Dow Corning Q7-2243 LVA
Mixture of a low-volatile polydimethylsiloxane fluid.
Dow Corning Q7-2243 LVA, Simethicone USP, is a specially formulated low volatile silicone antifoam designed for use in various medical and pharmaceutical applications requiring foam suppression or inhibition.
Dow Corning Q7-2243 LVA, Simethicone USP, is formulated and manufactured so that the quantity of volatile, low-molecular-weight silicone species is minimal.
This low volatility (1 percent maximum) is especially advantageous in the manufacture of antiflatulent or antiflatulent/antacid tablets and other products where processing conditions, such as drying by high surface area exposure at elevated temperatures, will result in loss of volatile silicone species and subsequent low assay results for silicone fluid.
