  "abstract": "We investigate the changes in 3:1 mixed SDS/CAPB surfactant solutions (at the 400 mM scale) as adding alkali/halide salts up to a concentration of 2.5M using coarse grained molecular dynamics simulations coupled with a Hamiltonian Replica Exchange scheme and by accounting for long range electrostatic effects. As adding salt, micelle properties (size, morphology, degree of neutralization, equilibrium between surfactant chains within 'end cap' and 'cylindrical' micellar subdomains) as well as surfactant solution shear viscosities all obey a linear regime until a salt concentration of about 1M.Then they obey a new regime in which they all fastly and non linearly diverge, in line with available experimental evidences regarding similar mixed anionic/zwitterrionic surfactant solutions. Interestingly the transition between those two regimes can be rationalized by considering an equilibrium between only SDS chains in 'end cap' and 'cylindrical' micelle domains (according to the pseudo-phase thermodynamic framework), with CAPB chains taken into account implicitly. Our simulation protocol appears to be a promising tool to investigate the effects of co-surfactant and/or hydrophobic (fragrance) molecules on surfactant solutions.",
