When a liquid containing surface active molecules advances on a hydrophilic solid surface, specific instabilities are observed. They are due to the diffusion of the surface active molecules which adsorb on the surface, increasing the contact angle. These instabilities appear as waves travelling along the contact line and are visible only in a limited range of liquid edge velocities.
