Linear Alkyl Benzene Sulfonate LAS Industrial Surfactant Raw Material

Linear Alkyl Benzene Sulfonic Acid (LABSA, CAS:42615‑29‑2, molecular formulais a high‑performance anionic surfactant raw material produced via sulfonation reaction of linear alkyl benzene (LAB) with sulfur trioxide, followed by aging and refining process. It appears as light yellow to brown viscous oily liquid, with slight characteristic sulfur‑acid odor, easily soluble in water and ethanol, insoluble in ether. After neutralization with alkali, it generates alkylbenzene sulfonate salt with excellent surface‑active performance. Compared with branched‑chain alkyl benzene sulfonic acid, linear‑chain structure provides better biodegradability, strong detergency and outstanding hard‑water resistance. Thanks to its excellent decontamination, emulsification, foaming and wetting capability, it has become the most mainstream raw material for detergent industry, complying with industrial surfactant specifications. Our production adopts continuous SO₃ film sulfonation technology to strictly control free oil, inorganic acid and impurity indicators, stable active content, widely applied across daily‑chemical detergent manufacturing, textile processing, leather degreasing, pesticide emulsifier and fine chemical synthesis fields。

Applications
Daily‑Chemical Detergent Industry (Core Consumption Field): It is the key raw material for producing various domestic and industrial cleaning products. After neutralization with sodium hydroxide, it is widely used for laundry powder, liquid laundry detergent, dish‑washing liquid and multi‑purpose cleaners. It delivers powerful grease‑removing, foaming and anti‑hard‑water performance. For acidic toilet cleaners and scale‑removal detergents, it can be directly formulated without full neutralization to provide both cleaning and certain descaling effect. It is also the core feedstock for producing sodium alkyl benzene sulfonate, ammonium salt and ethanolamine salt derivatives
Textile Printing & Dyeing Industry: Applied as wetting agent, scouring agent and detergent for textile fabric pretreatment. It removes textile oil stains and impurities on fiber surface, improves dye permeability and uniformity, reduces fabric color‑spot risk; also used for textile waste‑water de‑oiling treatment.
Leather Processing Industry: Acts as efficient degreasing agent for raw leather. It dissolves and disperses animal fat on leather surface, improves leather penetration for subsequent tanning agent, optimizes finished leather softness and grain quality.
Pesticide & Emulsifier Formulation: Serves as emulsifier and dispersant raw material for pesticide EC formulations. It assists pesticide active ingredients to disperse stably in water phase, improve suspension stability of spray liquid and enhance drug efficacy.
Fine Chemical and Other Fields: Important intermediate for synthesis of various anionic surfactant derivatives; also used for industrial metal surface degreasing, paper‑making de‑inking agent, and amino baking paint curing catalyst in coating industry
