What is the chemical process used in creating  soy candles?
assistant
The process used in creating soy candles is the process of hydrogenation, a chemical process by which liquid vegetable oil (such as soybean oil) is converted into a semi-solid or solid form of fat. This is done by adding hydrogen atoms to the vegetable oil molecule and changing its chemical structure. The results of hydrogenation are a higher melting point, a longer shelf-life, and a milder odor.
