Micellar and Solubilization Properties of Biological Surfactant Surfactin
Journal of Surfactants and Detergents, EarlyView.ABSTRACT We studied aqueous solutions of surfactin in the concentration range of 0.001–200 g/L using NMR diffusometry, tensometry and optical microscopy methods. According to tensometry data, the system forms monolayers of surfactant molecules at the water‐air phase boundary at C = 0.02 g/L.
