Cocofloss Cocofloss
The honest "eco plastic" case - PFAS-free and part-recycled, but the thick woven thread is still polyester plastic. If you're buying a plastic floss, it's a decent one; it just isn't plastic-free.
The verdict: Mostly plastic
Cocofloss is the honest "eco plastic" trap. On the good side it is genuinely PFAS-free - non-detect for organic fluorine in the 2024 lab panel, and the brand states it contains no PTFE. But the thread is polyester (recycled PET, roughly 85% recycled): recycled or not, that's plastic in the mouth-contact path, so on a plastic-free site it's a corrective rather than a pick. The fair way to hold it: if you're going to buy a plastic floss, at least this one isn't PFAS. The coating is microcrystalline wax plus coconut oil, not a plant wax.
Verification: Manufacturer confirmed
What it's made of
| Part | Material | Skin contact |
|---|---|---|
| thread recycled PET, ~85% recycled | Polyester | Yes primary |
A thick, textured, woven floss with a cult following in dental offices - the many-filament weave holds more of its wax-and-coconut-oil coating and scrubs wider surfaces than a thin monofilament. Sold in refillable metal dispensers with spool refills.
Pros
- PFAS-free - non-detect for organic fluorine in independent testing, and no PTFE
- Thick woven texture holds coating well and cleans wide contact surfaces
- Uses largely recycled PET rather than virgin plastic
Cons
- The thread is still polyester plastic in the mouth-contact path
- Coated in petroleum-derived microcrystalline wax, not a plant wax
- Priced like a premium floss despite being a plastic thread
