8050-81-5 - Uses and synthesis methods
overview
simethicone is a stable surfactant, that is, polydimethylsiloxane, which can change the surface tension of bubbles in chyme and mucus in the digestive tract, and decompose it. The released gas can be absorbed by the intestinal wall or discharged through intestinal peristalsis.
pharmacological action
simethicone is a stable surfactant, that is, polydimethylsiloxane, which can change the surface tension of bubbles in chyme and mucus in the digestive tract, and decompose it. The released gas can be absorbed by the intestinal wall or discharged through intestinal peristalsis. In China, dimethicone or silica is often used as defoaming agent alone, but the effect is weak. The combination of the two can enhance the defoaming effect. 9.4mg of dimethicone and 0.6mg of silica can achieve the effect of 1000mg of dimethicone. As a complex of dimethicone and silica, the pharmacological effects of simethicone are far better than those of dimethicone or silica. Simethicone is a pharmacological and physiological inert substance. Subacute toxicity experiments in rats show that simethicone has no toxic effect.
production method
The product is obtained by polycondensation of high-purity dimethyldichlorosilane after hydrolysis.
