The effects of temperature and of divalent ion concentration on the structure of aqueous surfactant solutions have been determined. As temperature increases, the salinity range...

Two model surfactant systems, one based on Texas 1 and the other on sodium dodecyl sulfate, were developed to give ultralow interfacial tensions and middle phase microemulsions...

The effects of temperature and of divalent ion concentration on the structure of aqueous surfactant solutions have been determined. As temperature increases, the salinity range...

The polarizing microscope was used to study the structure of aqueous solutions of petroleum sulfonates in the composition range planned for injection. All the surfactants...
