Alum – Natural Deodorant & Aftercare
Purify, tone, and protect – the ancient way.
Used for centuries across Africa, the Middle East, and South Asia, alum (Potassium Alum) is a naturally occurring mineral salt known for its antibacterial, astringent, and odour-fighting properties. At Clean & Natural, our 100% natural Alum Bars offer a toxin-free alternative to chemical deodorants and aftershaves — ideal for those who want to keep their skincare routine clean, minimal, and effective.

How Alum Deodorant Works
Potassium alum does not block sweat glands.
When applied to damp skin, it leaves a light mineral layer on the surface. This helps create an environment that is less favourable to odour causing bacteria.
You sweat naturally. Odour is reduced.
Why Choose a Simpler Natural Deodorant?
Many mainstream deodorants and some popular natural deodorants include fragrance blends, essential oils and multiple added ingredients.
If you are looking for a fragrance free deodorant in the UK with a minimalist ingredient profile, alum offers a straightforward option.
How To Use
- Wash underarms thoroughly.
- Apply after showering while skin is slightly damp, or wet the stone under water.
- Glide over the full underarm area for 10 to 20 seconds.
- Allow skin to dry before dressing.
- Rinse the stone and allow it to air dry between uses.
Tip: Alum works best on clean skin before odour develops.
If the Alum Block Drops and Breaks
Alum is a natural crystalline mineral and may fracture if dropped. Do not throw it away.
Option 1 Use the pieces
Smaller pieces work the same. Wet and apply as normal.
Option 2 Use as powder
Crush broken pieces into a fine powder. Then either:
- Apply a small pinch to damp underarms
- Or mix with a few drops of water to form a paste
The powder works in the same way as the solid stone.
Frequently Asked Questions
Does alum stop sweating?
No. It does not prevent sweating. It reduces odour while allowing the body to perspire naturally.
Is potassium alum the same as aluminium?
No. Potassium alum contains aluminium within its natural mineral structure, but it is not the same compound as aluminium chlorohydrate or aluminium zirconium used in antiperspirants.
What is the difference between potassium alum and aluminium chlorohydrate?
Aluminium chlorohydrate is designed to block sweat ducts. Potassium alum is a naturally occurring mineral salt that remains on the surface of the skin and works by helping reduce bacterial activity.
Is alum deodorant suitable for sensitive skin?
Because it contains one ingredient and no fragrance, many people with sensitive skin prefer alum deodorant. Patch testing is recommended.
How long does one stone last?
With daily use, one stone can last several months.
