The hydrophobic tail effect on the synergistic effect between DS -, water, and the C12E6 monolayer, ∆t∆C F cavity components (relevant for DS 0 ), as well as the electrostatic interaction component. There is still an effect due to the DS -head group within F (4) t,h,W,C (z) accounting for the collective effect between head, tail, the water, and the C 12 E 6 monolayer, which mostly captures orientational effects that point head towards the water, and tail towards the monolayer.
