AI Overview
Alpha Olefin Sulfonate (AOS) is manufactured by sulfonating alpha-olefins with sulfur trioxide (
), followed by neutralization with caustic soda and hydrolysis. This process creates a mixture of alkene sulfonates and hydroxyalkane sulfonates, which are then bleached for color, resulting in a high-foaming surfactant suitable for detergents and personal care products.

How to make AOS powder?
α- Olefin sulfonate, pure water, caustic soda, hydrogen peroxide solution, and buffer are pumped to the neutralization reactor, after high-speed mixing, materials were pumped to the two heat exchangers and a hydrolyzer in sequence. After hydrolyzed, the finished product AOS is produced.

What is the structure of AOS?
The chemical structure of AOS consists of a hydrophilic (water-attracting) sulfonate group attached to a lipophilic (oil-attracting) alkyl chain. This dual nature allows AOS to effectively bridge the gap between water and oil-based substances, making it highly versatile.Sep 29, 2023
