LABSA (Linear Alkylbenzene Sulphonic Acid), also known as Dodecylbenzenesulphonic acid, bears the CAS number 27176-87-0 and the UN number 2586. LABSA is a significant organic strong acid and an intermediate for anionic surfactants. It typically appears as a viscous, brownish, oily liquid and serves as the most crucial raw material for producing various sulfonate surfactants. LABSA is primarily manufactured by sulfonating Linear Alkylbenzene (LAB) with sulfur trioxide. Its molecular structure features both a lipophilic alkyl chain and a hydrophilic sulfonic acid group, granting it excellent surfactant properties. It is one of the cornerstones of the modern detergent and cleaning chemical industry.
