Surface rheological properties of an aqueous solution of SDS (anionic) and polyoxyethylene lauryl ether (nonionic surfactant) mixture were studied. As the surfactants were blended, the surface tension was remarkedly reduced. When the nonionic surfactant was added to the anionic surfactant, the surface tension was minimized at an optimum blending ratio. Also, dynamic surface tension has the same trend with the equilibrium surface tension for the blend ratio. Marangoni-Gibbs stabilizing effect was reduced as the nonionic surfactant added to the anionic surfactant, while foam stability was reduced.
