What diapers are safe? Here’s Our Verdict

DYPER Viscose from Bamboo Diapers

Caution$

Last reviewed September 16, 2026

Quick verdict

Published composition and two non-detect screens are useful, but the disclosed pulp is ECF.

Check the package version: the research does not yet confirm an exact match to every current product. See version details.

Exact current package/SKU match should be confirmed. See the full research below.

Good / Caution / Avoid

Caution: The cited manufacturer disclosure specifies ECF pulp, not TCF.
Exact current product and tested-sample matching remains incomplete.
Good: Manufacturer publishes percentage composition.
Two reported fluorine-screening samples were non-detect.

Read the original editorial assessment

Verdict: Caution. Current package matching remains unresolved; read the newer evidence below.

Bamboo-viscose, OEKO-TEX certified, phthalate-, fragrance-, and lotion-free, with a diaper-composting program. Tested non-detect for PFAS twice, including DYPER's own Bureau Veritas testing. Markets as "chlorine free" without claiming "totally" — it's an elemental-chlorine-free (ECF) product, not TCF, which is why it sits a tier below the fully TCF picks under our standard even with no other issues found.

Price tiers are relative within this category and may change over time.

Materials & ingredients

Factors flagged in the editorial review. Expand the research below for full formulation records, functions and sources.

Material or ingredient	What it is	Concern level	Why it's flagged here
Elemental chlorine-free pulp	Most disposable diapers use a wood-pulp fluff core for absorbency, and that pulp has to be bleached bright white during manufacturing.	Depends on context	Markets as "chlorine free" without claiming "totally" — an ECF, not TCF, product. ECF is acceptable under our standard, not disqualifying, but it sorts a tier below fully TCF picks.

Final verdict against our diapers standard

This is the published editorial verdict. Read the formulation caveats and working research above; the imported evidence has not automatically re-scored this product.

Caution Published as Caution under the published standard for diapers, based on the specific, dated findings above.
