Phase maps were determined in the system water, sodium dodocyl sulfate, pentanol and a commercial mineral oil (Drakeol® 7) and the dimensions in the lamellar liquid crystal were determined using low angle x-ray diffraction. The mineral oil gave a strong reduction in the water-in-oil microemulsion region solubilization capacity for water when combined with the cosurfactant in a 1/1 weight ratio. For less oil/cosurfactant ratios a large oil-in-water microemulsion region was observed The mineral oil added to the liquid crystal in the system strongly reduced the water penetration into the hydrocarbon chain region and enhanced the disorder of the hydrocarbon chains in the structure.
