A pale yellow, semidrying oil obtained from the beans of the soya plants, Soja hispida, Soja japonica, or Phaseolus hispida. Originally native to Asia, the soybean is now cultivated throughout the world. Soybean oil contains the following fatty acids: palmitic (12-14%), oleic (25-26%), linoleic (53-57%), stearic (2%) and linolenic (3-8%). The oil dries slowly to form a soft, clear film. The film, however, remains tacky and darkens with age. Soybean oil has been used as an additive in alkyd-based industrial paints. It was also used in Fidelis Artist's Oil Colors. Commercially, soybean oil is used in margarine, shortening, vegetarian food products, paints, adhesives, fertilizers, linoleum, cloth sizing, insect sprays and fire extinguishers.
