Application of Linear Alkylbenzene Sulfonic Acid (LABSA)

LABSA's combination of strong cleansing, foaming, and emulsifying performance at low cost makes it the workhorse anionic surfactant of the global detergent industry:

  • Laundry Detergents (Powder and Liquid): the dominant primary surfactant in mass-market laundry products, where strong cleansing on oily and protein-based stains is essential
  • Dishwashing Liquids: key active in hand dishwashing formulations, valued for grease cutting and foam longevity
  • Hard Surface Cleaners: core surfactant in floor cleaners, all-purpose cleaners, and bathroom cleaning products
  • Industrial and Institutional Cleaning: functions across heavy-duty cleaning, including degreasers and metal cleaning chemicals
  • Hand Wash and Toilet Soaps: used in the lower-cost end of household cleansing products
  • Agrochemical Formulations: acts as a wetting agent and emulsifier in pesticide and herbicide formulations
  • Oil & Gas Applications: reduces surface tension in drilling fluids and enhanced oil recovery formulations
  • Textile Processing: used as a wetting and scouring agent in textile finishing
  • Emulsion Polymerization: functions as an anionic emulsifier in latex and polymer production

About Linear Alkylbenzene Sulfonic Acid (LABSA)

LABSA holds a quiet distinction worth knowing: it is the single highest-volume synthetic surfactant produced globally. That scale exists for a straightforward reason. LABSA delivers strong cleansing and foaming performance at a lower cost than nearly any alternative anionic surfactant, which is why it sits at the active core of mass-market detergents from laundry powders to dishwashing liquids worldwide.


The product is supplied as a strongly acidic liquid and is almost always neutralized in-formulation with caustic soda or another alkali to form the active sodium salt (sodium linear alkylbenzene sulfonate, often abbreviated as Na-LAS) that actually does the cleaning in the finished product. This two-step "acid in, salt out" reality shapes how detergent makers work with LABSA at industrial scale, and it's why active content, color, and free-acid content matter so much in supplier selection.


LABSA's linear molecular structure is also what defines its environmental profile. The older branched alkylbenzene sulfonates that LABSA replaced in the 1970s were banned across most markets due to poor biodegradability. Modern LABSA breaks down readily under standard environmental conditions, which is why it remains the surfactant of choice even as sustainability standards have tightened. Procurement teams placing bulk orders track the LABSA price closely since it typically represents the single largest raw material cost line in detergent manufacturing.


Manufacturing Process of LABSA

LABSA is produced through sulfonation of Linear Alkylbenzene (LAB). The most common industrial process uses sulfur trioxide (SO3) as the sulfonating agent in a falling-film reactor, where the LAB is spread into a thin film over a cooled surface and reacted with SO3 gas under tightly controlled conditions.


The falling-film configuration is the technical hallmark of high-quality LABSA production. By controlling film thickness, residence time, and heat removal carefully, producers minimize the formation of free sulfuric acid, free oil, and color bodies, all of which would otherwise compromise the finished product. The resulting sulfonated material is then aged to complete the reaction and dispatched as 96% active LABSA.


LAB itself, the feedstock, is a petrochemical produced from benzene and linear paraffins via Friedel-Crafts alkylation. The linear alkyl benzene price is the dominant upstream cost driver for

LABSA, and movements in LAB carry through almost one-for-one into LABSA economics. Every shipment Elchemy supplies is tested for active matter, free oil, free sulfuric acid, and color before dispatch, with a Certificate of Analysis travelling alongside each order.


LABSA Price: Bulk Pricing for Detergent and Cleaning Manufacturers

If you're looking for current LABSA pricing for bulk procurement, Elchemy provides quotes based on your specific requirements. Fill out the quote request form with the required details, such as volume, grade, color specification, destination, and any other relevant information about your procurement, and our team will revert with a detailed offer within 24 to 48 hours.


LABSA pricing tracks Linear Alkylbenzene (LAB) feedstock costs more tightly than most surfactant pricing tracks any single input. Because LAB is petrochemical-derived, it moves with crude oil and benzene markets, which means the LABSA chemical price can shift meaningfully from quarter to quarter. Sulfonation energy, freight, and grade specification layer on top of the LAB base cost.


For comparison-shopping across suppliers, procurement teams normalize to active content. The linear alkyl benzene sulfonic acid price quoted by different suppliers can vary in apparent rate but converge on a per-unit-of-active basis once 96% active matter and quality parameters are factored in.


The LABSA 96 price is the most commonly referenced commercial benchmark, since 96% active is the dominant globally traded grade. The actual rate depends on volume, color and free-acid specification, contract structure, and destination.


For an exact rate, none of these references replace a direct quote. The actual price depends on grade specification, volume, contract structure, and destination, all of which the quote process captures.


Packaging & Logistics

LABSA ships in HDPE drums for standard orders, with IBC totes and bulk tankers available for larger commercial volumes, based on buyer requirements. The product is strongly acidic and viscous at room temperature; tanker shipments require buyer-side receiving infrastructure compatible with acid-resistant materials (typically HDPE, FRP, or rubber-lined steel).


For US-bound orders, domestic stock from our US warehouses supports faster fulfillment. If sourcing is required from India or other origin countries, transit times typically run 24 to 28 days to the

US East Coast and 18 to 22 days to the West Coast. Elchemy offers FOB, CIF US port, and DDP terms, depending on how your procurement team prefers to handle landed cost and customs.


Store LABSA in tightly sealed containers in a cool, well-ventilated area, away from direct sunlight, heat, alkalis, oxidizers, and incompatible metals such as aluminum and zinc. Prolonged cold storage can increase viscosity to the point where dispensing becomes difficult, so above-freezing storage is recommended. Standard dispatch follows agreed contract terms.


Why Choose Elchemy as a Trusted LABSA Supplier?

Elchemy supplies high-purity LABSA at consistent 96% active matter, with low-color and reduced-free-acid grades available for premium formulations and transparent liquid detergent applications. Every batch ships with a Certificate of Analysis covering active matter, free oil, free sulfuric acid, and color against the grade specification.


For US buyers, domestic stock from our US warehouses cuts lead time when timelines are tight. LABSA is TSCA-listed and ships with a GHS-aligned SDS (OSHA HazCom 2012). Halal, Kosher, and vegan-compliant grades are available on request for formulators serving specific market segments. Flexible Incoterms (FOB, CIF, or DDP) give your procurement team room to structure the deal the way it works best.


Elchemy ships into 40+ countries with samples available for qualification before any bulk order, and pricing based on grade, color specification, volume, destination, and contract terms.


Safety & Handling

LABSA is a strong organic acid and requires careful handling at every stage. The concentrated 96% material causes severe burns on skin and eye contact and should be treated as a hazardous industrial chemical. For US transport, LABSA falls under DOT Hazmat Class 8 (Corrosive), UN2586 (Alkylsulphonic acids, liquid), Packing Group III.


Handlers should wear chemical-resistant gloves, splash goggles or a face shield, closed footwear, and chemical-resistant clothing rated for acid handling. If contact occurs, flush the affected area with water for at least 15 minutes and seek medical attention.


The neutralization step (combining LABSA with caustic soda or other alkali during formulation) is strongly exothermic and must be carried out under controlled mixing with adequate cooling. Adding LABSA to alkali too quickly can cause splashing, foaming, and dangerous temperature spikes.


Store LABSA in tightly sealed containers in a cool, well-ventilated area, away from alkalis, oxidizers, and reactive metals such as aluminum and zinc. Containers should be made of HDPE, FRP, or rubber-lined steel; carbon steel is not suitable for LABSA storage.


The full 16-section GHS-aligned SDS is available alongside material orders for reference by EHS and operations teams.
