I want a deodorant that works all day but does not contain baking soda (irritant).

Yes — there are several good baking-soda-free options. If your priority is all-day odor control without baking soda, I’d look at these:

• Native Sensitive Deodorant Stick - $14.00 (Native)
• Lume Unscented Cream Deodorant - $15.00 (Lume)
• Humble Brands Sensitive Skin Deodorant - $10.99 (Humble Brands)
• Super Deodorant Original Formula - $25.13 (Super Deodorant Laboratories)

My shortlist

• Native Sensitive — probably the first one I’d try. It’s explicitly baking-soda-free and designed for sensitive skin, with magnesium-based odor control. Native claims up to 72 hours of odor protection.Native+1
• Lume Unscented — uses mandelic acid rather than baking soda to control odor. It claims all-day protection and up to 72 hours, and the unscented version is a particularly sensible choice if your skin is easily irritated.Lume Support+1
• Humble Sensitive Skin — a simpler formula and baking-soda-free; a good lower-cost option if you don't want a lot of ingredients.
• Super Deodorant — fragrance-free, baking-soda-free, and marketed for 24-hour coverage. It's a less conventional paste format but could be worth considering if typical natural sticks don't last on you.

One important distinction: these are deodorants, not traditional antiperspirants, so they primarily control odor rather than sweat. If you want something that also significantly reduces sweating, I can narrow this down to baking-soda-free antiperspirants instead.

If you tell me whether you prefer stick, roll-on, or cream and whether you want fragrance-free, I can give you 2–3 specific picks.

If baking soda irritates your underarms, I’d prioritize a fragrance-free, baking-soda-free formula. Also, if you want true all-day protection from sweat, an antiperspirant is more reliable than an aluminum-free deodorant.

My top picks

• Humble Brands Unscented Sensitive Skin Deodorant - $10.99 (Humble Brands)

1. Humble Brands Sensitive Skin Unscented — best simple deodorant

• Baking-soda free

• Fragrance-free

• Aluminum-free

• Magnesium hydroxide helps neutralize odor

• Specifically marketed for sensitive skin

• Good choice if you want to avoid both baking soda and fragrance.

• Native Sensitive Deodorant - $14.00 (Native)

2. Native Sensitive — best stick for long-lasting odor control

• Baking-soda free and aluminum-free

• Designed specifically for sensitive skin

• Native claims up to 72-hour odor protection.Target

• If fragrance bothers you too, choose the Fragrance Free version rather than scented varieties.

• Kosas Chemistry AHA Serum Deodorant — Fragrance Free - $20.00 (Nordstrom)

3. Kosas Chemistry — best if odor is your main concern

• Baking-soda free and aluminum-free
• Uses AHAs to make the underarm environment less favorable to odor-causing bacteria.
• The fragrance-free version is worth considering if your skin is particularly reactive.

But if you want the most dependable all-day option

Vanicream Anti-Perspirant/Deodorant would be my first choice. It is baking-soda-free, fragrance-free, alcohol-free, and uses 20% aluminum zirconium to reduce sweating. Vanicream states that it provides 24-hour protection and is formulated specifically for sensitive skin.Vanicream™

vanicream.com

If you don't want aluminum, I'd choose Humble or Native Sensitive. If you do want maximum all-day reliability, I'd choose Vanicream.

One other important point: baking soda isn't the only potential irritant. If your underarms are very sensitive, fragrance and essential oils can also cause problems, so fragrance-free is the safest place to start.realsimple.com

If baking soda (sodium bicarbonate) irritates your underarms, I’d look for a baking-soda-free deodorant with odor-control ingredients like magnesium hydroxide, zinc, probiotics/ferments, or acids (like mandelic acid). Note that most baking-soda-free options are deodorants, not antiperspirants—they control odor but usually won’t stop sweating unless they contain an antiperspirant active ingredient.Allure

Here are some good options for all-day odor protection without baking soda:

• Nécessaire The Deodorant Gel (Mandelic Acid) - $24.00 (Sephora)
• Native Sensitive Deodorant Fragrance Free - $13.99 (Walmart)
• Hume Supernatural Deodorant Stick - $15.49 (CVS)
• Humble Brands Unscented Sensitive Skin Deodorant - $10.99 (Humble Brands)

Best picks by priority

• Most likely to work all day:

• Uses mandelic acid to help reduce odor-causing bacteria.

• Baking soda-free and aluminum-free.

• Good choice if natural deodorants usually fail you.

• Best gentle everyday option:

• Baking soda-free, fragrance-free, and designed for sensitive skin.

• A solid first try if you want a traditional stick.

• Best if you want “natural” but effective:

• Uses prebiotics/probiotic ferments and minerals for odor control.

• Often a good fit for people who dislike baking soda formulas.

• Best budget sensitive-skin choice:

• Baking soda-free, fragrance-free, and uses magnesium hydroxide.

A few tips that can make even good deodorants perform better:

• Apply to completely dry skin (especially after showering).
• If you shave your underarms, try waiting a few hours before applying—freshly shaved skin is more prone to irritation.Allure
• If you react easily, start with fragrance-free; fragrance and essential oils can also trigger irritation for some people.Allure

If you tell me whether you need heavy sweat control, natural/aluminum-free, or fragrance-free only, I can narrow it down to the best 2–3 choices.

If baking soda (sodium bicarbonate) irritates your underarms, look for formulas that use magnesium hydroxide, acids like mandelic acid, probiotics/prebiotics, zinc, or odor-absorbing starches/clays instead. Allure NBC News A note: deodorants control odor; only antiperspirants with sweat-blocking ingredients reduce wetness, so an aluminum-free option may not keep you dry all day.Allure

Here are some good baking-soda-free options with strong all-day odor-control reputations:

My shortlist for “works all day + least likely to irritate” would be:

1. Dove 0% Aluminum Sensitive Skin (easy, affordable, gentle)
2. Nécessaire Deodorant Gel (if you dislike residue)
3. Native Sensitive Unscented (if you want a stick)
4. Vanicream Gel (if your skin is very picky)

If you tell me whether you need odor control only or also sweat/wetness control, and whether you prefer stick, gel, spray, or cream, I can narrow it down.

Finding a natural, all-day deodorant that skips baking soda is a game-changer if you have sensitive skin. Baking soda has a high pH that can disrupt your skin's acid mantle, leading to those painful red rashes.

Instead of baking soda, top-performing formulas rely on magnesium, alpha-hydroxy acids (AHAs) [3], or enzymes to neutralize odor-causing bacteria without the sting.[1]

Here are the best baking-soda-free deodorants that hold up all day:

Add to list A cult-favorite clean serum [3] that uses a unique blend of shikimic, mandelic, and lactic acids. It creates a low-pH environment where odor-causing bacteria can't survive [3], while lightly exfoliating and soothing with aloe vera and hyaluronic acid [3]. Available at Sephora.

Add to list A powerhouse cream packed with nourishing goat's milk, arrowroot powder, and magnesium hydroxide. It keeps odor at bay for a solid 24 hours without any greasy residue. You can find it directly on the Little Seed Farm site.[1]

Add to list Built on a nourishing grass-fed tallow base and powered by magnesium from Dead Sea salts and arrowroot powder, this option is specifically engineered for rash-prone skin and provides incredible all-day defense. Shop options on the Primally Pure Shop.[1]

Add to list Known for luxurious, naturally-derived scents and a smooth, water-based gel texture. It uses plant-derived enzymes and minerals instead of baking soda to keep you fresh. Explore the lineup at Corpus Naturals.

Add to list An extremely popular and affordable all-natural cream deodorant that uses a coconut oil and beeswax base with magnesium hydroxide to block odor for 12+ hours. Check it out at No Pong Deodorant.[1]

If you'd like to narrow this down, let me know:

• Do you prefer a stick, a cream you apply with your fingers, or a liquid spray?
• Are you looking for a fragrance-free/unscented option or something scented?
