I'm wondering what other soapers put as their SF level? I've tried 20% pure CO soap(which I thought dissolved in the shower rather quickly), and 8% and 5%. I'm not really finding a a huge difference in terms of dryness or its ability to moisturize, though I do think there is some. My goal is to have a long lasting bar in the shower. Which is why I doubt I'd make 20% SF again. How do you decide your superfatting level? Thanks!
