Diagram showing the existing relationship between the occlusivity of the emulsion water/perhydrosqualen/surfactant: 80/15/5 to different HLB's and the importance of the oily isotropic phase in the ternary diagrams obtained with the same constituents for each of the HLB's. The importance of the oily isotropic phase is expressed in % in relation to the total surface for the diagram (see figure 6). --•--•--•-- ester surfactant (Montane 80©-Montanox 80 ©) --I--I--I-- ether surfactant (Simulso192©-Simulso196 ©) 60 40 • 20 ß • 60 40 20 15 10 o• 10 I I I I [ / I I I I I 4,5 6,5 8,5 10,5 12,5 15 H.L.B.
