Comprehensive technical breakdown of Linear Alkylbenzene Sulfonate (LAS) structures and optimization benchmarks.
Sodium Dodecylbenzenesulfonate (SDBS, CAS 25155-30-0), commonly classified under the broad family of Linear Alkylbenzene Sulfonates (LAS), represents one of the most powerful and versatile anionic surfactants utilized globally. Its chemical structure features a hydrophobic linear alkyl chain coupled with a highly hydrophilic sulfonated benzene ring neutralized by sodium ions. The linearity of the alkyl chain is a key determinant of its excellent biodegradability under aerobic conditions, rendering it a highly favorable option in eco-conscious cleaning formulations compared to historically utilized branched alkylbenzene sulfonates (BABS).
At Suzhou Yuantairun Chemical, we manage the sulfonation process using state-of-the-art SO3 gas-film sulfonation plants. This meticulous control yields a highly pure product with a minimal free oil content, extremely low inorganic salts (sodium sulfate), and outstanding color values. Through precise neutralization control, we produce SDBS in active matter concentrations ranging from 30% liquid pastes up to 90% highly soluble white powders and flakes, serving both liquid detergents and dry-powder washing formulations.
SDBS excels in lowering the surface tension of water, facilitating rapid wetting and emulsification of hydrophobic soils. However, in hard water environments, calcium and magnesium ions tend to interact with anionic surfactants, reducing their efficacy. To counter this, SDBS is systematically formulated alongside chelating agents like EDTA or secondary mild surfactants (e.g., Cocamidopropyl Betaine CAB-35 or Alkyl Polyglucosides APG) to create robust synergetic action.
Additionally, SDBS displays high thermal stability and works exceptionally well across a wide pH range, maintaining its washing properties under acidic, neutral, and alkaline conditions. It is also compatible with enzymes, optical brighteners, and other functional builders in heavy-duty cleaning products.

How Suzhou Yuantairun Chemical integrates automated production controls with global distribution reliability.
Our production facilities utilize advanced Distributed Control Systems (DCS) that monitor temperatures, flow rates, pressure configurations, and reactant ratios in real-time. This eliminates human error and guarantees batch-to-batch homogeneity, which is essential for multi-national chemical procurement departments. Every process step, from sulfonation to spray drying and final packaging, is fully traced with a digital footprint.
By using clean-air closed loops and dry nitrogen preservation during product storage, we completely eliminate moisture ingress issues in our SDBS powders, preventing compaction and ensuring optimal flowability during bulk container discharging at the destination port.
Located in the Yangtze River Delta chemical zone, Suzhou Yuantairun Chemical enjoys seamless multimodal connectivity to the Shanghai Port and Ningbo Port. This proximity drastically reduces domestic trucking times, lowering carbon emissions and transit expenses. We offer highly customizable container plans, matching loose bags, heavy pallets, big bags, steel/plastic drums, and specialized IBC totes with dry container desiccant controls for deep-sea shipping routes.
We work with tier-one shipping lines to offer guaranteed shipping slots and mitigate volatile maritime rate fluctuations. This provides our partners with consistent landed-cost calculations across quarters.

Sodium Dodecylbenzenesulfonate (SDBS) is the key active component and specific neutralized chemical salt (CAS 25155-30-0) within the broader family of Linear Alkylbenzene Sulfonates (LAS). LAS is an industry-wide term referring to alkylbenzene sulfonic acids that have been neutralized with basic agents. SDBS specifically highlights the sodium salt form, which is highly preferred for powder detergent dissolution and stable liquid formulation builders.
We employ continuous film sulfonation monitored by PLC and DCS systems. The ratio of raw alkylbenzene to gaseous SO3 is regulated dynamically down to fractions of a percent. Each batch undergoes rigorous testing for active matter, pH, water content, and free oil before dispatch, ensuring identical formulation behavior for our customers.
Our typical packaging options include 25kg multi-wall paper or woven plastic bags with inner PE liners to prevent moisture absorption. For liquid and paste versions of SDBS, we supply 200kg HDPE drums or 1000kg IBC tanks. We also accommodate custom pallet configurations with shrink wrap and container desiccant packs to withstand long-duration sea shipping.
Yes. By strictly utilizing linear alkyl chain architectures instead of branched structures, our SDBS meets global environmental standards. It undergoes quick aerobic and anaerobic biodegradation in wastewater plants, leaving minimal environmental impact and conforming to EU and US EPA regulations.
