Potassium alum is a naturally occurring salt. Unlike aluminium which can be absorbed by the skin, these molecules are too large to pass through the pores. As a result, body odor is reduced because there is no environment for bacteria to grow. This makes potassium alum a great ingredient to use in our natural deodorants.
The salt is crushed and then suspended in a liquid which means the deodorant goes on wet but when the minerals dry, they sit on the skin as a protective layer. So say goodbye to harsh antiperspirants and welcome a natural deodorant into your life!
