We propose a general method to analytically solve transport equations as well as the bubble wall profile during a cosmic phase transition. For the bubble wall profile we approximately solve the general one dimensional problem and derive a perturbative series of corrections to this ansatz and prove convergence. We then present general analytic solutions for coupled transport equations that govern the behavior of particle number densities during a phase transition. Finally we derive a perturbative series that relaxes the usual approximation that inactivates VEV dependent relaxation and CP violating source terms at the bubble wall and through the symmetric phase.
