The α-alkyl ester sulfonate, anionic surfactants are a potentially important class of sustainable surfactants for a wide range of applications. Understanding their individual adsorption properties and the mixtures behavior along with multilayer forming at the air water interface with multivalent counterions binding is key to their exploitation.<br/>In this presentation, I will discuss the adsorption behavior of a series of α-alkyl ester sulfonate with a various of chain length from C14 to C18 and the size of the head group from methyl ester to Propyl ester to demonstrate the role and importance of the surfactant molecular structure in determining the nature of the surface adsorption in the presence of different electrolytes and in the tendency to form extended surface multilayer structure.<br/>
