The best natural deodorants are ones that keep you smelling fresh, are made with quality ingredients, and don’t irritate your sensitive underarm skin. The problem: some of them contain baking soda, which absorbs sweat — but can also cause a rash or irritation for some people. No thanks!

We asked an expert about why this goes down with these particular types of natural deodorants. “Baking soda has an alkaline pH,” explains Dr. Debra Jalimanboard-certified NYC dermatologist, Assistant Professor of Dermatology, Icahn School of Medicine at Mount Sinai and author of Skin Rules: Trade Secrets from a Top New York Dermatologist. “A rash can be caused when the pH balance is thrown off.” If you’re part of the pH-sensitive set, looking for natural deodorants without baking soda may be the way to go.

But is it possible to find natural deodorants without baking soda that actually work to keep BO at bay, without making your pits feel like they’re on fire? Yes! Because luckily, more and more brands have launched natural deodorants that actually work, so finding one of the best natural deodorants that you can stick with is easier than ever. What gives a natural deodorant without baking soda its stay-dry power, you ask? Common substitutions for the sweat-absorbing ingredient include magnesium hydroxide powder, arrowroot powder, or corn starch.

Before you go forth on your natural deodorant-buying journey, though, it’s worth mentioning that baking soda isn’t the only ingredient that can cause irritation or an allergic reaction. Some people are allergic or sensitive to fragrance, parabens, alcohol, and other things, says Dr. Jaliman, so read labels carefully before you buy.
