Dental Floss Freshmint 12 Yard Mint Flavor | getMovility
Lower PFAS concern for a standard nylon dental floss product; no red flags identified.
Euthymol Freshmint dental floss is a traditional nylon-filament product with no disclosed PFAS-related treatments. Dental floss typically uses wax or coating for texture but rarely requires water-repellency or stain resistance that would warrant PFAS. The brand makes no PFAS claims either way, which is standard for this category.

The full breakdown
What it's made of and why it matters
This product is nylon filament, likely monofilament or twisted strands, coated with wax and mint flavoring compounds. Nylon is a synthetic polymer that does not leach or degrade in the oral cavity under normal use. The wax coating (typically beeswax, paraffin, or plant-based) is inert and approved for food contact. Mint flavoring is a minor additive (menthol and related terpenes) at concentrations far too low to cause systemic exposure during brief daily flossing.
The brand's record and disclosure
Euthymol is a heritage UK oral care brand without publicly documented safety controversies or major recalls related to dental floss. The brand does not make prominent PFAS disclosures, which is typical for the dental floss category where PFAS use is not standard practice. No independent certifications (e.g., EWG Verified, Cradle to Cradle) are noted for this specific product, but absence of certification does not indicate a hazard.
How it compares in its category
Nylon dental floss is the industry standard and is chemically safer than older silk floss (which can harbor bacteria if contaminated). Waxed nylon floss like this sits midrange in the category; it is equivalent to major brands (Oral-B, Glide) in material safety. Some consumers prefer unwaxed nylon or plant-based alternatives (silk, bamboo) for environmental reasons, but safety profiles are comparable. Flavored variants are common and do not carry additional toxicity risk.
If you buy it
Use daily without concern for material toxicity; the product is designed for brief oral contact. Store in a cool, dry place to prevent wax breakdown, though this affects performance (slipperiness) rather than safety. Replace the spool when floss becomes frayed or loses effectiveness, typically every 1 to 3 months with normal use. Mint flavoring may irritate sensitive gums in rare cases; if so, switch to unflavored nylon floss.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Flavoring allergens (mint/menthol)
Menthol and mint extracts can trigger contact sensitivity or irritation in individuals with oral mucosa inflammation or menthol allergy. This is rare but documented in the dermatological literature for topical menthol exposure.
Wax coating degradation or contamination
Nylon dental floss wax (paraffin or beeswax) is food-safe and does not degrade under normal mouth pH and temperature. No recalls or adverse events are on record for Euthymol or comparable waxed nylon floss.
Nylon microparticles
Nylon filament does not fragment into microplastics under normal flossing forces; the material is designed to be strong and non-fraying. No evidence exists that dental floss contributes meaningfully to microplastic ingestion.
Ingestion of trace ingredients (wax, flavoring)
Minute amounts of wax and flavoring may be swallowed during flossing. All ingredients (paraffin, beeswax, menthol) are food-grade and cleared for incidental ingestion at these trace levels by regulatory bodies (FDA, EFSA).
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
