The use of alum crystal
Potassium alum is used not only in natural deodorants, but for oral hygiene, dental care products, water purification and so on.
Potassium alum is soluble in water. The alum dissolves in warm water more quickly; therefore, moisture alum crystal in cool water, so it might be used longer.
Alum crystal is applied wet on skin. The crystal leaves invisible, thin mineral layer, which dries in quickly and permanently protects the skin from unpleasant odor. Alum crystal is recommended to use not only in the armpits, but also for feet hygiene.
We recommend the use a deodorant on clean skin. Natural deodorant protects against unpleasant odors up to 8-12 hours.
Alum crystal was used by grandparents to treat cuts after shaving. It effectively stops the bleeding and helps seal cuts.
The crystal diamonds are sliced by hand, so the difference in weight vary between + / - 10 g.
