Direct supply from state-of-the-art chemical synthesis bases, ensuring global formulation compliance and optimized supply chain efficiency.
The global daily chemical, surfactant, and cleaning agent sectors are undergoing a massive transition. Due to tightening regulatory frameworks in the European Union (REACH) and United States EPA regarding 1,4-dioxane limits in personal care and detergent formulations, traditional surfactants like Sodium Laureth Sulfate (SLES) are being thoroughly scrutinized. This has driven global brand owners and formulators directly toward high-performance, eco-friendly anionic surfactants: Sodium Alpha Olefin Sulfonate (AOS).
AOS is prepared through the continuous gas-phase sulfonation of C14-C16 alpha-olefins with sulfur trioxide, followed by rapid neutralization with sodium hydroxide. The resulting compound features outstanding foaming characteristics, strong calcium ion tolerance, high compatibility with hard water conditions, and a rapid biodegradation rate. Unlike alkoxylated surfactants, AOS synthesis completely bypasses ethoxylation, making it inherently 1,4-dioxane-free. This fulfills the primary criteria of contemporary clean beauty initiatives and green home care formulations globally.
• Active Matter: Available in 92% Min (Powder/Needle) and 35% (Liquid) states.
• Chemical Structure: Comprises sodium alkene sulfonates and sodium hydroxyalkane sulfonates.
• pH Stability: High chemical stability over a broad pH range (2 to 12).
• Hard Water Tolerance: Exceptionally low sensitivity to water hardness minerals, preventing precipitation in mineral-dense zones.
Leveraging advanced continuous sulfonation machinery, integrated raw material pipelines, and Suzhou's robust logistics hub.
Our facilities employ state-of-the-art continuous multi-tube falling film sulfonation reactors. This technology guarantees uniform SO3 concentration distribution, minimizing secondary byproducts (such as free oil and sodium sulfate) and maintaining color consistency.
Our dedicated application laboratories provide customization on active ingredient levels, physical state (powder, needle, or liquid), and pH adjustment. We also formulate custom synergistic surfactant packages (e.g., AOS-APG-CAB blends) for global clients.
Located in Suzhou, near major international deep-water terminals (Shanghai and Ningbo-Zhoushan ports), we facilitate seamless container shipping, customs clearance, and just-in-time delivery schedules to minimize transit delays.

As clean beauty, safety regulations, and efficiency dictate manufacturing choices, several key trends have emerged in the surfactant industry:
In-depth technical answers addressing common inquiries from chemical engineers, formulators, and supply chain managers.
Sodium Alpha Olefin Sulfonate (AOS) is a sulfonation derivative of linear alpha-olefins, while Sodium Laureth Sulfate (SLES) is ethoxylated prior to sulfonation. The primary difference lies in the hazard profile and regulation: SLES synthesis can generate trace 1,4-dioxane (a carcinogen), requiring stripping steps. AOS is synthesised without ethoxylation, making it naturally 1,4-dioxane-free. Additionally, AOS has higher hard-water stability and biodegradability compared to SLES.
AOS exhibits high calcium and magnesium ion tolerance. In regions with hard water (high mineral content), traditional soaps and some sulfates precipitate, forming scum and reducing foam volume. AOS maintains its wetting, emulsifying, and foaming performance in hard water conditions, making it an excellent choice for globally distributed detergents.
Yes. AOS is highly biodegradable, breaking down rapidly under aerobic conditions. It does not bioaccumulate in aquatic organisms, conforming to the sustainability and green chemistry standards set by regulatory bodies such as the EU and US EPA.
Absolutely. AOS is available in 92% high-active powder and needle formats. These dry solid formats are widely used in syndet bars, solid shampoo bars, tablet detergents, and powdered bubble baths, where moisture content must be kept to a minimum.
Under dry, ventilated conditions at temperatures below 30°C, solid AOS (powder/needle) has a shelf life of 24 months. For liquid AOS (35% concentration), prevent exposure to freezing temperatures (below 10°C) to avoid crystallization. Ensure packaging remains sealed to prevent moisture absorption and caking in powder products.
