Perioe · Dental Floss
Dr. Collins Dental Work Floss Mint Waxed 50 Meter Package
Lower concern; conventional waxed floss rarely uses PFAS, but coating details warrant clarification.
Standard waxed dental floss carries lower PFAS risk than coated cookware or stain-resistant textiles, wax coatings typically do not require Teflon-family coating. However, the brand provides no transparency on coating composition. For maximum assurance, contact Perioe directly about their specific wax type.

The full breakdown
What it's made of and why it matters
This product is nylon floss coated with wax, a standard dental hygiene formulation. The wax coating (type unspecified on packaging) serves to reduce shredding and ease insertion between teeth. Nylon itself is inert in the oral cavity; the safety question centers on what wax is used and whether it contains additives like plasticizers or unintended contaminants. Mint flavoring is typically a food-grade additive applied to the wax surface.
The brand's record and disclosure
Perioe (a South Korean oral care brand under Amore Pacific) maintains low public visibility in Western markets and provides minimal ingredient transparency on this product. No major recalls or safety controversies linked to their dental floss have been documented in public records. The brand does not publish detailed composition data for wax type or additive sourcing, which limits independent verification of safety claims.
How it compares in its category
Waxed nylon floss is the market standard and represents the safest conventional choice relative to unwaxed or tape alternatives. This product aligns with typical commercial offerings from brands like Oral-B and Crest; no material performance advantages or disadvantages are evident from available information. The 50-meter spool is a common retail size with average expected usage duration of several weeks to months.
If you buy it
Use as directed: wind floss around fingers, guide between teeth with gentle sawing motion, and dispose after use. Do not ingest; floss is designed for mechanical cleaning only and should not be swallowed in quantity. Replace the spool if wax coating visibly degrades or frays excessively. Store in a cool, dry location to prevent wax softening or mold growth on the spool.
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.”
Wax coating unknown composition
Perioe does not specify whether wax is paraffin, beeswax, or synthetic; paraffin-based coatings may contain trace mineral oil residues, though oral ingestion of floss is incidental and minimal.
Mint flavoring allergen potential
Menthol or mint oil additives can trigger contact dermatitis or oral mucosal sensitivity in susceptible individuals; risk is low but present with daily use in the oral cavity.
Microplastic shedding
Nylon floss does not shed microplastics during normal use; fiber fragments are mechanically cleaned away and do not accumulate in tissue.
Dye or color additive toxicity
No color additives are present in typical waxed nylon floss; mint variant uses only food-safe flavoring agents with no established oral safety concerns in trace amounts.
Choking or GI obstruction risk
Floss is not intended for ingestion; accidental swallowing in small quantities poses negligible risk, but deliberate or repeated ingestion could theoretically cause blockage in vulnerable populations (young children, pets).
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 62% 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.
