We typically think of hot flashes in conjunction with menopause, but if you’re pregnant, you may experience some hormonal overheating and night sweating too. In fact, 35 percent of pregnant women surveyed in one study reported these symptoms.

So when you’re sweating more in general, you’re going to feel the urge to keep applying deodorant to keep feeling fresh. The thing is, there are some ingredients in health and personal care products like deodorant that you should avoid during pregnancy, including triclosan, phthalates, and parabens, according to the American College of Obstetricians and Gynecologists (ACOG). These chemicals can disrupt your endocrine system, which produces hormones, and be dangerous during pregnancy.

ACOG also recommends avoiding synthetic fragrances, which are also made with chemicals. The label should say either “fragrance-free” or not include “fragrance” in the ingredient list, even if the product is listed as “unscented.” Some products that have a mild scent are made with natural herbs or oils should be safe during pregnancy, as long as you don’t have skin allergies to those ingredients.

And then there’s the ultimate controversial deodorant ingredient: aluminum. There’s not much concrete research suggesting that aluminum that is present in some deodorants is actually harmful. One small South African study claims that high maternal intake of elements like aluminum could lead to toxicity in infants, but it’s unclear what the exact threshold of exposure is. The CDC can’t confirm for sure whether or not aluminum can cause birth defects — so the best bet might be to avoid aluminum in deodorant while you’re pregnant, at least.

Based on that guidance, we rounded up some chemical-free, aluminum-free, and fragrance-free pregnancy-safe deodorants to keep you feeling clean throughout every trimester.
