Susie, thank you for your recipe! I want to try it and add some EO for fragrance. When and how can I add it? I need to use emulsifier for the EO?
I add EOs at the end of dilution, when the soap is still quite warm. I can stick a bare finger in it, but I would not be comfortable leaving it there long. I do not use emulsifiers, as I tend to stay away from problematic scents. If you do get separation, you will need an emulsifier. I believe IrishLass uses PS80. I think it is equal parts PS80 to EO, but I could be wrong.
