Soybean Oil is the first ingredient listed in Lisa's Hair Elixir.
It contains about 60% polyunsaturated fatty acids and is a good source of Vitamin E, used frequently in soaps and bath oils. The oil is extracted, consisting of emollient properties such as oleic, linolenic and saturated acids. Ancient traditions cultivated soybeans for its protein, oil, and lecithin content – believed to be a superior moisturizing agent that helps soften skin.
Soybean oil has a relatively high proportion, 7–10%, of oxidation prone linolenic acid, which is an undesirable property for continuous service, such as in a restaurant. Soybean oil also contains natural antioxidants which remain in the oil even after extraction. These antioxidants help to prevent the oxidative rancidity.
