A study has been made of the roles of the alcohol and electrolyte in changing the viscosity and electrical conductivity of single-phase microemulsions from a petroleum sulfonate, an aliphatic alcohol, decane, and water (or an aqueous electrolyte solution). As the alcohol concentration is increased, the system viscosity passes through a maximum, the position of which is approximately the same for different alcohols. With increasing hydrophilicity of the alcohol or decreasing concentration of the electrolyte, the absolute magnitude of the viscosity maximum increases, with a simultaneous decrease in the width of the single-phase region. It has been found that the electrical conductivity increases sharply, by 2.5 orders of magnitude, when the concentration of alcohol is increased above that corresponding to the optimal HLB of the system.
