A simple mineral clay, nothing unnecessary
Bentonite clay doesn't need a long list of additions to be interesting. Its distinctive texture comes from the clay itself: dry and powdery in the pack, then noticeably thicker and more pliable as it takes up water. Ours is a sodium bentonite mineral clay supplied as a fine powder, ready for you to prepare fresh whenever you want to enjoy a traditional clay-mask ritual.
Sodium bentonite
This is the sodium form of bentonite, known for its pronounced swelling behaviour when mixed with water.
Fine powder
The soft, pale-grey powder is easy to measure a little at a time, with no added perfume or colouring.
A fresh face-mask paste
Add water gradually and stir to create a paste you can apply, then rinse away, as part of your skincare routine.
Naturally absorbent
Bentonite can take up water and oils at its surface. That physical absorbency is part of what makes it useful in a rinse-off clay mask.
Straightforward care
Keep the dry powder sealed and away from moisture, and mix only as much as you intend to use.
Ingredients
Bentonite clay
Sodium bentonite
A single-ingredient mineral powder; no added fragrance or colourants. For external use. Avoid inhaling dust; avoid the eye area. Patch test before wider use.
What exactly is bentonite clay?
Bentonite is a naturally occurring clay that develops as volcanic ash changes over time. It contains clay minerals from the smectite family, including montmorillonite. Although the dry powder looks quite unassuming, its behaviour changes dramatically once it meets water.
The variety supplied here is sodium bentonite. Its layered mineral structure allows water to move between the layers, causing the clay to swell and form a thicker, gel-like paste. This is the reason it is often chosen for traditional clay-mask routines: it blends readily with water and can be spread across the skin before being washed off.
Bentonite is sometimes described in sweeping terms as a “detox clay”. We prefer to be precise. The clay has genuine physical absorbent and adsorbent properties, but applying it to the skin is not evidence that it draws toxins or heavy metals out of the body. Its value on this page is as a simple, mineral-based ingredient for an external rinse-off skincare ritual.
How to prepare a simple bentonite clay face mask
The beauty of bentonite clay is that you control the consistency. Start with a small amount of powder, introduce water gradually and stir until the mixture becomes a smooth paste. There is no need to prepare a large amount or store a wet mixture for another day.
Mix fresh for each use and discard anything left over. Do not add essential oils or other ingredients without checking they are suitable for your skin.
Start with a little clay
Place a small spoonful of bentonite clay powder in a clean bowl. Avoid shaking the dry powder into the air.
Add water slowly
Stir in a little water at a time until the mixture is smooth enough to spread without running. Allow it a moment to thicken, adding a few more drops of water if needed.
Apply and rinse away
Patch test first. Apply a thin layer to clean, intact skin, keeping well clear of the eyes and lips. Rinse away gently before it becomes uncomfortably tight or causes irritation, then moisturise if desired.

A clay-mask ritual that keeps things simple
For a quick, no-fuss mask, mix a little powder with water until you have a paste that spreads easily. Use a clean bowl and utensils and prepare the mask just before applying it. Apply a thin layer to a small test area first; if your skin is comfortable, continue on clean, unbroken skin, avoiding the eyes and mouth. Rinse away with lukewarm water whenever the paste feels tight or uncomfortable. There is no need to let it crack hard on the skin.
Mix fresh
Prepare just enough powder and water for one application.
Keep it gentle
Use on intact skin and avoid rubbing aggressively when removing it.
Avoid eyes and dust
Keep the wet paste out of the eye area and avoid inhaling dry powder.
Rinse and finish
Wash away thoroughly with lukewarm water and follow with your usual moisturiser if needed.
Storage and care
Keep your bentonite clay dry between uses
The dry powder is best kept away from humidity. Close its container firmly after each use, store in a cool, dry place and use clean, dry utensils to remove what you need. Once water has been added, prepare the mixture for immediate use rather than storing the damp paste.
Keep dry
Moisture makes the powder clump and begin to swell.
Close securely
Reseal the pack after every use.
Store safely
Keep out of reach of children and avoid raising airborne dust.
Frequently asked questions
What is bentonite clay?

Is sodium bentonite different from calcium bentonite?
Yes. Both are forms of bentonite, but sodium bentonite generally swells more strongly in water. This is why it can produce a noticeably thick paste when mixed. The product sold on this page is sodium bentonite.
How do I make a bentonite clay face mask?

Can I eat or drink bentonite clay?
This product is sold for external use only. Do not ingest it. Although bentonite may be used in different industries under different specifications, this listing does not establish that it is suitable for consumption.
Does bentonite clay detoxify the body?
Bentonite is naturally absorbent and can bind certain substances in controlled settings. That does not mean a clay face mask removes toxins or heavy metals from the body. Here, we describe its physical properties and its use in an external skincare routine.
