Deonatulle Soft Stone W Deodorant 20g — Japan's Alum Crystal Deodorant
Deonatulle Soft Stone W is one of Japan's most trusted deodorant sticks, powered by natural potassium alum (明礬) — a mineral crystal with centuries of use as a natural odor inhibitor. Unlike conventional deodorants containing aluminum chloride, Soft Stone W uses alum, which works by temporarily tightening pores and creating an environment unfavourable to odor-causing bacteria. The "W" stands for double protection: against both sweat and odor.
Compact at just 20 g, it's a favourite for travel, gym bags, and those who prefer mineral-based formulas. Apply to clean, dry skin for best results.

Key Benefits
- ✓ Natural potassium alum crystal — mineral-based odor control without synthetic aluminum chloride
- ✓ Double action: inhibits sweat and neutralises odor simultaneously
- ✓ Compact 20 g stick — ideal for travel and on-the-go use

How to Use
- Wash and thoroughly dry underarms or problem areas before application.
- Roll or glide the stone directly onto dry skin — 2–3 passes per side.
- Allow to dry completely before dressing.
- Rinse the stone tip with water after each use and pat dry before capping.
Frequency: Daily, after bathing or showering.
Tip: For best odor protection, apply immediately after bathing while pores are clean. The alum crystal works by inhibiting bacterial growth — results accumulate with consistent daily use.
Ingredients
Potassium Alum (Alumen), Ethanol, BG (1,3-Butylene Glycol), Purified Water.
This is a mineral-based formula. Potassium alum is not the same as aluminum chloride or aluminum zirconium used in conventional antiperspirants.
Cautions
- For external use only.
- Do not apply to broken, irritated, or freshly shaved skin — the product contains alcohol which may cause stinging.
- Perform a patch test before first full use if you have sensitive skin.
- Discontinue use if redness, itching, or irritation develops.
- Keep out of reach of children.
- Store away from direct sunlight and heat; protect the stone from impact (it is a crystal and may crack if dropped).

FAQ
Is this safe for sensitive skin?
Yes — Soft Stone W uses natural potassium alum rather than synthetic antiperspirant compounds, and is fragrance-free. However, it contains ethanol, so avoid applying to freshly shaved or broken skin. Do a patch test if you are prone to reactions.
What is the difference between potassium alum and conventional antiperspirant?
Conventional antiperspirants use aluminum chloride or aluminum zirconium, which physically plug sweat ducts. Potassium alum works differently: it is mildly astringent and creates a surface environment that inhibits odor-causing bacteria without blocking pores.
How long does one 20 g stick last?
With daily use on two underarms, most users report 3–5 months. The stick shrinks slowly as it is a solid crystal mineral.
Is this the genuine Japanese product?
Yes — Tsujimoto Market sources Deonatulle Soft Stone W directly from Japanese distributors. Every item ships from our warehouse in Kobe, Japan.
How long does shipping take?
Orders are dispatched within 2–6 business days from Kobe. Delivery typically takes 7–20 days depending on destination. A tracking number is provided after dispatch.
