Plain Jane soap was designed specifically for people with sensitive skin. It’s about as basic as it gets. No colors, no scent, no additives. The ingredient list is simple: palm oil (from a sustainable source), olive oil, coconut oil, castor oil, sodium hydroxide (the stuff that, when mixed with fat, becomes soap) and water. I’ve been actively seeking out people with sensitive skin to try my soap, and as of yet I haven’t found anyone who reacts to it.
I normally make this in round soaps, but the batch pictured was made while teaching someone to make soap, so we used the fancy mold, and so it has the textured top of rectangular soaps.
