Alpha Olefin Sulfonate Price and Production Outlook
Global alpha olefin sulfonate (AOS) production in 2025 is estimated at 3 to 4 million tonnes, positioning AOS as a high-volume anionic surfactant integral to the global detergents and cleaners market. Supply growth is driven by rising household detergent consumption, expansion of personal care products, and substitution away from less biodegradable surfactants.
Market conditions balance large-scale continuous production with volatile petrochemical feedstock costs and increasing environmental compliance requirements. Pricing is closely linked to alpha olefin availability, sulfur costs, energy pricing and plant utilisation rates. The global picture shows steady, consumption-led growth, aligned with population expansion, urbanisation and hygiene awareness.
Production leadership is concentrated in Asia Pacific, followed by North America and Europe, where integrated petrochemical infrastructure supports cost-efficient sulfonation. Many developing regions remain import dependent due to capital intensity and technical complexity.
Buyers prioritise consistent active matter, colour stability, foaming profile and formulation compatibility.
Key Questions Answered
