Cottonseed oil is cooking oil from the seeds of cotton plants of various species, that are grown for cotton fiber, animal feed, and oil.
Cotton seed has a similar structure to other oilseeds such as sunflower seed, having an oil-bearing kernel surrounded by a hard outer hull; in processing, the oil is extracted from the kernel. Cottonseed oil is used for salad oil, mayonnaise, salad dressing, and similar products because of its flavor stability.
