Small-angle neutron (SANS) and quasielastic light scattering (QLS) techniques have been used to study a family of microemulsions formed in a salinity scan with sodium 4-(1’-heptylnonyl benzene sulfonate) (SHBS), iso-butanol, NaCl brines and dodecane. The growth of microemulsion “droplets” and the evolution of bicontinuous structures have been examined, and a model of the dynamics of microemulsions that contain comparable amounts of both water and oil is reviewed. SANS measurements reveal the decrease in surfactant head group area from ca.200 Å2 to 125 Å2 as the salinity increases and the composition varies from oil-in-water to water-in-oil.
