A systematic breakdown of structural properties, chemical characteristics, and process dynamics that define AOS as the ultimate anionic surfactant for next-generation formulations.
Sodium Alpha Olefin Sulfonate (AOS) is a high-performance anionic surfactant produced by the continuous sulfonation of C14-C16 alpha-olefins with sulfur trioxide (SO₃), followed by rapid neutralization with sodium hydroxide (NaOH) and subsequent hydrolysis. The resulting chemical structure contains a mixture of sodium alkenyl sulfonates and sodium hydroxyalkane sulfonates.
This unique chemistry confers excellent wetting, foaming power, detergency, and calcium ion tolerance. Unlike traditional alkyl ether sulfates (such as SLES), AOS contains no ethoxyl groups, eliminating the risk of 1,4-dioxane contamination, making it a pivotal alternative for green and clean beauty concepts.
Our industrial production lines output AOS in both powder and liquid states, aligning with different rheological requirements and processing designs of our global buyers. Below are the key specifications:
| Test Parameter | AOS 92% (Powder / Needle) | AOS 35% (Liquid) |
|---|---|---|
| Appearance | White or light yellow powder/needle | Light yellow transparent liquid |
| Active Matter (%) | ≥ 92.0 | 35.0 ± 1.0 |
| Free Oil / Unsulfonated Matter (%) | ≤ 3.0 | ≤ 1.5 |
| Sodium Sulfate (%) | ≤ 5.0 | ≤ 1.5 |
| pH Value (1% aqueous solution) | 9.0 - 11.5 | 9.0 - 11.5 |
| Color (Klett, 5% active matter soln) | ≤ 90 | ≤ 60 |
Suzhou Yuantairun Chemical integrates local structural supply line strengths to provide consistent, scalable material streams directly to your industrial sites.
Our factories maintain strategic partnerships with domestic petro-chemical and oleo-chemical upstream suppliers, ensuring continuous access to key alpha-olefins (C14-C16) and processing agents even during global supply chain fluctuations.
Our plants leverage multi-tube falling film sulfonation reactors that offer high reaction yields, tight temperature regulation, and low residual free oils, generating stable raw materials across batches.
Located in the Yangtze River Delta industrial hub (Suzhou/Shanghai), our facility guarantees swift customs clearance, instant multimodal routing, and minimal overland freight times to key oceanic ports.
Deploying safe, certified, and compliant chemicals across global borders requires rigorous oversight and administrative precision.
We comply fully with key market regulatory protocols to ensure seamless importation and formulation approval processes:
Through logistics partnerships, we offer localized clearing and buffer stocks in major European and North American hubs to bypass long shipping cycles.
Our global engineering desks offer formulation guidance, dosage optimizations, and physical-chemical troubleshooting to help your teams cut lead times.

The global anionic surfactant market is shifting towards sulfate-free, eco-friendly alternatives. Due to its clean profile and absence of ethylene oxide adducts, Sodium Alpha Olefin Sulfonate (AOS) is gaining significant market share from conventional alkyl sulfates (SLS/SLES).
Key drivers accelerating the global adoptability of AOS include:
Get quick answers to common technical, shipping, and processing questions about Sodium Alpha Olefin Sulfonate.
Sodium Alpha Olefin Sulfonate (AOS) is ethoxylation-free, making it completely free from 1,4-dioxane. AOS also displays superior calcium ion tolerance and hydrolytic stability in acidic environments, whereas SLES can undergo gradual acid-catalyzed hydrolysis.
AOS exhibits high calcium and magnesium ion tolerance compared to standard anionic surfactants. Its foaming and wetting efficiency remain high even in hard water, eliminating the need for high chelating agent concentrations in formulations.
AOS 92% powder has a standard shelf life of 24 months when stored in unopened original packaging. It should be kept in a cool, dry, well-ventilated warehouse away from direct sunlight, moisture, and high temperatures to prevent compaction or clumping.
Yes. We offer standard packaging in 25kg bags (for powder/needle grades) and 200kg drums or 1000kg IBC tanks (for 35% liquid grades). Customized weights and private labeling can be arranged for bulk contract orders.
