  We analyze the nMSSM with CP violation in the singlet sector. We study the
static and dynamical properties of the electroweak phase transition. We
conclude that electroweak baryogenesis in this model is generic in the sense
that if the present limits on the mass spectrum are applied, no severe
additional tuning is required to obtain a strong first-order phase transition
and to generate a sufficient baryon asymmetry. For this we determine the shape
of the nucleating bubbles, including the profiles of CP-violating phases. The
baryon asymmetry is calculated using the advanced transport theory to first and
second order in gradient expansion presented recently. Still, first and second
generation sfermions must be heavy to avoid large electric dipole moments.
