Powdered, needle shaped products and liquid products
Sodium alpha olefin sulfonate is an anionic surfactant prepared by gas-phase membrane sulfonation and continuous neutralization of alpha olefins using sulfur trioxide. AOS has excellent emulsifying, decontaminating and calcium soap dispersing power, good solubility and compatibility, delicate and rich foam, easy biodegradation, low toxicity, little skin irritation and other characteristics, especially when used in phosphorus free detergents, it can not only maintain good washing ability, but also has good compatibility with enzymes. Powdered products have good fluidity. Therefore, it can be widely used in various household washing products such as phosphate free laundry detergent and liquid detergent, as well as in the textile printing and dyeing industry, petroleum chemicals, and industrial hard surface cleaning.
