I just caught this thread and have to respond. You can try all of the above mentioned strategies, but if you are truly sensitive to coconut oil, you'll want to stop using it altogether. I can tell if there is 5% of co in my soap, because my skin raises hell with me. I sub co with pko at around 20%. If I use more than 20% pko, it starts to feel like co. If you want more bubbles than you can get with 20% pko, then add 10% castor oil, which also helps with moisturizing. I always add at least 10% of an oil with linoleic acid such as sunflower oil, grapeseed oil, or rice bran oil. Actually, I've discovered that rice bran oil is a good sub for olive oil as a base oil in that it seems gentler on my extremely sensitive skin. Hope this helps.
