No reason to buy the pricey stuff for soap. The Sap value and fatty acid profile is the same. The lye interacts with it just the same. You don't eat soap, so why buy raw or virgin?
I agree with Earlene. Unless you are selling and your brand focuses on organic ingredients, there is no reason to pay extra for organic oils. If you have concerns about personal exposure to unhealthy substances, my understanding is that coconuts aren't GMO and aren't sprayed with pesticides. That leaves only the refining process as a potential concern, which you should research to see if that is of importance to you.
