Optimum Microemulsions Formulated with Propoxylated Guerbet Alcohol and Propoxylated Tridecyl Alcohol Sodium Sulfates

This is a study of the phase behavior of Propoxylated Guerbet alcohol sodium sulfates C14EX(PO) and C16EX(PO) and Propoxylated tridecyl alcohol sodium sulfates C13(PO) using oil phase composition, water salinity and composition, temperature and propylene oxide number, PON, as variables, show the ability of these surfactants to generate optimum middle phase microemulsions. Optima were found for a wide range of system conditions, e.g. 2% to 16% electrolyte (including Ca⁺⁺), 30°C to 80°C and octane to hexadecane for the oil phase.
