Public Goods
Public Goods is not a dedicated plastic-free brand - it sells across many categories - but its floss is a genuine plastic-free product: silk thread, candelilla plant wax, refillable glass. It stands out because the floss was independently PFAS-tested (non-detect for organic fluorine in the 2024 Mamavation EPA-certified-lab panel), the kind of third-party verification most brands never publish.
How clear are their specs?
Discloses silk fiber and candelilla-wax coating, and the floss has an independent lab PFAS result to back the claim.
