Bottom line up front: If you want an EWG-rated deodorant that actually works, Native Unscented is our top pick — confirmed LOW HAZARD on EWG’s Skin Deep® database, aluminum-free, fragrance-free, and proven daily odor control. Crystal Fragrance Free is our #2 (two-ingredient mineral-salt formula, also LOW HAZARD). See all 7 picks in the table below.
Deodorant is applied daily, often to freshly shaved or sensitive skin, which is why more consumers are checking EWG's Skin Deep® database before buying. The Environmental Working Group (EWG) is an independent nonprofit that rates personal care products based on their ingredient profiles. This guide covers seven aluminum-free deodorant brands listed in EWG's Skin Deep® database, with each product's EWG hazard rating stated clearly. Not every deodorant here rates the same on EWG's scale, and we show you the actual designation for each so you can make an informed choice.
We surface EWG's publicly available Skin Deep® ratings. We do not conduct our own ingredient assessments and are not affiliated with the Environmental Working Group. For the most current score on any product, check ewg.org/skindeep directly.

Why EWG Skin Deep Flags Many Conventional Deodorants
Deodorants and antiperspirants are applied daily to thin underarm skin, where absorption may be higher than on other body areas. EWG's Skin Deep® database evaluates personal care products including deodorants and commonly flags:
- Aluminum compounds (aluminum chlorohydrate, aluminum zirconium tetrachlorohydrex): The active ingredients in antiperspirants; EWG rates them as moderate concern for neurotoxicity and breast tissue health in some studies (evidence limited and ongoing)
- Synthetic fragrance (“fragrance” or “parfum”): A catchall for undisclosed chemical mixtures; EWG rates fragrance as moderate-to-high hazard due to allergen potential and undisclosed endocrine-disrupting compounds
- Parabens (methylparaben, propylparaben): Preservatives flagged for potential hormonal activity
- Propylene glycol: A solvent used for texture; EWG rates certain concentrations as a skin sensitizer and penetration enhancer
- Triclosan: An antibacterial ingredient banned from some products but still present in some deodorant formulas; rated high hazard by EWG
EWG Skin Deep® scores products on a 1–10 hazard scale. Scores of 1–2 (LOW HAZARD, green) indicate the ingredient profile has low evidence of concern across EWG’s evaluated categories. Scores of 3–6 are MODERATE HAZARD; 7–10 are HIGH HAZARD. We state each product’s hazard designation clearly rather than treating all these deodorants as equivalent.

EWG Skin Deep® status: Listed in EWG’s Skin Deep® database — rated MODERATE HAZARD (product 1013042; check ewg.org/skindeep for current score)
Schmidt’s Sensitive Skin formula skips baking soda in favor of magnesium hydroxide as the primary odor-neutralizing ingredient, making it a go-to for people who experience underarm irritation from traditional natural deodorant formulas. Free of aluminum, synthetic fragrances, parabens, and phthalates. Schmidt’s is one of the more extensively listed natural deodorant brands in EWG’s Skin Deep® database. This specific formula carries a MODERATE HAZARD rating; if a LOW HAZARD rating is your threshold, see Native Unscented, Crystal, or Humble Brands below.

It’s the higher-coverage Schmidt’s formula, aimed at active users who want more protection without aluminum. Free of synthetic fragrance and parabens.

ATTITUDE’s Natural Deodorant in Sandalwood & Cedar is EWG VERIFIED® — meeting EWG’s strictest standards for ingredient safety and full transparency.

5. Crystal Body Deodorant, Fragrance Free (Stick)
EWG Skin Deep® status: Rated LOW HAZARD on EWG’s Skin Deep® database (product 974413)
Crystal’s mineral salt stick is one of the simplest deodorant formulas available: ammonium alum, water, and nothing else. Ammonium alum is a naturally occurring mineral salt distinct from the aluminum chlorohydrate found in antiperspirants. It works by forming a thin layer on the skin surface that inhibits odor-causing bacteria without the absorption associated with antiperspirant aluminum salts. The formula earns a LOW HAZARD rating in EWG’s Skin Deep® database. One stick can last several months with daily use, making it among the most economical options on this list.
Active odor fighter: Ammonium alum (mineral salt)
Key free-froms: No antiperspirant aluminum, fragrance-free, paraben-free, no artificial dyes
Best for: Minimalist ingredient preference, those who react to baking soda or magnesium formulas, budget-conscious shoppers

Kopari’s coconut oil-based deodorant is baking soda-free and built on a blend of coconut oil and tapioca starch for moisture management, with magnesium hydroxide for odor control. Free of aluminum, parabens, and synthetic fragrances. Kopari is one of the more popular clean deodorant brands in specialty retail and appears in EWG’s Skin Deep® database.

Humble Brands makes a baking soda-free aluminum-free deodorant stick that earns a LOW HAZARD rating in EWG’s Skin Deep® database. The formula uses arrowroot powder and magnesium hydroxide for odor control, not baking soda, making it a solid option for anyone who has experienced underarm irritation from baking soda-based natural deodorants. Free of aluminum, synthetic fragrances, and parabens. One of the few LOW HAZARD-confirmed picks on this list that is also baking soda-free, which makes it particularly useful for the subset of natural deodorant users who have already ruled out baking soda formulas.

Key free-froms: Aluminum-free, baking soda-free, fragrance-free, paraben-free
Best for: LOW HAZARD priority combined with baking soda sensitivity; those who want a short, simple ingredient list

Tips for Switching to an EWG-Listed Deodorant
Expect a transition period. Switching from aluminum-based antiperspirants often brings 2–4 weeks of increased sweating and temporary odor changes as the body readjusts. This is a normal physiological response and typically resolves on its own.
Baking soda sensitivity is common. Underarm redness and irritation from baking soda affects a meaningful portion of natural deodorant users. If that describes you, the baking soda-free options on this list are Schmidt’s Sensitive Skin, Kopari, Crystal mineral salt, and Humble Brands.
EWG score matters as much as marketing language. This list includes deodorants at different EWG hazard tiers. If a confirmed LOW HAZARD rating is your priority, focus on Native Unscented, Crystal, and Humble Brands; all three carry confirmed LOW HAZARD designations in EWG’s database. The two Schmidt’s formulas carry MODERATE HAZARD ratings in EWG’s database, and we include them because they remain among the most searched natural deodorant brands; knowing their EWG status is useful context. Tom’s and Kopari have scores we could not confirm at time of research.
Application technique helps. Natural deodorants work best applied to clean, dry skin. Some formulas absorb better a few minutes after showering rather than immediately. For crystal mineral salt, keep the stick slightly damp or wet the underarm skin before applying.
Consider the season. A lighter formula (crystal mineral salt or magnesium spray) tends to work well in cooler months; a thicker stick with arrowroot powder may perform better in heat and humidity.
Frequently Asked Questions
Q: What does MODERATE HAZARD mean on EWG Skin Deep®?
EWG’s MODERATE HAZARD designation (scores 3–6 on the 1–10 scale) indicates the product’s ingredient profile has some evidence of concern in at least one hazard category evaluated by EWG. It does not mean a product is unsafe, but it indicates the ingredient profile is not at the lowest-hazard level. Consumers who want to minimize exposure to ingredients EWG flags should prioritize LOW HAZARD options. We label each product on this list clearly so you know which tier applies.
Q: Does EWG rate aluminum in deodorant as toxic?
EWG rates aluminum compounds used in antiperspirants as moderate concern — not high hazard — based on limited evidence related to neurotoxicity and breast tissue research. EWG recommends caution, particularly for frequent application, but does not characterize antiperspirant aluminum as definitively toxic. The science remains under study; we present EWG’s ratings without making independent health claims.
Q: What’s the difference between a deodorant and an antiperspirant?
Deodorants neutralize odor-causing bacteria without blocking sweat. Antiperspirants use aluminum salts to physically block sweat glands. Every product on this list is a deodorant, not an antiperspirant. If sweating rather than odor is the primary concern, discuss options with your doctor.
Q: Are natural deodorant sprays rated differently by EWG?
EWG rates individual formulations, not product formats. The same principles apply — aluminum, synthetic fragrance, and parabens in a spray raise the hazard score just as they do in a stick. Look up the specific spray product in EWG Skin Deep for its current rating.

The Bottom Line
All seven deodorants on this list appear in EWG’s Skin Deep® database. Three — Native Unscented, Crystal Body Deodorant, and Humble Brands Simply Unscented — carry confirmed LOW HAZARD ratings. Two Schmidt’s formulas carry MODERATE HAZARD ratings in EWG’s database; we include them because they’re among the most searched natural deodorant brands and their EWG status is useful context for comparison shopping. Two products (Tom’s of Maine and Kopari) have scores we were unable to confirm at time of research — we recommend checking ewg.org/skindeep for current ratings on those.
