The damping of oscillations is strongly affected by a presence of surface-active agents (surfactants, e.g. washing agents). We have studied effect of surfactants on the shape oscillations of a bubble, which is attached at a tip of a capillary. Experiments were repeated in aqueous solution of several surfactants (terpineol, SDS, Triton X-100, Triton X-45 and CTAB) at various concentrations. The oscillation frequency and damping time is studied and comparison of results for various surfactants is done.
