Description

α-Sulfo-ω-(Octadecyloxy)Poly(Oxy-1,2-Ethanediyl), Sodium Salt is a high-performance anionic surfactant belonging to the class of alkyl ether sulfates. This compound is valued for its excellent wetting, emulsifying, and foaming properties, particularly in demanding formulations. It is a critical raw material for manufacturers in the personal care, industrial cleaning, and textile processing sectors who require reliable performance and consistent quality from their specialty chemicals.

Application

• Personal Care Formulations: Acts as a primary surfactant in shampoos, body washes, and liquid soaps, providing rich lather and mild cleansing.
• Industrial & Institutional (I&I) Cleaners: Used in heavy-duty degreasers, floor cleaners, and vehicle wash systems for its powerful emulsification of oils and greases.
• Textile Auxiliaries: Serves as a wetting agent, scouring aid, and emulsifier in fabric preparation and dyeing processes.
• Emulsion Polymerization: Functions as an effective emulsifier and stabilizer in the production of acrylic, vinyl acetate, and styrene-butadiene latexes.
• Agricultural Adjuvants: Incorporated into pesticide and herbicide formulations to enhance spreading and adhesion on plant surfaces.
• Leather Processing: Used in beamhouse operations for wetting and degreasing hides and skins.

Quality Control

Our production of α-Sulfo-ω-(Octadecyloxy)Poly(Oxy-1,2-Ethanediyl), Sodium Salt adheres to stringent quality management protocols. Every batch is analyzed to ensure consistency in active matter content, sulfate content, and critical physical parameters. Certificates of Analysis (COA) documenting purity, pH, and other key specifications are provided to guarantee the material meets your formulation requirements.

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 material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product performance.
