How we evaluated it
Why we chose it What put it on our list
- In a lab screen of 39 floss products by Mamavation and Environmental Health News (first published in 2022, updated in 2024), Cocofloss “Delicious Mint,” which we take to be this flavor, had no detectable organic fluorine, a marker for PFAS. Oral-B Glide Pro-Health measured 248,900 ppm.
- The maker says “non-PTFE with no added PFAS,” BPA-free, vegan and Leaping Bunny cruelty-free.
- The page states what it is made of: 500 or more woven polyester fibers, 85% recycled material, infused with coconut oil and microcrystalline wax.
- Refills are about $9 and fit any Cocofloss dispenser, which cuts the plastic from the dispenser.
Trade-offs What to weigh before you buy
- It is a plastic floss. The fibers are polyester, which is not on the category’s list of silk, plant-based or nylon floss. The maker says silk and other natural materials lack the efficacy it requires.
- Microcrystalline wax is usually petroleum-derived. The page does not say where this one comes from, or what the mint flavor is.
- About $10 for 33 yards costs more than ordinary floss. The lab result is one sample in a screen for total organic fluorine, not a test for named PFAS.
- The Mamavation article that reports the result also carries a Cocofloss discount code, so the outlet has a commercial tie to this brand.
What to know Details worth knowing first
Cocofloss is woven from hundreds of fine polyester fibers that spread out between the teeth, with coconut oil and a wax for slip. It is not silk and it is not a “glide” floss. The page says it is non-PTFE with no added PFAS, and a consumer lab screen agrees: no detectable organic fluorine. Our guide to avoiding PFAS explains why PTFE-coated floss is the one to skip.
Silk works for many people but can shred on tight teeth, which is the usual reason to try a woven floss. The trade is plastic. The maker says 85% of the material is recycled, and refills cut the dispenser waste, but the floss is still polyester. For the wider picture, see reducing microplastics.
Treat the lab result as a good sign, not a guarantee. It is one sample from one test. Mamavation listed the flavor as Delicious Mint and the maker’s page says Delightful Mint, so we assumed it is the same formula.
Quality & testing How it measures up against our checklist
- Third-party tested
- Yes
- Tested by
- Mamavation and Environmental Health News (EPA-certified lab, name not given)
| What we checked | What we found |
|---|---|
| PFAS-free floss Verified | No detectable organic fluorine in one sample of Cocofloss Delicious Mint in Mamavation’s screen (first published in 2022, updated in 2024). The maker says non-PTFE with no added PFAS. |
| Every ingredient listed Maker’s claim | The page names polyester fibers, coconut oil and microcrystalline wax. The flavor is not described. |
| Honest claims Not verified | The page says “removes 4x more plaque than a leading floss” and “#1 dentist-recommended woven floss” (an IQVIA survey). We could not see either test. |
What the labels mean
- Verified We opened an independent record that confirms it: a certifier’s listing, a regulator’s list or a lab report. It is linked under Sources.
- Maker’s claim The maker says so on its own page or label. We read it but found no independent record.
- Not verified We looked and could not confirm it, or the maker does not say. Treat it as unknown.
