I know that shea butter is used in foods in some parts of the world. I have not actually seen it for sale in food stores, so have no experience using it in cooking. I have never considered using the product I buy for soap, but I don't know that I wouldn't if the whim hit me.
For sure I wouldn't use Castor Oil, Red Turkey Oil (Sulfated Castor) or Fractionated CO in cooking. Other than that, I'd probably be willing to use any of the others I normally buy for soap as long as I didn't already put ROE into the container. Lard is another I won't use, but not because it's a soaping fat, but because it come from a dead animal (personal choice.) However, to be honest regarding oils in cooking, I'm a snob and won't use most oils. I like Walnut oil and Olive oil the best for cooking. I used to like CO for cooking certain things, but lost my taste for it after a while.
