Mechanism of antifoaming action of simethicone

The mechanism of the foam-inhibiting action of simethicone, mainly used against flatulence, has been studied. The mechanism of these actions may be described as the liquid drainage followed by bridging of the liquid film by polydimethylsiloxane droplets, helped by hydrophobic silica particles also present in the antifoaming agent, leading to the rupture of the film surface and air escape.
