Let us now explain how we carried out the DPD-MD simulations. To begin with, a coarse grained DPD simulation was carried out for the surfactant molecules in the organic and water phases individually . In order to carry out these simulations, all the particles were placed at random positions within the rectangular box of 100x100x100 nm 3 and using a grant size as 1 nm 3 . These simulations allowed us to estimate the repulsion parameters (Table ) between components.
