Key Takeaways
- Microbeads (visible plastic scrubbing particles) were banned in the US and EU but synthetic polymers remain in most toothpastes.
- Watch the ingredient label for: polyethylene, PEG-(any number), acrylates copolymer, carbomer, polyquaternium, polypropylene.
- Plastic tubes themselves contribute particles to the paste over months of shelf life, choose recyclable aluminium tubes or glass jars where available.
- Hydroxyapatite-based toothpastes (Boka, RiseWell) work as well as fluoride for remineralisation per multiple 2024 trials.
- Toothpaste tablets (Bite, Unpaste) and glass-jarred powders (Uncle Harry's) eliminate plastic packaging entirely.
The hidden polymers to watch for
These ingredient names are all synthetic polymers (plastics) used to thicken, suspend, or texture toothpaste. None of them are microbeads (they were never banned) and many “natural” toothpastes still contain them.
| Ingredient name | Function | Concern |
|---|---|---|
| Polyethylene (PE) | Texture, mild abrasive | Direct microplastic |
| PEG (Polyethylene Glycol) with any number (PEG-8, PEG-40, PEG-100) | Humectant, surfactant | Petroleum-derived polymer; can contain 1,4-dioxane contaminant |
| Polypropylene (PP) | Thickener | Direct microplastic |
| Acrylates copolymer / Acrylates crosspolymer | Film former, thickener | Synthetic acrylic polymer |
| Carbomer | Thickener, suspending agent | Cross-linked polyacrylic acid polymer |
| Polyquaternium-10, -7, -39 | Conditioning agent | Synthetic polymer family |
| Polyvinyl pyrrolidone (PVP) | Film former | Synthetic polymer |
| Polysorbate-20, -80 | Emulsifier | PEG-derived; usually contaminated with 1,4-dioxane |
Why these are in toothpaste at all
Polymers solve real product-engineering problems: they thicken the paste so it doesn't separate, they create the smooth squeeze-out texture, they help suspend abrasives evenly, and they create the foam most consumers expect. Plant-based alternatives (xanthan gum, guar gum, cellulose) work but cost more and produce slightly different texture.
The packaging tube
Standard toothpaste tubes are multi-layer laminates of HDPE and aluminium foil, they aren't recyclable in most municipal programs and they leach particles into the paste during the months it sits on the shelf and in your bathroom. Recent alternatives:
- Aluminium tubes (Tom's of Maine has moved to recyclable aluminium for several products).
- Mono-material recyclable plastic tubes (Colgate, P&G are transitioning some products).
- Glass jars (Dr. Bronner's All-One; Uncle Harry's).
- Toothpaste tablets in compostable refill pouches (Bite, Unpaste) or paper boxes.

Hydroxyapatite vs fluoride: what the science says
Hydroxyapatite is the natural mineral that makes up tooth enamel. Synthetic nano-hydroxyapatite (n-HAP) has been used in Japanese toothpastes since the 1970s and has been studied increasingly in the West over the past decade. A 2024 systematic review in BDJ Openconcluded that hydroxyapatite toothpastes are non-inferior to fluoride for caries prevention in adults. They are a strong alternative for people who want to avoid fluoride for personal or health reasons. The American Dental Association still considers fluoride the gold standard, and either is a defensible choice.
How to read a toothpaste label
- Look for the active ingredient (sodium fluoride, sodium monofluorophosphate, hydroxyapatite, or none).
- Scan inactive ingredients for any of the polymer names in the table above.
- Check the packaging: tube material, recyclability claim, country of origin.
- Look for third-party certifications: EWG VERIFIED, MADE SAFE, Leaping Bunny (animal testing).
- Avoid microbead claims that aren't directly relevant, microbeads have been banned for a decade; the relevant fight is over polymers.
