Using the effective Lagrangian approach, we develope the trilinear contributions originated in the dimension-six electroweak invariants O-tilde{sub W} = (1/3){epsilon}{sub ijk}W{sup i{mu}}{sub v}W{sup jv}{sub {lambda}}W{sup k{lambda}}{sub {mu}} and O-tilde{sub WB} = (1/2)B-tilde{sub {alpha}}{sub {beta}}W{sup c{alpha}}{sup {beta}}{phi}{sup {dagger}}{tau}{sup c}{phi}, and then we insert the corresponding vertices in a one-loop ttV diagram, with V off-shell, generating the structure of the electric dipole moment. Using a nonlinear gauge, we prove that the results are gauge independent. Finally, we present the analytic expressions for the electric dipole form factors originated in each invariant introduced.
