These vegan deodorants are extremely effective. We use baking soda to deodorize, but not to prevent perpiration. We suggest trying a sample first if you have never used a baking soda deodorant before. We have formulated the product to be gentle for the majority of people by balancing it with rich Organic cocoa butter, however it can cause irritation in some people, especially if applied after shaving or waxing. Discontinue use if irritation occurs.
