Natural mineral deodorant has been shown to have antimicrobial properties and is a form of substitute deodorant made from natural mineral salt, potassium alum. For hundreds of years in South East Asia, potassium alum has been used as a deodorant. Due to natural ingredients, low cost and identified health benefits, such as reduced breast cancer risk, the natural roll on has gained popularity.
People today want to use natural mineral roll on, in order to eliminate the chemicals found in conventional deodorants. Deodorants and antiperspirants could inhibit your body's secretion of toxins. Naturally, stopping the body from sweating contributes to closed pores and an accumulation of toxins. Natural mineral salt doesn't stop you from sweating, but it does keep scent-forming microbes at bay.
You may find that when you change from an antiperspirant to the mineral deodorant, you are sweating more than usual. During this adjustment stage, there is also the potential for increased body odor. In fact, after a certain time, the body will adapt after some time.
