Silicone Antifoam
Liveo™ Q7-2243 LVA, Simethicone USP is a specially formulated low volatile silicone antifoarn designed for use in
various medical and pharmaceutical applications requiring foam suppression or inhibition.
Liveo™ 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.
Packaging :
Liveo™ Q7-2243 LVA, Simethicone USP is available in 18 and 200 kg containers, net weight.

Additional Information
How to use Storage:
Some settling may occur during storage of Liveo™ Q7-2243 LVA, Simethicone
USP. Therefore, containers should be thoroughly mixed prior to use or testing.
How to Use:
Process Defoaming: In general, concentrations of 1 to 50 parts per million
(ppm) are sufficient to suppress foaming in most systems. It is suggested that a
concentration within this range be used initially. Adjustments in concentration
may be desirable to detennine the appropriate level to use for any particular
process or product.
The height to which a foam will rise can be limited by applying Liveo™ Q7-2243
LVA, Simethicone USP to processing equipment. For example, the defoamer is
often wiped on nozzles of bottle-filling machines to knock down foam as it
rises in the neck of the bottle. Similarly, if applied to the rim of a processing
container, foam overflow can be prevented.
