This is made by Birko and is a food grade canola product. It is suppose to break down into a yeast nutrient.
I now see where Brewers should not use silicone-containing antifoam for unfiltered beers. The FDA allows active silicone to be used up to 10 parts-per-million (ppm) but stipulates that the silicone must be removed prior to packaging by either filtration or centrifugation. In the case of unfiltered beers, use a food grade, non-silicone antifoam.
I have been using Fermcap but would be interested if anyone has experience with this product.
