Soap

My husband has stage four colon cancer that is treatable, but incurable. He is currently in very good health (despite the cancer) and receiving treatment after a long break. For five years we've been using home and personal products from a "natural" company, but for several reasons have discontinued our membership. I'm not looking to replace these items with others that are non-toxic and don't contain a lot of artificial ingredients. Does anyone have a suggestion for a good bar soap that moisturizes, but doesn't irritate very sensitive skin? I've seen liquid soaps, but would like a bar since that's what my husband prefers. I have several I'm considering, but thought asking here might save me some time. Thank you.
