  Well-posedness is proved for the stochastic viscous Cahn-Hilliard equation
with homogeneous Neumann boundary conditions and Wiener multiplicative noise.
The double-well potential is allowed to have any growth at infinity (in
particular, also super-polynomial) provided that it is everywhere defined on
the real line. A vanishing viscosity argument is carried out and the
convergence of the solutions to the ones of the pure Cahn-Hilliard equation is
shown. Some refined regularity results are also deduced for both the viscous
and the non-viscous case.
