Linear alkyl benzene

When evaluating LAB, the most critical technical specifications are Bromine Index, Sulfonability, and Alkyl Chain Distribution. A low Bromine Index (typically <10 mg/100g) indicates high purity and low olefin content, which prevents unwanted side reactions during sulfonation. You should also verify the Average Molecular Weight (typically 231-242) to ensure it meets your specific detergent formulation requirements for solubility and foaming performance. Always request a Certificate of Analysis (COA) for every batch to confirm the Linearity is above 92%, as higher linearity ensures better biodegradability of the final surfactants.

As a chemical precursor, LAB must comply with international safety and environmental regulations. Ensure the supplier provides a comprehensive Material Safety Data Sheet (MSDS/SDS) aligned with the GHS (Globally Harmonized System). For buyers in the EU, REACH registration is mandatory. If the end product is intended for household cleaning, verify that the LAB meets biodegradability standards (ISO 11734 or OECD 301 series). Additionally, ensure the manufacturer holds ISO 9001 for quality management and ISO 14001 for environmental management to mitigate supply chain ESG risks.

The carbon chain distribution (usually C10 to C13) determines the performance of the resulting Linear Alkyl Benzene Sulfonate (LAS). C10-C11 chains offer better solubility and cold-water performance, making them ideal for liquid detergents. C12-C13 chains provide superior detergency and grease removal, which is preferred for powder detergents and industrial cleaners. Professional buyers should specify the Carbon Distribution ratio to the supplier to ensure the raw material aligns with the specific climate and washing habits of their target market.

LAB is a stable liquid but requires specific handling to maintain purity. It should be stored in carbon steel or stainless steel tanks with a nitrogen blanket to prevent moisture absorption and oxidation. Since LAB has a relatively high flash point, it is not classified as a highly flammable liquid, but it must be kept away from strong oxidizers. Ensure your logistics provider uses dedicated ISO tanks or epoxy-lined drums to avoid cross-contamination from previous chemical shipments.

LAB prices are highly correlated with crude oil and benzene feedstock costs. To mitigate risk, avoid spot buying during peak oil prices and consider long-term framework agreements with price escalation clauses. On Made-in-China.com, you can identify verified manufacturers who offer tiered pricing based on volume, allowing you to lock in rates for quarterly shipments.

Never release full payment before quality verification. Use Letter of Credit (L/C) or Trade Assurance services to protect your funds. It is highly recommended to appoint a third-party inspection agency (like SGS or Intertek) to perform pre-shipment sampling and testing at the loading port to ensure the chemical composition matches the agreed-upon COA.

For large volumes, ISO Tank containers are the most cost-effective and secure method. Ensure the supplier provides a Cleanliness Certificate for the tank before loading. For sea freight, clarify the Incoterms (preferably CIF or CFR) and ensure the maritime insurance covers chemical leakage and contamination. Always check for anti-dumping duties that your specific country may impose on LAB imports from certain regions to avoid unexpected customs costs.
