Finest Quality Natural Deodorant on Earth

Osma Laboratoires  produces the world’s best natural deodorant in France since 1957 (they also make a spectacularly unique shaving soap with alum!)

100% Potassium Alum

These stones are made only of potassium alum.  Ammonium aluminum sulfate (aka ammonium alum), commonly found in many competing alum stones, is never present here.  Potassium alum is more gentle.

Meets the Needs of Men or Women Alike

Whether you’re a man or a woman, it does not matter with these fine natural deodorant stones.  They will assuredly control odor {note that alum stones do not control perspiration – Osma’s roll on deodorant is appropriate for this need (and is much more costly per use)}.

No Odor Added, No Odor Emerging

These alum stones do not add any detectable odor to your skin, which is great for incorporating with your preferred aftershave, cologne, parfum, etc.

Superior Water Content, Superior Structure

First, this natural deodorant stone has more water weight than all its competitors’ stones, for a more soothing feel.   Secondly, the stone itself is less what than the others – because of that extra water.  Lastly, Osma stones wear evenly without crumbling or losing the uniform texture as others so often do.  Indeed, we’ve never heard of or seen an Osma stone develop the common granular or scratchy texture.  The natural crystal deodorant from Osma stays smooth as you use it and always feels gentle.

Extremely Economical Natural Deodorant

These alum stones are costly in terms of comparison to inexpensive alum found at an Indian grocer, for example, but they wear evenly, never crumble, contain on ammonium alum, and cost just pennies per day.

How to Use

Leave the skin to be addressed moist, splash stone with water, and apply stone to area of concern until stone and skin are dry.  When using as a post-shaving astringent, move with the beard growth direction on the face.

Different Forms Available

• The flat-faceted “BPO” and “BP2C” are marketed towards shavers.
• The others are marketed as deodorants.
• Each can be employed for either task; only the shape and size and packaging are altered.

The “BPO” weighs ~2.8 oz (80g) and takes up a 1.5 x 2.3 x 1.0″ (38x59x24mm) chunk in a travel bag. Waxy box somewhat durable as a practical traveler.

The “BP2C” size is ~45% more of product than the entry-size “BPO”, the most important part of choosing the bigger one is an easier time grabbing it. Delivered in plastic case.  Weighs ~4.4oz (126g).  Consumes 1.88 x 2.92 x 1.05″ (48x74x26.5mm) of space.

The “STDEO” is 1.25 x 3.15″ (31x80mm), expertly formed for use as a comfortable natural deodorant.  The container holds the alum firmly in place during application and gives its enough protection for travel.  Wet the top and apply right to the armpit until dry. It works! Tube/alum take up 1.6 x 4.5″ (41x114mm) of space and weighs 4.9 ounces (140g). You’re paying some for the reservoir here, so if you just want 100g of alum form itself in a plastic screw-bottom shell case exclusively for stay-at-home you should choose “STBCR”.

The “STBCR” version is a ~40x55mm alum form in a plastic screw-bottom (aka helicoid) shell case which doesn’t offer enough protection for travel.

“BL150” is a ~150g hand formed disc.
