(I) Growth inhibition zones of Staphylococcus aureus ATCC (6358) and E. coli ATCC (25,923) caused by SAH, compared to the positive control (Doxycycline) and the negative control (DMSO), (II) Pseudo-ternary phase diagram of oils (Maisine and Capryol 90, in ratio 1:1), Surfactant/CoSurfactant mixtures (Smix) (Cremophore EL/Transcutol, in ratio 2:1), and water. The defined percentages of the oils (5–25%), water (25–45%), and the Smix (50–70%) are represented by the black triangle, and (III) 3D surface plots demonstrating the effect of the independent variables; the oil (X1), the water (X2), and the Smix (X3) on (a) Droplet size in nm (DS), (b) Polydispersity index (PDI), (c) % Transmittance, and (d) The cumulative percent of SAH released in 8 h (Q8).
