Foam is created when gas is dispersed into a continuous liquid phase and remains stabilized within the dispersi-on.
In pharmaceutical processes it is essential to keep the formation of foam under control. The presence of foam can cause serious problems during production. Excessive foaming leads to reduced equipment and container capacity and increased processing time. Foam may even negatively influence the quality of the final product (e.g. the surface of tablets).
In medical applications such as dialysis, where human blood is purified and redirected into the human body, the prevention of foam is an essential consideration.
In the ‘human system’ the formation of foam can also cause unpleasant gastrointestinal effects like bloating and stomachache.
With regard to the pharmaceutical industry, it is clear that in many applications a fast and effective antifoaming agent is needed to prevent uncontrolled foaming and to maintain smooth and efficient processes.
Biesterfeld Spezialchemie GmbH offers highly effective and versatile defoamers which can be used as supplied or further diluted with water. Typical applications are foam suppression and inhibition in fermentation, manufac-turing and filling processes. We also offer antifoams for critical medical applications, which are used as APIs in antiflatulents for solid or liquid dosage forms.
