We calculate the CMC of the surfactants (following Anderson et al. ) to validate our model. For SLSar we obtain a calculated CMC of ≈ 10-14 mM, versus an experimental value of ≈ 12-14 mM. Likewise, for CAPB we find a CMC of ≈ 2-4 mM, versus an experimental value ≈ 3 mM. The length scale in the DPD model is set from the water bead 'mapping number' N m = 2, where N m is the number of water molecules per water bead. Following well established protocols we set the cut off distance (r c ) for the DPD soft repulsive interaction between water beads as the unit of distance. We set the dimensionless water bead number density representing pure water to ρr 3 c = 3. The DPD conservative force repulsion amplitude is set to A ij = 25. Using Avogadro's constant N A and the molar volume of water V w ≈ 18 L mol -1 , the volume occupied by one mole of DPD 'volume elements' is
