[Emulsion systems. I. Comparison of different formulation methods]

This paper examines different technics of emulsifying systems formulation: those using the research of HLBc and those using the phase diagram. The comparison of these two methods of formulation permits us to describe one method looking for the HLBc of each proportions of the phase diagram. So a volume is determined allowing to choose more securely the surfactants proportions and also to end on surer formulation.
