Dimethylpolysiloxane

International Numbering System (INS) for Food Additives: 900
 

Dimethylpolysiloxane (DMPS) is an interesting case as a food excipient. Here's why:

Limited Use in Food:

• DMPS isn't a common food additive and generally isn't recognized as safe (GRAS) by the FDA for use in food in the United States. There's limited information available about its specific functions or applications in direct food processing.

Possible Antifoaming Agent:

• Some sources suggest it might have antifoaming properties. In theory, this could be useful in certain food applications to prevent excessive foaming during processing or even control foaming in the final product. However, there's a lack of definitive information about its use for this purpose in food.

More Common Applications:

• DMPS finds more frequent use in industrial applications as an antifoaming agent, defoamer, or lubricant due to its properties:
  • Antif foaming/Defoaming: It can reduce or prevent the formation of foam in industrial processes like silicone mold release or during manufacturing processes that involve agitation or mixing.
  • Lubricant: It can act as a lubricant due to its slippery nature, reducing friction in various industrial applications.

Safety Considerations:

• While not widely used in food, safety studies suggest that DMPS may be relatively non-toxic at low levels. However, due to the lack of established applications and safety data in food processing, it's not generally recommended for food use.

Conclusion:

Dimethylpolysiloxane is not a common food excipient and its use in food is not approved by the FDA in the US. Its primary applications are in industrial settings like a defoaming agent or lubricant. If you encounter DMPS listed in a food product, it would be uncommon and advisable to research further to understand its specific purpose and safety in that context.
