Akasil® Antifoam FD 20

Akasil® Antifoam FD 20 is medium strength silicone antifoam emulsion. This highly effective, water soluble product is specially formulated for use in processing waters where food considerations apply.

Part of the market-leading Akasil® range of antifoam solutions, we supply and distribute this product in bulk 25L drums to meet any requirement.



This product helps to maintain stable water conditions for optimal efficiency in environments where special considerations may apply, such as food processing.

Sitting in between Akasil® FD 10 and FD 30, FD 20 is suited to environments where a medium level of antifoam activity may be desired. This can include:

- Beers, lagers and breweries: fermenting, boiling, centrifuging and yeast transfer
- Alcohol and spirits: bio-culture forming, fermentation
- Vinegars and condiments: fermentation, bottling
- Fruits and vegetable washing and processing
- Meat processing
- Slaughterhouses: entry of proteins into sewage works
- Dairy applications
- Brine applications
- Sugars, jams and syrups applications


Akasil® Antifoam FD 20: high-performance, food-approved silicone antifoam agent for food processing

A white liquid with 20% silicone content, this product is a non-ionic emulsion specially formulated for foam-susceptible environments where special considerations apply, such as food processing (but not directly for use in food production).

Stable over a range of temperatures and requiring only mild agitation, FD 20 disperses easily in both hot and cold aqueous systems for optimum efficiency and safety. In food production, this product is a process aid, not an ingredient.

This product holds European H1 and Kosher certification, meeting the highest level of regulatory approval for use as foodstuff process-aids.

Recommendations for use

We recommend pre-diluting for the best end results, with a ratio of 1 : 4 ratio of Akasil® Antifoam FD 20 : cool soft or deionised water. For optimal results, the antifoam mixture should be used within 12 hours of having been diluted. The product should be added to lines before use. As a rule, between 0.01 and 0.5g/L of antifoam is sufficient.
