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, even in hard water and across a wide pH range. It is a critical ingredient for formulators in the personal care, home care, and industrial cleaning sectors seeking effective, biodegradable, and mild alternatives.

Application

• Personal Care Formulations: Primary surfactant in liquid hand soaps, body washes, shampoos, and facial cleansers for its rich lather and mildness.
• Household & Institutional Cleaners: Key component in dishwashing liquids, all-purpose cleaners, and hard surface cleaners due to its superior detergency and foam stability.
• Industrial & Mechanical Applications: Used in car wash formulations, textile processing aids, and as an emulsifier in agricultural products.
• Enhanced Oil Recovery (EOR): Employed in chemical flooding processes to reduce interfacial tension and improve oil displacement.
• Fire-Fighting Foams: Utilized in some aqueous film-forming foam (AFFF) concentrates for its rapid foam generation and spreading characteristics.

Quality Control

Our Sodium α-Olefin Sulfonate is manufactured under a strict quality management system. Each batch is analyzed to ensure it meets precise specifications for active matter content, unsulfated matter, sodium sulfate, and pH. Certificates of Analysis (COA) are provided with every shipment to guarantee consistency, purity, and performance for your formulations.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive). Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep container tightly sealed when not in use to prevent caking or absorption of moisture.
