  1. Property

Linear Alkylbenzene Sulphonic Acid (LABSA) is an anionic surfactant. With decontamination, wetting ,foaming, emulsification, dispersion and other properties. This product has strong detergency, good foaming power and good foam stability. It has good stability in acidic, alkaline and some oxides (such as sodium hypochlorite, peroxide, etc.), and is compatible with other surfactants and auxiliaries.


  1. Application

Linear alkylbenzene sulfonic acid (LABSA) is the largest-volume synthetic surfactant because of its relatively low cost, good performance, the fact that it can be dried to a stable powder and the biodegradable environmental friendliness as it has straight chain.


Linear Alkylbenzene Sulphonic Acid (LABSA)  is used as raw materials for the production of various detergents and emulsifiers, such as washing powder and tableware detergent in daily chemical industry, cleaning agent in textile industry, dyeing auxiliary agent, degreasing agent in electroplating industry and leather industry, and deinking agent in paper industry.


Linear alkylbenzene sulfonic acid (LABSA) is prepared commercially by sulfonating linear alkylbenzene (LAB). Linear alkylbenzene sulfonate (LAS), the world’s largest-volume synthetic surfactant, which includes the various salts of sulfonated alkylbenzenes, is widely used in household detergents as well as in numerous industrial applications. The LABSA market is driven by the markets for LAS, primarily household detergents. Linear alkylbenzene sulfonate was developed as a biodegradable replacement for nonlinear (branched) alkylbenzene sulfonate (BAS) and has largely replaced BAS in household detergents throughout the world.
