Schmidt does not use any chemicals or aluminium. Instead, their deodorant is made with Baking Soda and Arrowroot powder which had been combined with essential oils as well as nourishing Shea and Cocoa Seed Butters, and Vitamin E to provide a powerful anti-bacterial formula that has been proven to neutralise underarm odour and absorb excess moisture. All the deodorants include a key ingredient which is Hop oil, a highly antibacterial ingredient which prevents the growth of bacteria and helps to fight against odour. It also helps to preserve the product, meaning there is no need for synthetic preservatives. Hops extract is also rich in nutrient amino acids which help to nourish the delicate skin under the arm.
