Sodium C14 C16 Alpha Olefin Sulfonate (commonly referred to as AOS C14-C16, CAS No. 68439-57-6) is a highly versatile, biodegradable anionic surfactant. Primarily produced via the continuous gas-phase sulfonation of C14-C16 alpha-olefins with sulfur trioxide (SO3), followed by rapid neutralization, it consists mainly of sodium alkene sulfonates (60-65%) and sodium hydroxyalkane sulfonates (35-40%).
As leading suppliers and an established China factory, Suzhou Yuantairun Chemical Co., Ltd. ensures precision control over free oil, residual inorganic salts, and pH values. Our advanced manufacturing routes prevent the accumulation of 1,4-Dioxane—a common concern with ethoxylated surfactants such as SLES—making our AOS the ideal candidate for eco-conscious formulations.

Direct-from-factory pricing combined with automated continuous sulfonation ensures highly competitive unit economics.
Strategic warehouse positioning near key export ports ensures seamless shipping and reliable supply chains.
Pioneering cleaner processes and next-generation chemical engineering for sustainable cleaning agents.
Our facility utilizes state-of-the-art multi-tube falling film reactors. Liquid C14-C16 alpha-olefins descend inside vertically arranged tubes, forming a uniform thin film. Concurrently, a diluted stream of gaseous sulfur trioxide (SO3) flows through the tubes, triggering rapid, highly exothermic sulfonation.
Because the reaction is instantaneous, temperature control is critical to prevent color degradation and byproduct formation. The subsequent steps include continuous digestion, neutralization with sodium hydroxide (NaOH), and hydrolysis at high temperature (140°C - 160°C) to convert intermediate sultones into highly active sodium alkene sulfonates and hydroxyalkane sulfonates.
Driven by eco-regulations, the surfactant industry is transitioning away from petroleum-based feedstocks. Our R&D division is focused on bio-based alpha-olefins derived from renewable plant oils, ensuring identical chemical performance with a smaller carbon footprint.
Furthermore, we are optimizing the hydrolysis phase to lower residual 1,4-sultone and 2-sultone levels. This ensures our AOS meets stringent safety regulations for baby products and sensitive skin formulas worldwide, laying the groundwork for clean-label, bio-based cosmetics.
How Sodium C14 C16 Alpha Olefin Sulfonate drives performance across sectors.
By combining SLES (Sodium Laureth Sulfate) and AOS (Sodium Alpha-Olefin Sulfonate) as core surfactants, formulators achieve superior stain removal and stable foam profiles.
AOS improves cold-water soil removal and disperses hard-water minerals. In combination with CMEA thickeners, it yields stable, high-viscosity liquid laundry detergents that perform exceptionally across water temperatures.
AOS C14-C16 serves as a primary foaming agent in sulfate-free shampoos and mild body washes. When paired with amino acid surfactants like Sodium Cocoyl Glutamate and Sodium Lauroyl Sarcosinate, it produces a rich, micro-cellular lather without drying out skin or hair.
It is less prone to damaging hair lipids compared to SLS, helping maintain the integrity of hair fibers and color.
Industrial degreasers require surfactants that maintain performance in highly alkaline or acidic environments. AOS C14-C16 remains chemically stable across a broad pH range and resists hydrolytic degradation.
It shows exceptional synergy with LAS (Linear Alkylbenzene Sulfonate) and nonionic APG products, rapidly breaking down heavy grease, oil, and mineral deposits on machinery and vehicles.
Proven formulations designed to address real-world challenges across household, personal care, and industrial cleaning sectors.
