2pk 100 + 12yds PEPSODENT DENTAL FLOSS MINT-24
Lower concern, standard nylon floss carries minimal PFAS risk.
Pepsodent dental floss is a simple nylon product with no known Teflon-family coating coatings or water-repellent treatments typical of PFAS sources. The brand makes no PFAS claims either way. Dental floss is not a typical PFAS vector; standard nylon formulations pose lower concern than stain-resistant or waterproof-treated goods.

The full breakdown
What it's made of and why it matters
Pepsodent dental floss is nylon monofilament or multifilament coated with wax (typically paraffin or similar) and mint flavoring agents. Nylon is a thermoplastic polymer that does not leach monomers or plasticizers into the oral environment during normal use, since floss spends only seconds in contact with saliva and is not heated. The wax coating serves to ease passage between teeth and does not present ingestion risk at the trace amounts involved in flossing.
The brand's record and disclosure
Pepsodent is owned by Unilever, a multinational with established safety and regulatory compliance programs. The brand does not publicly disclose detailed composition or third-party testing results for this floss product, which is typical for dental floss manufacturers. No product recalls or safety violations for this specific floss line are on record. Unilever maintains general commitments to ingredient safety but does not independently publish certification for dental floss products.
How it compares in its category
Dental floss is one of the lowest-risk oral care products; nylon floss is the standard and safest formulation compared to alternatives like silk or Teflon-type coating. Pepsodent's offering is conventional and carries no distinctive safety advantage or disadvantage versus generic nylon floss from other major brands. Mint flavoring is a common additive in this category and poses no known toxicity at typical use levels. Price and packaging (2-pack) suggest this is a mass-market product with standard formulation.
If you buy it
Use as directed: short lengths between teeth, no swallowing. Floss does not require maintenance or special storage beyond keeping it dry to prevent mold in humid bathrooms. Replace the spool when depleted or if wax coating visibly degrades or frays; this typically occurs after 2-4 months of regular use. Mint flavoring is safe to swallow in the minute quantities present on floss, but floss itself should not be ingested.
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.”
Synthetic polymer ingestion (nylon)
Nylon is inert in the gastrointestinal tract and passes through undigested if accidentally swallowed; no toxicity or microplastic concern established for floss use.
Wax coating safety
Paraffin wax and mineral oil wax coatings are food-grade and pose no documented risk at the microscopic residue left on teeth after flossing.
Mint flavoring and additives
Mint flavoring in dental products is standard and non-toxic at typical exposure levels; no formaldehyde, azo dyes, or heavy metal contamination has been reported for Pepsodent floss.
Talc or silica powder residue
Dental floss typically does not include talc or silica powder on the strand; only wax coating is present, eliminating inhalation or aspiration risk.
Fragrance allergens
Mint flavoring can trigger oral or throat irritation in individuals with severe menthol sensitivity or mint allergy, though this is rare; discontinue if localized irritation occurs.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 78% 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.
