Documented applications: Uses: The main use of simethicone as an excipient is as an antifoaming agent in pharmaceutical manufacturing processes ... ., A poly(dimethylsiloxane) which is a polymer of 200-350 units of dimethylsiloxane, along with added silica gel. It is used as an antiflatulent, surfactant, and ointment base., Antifoaming ingredient in cosmetics, Simethicone manufactured under the name of MED-340 is used in the production of anti-gas tablets, lubrication and bubble free application of topical preparations, anti-whitening properties in acne and other dermatological ointments, creams and lotions, as an antifoam in the manufacture of drug products made by microbial fermentations, listed in the INCI index for use in cosmetic and toiletry products., For more Uses (Complete) data for Simethicone (6 total), please visit the HSDB record page., Use Classification: Food Additives -> ANTICAKING_AGENT, ANTIFOAMING_AGENT -> JECFA Functional Classes, Food Additives -> ANTICAKING_AGENT, Cosmetics -> Skin conditioning, Emollient, Hair conditioning, Antifoaming, Industry Uses: Defoamer, Household Products: Information on 107 consumer products that contain Simethicone in the following categories is provided:, • Inside the Home, • Personal Care, Methods of Manufacturing: Silicone dioxide is initially rendered hydrophobic in one of a variety of proprietary processes specific to a particular manufacturer. It is then slowly mixed with the silicone fluids in a formulation. After mixing, the simethicone is milled to ensure uniformity., Formulations, Preparations: Antifoam A, Baros, Colicon, Endo-Paractol, Gas-X, Infacol, Lefax, Mylicon, Phasil, Phazyne, sab simplex, Silain., Table: Simethicone Combinations [Table#4658], Table: Simethicone Preparations [Table#4659], Simethicone is a mixture of fully methylated linear siloxane polymers containing repeating units of polydimethylsiloxane, stabilized with trimethylsiloxy end-blocking units, and silicon dioxide. Simethicone contains 90.5-99% of polydimethylsiloxane and 4-7% silicon dioxide., U.S. Production: 2023: <50, 000 lb, 2022: <50, 2021: <50, 2020: <50, General Manufacturing Information: Not Known or Reasonably Ascertainable, Dimethecone mixed with silicon dioxide is known as simethicone, The defoaming power of simethicone, when assoc with antacid, is more pronounced in suspension than in tablets. Incorporation of lactose in tablets enhances the defoaming efficiency. Antiflatulent-antispasmodic digestive tablets (simethicone, belladonna ext, pepsin, pancreatin, and dehydrocholic acid) achieve a mild decrease in their defoaming efficiency when stored for 360 days at 25 °C. Pepsin shows a reduction in its activity in tablets with simethicone while pancreatin achieves relatively greater stability with simethicone. The stability of total alkaloid content of belladonna is also improved with simethicone., Average number of dimethylsiloxane units is 200 to 350., NuSil currently manufactures a simethicone product line consisting of the MED-340 Simethicone USP (100%), MED-341 Simethicone Emulsion USP (30%), and the MED-342 Simethicone GS (30% granular solid). The MED-340 and MED-341 are USP monographed products while the MED-342 is a mixture of simethicone USP and a maltodextrin substrate..
