Soybean oil is a natural vegetable oil extracted from the seeds of the soybean plant (Glycine max). It is composed primarily of triglycerides formed from unsaturated fatty acids such as linoleic, oleic, and linolenic acids. Widely used across industries, soybean oil serves as a key raw material in food production, cosmetics, pharmaceuticals, and industrial formulations. In the chemical sector, it is valued for its role in the manufacture of alkyd resins, biodiesel, and lubricants. Its bio-based origin and biodegradability make it an attractive alternative to petroleum-derived ingredients in coatings, inks, and plastic additives. Soybean oil is classified as a natural product and oleochemical, and while it is not a plasticizer in its raw form, it is often chemically modified, such as through epoxidation, to serve as a functional additive in polymer applications.
