Description

Polyoxy(Methyl-1,2-Ethanediyl), .Alpha.-Sulfo-.Omega.-(Dodecyloxy)-, Sodium Salt is a high-performance anionic-nonionic surfactant belonging to the alkyl ether sulfate class. This compound is valued for its excellent wetting, emulsifying, and foaming properties, even in challenging water conditions. It is a critical raw material for formulators in the personal care, industrial cleaning, and textile processing industries seeking stable and effective surfactant systems. The product is supplied under stringent quality control to ensure batch-to-batch consistency for demanding B2B applications.

Application

• Personal Care & Cosmetics: Primary surfactant in shampoos, body washes, and facial cleansers for rich, stable lather and mildness.
• Industrial & Institutional (I&I) Cleaners: Key component in heavy-duty degreasers, floor cleaners, and dishwashing liquids for superior grease cutting and wetting.
• Textile Processing: Used as a wetting agent, scouring aid, and emulsifier in dyeing and finishing baths to ensure even dye penetration and oil removal.
• Emulsion Polymerization: Acts as an effective emulsifier and stabilizer in the production of acrylic, vinyl acetate, and styrene-butadiene latexes.
• Agricultural Formulations: Employed as a wetting and spreading agent in pesticide and herbicide concentrates to enhance foliar coverage and efficacy.
• Household Detergents: Found in liquid laundry detergents and all-purpose cleaners for its compatibility with other surfactants and hard water tolerance.

Quality Control

Our Polyoxy(Methyl-1,2-Ethanediyl), .Alpha.-Sulfo-.Omega.-(Dodecyloxy)-, Sodium Salt is manufactured under a cGMP-compliant quality management system (ISO 9001). Each batch undergoes rigorous analytical testing, including assay (active matter), unsulfated matter, sulfate content, pH, and color, to ensure it meets stringent industry and customer-specific specifications. Comprehensive Certificates of Analysis (COA) documenting purity, physical properties, and safety data are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at ambient temperature (15-25°C/59-77°F). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product performance. Keep away from strong oxidizing agents.
