Soy vs. Paraffin

Paraffin wax is a heavy hydrocarbon that comes from crude oil. Paraffin waxes are produced by refining or separating the waxes out of crude mineral oils. Obtained from the ground, crude oil is a compositionally varied product, consisting of a mixture of hydrocarbons. Another name for crude oil is fossil fuel. Crude oil is transported to refineries where it is refined into finished products by complex processes. One of the many products derived from refining is lubricating oil. It is from the lube oil refining process that petroleum waxes are derived. There are three general categories of petroleum wax that are obtained from lube oil refining. They include paraffin, microcrystalline and petrolatum. Paraffin waxes are derived from the light lubricating oil distillates. Paraffin waxes contain predominantly straight-chain hydrocarbons with an average chain length of 20 to 30 carbon atoms.

Soy wax, on the other hand is made from vegetable matter. 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 then extracted from the flakes and hydrogenated. The hydrogenation process converts some of the fatty acids in the oil from unsaturated to saturated. This process dramatically 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 soybeans, primarily in Illinois, Iowa, and Indiana.

While petroleum based paraffin wax is a limited resource, soy wax is a renewable resource that is limited only by how many soybeans we can grow. It is also beneficial to farmers who sell soybean crops, as well as lasting almost twice as long as paraffin wax.
