The dynamic and equilibrium properties of adsorption layers of poly (oxyethylene) alkyl ether (C_nEO_m) can be well described by the reorientation model. In its classical version, it assumes two adsorption states; however, there are obviously surfactants that can adsorb in more than two possible conformations. The experimental data for C₁₄EO₄ and C₁₄EO₈ (dynamic and equilibrium surface tensions and surface dilational visco-elasticity as measured by bubble profile analysis tensiometry) are used to verify if a reorientation model with more than two possible adsorption states can better describe the complete set data of C_nEO_m adsorption layers at the water/air interface. The proposed refined theoretical model allows s different states of the adsorbing molecules at the interface. The comparison between the model and experiment demonstrates that, for C₁₄EO₄, the assumption of s = 5 adsorption states provides a much better agreement than for s = 2, while for C₁₄EO₈, a number of s = 10 adsorption states allows an optimum data description.
