Public Goods Natural Silk Floss
Silk floss in refillable glass that an independent EPA-certified lab found non-detect for PFAS - the third-party verification almost no floss can point to, at the lowest price of our picks.
The verdict: Plastic-free
A silk thread coated in candelilla wax with peppermint, packaged in a refillable soda-lime glass vial - a fully plastic-free floss, silk being a natural protein fiber that can't be a fluoropolymer. What sets it apart is proof: it was independently PFAS-tested and came back non-detect for organic fluorine in the 2024 Mamavation panel run by an EPA-certified lab. Third-party testing like this is the gold standard - most brands ask you to infer PFAS-free from the fiber, while this one has the lab result to show it.
What it's made of
| Part | Material | Skin contact |
|---|---|---|
| thread | Silk | Yes primary |
| coating candelilla wax + peppermint | Candelilla Wax | No |
| vial | Soda-Lime Glass | No |
A refillable glass floss vial from Public Goods' house line: waxed silk thread dispensed from a small glass jar, with paper-packaged refill spools sold separately. The peppermint-scented candelilla coating gives it grip; the thread is a standard fine silk that works into tight contacts.
