Hi all! I'm going to try shaving soap this weekend. I read a lot of the giant thread and hopefully have a decent recipe on my hands. I don't have any butters, so I'm planning on using avocado oil for the superfat. So I'd withhold 25g of AO from the 50g total, right? The glycerin (15%) is added post-zap along with the superfat and fragrance correct? And it doesn't factor into the oil weight?
