About The Soap Digest
Plain-spoken, sourced guides to persimmon soap, nonenal and gentle cleansing for mature skin.

The Soap Digest publishes practical guides about a topic most people find awkward to ask about: the stale, oily body odor that can appear after 40, and the persimmon-tannin soaps sold to fix it.
What we publish
- Comparisons built from facts you can check: ingredient lists, prices, sizes, origins and guarantee terms, with the date we checked them.
- Explainers on the research behind nonenal and persimmon tannin, with links to the studies. We say where the evidence is thin.
- How-to and troubleshooting guides based on the questions real people ask in public communities like Reddit’s r/Menopause, r/AskWomenOver60 and r/bodyodor.
Who we are
The Soap Digest is written and edited by a small editorial team, with research and drafting help from AI tools. Every guide is checked against its sources before it’s published, and we correct errors when readers point them out. We don’t claim medical credentials, and nothing here is medical advice.
Ownership (please read)
The Soap Digest is owned by the same company that makes TanniBar, the persimmon tannin bar we rank first. We earn money when you buy it through our links. Links to every other brand are unpaid. We think you should know that before you read our recommendations, so we say it on every page. See our full disclosure and how we review.
