DYPER Viscose from Bamboo Diapers
Quick verdict
- Verdict
- Caution
- Evidence
- Moderate
Two DYPER samples were reported non-detect for organic fluorine, a PFAS screening marker; disclosed ECF pulp and an unresolved current-package match keep it in Caution.
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.
- Caution
- Pulp is ECF, not TCF, in the cited manufacturer disclosure.
- Good
- Manufacturer publishes percentage composition.
- Two reported fluorine-screening samples were non-detect.
What we could not verify
- Exact current SKU match and sample identities need completion.
- Exact current package/SKU match should be confirmed.
- Exact current SKU and sample identities need confirmation. The earlier Bureau Veritas attribution is held for source review.
- The canonical record does not substantiate the earlier Bureau Veritas attribution. That claim is held for source review and is omitted from the published testing history; the recorded organic-fluorine non-detect result is not evidence that every PFAS is absent.
Findings awaiting editorial review (1)
- The earlier editorial entry attributed PFAS non-detect results to independent and Bureau Veritas testing.
A manufacturer testing statement is a claim; a fluorine screen is not a targeted PFAS test.
The canonical individual record covers two DYPER organic-fluorine screening samples. Exact current SKU, size and lot matching remains incomplete. The canonical record does not substantiate the earlier Bureau Veritas attribution. That claim is held for source review and is omitted from the published testing history; the recorded organic-fluorine non-detect result is not evidence that every PFAS is absent.
Why we reached this verdict
Bamboo-viscose, OEKO-TEX certified, phthalate-, fragrance-, and lotion-free, with a diaper-composting program. Two DYPER samples were reported non-detect for organic fluorine, a screening marker rather than a targeted PFAS panel. The canonical record gives ppm as the unit but does not state a numerical reporting limit; exact size and lot details still need transcription. Markets as "chlorine free" without claiming "totally"; its disclosed pulp is elemental-chlorine-free (ECF), not TCF, which places it below fully TCF picks under our standard. The current package still needs to be matched to the evidence.

What the evidence shows
BabyGearLab scored Dyper Bamboo 47 of 100 (ranked 14 of 17): absorption 3.3, leakage 3.6, comfort 7.1 and durability 9.0 out of 10. It did not test for PFAS.
Disposable & Cloth Diapers Tested For Indications of PFAS "Forever Chemicals"
Organic fluorine was not detected above the 10 ppm reporting limit on the inside and outside of DYPER Plant-Based & Sustainable Bamboo Diapers, in two tested diapers. Mamavation notes the ECF pulp processing. The page shows an 8/2026 update tag without added comments, so the original test date is taken as 2023.

Materials & ingredients
| 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. |
What's disclosed in our research
| Component | Material | Touches skin? | Function |
|---|---|---|---|
| SAP | Sodium polyacrylate (22%) | No | Absorbency |
| Wood pulp | ECF wood pulp (35%) | No | Absorbent core |
| Paper | Paper (4%) | No | Core/structural material |
| Polypropylene | Polypropylene (9%) | Not recorded | Nonwoven/structural layers |
| Bamboo-derived viscose | Viscose from bamboo (18%) | Yes | Inner/outer cover material |
| Bioplastic | Bioplastic (6%) | Not recorded | Film/structural component |
| Adhesive | Adhesive (2.3%) | No | Assembly/bonding |
| Elastane | Elastane (3.7%) | No | Stretch/fit |
Testing history
| Source | Date | Tested for | Result |
|---|---|---|---|
| Mamavation organic-fluorine screening investigation | Not recorded | Organic fluorine, inside/outside of DYPER diaper samples | Two samples reported non-detect; unit ppm. The canonical record does not state a numerical reporting limit, and exact size and lot details remain incomplete. |
Certifications held
| Certification | What it actually verifies |
|---|---|
| OEKO-TEX Standard 100 | Tests textiles against defined substance and total-fluorine limits for the certified scope; it does not establish that every component of every package generation is PFAS-free. |
