Observation of a Vanishing Miscibility Loop in the Phase Diagram of Solutions of Mixed Nonionic Ionic Amphiphile / L.De Salvo Souza, M.Corti, L.Cantu', V.Degiorgio. - In: CHEMICAL PHYSICS LETTERS. - ISSN 0009-2614. - 131:1-2(1986), pp. 160-164.
Abstract:
Aqueous solutions of dodecyl hexaoxyethylene ether (the non-ionic amphiphile C12E6) with added sodium dodecyl sulfate (SDS) show a closed solubility loop which shrinks progressively as the SDS/C12E6 molar ratio r increases and disappears when r is larger than 0.013. The results are explained by noting that the interaction potential between two mixed micelles contains, besides an attractive part typical of non-ionic micelles, an electrostatic repulsive contribution.
