The solution behavior in water of a binary system consisting of monoglyceryl ether (GE) and diglyceryl ether (DGE-OMe) was studied by observing their ternary phase diagrams. Both GE and DGE-OMe are surfactants with less solubility in water, and form lyotropic liquid crystals even when present at low concentrations.
A reversed hexagonal liquid crystal formed in the ternary system (φ=0.2) was found thermodynamically more stable than that in the GE/water system (φ=-0.2). X-ray measurements along with the results of an ESR spectroscopic study on the structures of reversed liquid crystals indicated these thermodynamic changes in liquid crystals to be due to the structural changes such as d-spacings caused by the interaction of the hydrophilic portions of the mixed two surfactants.
