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™ Medical Antifoam A Compound 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.

Tableting

Medical Antifoam A Compound may be used in certain pharmaceutical applications by first applying it uniformly to an excipient such as sugar or starch. This mixture is then added directly to the batch according to normal processing procedures.
