Figure 2

Response surface graphs showing effect of binary mixture concentration and surfactant concentration. (a) Droplet size: concentration of binary mixture increased with an increase in droplet size, while concentration of surfactant increased with an increase in droplet size. (b) PDI: concentration of binary mixture decreased with an increase in PDI, while with an increase in concentration of surfactant, PDI increased. (c) % EE: concentration of binary mixture increased with an increase in % EE, while the concentration of surfactant also increased with an increase in % EE.
