Microplastics in Deodorant: Brands Ranked (Native, Dove, Schmidt's, Lume) 2026

Last updated: June 20, 2026

Why deodorant is a uniquely high-exposure cosmetic

Deodorant is applied daily to thin skin in a warm, moist environment (underarms) and stays in contact for 12–18 hours. The combination of:

• Daily application without rinsing
• Warm skin temperature accelerating dermal absorption
• Moist environment increasing solubility of carrier ingredients
• Thin axillary skin (much more permeable than most other body skin)
• Direct lymph node proximity (concerning for any bioaccumulative ingredient)

...makes deodorant ingredient choice meaningfully more important than most personal-care choices. The microplastic angle adds another layer: every modern stick deodorant formulation uses polymer film-formers to make the stick glide smoothly and adhere to skin.

What the plastic ingredients in deodorant actually do

• PEG-8, PEG-100 stearate, PEG-12 dimethicone: polyethylene glycol compounds. Used as emulsifiers and emollients. EU has restricted some PEG-derivatives in rinse-off products under REACH but they remain in leave-on cosmetics.
• Propylene glycol: not strictly a plastic but a synthetic petrochemical humectant. Common in stick deodorants for smooth application. Skin-irritant for some users.
• Dimethicone: silicone polymer (chemically a liquid plastic). Creates a smooth, water-resistant film on skin. Common in all major-brand antiperspirants.
• Acrylates copolymer / acrylates/octylacrylamide copolymer: polymer film-formers. Help antiperspirant active ingredients stay on skin and resist sweat wash-off.
• VP/VA copolymer, VP/eicosene copolymer: vinyl polymer film-formers used in long-lasting and clear-finish deodorants.
• Cyclopentasiloxane, cyclomethicone: volatile silicone solvents used as carriers; evaporate after application but leave behind their non-volatile silicone film.

None of these is acutely toxic. The concern is chronic exposure: applying any of them daily for years to highly permeable skin, near lymph nodes, accumulates a real bioavailable polymer load.

Ingredient lists vary by scent and country market. Always check the specific stick you're holding. The MicroPlastics app reads the barcode and parses the ingredient list automatically.

Why "natural" doesn't mean plastic-free

The natural deodorant category has expanded dramatically since 2020 (Native acquired by P&G, Schmidt's by Unilever). With that expansion came a quiet reformulation creep: brands that started with pure plant-oil + baking soda formulations now often include propylene glycol or dimethicone to improve glide and reduce baking-soda irritation.

Three common natural-deodorant ingredient surprises in 2026:

• Native “Plastic Free” line is genuinely plastic-free in ingredients but the original Native sticks still contain propylene glycol on certain scents. Check the variant.
• Lume Whole Body Deodorant markets as natural but contains dimethicone, PEG-12 dimethicone, and acrylates/octylacrylamide copolymer. Effective at odor control; not a plastic-free pick.
• Tom's of Maine Long Lasting contains propylene glycol on most scented variants. The unscented and certain mineral-based SKUs are cleaner.

The truly plastic-free natural deodorants are typically the ones that still use baking soda + magnesium hydroxide for odor control: Each & Every, Soapwalla, Meow Meow Tweet, and Schmidt's Sensitive Skin Formula.

Cream/paste deodorants — usually the cleanest formulations

Cream and paste deodorants (Soapwalla, Meow Meow Tweet, some Earth Mama) don't need the polymer binders that hold a twist-up stick together. Their formulations are typically: coconut oil + shea butter + baking soda or magnesium + clay + essential oils. That's it.

The trade-off is application: you apply with your fingers from a jar rather than a convenient twist-up. Most users adapt in a week. The other trade-off is glass jars are less travel- friendly than sticks.

For users who want the simplest possible ingredient list, cream/paste in a glass jar is the cleanest format on the market.

Picks by use case

For odour-only protection (no antiperspirant needed)

Each & Every. Pure plant-oil formulation, magnesium hydroxide for pH balance, no plastic ingredients, cardboard tube option. Best clean stick in the category.

For sensitive skin / baking soda intolerance

Schmidt's Sensitive Skin Formula. Uses magnesium hydroxide instead of baking soda. Clean ingredient list, gentle for skin that reacts to standard natural deos.

For minimum-ingredient purist

Soapwalla Citrus Cream. Coconut oil + clay + baking soda + essential oils in a glass jar. Six-ingredient formulation. Apply with fingertips. Cleanest formulation on the market.

For travel

Schmidt's Sensitive Skin Stick in the travel-size 1oz. TSA-compliant solid, stays in carry-on without the 3-1-1 liquid limit.

If you actually need an antiperspirant

All aluminum-based antiperspirants are higher in plastic- ingredient flags. If you need sweat blocking specifically (not just odor control), Mitchum Unscented Stick is the comparatively cleanest of the antiperspirant category, but still contains cyclopentasiloxane and acrylates copolymer. Consider whether you actually need antiperspirant — most users only need odor control.

Scan your current deodorant in 5 seconds

1. Open the MicroPlastics app on your phone.
2. Tap scan, point your camera at the barcode on the deodorant package.
3. The app returns a 0–100 microplastic risk score plus the cleaner same-format alternative in your budget.
4. If your current deodorant scores above 60, the recommended swap is usually a one-click view of the cleaner SKU on Amazon or your usual retailer.
