QUICK LINKS

Linear alkylbenzenesulfonic acid is an anionic surfactant that functions as a cleaning agent and emulsifier in experimental applications. It acts by reducing the surface tension of water, allowing it to spread more easily and penetrate into the fabric or surface being cleaned. At the molecular level, it interacts with hydrophobic substances, such as oils and grease, by surrounding them and forming micelles, which can then be easily rinsed away. Linear Alkylbenzenesulfonic Acid′s mechanism of action involves disrupting the intermolecular forces between the dirt and the surface, facilitating the removal of contaminants.
