Food Grade Silicone Defoamers

ACCESS Technologies line of food-grade antifoam agents are water-based silicone emulsions (as polydimethylsiloxane) designed to control foam in aqueous food processing applications.

General Details

About Silicone Defoamers

The functional properties developed especially for these antifoams to eliminate and prevent excessive foam include: quick dispersibility, slight insolubility, relative stability, and a high degree of spreadability in the foaming system. The primary active ingredient, polydimethylsiloxane, is an FDA-approved liquid silicone polymer with the following structure:

n represents repeating dimethylsiloxane units

ACCESS Technologies silicone antifoam agents utilize only food-grade, nonionic emulsifiers and contain only ingredients that are recognized by qualified experts as safe in food products according to the Code of Federal Regulations, Title 21, Part 173.340(a)(2).  They may therefore be used as direct food additives in many foods, with an allowable final concentration present in the food at levels ranging from 33 to 333 parts per million (mg/L), depending upon the silicone content of the antifoam. In addition, silicone antifoam agents are also widely used as indirect food additives for the manufacture of articles or components of articles intended for use in producing, manufacturing, packing, processing, preparing, treating, packaging, transporting, or holding food; and are approved for the manufacture of paper and paperboard per 21 CFR 176.170, 176.180, and 176.210. As processing aids, silicone antifoam agents are considered ‘secondary direct food additives’ and impart no flavor, odor, or functional attributes to the food. They are also exempt from ingredient and nutritional labeling requirements. Please consult the Code of Federal Regulations for further clarification on antifoam usage in your particular food-grade application.
