I am making soap with Olive Oil, Coconut Oil, Water, Lye and Essential oil. Once I have everything mixed together and have reached a pudding consistency, I'm adding the essential oil right at the end, then I do a final mix and then pour into molds. The result is nice soap but I can never smell the essential oil at all. I've tried various essential oils, various grades of essential oils from cheap to expensive, and various amounts from a little to a bunch - yet it makes no difference, I still cannot smell them at all once their put into the mixture. I figured I must be doing something wrong. Please help.
