Simethicone is a surfactant that can alter the surface tension of bubbles in chyme and mucus, causing them to break down. The released gases are absorbed by the intestinal wall, thereby further purifying the mucus in the intestinal cavity and providing a clearer view during intestinal endoscopy.

Liposome silicone oil is a type of surfactant. It can alter the surface tension of bubbles in food residue and mucus, and cause them to disintegrate. The contained gases are released and absorbed by the intestinal wall, thereby further purifying the mucus in the intestinal cavity and making the intestinal endoscopy view clearer.
