These products are treated to have their natural scent, color, or texture removed for esthetic purpose. Each refinery has its own unique method to refine a raw material. The refining process may include the use of high temperatures and a vacuum system along with bleaching earth/clays to deodorize the oils. The benefit of using refined oils in cosmetics is that the final product will not be tainted by the oils and colors of the raw materials. They are also heat-stable and thus suitable for combining with ingredients that require heat in the production stage.
