Stepan Company, a global producer of specialty and intermediate chemicals, announced a 25 percent increase in its annual production capacity for Alpha Olefin Sulfonates (AOS), reinforcing its commitment to meeting rising customer demand.
The production boost is the result of targeted capital investments and process improvements across several of Stepan鈥檚 manufacturing sites. These enhancements were carried out at its facilities in Millsdale, Illinois; Anaheim, California; and Winder, Georgia 鈥� home to the most extensive network of AOS-producing sites in North America.

Alpha Olefin Sulfonates are widely used surfactants valued for their effectiveness and environmental profile. Common applications include personal care items such as shampoos, body washes and facial cleansers, as well as household cleaners like dishwashing liquids and daily shower sprays. AOS is particularly favored for its robust foaming, fat-dissolving performance and mildness on the skin.
As consumers increasingly demand sulfate-free and eco-friendly formulations, AOS has become a popular alternative among formulators. The surfactant鈥檚 ability to generate dense, stable foam makes it ideal for products that aim to deliver a luxurious cleansing experience. In addition to personal and home care applications, AOS also serves as a key ingredient in industrial sectors including oilfield services, agriculture, construction, and emulsion polymerization.
