N2 - W/O/W multiple emulsions with ethylene oxide free emulsifiers, compatible with the skin, were prepared. They were fresh and easy to spread on the skin. The emulsion showed a shear thinning flux. Their multiplicity was confirmed with optical microscope analysis. FeSO4 and K3Fe(CN)6, when introduced separately in the inner and outer aqueous phases of the emulsions, did not give coloration, but when introduced together in the same aqueous phase, give a blue color due to their reaction. This experiment confirmed the multiplicity of these systems. The external aqueous phase of the emulsions was confirmed by Brilliant Blue up take from one of the multiple emulsions prepared higher than that from its W/O primary emulsion. The stability of the systems was confirmed by tests of breaking to centrifuge, of storage at 40°C and by freeze-thaw cycles.
