Description

Poly(Oxy-1,2-Ethanediyl), .Alpha.-(3-Carboxy-1-Oxosulfopropyl)-.Omega.-(Decyloxy)-, Disodium Salt is a high-performance, anionic surfactant and dispersant engineered for demanding industrial applications. Its unique molecular structure, featuring a decyl hydrophobic tail and a hydrophilic sulfocarboxylate head group linked by a polyoxyethylene spacer, provides exceptional wetting, emulsification, and calcium ion tolerance. This compound is essential for formulators seeking to enhance the stability and performance of aqueous systems. Key industries that rely on this specialty chemical include agrochemicals, coatings, textiles, and industrial cleaning.

Application

• Agrochemical Formulations: Acts as a superior wetting agent, dispersant, and emulsifier in suspension concentrates (SC) and wettable powders (WP) for pesticides and herbicides.
• Industrial & Institutional (I&I) Cleaners: Provides powerful detergency and soil suspension in heavy-duty alkaline and acidic cleaning formulations for hard surface cleaning.
• Coatings & Paints: Used as a pigment grinding aid and dispersant in water-based architectural and industrial coatings to improve color development and prevent settling.
• Textile Processing: Functions as a scouring agent, dye leveler, and dispersant in pretreatment and dyeing baths to ensure uniform results.
• Enhanced Oil Recovery (EOR): Investigated for use as a surfactant in chemical flooding applications due to its interfacial tension reduction properties.
• Construction Chemicals: Employed as a plasticizer and water-reducing agent in cement admixtures to improve workability.
• Personal Care: Can be used as a mild surfactant and foam booster in select rinse-off products, subject to appropriate grade and certification.
• Metal Working Fluids: Serves as an emulsifier and corrosion inhibitor in synthetic and semi-synthetic metalworking coolants.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed when not in use to prevent absorption of atmospheric moisture, which can lead to caking or performance variation. Keep away from strong oxidizing agents.
