What Is Alpha Olefin Sulfonate (AOS) 92%?

Alpha Olefin Sulfonate (AOS) is a high-activity anionic surfactant derived from linear alpha olefins, offering strong detergency, stable foam, and better mildness than many traditional sulfates.

It is a high-concentration grade (~92% active), usually in powder or paste form, designed for concentrated systems and flexible manufacturing.

AOS-92 delivers strong cleaning performance with lower dosage, helping reduce formulation cost, improve processing flexibility, and optimize storage and transportation efficiency.

It is highly compatible with co-surfactants such as Cocamidopropyl Betaine, enabling effective control of foam, viscosity, and overall formulation performance. AOS-92 is widely used in concentrated personal care products, industrial cleaning, and detergent formulations.

Key Functions

Alpha Olefin Sulfonate 92% provides strong cleansing, stable foam, and mildness, making it suitable for frequent-use personal care products and concentrated industrial formulations. Its versatility allows formulators to create products that are effective, mild, and environmentally friendly.

Primary Cleansing Agent
Removes oils, dirt, and residues efficiently in personal care and industrial cleaning products. AOS’s high detergency ensures effective cleaning at lower dosages, making formulations cost-effective while maintaining strong cleaning performance.
High Foam Stability
Generates abundant and long-lasting foam, which improves user perception of cleanliness. Its stable foam structure persists even in hard water or high-surfactant blends, enhancing the consumer experience in shampoos, body washes, and liquid hand soaps.
Mildness and Skin Compatibility
Gentler than many conventional sulfates, reducing irritation for sensitive skin and suitable for frequent-use formulations. When combined with co-surfactants such as Cocamidopropyl Betaine, it delivers a soft, smooth skin feel while maintaining cleansing efficiency.
Emulsification and Detergency
Efficiently disperses oils, greases, and particulate soils in aqueous solutions. This property enhances cleaning performance in both household and industrial detergents, allowing formulations to effectively handle tough stains without excessive surfactant load.
Formulation Flexibility
Compatible with amphoteric, nonionic, and other anionic surfactants. This flexibility allows precise adjustment of foam, viscosity, and sensory properties, making it suitable for a wide range of personal care and cleaning product formulations.
Environmental Performance
Biodegradable under normal environmental conditions, supporting eco-friendly product claims. It breaks down into simple substances without forming persistent pollutants, helping formulators meet regulatory and sustainability goals.

Applications

Alpha Olefin Sulfonate 92% is suitable for applications where concentrated, high-performance surfactant systems are needed. Its high active matter allows formulators to achieve strong cleaning, rich foam, and formulation efficiency in both personal care and industrial products.

Concentrated Shampoos and Hair Cleansers
Delivers rich, stable foam and effective cleansing, making it ideal for industrial or bulk formulations. High active content allows lower dosing while maintaining excellent detergency, and it can be blended with mild co-surfactants to optimize scalp comfort and hair softness.
Body Washes and Liquid Soaps
Provides mild yet effective cleansing with abundant foam. Suitable for concentrated or bulk-use products, it ensures easy dilution and consistent performance, allowing formulators to achieve desired viscosity, foam volume, and skin feel.
Industrial Cleaning Products
Used in high-performance detergents, surface cleaners, and heavy-duty cleaning systems where strong emulsification and grease removal are required. 92% AOS allows precise formulation control, reducing overall surfactant load while maintaining cleaning efficiency.
Household Detergents
Optimized for concentrated dishwashing liquids, multipurpose cleaners, and laundry pre-treatment formulations. Provides excellent foam stability, grease-cutting ability, and clarity even in hard water, balancing cleaning power with user experience.
Specialty Formulations
Suitable for applications such as car care products, foam baths, and other specialty cleaning systems where controlled foam, high detergent activity, and mildness are critical. Its high active content allows flexibility for both concentrated and ready-to-use formulations.
