АОС (Sodium Alpha Olefin Sulfonate)

Formula: R-CH=CH-(CH₂)n-SO₃Na GOST/CAS: CAS 68439-57-6

Sodium Alpha Olefin Sulfonate (AOS) is a highly efficient next-generation anionic surfactant possessing excellent emulsifying, wetting, and foaming properties. The product appears as a white or light-yellow powder (or granules/needles) and is highly soluble in water. Due to its outstanding resistance to hard water, high biodegradability, and mild effect on the skin, AOS is indispensable in the formulation of phosphate-free detergents, premium car care products, and personal care cosmetics.

Applications

Household Chemical Manufacturing: Serves as a core active surfactant for the synthesis of phosphate-free laundry powders, liquid detergents, dishwashing liquids, and hard surface cleaners.
Cosmetics and Personal Care: Used in sulfate-free formulations to create mild shampoos, shower gels, liquid soaps, and bubble baths, effectively reducing the irritation profile of traditional surfactants.
Car Care and Industrial Cleaning: Incorporated into specialized high-foaming formulations for touchless car washing, carpet cleaning, and industrial degreasing of machinery.
Construction and Oil Recovery: Applied as a highly efficient foaming agent in the production of lightweight foam concrete, as well as an enhanced oil recovery (EOR) agent in tertiary oil extraction processes.

Key Advantages

Superior Foaming and Detergency: AOS instantly generates a rich, stable, and dense foam even in hard water and at low temperatures, effectively removing tough grease, oil, and carbon stains.
Excellent Stability and Compatibility: Demonstrates outstanding synergy with other anionic, non-ionic, and amphoteric surfactants. It remains stable across a wide pH range and is fully compatible with enzymes.
Dermatological Mildness: Compared to conventional surfactants like Sodium Lauryl Sulfate (SLS), AOS is significantly less irritating to the skin and mucous membranes, preserving the natural hydrolipid barrier.
Eco-Friendliness and Biodegradability: A fully biocompatible, endogenous component. The product mineralizes rapidly and nearly 100% in wastewater, making it environmentally safe and compliant with modern "green" standards.

Storage & Transportation
