Description

Sodium α-Olefin Sulfonate (AOS) is a high-performance anionic surfactant derived from linear α-olefins. This compound is valued for its excellent foaming, wetting, and emulsifying properties, along with its high stability across a wide pH range and good compatibility with hard water. It is a critical ingredient for formulators seeking effective, biodegradable, and cost-efficient cleaning and foaming agents. Key industries that utilize this surfactant include personal care, household & industrial cleaning, textile processing, and enhanced oil recovery.

Application

• Personal Care Products: Primary surfactant in liquid hand soaps, body washes, shampoos, and shaving creams due to its rich, stable lather and mildness on the skin.
• Household & Industrial Cleaners: Core component in dishwashing liquids, laundry detergents, all-purpose cleaners, and hard surface cleaners for its superior detergency and foam stability.
• Textile & Leather Processing: Used as a wetting agent, emulsifier, and scouring agent in textile manufacturing and leather treatment baths.
• Enhanced Oil Recovery (EOR): Employed as a chemical flooding agent to reduce interfacial tension and mobilize residual oil in reservoirs.
• Agricultural Adjuvants: Functions as a wetting and spreading agent in pesticide and herbicide formulations to improve coverage and efficacy.
• Industrial Emulsification: Serves as an emulsifier in the production of polymer emulsions, paints, and coatings.

Quality Control

Our Sodium α-Olefin Sulfonate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistency and compliance with relevant industry standards. Key parameters such as active matter content, unsulfated matter, sodium sulfate content, and pH are strictly controlled. A Certificate of Analysis (COA) documenting these results is available for every shipment upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from strong oxidizing agents. For long-term storage, ensure the container is kept sealed to prevent moisture absorption.
