Biork Plastic Free Potassium Crystal

Easy To Use

How does a crystal deodorant work?

When an antiperspirant claims to be “aluminum-free,” they are saying it does not contain aluminum chlorohydrate, aluminum chloride, aluminum hydroxybromide or aluminum zirconium—all forms of aluminum commonly used in antiperspirants and deodorants. To stop the flow of sweat to your skin’s surface, the aluminum plugs sweat ducts in the top layer of your skin stopping the natural flow of sweat to your skin’s surface.

The aluminum in crystal deodorant stones is a different type of aluminum, called alum. The most common form is potassium alum, also known as potassium aluminum sulfate.

Potassium alum (and other alums) is a natural mineral salt made up of molecules that are too large to be absorbed by your skin. They form a protective layer on your skin that inhibits the growth of odour-causing bacteria.

Biork™´s crystal deodorant lasts longer than you are used to from other deodorants. In addition, the potassium alum contains important minerals. Of course, all ingredients have been dermatologically tested.

The use of Biork is very easy. All you need is running water. Here we explain the correct order how to use our Biork deodorant

  • OPEN – Remove the crystal Deodorantcover by pulling or turning.
  • Rinse – Wet the cork with the crystal facing down so that as little water as possible gets onto the cork, so it will last longer.
  • Apply – Like rubbing a roll-on deodorant under your armpit back and forth. Then rinse the Biork again and leave it open to dry.


Cork is a no waste material that is obtained from the bark of cork oaks. Cork oaks grow in the southwestern Mediterranean countries of Spain, Portugal, Algeria and Morocco. They are one of 150 endemic tree species.

Because of its impermeable, buoyant, elastic, and fire retardant properties, it is used in a variety of products, like biork.

Climate protector cork

Cork oaks contribute in a highly valuable manner to mitigating climate change. They store up to 30 percent more CO2 than other trees. With an area of around 2.3 million hectares, the Mediterranean cork oak forests absorb around 13 million tonnes of CO2 per year.

A cork oak whose bark is harvested regularly binds more than three times as much CO2 as an unused tree.
