Does vegetable glycerin made out of soy bean possess trace amounts of estrogen

Vegetable glycerin itself is a byproduct of the saponification process used to create soap or the transesterification process used to create biodiesel, and it is derived from fats and oils, including those from soybeans. However, vegetable glycerin is a simple sugar alcohol and does not inherently contain estrogen or any hormones. That said, soybeans do contain phytoestrogens, specifically isoflavones, which are plant compounds that can mimic estrogen in the body. If vegetable glycerin is derived from soybeans, it's theoretically possible that trace amounts of these phytoestrogens could be present, but the levels would likely be very low and not significant enough to have a noticeable effect. If you have concerns about phytoestrogens or soy-derived products, it's best to consult with a healthcare professional.
