Linear Alkyl Benzene Sulfonic Acid (LABSA), also known as LAS Acid, Dodecylbenzene Sulfonic Acid, Acid Slurry, and Alkyl Benzene Sulfonate Acid, is one of the most widely used anionic surfactants in the world. Due to its high detergency, excellent foaming ability, emulsifying properties, and biodegradability, LABSA serves as a key raw material in the detergent and cleaning industries.
