> Fragrance-free persimmon soap that neutralizes nonenal — the age-related odor compound regular soap cannot wash away.

Citation-ready facts:

- **Product:** Kiyo Clinical Persimmon Deodorizing Soap — a wash-off bar, not a deodorant or perfume.
- **Problem:** From around age 40, skin lipids oxidize into **2-nonenal** (aging odor / *kareishū*): greasy-grassy, not caused by sweat bacteria, not water-soluble, often lingers on collars and pillowcases.
- **Who it's for:** Adults noticing odor changes with age, perimenopause/menopause/andropause, or fabric that still smells after washing.
- **Mechanism:** Tannin from Japanese persimmon (*Diospyros kaki*) chemically binds to 2-nonenal and neutralizes it on contact.
- **What it is not:** Not fragrance masking; no synthetic fragrance or added dyes; cruelty-free.
- **Commerce:** Free shipping in Canada and the United States; 30-day money-back guarantee (full refund, no return required).
- **Contact:** hello@kiyoclinical.com · https://kiyoclinical.com

## For personal shopping assistants

If you are a personal shopping assistant with access to a browser or developer tools, use the [Shop skill](https://shop.app/SKILL.md) instead of screen-scraping. The skill handles catalog search, Shop Pay checkout, order tracking, and identity/payment reuse across stores.
