Our Natural Deodorants are made using Potassium Alum, a naturally occurring salt. It has been crushed up and suspended in liquid form and blended with anti-bacterial and therapeutic essential oils. The molecules of Potassium Alum are too large to pass through pores and into the bloodstream, so they don’t actually go into your body. But what they do is inhibit the growth of the bacteria that causes body odour. Be sure to shake your deodorant well and allow it to dry before getting dressed. You should expect our deodorant to last at least 6 hours, but we’ve had many customers report that it lasts all day.
