Does Cosmetic glitter have microplastics?
The short answer
Yes, unambiguously — conventional glitter is cut plastic film, usually PET. This is the one category where the answer is not contested: the EU restricted loose microplastic glitter in October 2023 as an intentionally-added microplastic.
Why Cosmetic glitter scores 60
The product is the plastic — this is not packaging leaching into contents, it is microplastic sold by the pot
Applied directly to skin, near eyes, and it washes straight down the drain
Regulators have already made the determination: the EU restriction names it as intentionally-added microplastic
"Biodegradable" glitter is usually modified cellulose, which is genuinely different — but the claim is loosely policed and worth checking

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
Nobody has measured dermal uptake or the dose from a night of wearing it, and honestly nobody needs to for the decision to be clear. The open question is the alternatives: cellulose-based glitters vary in what binds and coats them, and independent testing of those claims is thin.

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Limitation: An industry-funded modelling exercise, not a laboratory study, and not peer-reviewed.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-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.
- agency2026
US FDA — States that current scientific evidence does not demonstrate that the levels of microplastics detected in foods pose a risk to human health, while listing detection and characterisation as a research priority.
Limitation: A statement about the state of evidence, not a finding of safety. "Not demonstrated to be harmful" and "demonstrated to be harmless" are different claims, and the agency is explicit that the research is ongoing.
