Question

I would like to confirm the composition of the product Food Anti-Foaming / Defoamer (Powder, Silicone Based) (Product ID: 31008). Is this product chemically equivalent to Silicon Dioxide (INS 551), as defined by the Ministry of Public Health announcement?

Answer

The product "Food Anti-Foaming / Defoamer (Powder, Silicone Based)" (ID: 31008) is not Silicon Dioxide (INS 551) alone, but a functional blend.

Its composition is:

  • Silica (which is Silicon Dioxide, INS 551): 85.0% (This acts as the carrier powder).
  • POLYDIMETHYLSILOXANE (a silicone defoamer): 15.0% (This is the active anti-foaming agent).

Therefore, while the product contains a high percentage of Silicon Dioxide (INS 551), it is a mixture designed for anti-foaming, with the active silicone component dispersed on the Silica powder.
