摘要: This article is the first part of a two-part study that exemplifies how to treat solubilization water in multicomponent surfactant-based systems. In particular, it aims at clarifying role cosurfactants these The judicious selection components such systems maximize occasionally thought be dictated by chain length compatibility principle, which may expressed quantitatively BSO (Bansal, Shah, O'Connell) equation. Here we demonstrate some limitations For example, our best model system, C12(EO)8/dodecane+pentanol=1:1 (by weight)/water 27+/-0.2 degrees C, equation predicts no alcohol needed for maximum solubilization, contrary experimental findings. We discuss optimize alcohol/oil weight ratio stabilizing four-component microemulsions. C12(EO)8 or C(18:1)(EO)10/pentanol/dodecane/water, this optimal 1:1. also highlight difference between effect normal alcohols on solubilization-which passes via maximum-and their percolation processes and structured changes proteins, depends solely upon hydrophobicity. investigation branching phase behavior utilization an extended form geometrical factor F(b) suggested. meaning elucidated comparing with topological indices.
