Alpha olefin sulfonate price

When sourcing AOS, the most critical parameter is the Active Matter content, typically available in 35% (liquid) or 92% (powder/needle) concentrations. Buyers must verify the Unsulfonated Matter (Free Oil) levels, which should be below 1.5% to ensure high purity and prevent formula instability. Additionally, check the Color (Hazen/APHA); a lower value indicates better refinement, which is essential for transparent liquid detergents and personal care products.

AOS is an anionic surfactant known for its excellent emulsification, decontamination, and calcium soap dispersing power. Its high biodegradability makes it a preferred choice for eco-friendly cleaning brands. In the oil industry, it is used for foam flooding due to its high-temperature resistance and salt tolerance. For the construction industry, it serves as a superior air-entraining agent for concrete, improving workability and frost resistance.

Suppliers must provide a comprehensive Material Safety Data Sheet (MSDS) and a Certificate of Analysis (COA) for every batch. For shipments to the EU, REACH registration is mandatory. If the AOS is intended for personal care products, ensure the manufacturer follows ISO 22716 (GMP for Cosmetics). Furthermore, check for ISO 9001 certification to guarantee consistent chemical stability across large-scale production runs.

To achieve the best price-to-performance ratio, consider the physical form of the product. While AOS 92% powder has a higher unit price, it significantly reduces shipping costs per unit of active matter compared to the 35% liquid version. For bulk orders, sourcing from verified manufacturers on Made-in-China.com can provide access to tiered pricing, where orders exceeding 20 tons (Full Container Load) often trigger 10-15% discounts.

The main risk is product degradation or moisture absorption during sea transit, especially for powder forms. Ensure the supplier uses moisture-proof packaging, such as multi-layer paper bags with PE liners or UN-approved plastic drums. To secure the transaction, use SGS or Intertek third-party inspections at the loading port to verify that the active matter percentage matches the contract before final payment.

AOS prices are closely linked to the cost of Alpha Olefins (petrochemical feedstock). It is advisable to negotiate long-term framework agreements with a price adjustment formula based on market indices. For spot purchases, monitor the crude oil market trends and aim to lock in prices during market dips. Always request FOB (Free On Board) pricing to maintain control over your logistics costs and avoid hidden markups in CIF quotes.

AOS is generally classified as non-hazardous for transport, but it is vital to confirm the HS Code (typically 340231) with your customs broker to determine applicable tariffs. When shipping to countries with high humidity, specify the use of desiccants inside the container. For first-time buyers, it is highly recommended to utilize the secured payment services and verified supplier audits provided by Made-in-China.com to ensure trade compliance and fund safety.
