Lower concern, caveats Assessed 25 Jul 2026 · 2 months ago

Assessed from partial disclosure — some materials unconfirmed.

Microplastic Status

We could not fully establish everything Smol Laundry Capsules is made of, or its materials (PVOH (PVA) dissolvable film, plant-derived surfactants, enzymes, oxygen bleach) sit in a class where the published evidence is genuinely mixed. "Lower concern, caveats" is not a signal that the product does shed microplastics — it means we could not get far enough to say that it does not.

How we assess products

We work from published information; we do not lab-test, and a verdict here is never a claim that we have.

About This Product

Based on Smol's published ingredient information, the cleaning agents are plant-derived and Smol states the capsules contain no microplastic ingredients. The capsule film is polyvinyl alcohol (PVOH) — a water-soluble synthetic polymer. The EU microplastic restriction exempts polymers that dissolve, but the ASA has ruled that exemption is not itself evidence a film is plastic-free, and its environmental fate is unresolved — hence lower concern, caveats.
