Cosmetic Silicones Manufacturers introduces the precautions for the use of simethicone: Simethicone is a safe defoaming agent in the extraction and reflux process of traditional Chinese medicine and biological fermentation. It has low surface tension and is insoluble in water, animal and vegetable oils and high-boiling mineral oils. It has good chemical stability and non-toxicity. It can be used as a defoamer. The agent has been widely used in petroleum, chemical, medical, pharmaceutical, food processing, textile, printing and dyeing, papermaking and other industries. As long as 10-100PPM silicone oil is added, it has a good defoaming effect. In the process of extraction and reflux of traditional Chinese medicine and biological fermentation, a large number of bubbles are often produced, resulting in spills or explosions. The common method of use is to add a small amount of defoamer. The surface tension of the defoamer is small, which can change the surface tension of the bubbles and make it Rupture, can eliminate the gas stored in the foam during the reflux extraction and biological fermentation of traditional Chinese medicine. Common defoamers include ether, simethicone or others; the components of ether and some composite defoamers have physiological activity and are safe Sex is not recognized. Simethicone is the only defoamer approved by the drug regulatory authority. The amount of simethicone is about 10 ml per cubic extract (fermentation broth), which has a significant defoaming effect. https://www.silways.com
