I parachuted into this group from a group of long ago who still believed that luxury oils should be added at the very end so as to save them from the initial ravages of the lye. Now I read that it doesn't matter when you add those oils because the lye is going to have its way with them no matter what you do to protect them. For my re-introduction to soap making a week and a half ago, I couldn't bring myself to do it the new way. The luxury oils went in at light trace. I've made two more batches since then and, due to logistical reasons, it was more convenient to add them with the base oils, so I did it. (I felt guilty!) I am curious, despite all the modern day advice, how many of you still add your luxury oils at the last minute?
