Soy wax is a vegetable wax made from the oil of soybeans. After harvesting, the beans are cleaned, cracked, de-hulled, and rolled into flakes. The oil is extracted from the flakes and then hydrogenated.
The hydrogenation process converts fatty acids in the oil from unsaturated to saturated. This process alters the melting point of the oil, making it a solid at room temperature. The leftover bean husks are commonly used as animal feed.
The U.S. grows the vast majority of the world’s soy beans – primarily in Illinois, Iowa, and Indiana.
