerization: Can be utilized as an emulsifier or stabilizer in emulsion polymerization processes.
