LABSA (Linear Alkyl Benzene Sulfonic Acid)

Linear Alkylbenzene Sulfonic Acid (LABSA) is an anionic surfactant that was primarily introduced in 1964. It has been the world’s largest-volume synthetic surfactant since then. LABSA is widely used in household detergents as well as in numerous industrial applications.
Like other surfactants, LABSA is a bipolar molecule composed of both hydrophilic and hydrophobic parts. Its polar head has a negatively charged sulfonate group, and its hydrophobic part contains an alkylbenzene.
