Brij surfactants) (Fig. 18). Additionally, LLC phases of commercially available
ionic surfactants such as metal salts of alkylsulfonic and alkylcarboxylic acids
[e.g., dioctyl sodium sulfosuccinate (aka, Aerosol OT)] and long-chain am-
monium salts have also been explored (Fig. 19). Some of these surfactants are
even U.S. Food and Drug Administration (FDA)-approved because of their
prior utility in other food or medication-related formulations.
