I make goat milk soap and am trying to understand superfat. I think I finally got it in my head now but want to confirm... So if I am making a batch of soap with 10oz olive oil, 5% superfat, then I would mix the lye with 9.5 oz of olive oil and then the superfat would be 0.5 oz which I could either add before or after trace. Is that correct? So I just multiply the amount of oils by the percentage I want the superfat to be? So if I wanted 10% superfat I would multiple it by 0.1?
