Premium raw materials certificated by global industry standards, providing high-performance formulations for diverse manufacturing needs.
Linear Alkylbenzene Sulfonate (LAS) is the most volume-significant synthetic surfactant globally. Obtained through the sulfonation of Linear Alkylbenzene (LAB) with sulfur trioxide (SO3), it is primarily commercialized as 96% Linear Alkylbenzene Sulfonic Acid (LABSA) or neutralized into sodium salts (Na-LAS). Its molecular structure consists of a hydrophobic linear alkyl chain (typically C10 to C13) attached to a hydrophilic benzene sulfonate group.
Unlike branched counterparts, the linear hydrocarbon profile of LAS guarantees highly rapid biodegradation pathways under aerobic conditions, satisfying strict environmental criteria across North America, the European Union, and East Asia. Key properties include:
How Suzhou Yuantairun Chemical Co., Ltd. leverages state-of-the-art manufacturing plants to secure bulk material resilience and chemical batch-to-batch consistency.
Our collaborative production units leverage computerized DCS (Distributed Control Systems) for benzene alkylation and multi-tube falling film sulfonation. This limits the formation of free sulfuric acid and maintains active content at an exact, reproducible concentration (96% min for LABSA).
Every shipment undergoes HPLC, GC, and colorimetric tests to monitor raw material color indexes (keeping APHA color below 50). This guarantees that finished detergents or personal care formulations maintain their intended transparency, consistency, and stability over time.
With integrated logistics hubs in Suzhou and primary export portals (Shanghai/Ningbo ports), we deploy real-time transit tracking. By using modern flexitanks, IBC totes, and steel drums, we prevent temperature-induced crystallization during oceanic logistics.

Key Value: High tolerance in extremely alkaline/acidic systems, ensuring no phase separation under high shear stresses.
As regulatory and environmental guidelines tighten globally, the chemical industry is shifting from petrochemical-based Linear Alkylbenzene (LAB) toward bio-based alternatives. Our technological roadmap focuses on two main strategies:
1. Bio-Based Paraffins: Transitioning toward bio-paraffin raw materials derived from certified renewable agricultural waste and vegetable lipids. The resulting "Bio-LAS" maintains identical performance profiles to standard LAS while significantly lowering cradle-to-gate carbon footprints.
2. Advanced Surfactant Blends: Hybrid surfactant systems that pair Alkylbenzene Sulfonate with green co-surfactants like Alkyl Polyglucosides (APG0810, Cocoyl Glucoside) and mild amino acids (Sodium Cocoyl Apple Amino Acids). These synergies reduce active concentration requirements by up to 20% while maintaining the same washing performance.
Ensuring frictionless importing, trade compliance, and tailored technical support for international buyers.

Alkylbenzene Sulfonic Acid (LABSA) is the raw acid form (active content typically 96% min). Neutralizing it with sodium hydroxide (NaOH) or triethanolamine (TEA) yields the sodium or amine salt (Alkylbenzene Sulfonate - LAS). LAS is the neutral, ready-to-use surfactant form integrated into end-consumer cleaning formulations.
Shorter carbon chains (C10-C11) show better solubility, faster wetting kinetics, and higher foam volumes at lower temperatures. Longer carbon chains (C12-C13) provide stronger soil removal, emulsification, and lipid-binding properties in warm-water wash cycles. We customize the homologue distribution ratio to align with your targeted washing parameters.
We use high-purity Linear Alkylbenzene (LAB) and monitor exact sulfonation reaction temperatures. This precise control limits oxidation and carbonization side-reactions, yielding a light-yellow liquid with a low color index (typically < 50 Klett/APHA) that won't discolor clear liquid detergents.
Standard packaging includes 210kg HDPE plastic drums, 1000kg IBC containers, or 24MT flexitanks. The product has a shelf life of at least 12 months when stored in a dry, well-ventilated warehouse between 15°C and 40°C. Storage below 15°C may require gentle warming to dissolve potential crystallization before pump transfer.
Yes. Pairing LAS with nonionic surfactants like Alkyl Polyglucosides (APG0810, APG1214) or Cocoyl Glucoside creates a highly effective synergetic micellar structure. This combination boosts foam volume, increases tolerance to water hardness, and reduces overall skin irritation profiles.
Every shipment is accompanied by a Certificate of Analysis (COA), Technical Data Sheet (TDS), and a detailed SDS compliant with global GHS guidelines. Depending on market destination, we also offer REACH verification documents, RSPO supply-chain certificates, and Halal clearances.
