How do you add Bentonite clay into a shaving soap recipe? I tried once on my first batch and I think I added it to my lye water. I tested a week later and it gave me mild lye burns on my wrist.. I'm assuming the lye absorbed into the clay and the lye soaked clay when lathered on my hands got caught in the creases on the top part of my wrist and well, burned me a bit.. I noticed even after i rinsed the foam off and my hands dry, there was a white powdery looking residue on my wrist where the foam was. The residue stopped where my lather stopped, so it was from the shaving soap. The rest of my hands where fine, just where I have creases in the top of my wrist where I'm assuming clay got caught. I had roughly a 5% SF in that recipe. Anyway.. I'm trying to avoid that. Should I pre soak the clay for a few hours first so it's fully saturated? Should I add it pre soaked into my oils after stick blending? What's the amount that should be added to 1lb of oils to where it's enough to feels a difference, but not so much where it ruins the shave Soap? Im thinking 2 tsp per pound of oils? And does it make a shaving soap slicker and better or is this a additive thing that is fading out over the years because it doesn't really give a better shave and is a waste of time? I know a good shave soap doesn't "need it" but I would like to make one successful batch and see, unless it really is not worth messing with.
