Naty (formerly Eco by Naty) BioEmbrace Diapers
Quick verdict
- Verdict
- Caution
- Evidence
- Limited
OEKO-TEX certified, plant-based, fragrance-free (the predecessor Eco by Naty line tested non-detect for organic fluorine, not yet independently confirmed for current BioEmbrace), plus a recent switch from TCF to ECF pulp keeps it out of verified.
Check the package version: the research does not yet confirm an exact match to every current product. See version details.
- Current BioEmbrace differs from historical Eco by Naty; historical test evidence cannot be silently carried forward.
- Caution
- Historical PFAS-related testing belongs to the old Eco by Naty generation, not automatically to BioEmbrace.
- Good
- Current BioEmbrace construction materials are disclosed at a useful component level.
What we could not verify
- Current BioEmbrace-specific independent fluorine/PFAS testing not yet established in this record.
- Current BioEmbrace differs from historical Eco by Naty; historical test evidence cannot be silently carried forward.
Why we reached this verdict
Swedish brand, OEKO-TEX certified, plant-based topsheet, fragrance- and lotion-free, and the least expensive of the genuinely clean picks in this category. The predecessor Eco by Naty line tested non-detect for organic fluorine (a PFAS marker); that result hasn't been independently confirmed for the current BioEmbrace formulation. Recently switched its pulp from TCF to ECF, which is the specific reason it sits in caution rather than verified, the chemistry is otherwise clean, but the switch is a real step down under our standard, not a marketing nitpick.

What the evidence shows
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 Eco by Naty Size 2 and Size 5 diapers. These are the predecessor Eco by Naty product, not the current BioEmbrace, and the page notes the brand recently switched from TCF to ECF pulp.
BabyGearLab scored Eco by Naty 65 of 100 (ranked 8 of 17): absorption 9.7, leakage 5.8, comfort 2.7 and durability 1.0 out of 10. This reviews the predecessor line and did not test for PFAS.

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 | Recently switched its pulp from TCF to ECF, a real, disclosed step down under our standard that keeps this in caution rather than verified, even though the rest of the chemistry is clean. |
What's disclosed in our research
| Component | Material | Touches skin? | Function |
|---|---|---|---|
| Topsheet/liner | Plant-based polyethylene | Yes | Skin-contact liner |
| Leg cuffs | Elastomer covered by plant-based polyethylene | Yes | Leak control / fit |
| Ears | Plant-based polyethylene | No | Fastening/fit |
| Absorbent core | FSC cellulose + sodium polyacrylate (SAP) | No | Absorbency |

Testing history
| Source | Date | Tested for | Result |
|---|---|---|---|
| Independent lab testing (predecessor Eco by Naty line) | Not recorded | Organic fluorine (a PFAS marker), not independently retested for current BioEmbrace | Non-detect |
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. |

Evidence assessment & uncertainty
Technical detail: Evidence assessment & uncertainty
- Positive Attributes
- Current BioEmbrace construction materials are disclosed at a useful component level.
- Important Concerns
- Historical PFAS-related testing belongs to the old Eco by Naty generation, not automatically to BioEmbrace.
- Uncertainties
- Current BioEmbrace-specific independent fluorine/PFAS testing not yet established in this record.
- Unverified Claims
Formulation verification
The current package still needs to be matched to this evidence because: Current BioEmbrace differs from historical Eco by Naty; historical test evidence cannot be silently carried forward.
