China alkylbenzene sulfonate manufacturers

When purchasing Alkylbenzene Sulfonate, particularly Linear Alkylbenzene Sulfonic Acid (LABSA 96%), you must prioritize the Active Matter content, which should ideally be ≥96%. Other critical parameters include Free Oil content (≤2.0%), Inorganic Acid/Sulfuric Acid content (≤1.5%), and Color (Klett). For high-quality detergents, a Klett color value of ≤30 is preferred to ensure the final product remains clear and stable.

Verify the biodegradability of the LAS, as international standards require a rate of >90% for environmental safety. You should also request a Certificate of Analysis (COA) for every batch to check for viscosity stability and solubility in water. For industrial applications, ensure the product has excellent emulsifying and foaming properties, which are essential for its function as a primary surfactant.

Suppliers should provide a Material Safety Data Sheet (MSDS) and a Technical Data Sheet (TDS). For exports to Europe, REACH registration is mandatory. Additionally, ensure the manufacturer follows ISO 9001 Quality Management Systems and ISO 14001 Environmental Management Systems to guarantee consistent production quality and adherence to global chemical safety regulations.

It is primarily used as a raw material for household detergents, including washing powders, liquid detergents, and dishwashing liquids. In industrial sectors, it serves as an emulsifier for agricultural pesticides, a wetting agent in the textile industry, and a de-inking agent in paper recycling. Understanding your specific application helps the supplier adjust the neutralization process or concentration.

Always utilize third-party inspection services such as SGS or Intertek to conduct pre-shipment testing. On Made-in-China.com, look for Audited Suppliers who have undergone rigorous on-site verification. Requesting a pre-shipment sample that matches the bulk order's batch number is a critical step in preventing 'bait and switch' tactics.

Alkylbenzene Sulfonate is often corrosive; therefore, it must be packed in acid-resistant plastic drums (210kg/225kg) or IBC tanks (1000kg). Ensure the packaging is UN-certified for hazardous goods transport. When shipping from China, confirm the supplier's experience with IMO Class 8 (Corrosive Substances) regulations to avoid customs delays or fines at the port of entry.

Chemical prices are highly sensitive to crude oil market fluctuations and raw material (Benzene) costs. It is advisable to negotiate formula-based pricing for long-term contracts. For payment, use Secure Payment services or Letter of Credit (L/C) to protect your funds until the shipping documents and COA are verified. Bulk discounts typically apply for orders exceeding 20 Metric Tons (one 20ft container).

Focus your search on Made-in-China.com, specifically targeting manufacturers located in chemical industrial hubs like Shandong, Jiangsu, or Zhejiang provinces. Prioritize suppliers with a high 'Trust Score' and those who have been members for 5+ years, as they demonstrate long-term operational stability and experience in international trade policies.
