Does Toothpaste tube have microplastics?
The short answer
Two separate questions, and only one is still live. Microbeads in toothpaste were banned in the US, UK and EU and are gone from mainstream brands. The tube is the remaining issue: a laminate you squeeze and deform every single day.
Why Toothpaste tube scores 33
A flexible laminate deformed at every use, which is the squeeze-bottle mechanism applied twice a day
Months of contact between the paste and the inner polymer layer
The microbead question is genuinely closed in regulated markets — that ban worked
Other synthetic polymers can still appear on an ingredient list as thickeners and film formers
Where the 33 comes from
Five components, added. The page renders the parts rather than a stored total, so the number cannot disagree with the reasoning behind it.

What material touches the contents, over how much surface area, for how long. Glass and steel score near zero here; a film pressed against fatty food scores near the top.
Heat, abrasion, flexing, repeated opening, reuse beyond design life. The same bottle scores differently in a fridge and in a hot car.
What a laboratory actually counted, for this product or its category. A high number here means real particles were measured, not that the material looks suspicious.
How this specific polymer behaves — brittleness, fat solubility of its additives, thermal stability, whether it is a polymer named in existing restrictions.
What happened before you bought it. Retort sterilisation inside the pack, hot-filling, and pressurised brewing all happen at the most migration-favourable moment.
What we don't know
The tube has not been measured. For what is actually in the paste, the ingredient list is checkable and our free checker will read it — which is a better answer than a score, because formulations differ far more between products than tubes do.

This page scores Toothpaste tube as a product. Formulations, packaging and suppliers change, and the specific item you own has its own condition — a scratched pan and a new one are not the same object. Scan yours for a score built from what is actually in front of you.

Each with the finding we use it for and the limitation that finding carries — because a study quoted without its boundaries is how this subject got so noisy.
- report2026
Earth Action 2026 — Estimated roughly 1,000 tonnes of microplastics migrate from packaging into food and drink annually — about 130 mg per person per year — with PET bottles responsible for around a third, and found UV exposure can raise release up to 100×.
Limitation: An industry-funded modelling exercise, not a laboratory study, and not peer-reviewed. We use it for the relative ranking of formats rather than for any absolute number.
- peer-reviewed2020
Sobhani 2020 — Simply tearing, cutting or twisting open plastic packaging generates microplastics at the opening — 10–30 nanograms per 300 cm of tear.
Limitation: Mass, not particle count, and it does not follow whether those particles land in the food. It is the reason cap and seal design belongs in an exposure score at all.
- peer-reviewed2022
Zangmeister 2022 (NIST) — Nylon bags, LDPE food-storage bags and similar single-use plastics shed trillions of sub-100 nm particles per litre in ordinary contact with water.
Limitation: Deionised water at controlled temperature. Nanoparticle counts are inherently large numbers; the study is about their existence and quantity, not their fate in the body.
