Summary Aqueous solutions of two petroleum sulfonate surfactants, a pure sulfonate surfactant and one mixed with an ethoxylated sulfate surfactant, were studied with polarizing microscopy, polarized light screening (PLS), and viscometry. The same seq

The transition from liquid crystalline to microemulsion phases has been investigated by adding oil to surfactant—alcohol—brine mixtures in two systems containing anionic surfactants. At high salinities where the surfactant is preferentially solub

Lamellar liquid crystalline phases in equilibrium with excess oil have been discovered at water-to-oil ratios near unity and low salinities in systems containing petroleum or pure sulfonates and long-chain hydrocarbons. These liquid crystals have low

Lamellar liquid-crystalline phases containing only about 5–10% surfactant by weight and having relatively low viscosities have been found to exist in Under suitable conditions, dilute liquid crystals can coexist with pure hydrocarbons. The tension

The phase behavior of systems containing the pure anionic surfactant Aerosol OT or sodium bis(2-ethylhexyl) sulfosuccinate was studied as a function of salt concentration, surfactant concentration, alkane carbon number, and water-to-oil ratio. Since
