Linear alkyl benzene sulphonic acid 90% manufacturers

Buyers must prioritize the Active Matter content, which should be strictly 90% or higher. Key parameters include Free Oil (Unsulfonated matter) which should be below 2.0% to ensure product stability, and Free Sulfuric Acid, typically kept under 1.5% to prevent excessive acidity. Additionally, check the color (Klett); a lower Klett value (usually <50) indicates higher purity and better suitability for light-colored detergent formulations.

LABSA 90% is a high-concentration anionic surfactant primarily used in the production of household detergents, including washing powders, liquid soaps, and dishwashing liquids. It is also widely utilized in industrial cleaning agents, textile processing as a mercerizing or washing agent, and in the leather industry for degreasing. Its high activity makes it economically efficient for long-distance shipping as you transport less water compared to the 70% grade.

As a corrosive chemical (Class 8), LABSA must have a valid Material Safety Data Sheet (MSDS) compliant with GHS standards. For the EU market, REACH registration is mandatory. Ensure the supplier provides a Certificate of Analysis (COA) for every batch. Furthermore, packaging must meet UN-certified standards (usually plastic drums or IBC tanks) to ensure safety during maritime transit.

Using the 90% grade offers significant savings on logistics and storage compared to lower concentrations. However, it requires precise neutralization equipment (usually with Caustic Soda) during production. Buyers should calculate the cost per active unit rather than the price per metric ton to accurately compare suppliers. Made-in-China.com features verified manufacturers who provide tiered pricing for bulk orders, often reducing costs by 5-10% for full container loads (FCL).

The biggest risks are concentration dilution and heavy metal contamination. Some suppliers may provide 80-85% concentration labeled as 90%. To mitigate this, always request a pre-shipment inspection (PSI) by third parties like SGS or Intertek. Another risk is leakage during transit; ensure the contract specifies new, UV-stabilized HDPE drums to prevent chemical degradation or container damage.

For liquid chemicals, CIF (Cost, Insurance, and Freight) is often preferred for new buyers as the supplier handles the complex hazardous goods export licenses in China. However, experienced buyers may prefer FOB (Free on Board) to control freight costs. Always confirm the Lead Time, which for LABSA is typically 7-14 days, and ensure the supplier is located near major chemical ports like Qingdao, Tianjin, or Shanghai to minimize inland transit risks.

Use Secured Payment services provided by platforms like Made-in-China.com to ensure funds are only released upon proof of shipment (Bill of Lading). For first-time orders exceeding $50,000, consider a Letter of Credit (L/C). Avoid suppliers who insist on 100% T/T upfront; a standard industry deposit is 20-30%, with the balance paid against the copy of the B/L.

Check for Anti-dumping duties in your specific country, as some regions impose extra taxes on Chinese surfactants. Ensure the supplier provides a Generalized System of Preferences (GSP) Certificate of Origin or Form E (for ASEAN countries) to benefit from reduced or zero import tariffs under relevant Free Trade Agreements.
