Optimization of emulsions.
Synopsis The optimization of three emulsions with predetermined components was performed by the aid of experimental design. Three different surfactants were compared: the salts of hexadecylhydrogenphosphate with diethanolamine, lysine and arginine respectively. Optimized microemulsions showed quite high stabilities towards centrifugation (30-60 min at 7000 rpm). The results showed that the counter-ion can affect the composition and stability of an emulsion.
