How did cottonseed and oleomargarine change the demand for cotton?

short response

The introduction of cottonseed oil and the invention of oleomargarine changed the demand for cotton by creating additional uses for cotton crops. Cottonseed oil became a valuable commodity used in cooking, so its increased demand led to a higher demand for cotton to produce more cottonseed. Similarly, oleomargarine, made partially from cottonseed oil, became a substitute for butter. As oleomargarine gained popularity as a cheaper alternative, the demand for cottonseed oil to produce it also increased, resulting in a higher demand for cotton.
