Anti-perspirants are designed to block sweat from coming out of the body. We believe this to be unhealthy as the body is designed to sweat and it is part of a healthy elimination process. However, we do understand that sometimes people need a deodorant. This does not stop the body from sweating but it does slow down the bacterial breakdown of the sweat which is what eventually causes the bad smell.
A common material found in commercial brands is Aluminium Hydroxychloride (INCI Name: Aluminium Chlorohydrate). Its salts act as a sweat inhibitor, closing off the skin's sweat pores so the sweat is unable to come out. We don't like this and believe it is not good for our overall health.
We prefer to use Deocrystal Stone Powder instead (INCI Name: Potassium Alum). This is a natural deodorant that has a molecular size that is too large to be absorbed into the skin. It stays on the surface where it inhibits bacterial growth, thus giving a deodorant effect.
