Cocofloss Cocofloss

Not recommended

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.

We don't recommend this one

Genuinely PFAS-free and eco-branded, but the thread is still polyester plastic (recycled PET). If you want a floss with no plastic in the contact path at all, choose a silk pick like Dental Lace or Public Goods.

The verdict: Significant plastic contact

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.

What it's made of

PartMaterialSkin 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

  • 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
