Simethicone 30% (IP or USP grade) is a general purpose silicone based defoamer emulsion used for anti-gas and anti-flatulent formulations. Our high quality product ensures that the silicone oil used has low volatile content (less than 1%). Simethicone 30% is effective at low concentrations of just 1-50 ppm. It is easily diluted by cold water with gentle stirring. We can supply both the IP and USP grade emulsions in packing of 50 kg (domestic only), 200 kg and 1000 kg.
