Does Essentia have microplastics?
The short answer
Yes, on the same basis as every PET bottle, and the alkaline processing is irrelevant to it. Ionisation changes the water chemistry before filling; the bottle it then sits in for months is unchanged, and the bottle is what this score is about.
Why Essentia scores 60
Standard PET bottle wall in contact with the water for the whole shelf life
Higher pH does not protect a polymer — if anything, alkalinity is a mild hydrolysis condition for polyesters
Sold in large multipacks stored at room temperature at home
Cap and neck-thread abrasion at every open and close

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
No brand-specific test, and no study has looked at whether pH affects particle release from PET at all. That is a real and answerable question that nobody has answered, so we score the bottle and say the alkaline claim is orthogonal rather than protective.

Better options
Ordered by how much they change, not by how much they cost.
Filtered tap water
the alkaline benefit is contested; the bottle is not
Glass-bottled mineral water
naturally alkaline sources exist in glass

This page scores Essentia 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.
- peer-reviewed2024
PNAS 2024 (Qian) — Counted roughly 240,000 plastic particles per litre in bottled water, about 90% of them nanoplastics that earlier optical methods could not see at all.
Limitation: Three unnamed US brands, small sample. It measured particles, not absorption or any health outcome, and the brands were not disclosed — so it cannot be attributed to a specific label.
- peer-reviewed2018
Mason 2018 — 93% of 259 bottles across 11 international brands contained microplastic; an average of 325 particles per litre across all size classes.
Limitation: Nile-red staining and optical microscopy only reliably resolve particles above ~100 μm, so its counts are a floor, not a total. Lower numbers here do not mean less plastic than the 2024 study — they mean a less sensitive method.
- peer-reviewed2018
Schymanski 2018 — Compared formats head to head: single-use PET averaged 14 particles/L, returnable PET 118/L, glass bottles 50/L and beverage cartons 11/L.
Limitation: The glass result is the one people skip. Glass was not zero — particles came from the cap and the filling line, not the bottle wall. Small sample per format.
