Plackers Twin-Line Dental Flossers
Lower-concern choice; standard dental floss unlikely to contain PFAS, but brand provides no transparency.
Plackers Twin-Line Dental Flossers are nylon floss with a plastic handle, materials not typically associated with intentional PFAS use. No public evidence of Teflon-family coating coatings, water-repellent treatments, or PFAS-related recalls.

Why this grade
Category baseline

No PFAS disclosure
No public statement about PFAS in this product.
Safe base material
Made from a material with no inherent PFAS use (ceramic, mineral, or natural fiber).
The full breakdown
What it's made of and why it matters
Plackers Twin-Line uses nylon monofilament floss wound on a plastic handle, typically polystyrene or similar rigid thermoplastic. Nylon is chemically stable and does not leach into the mouth during normal use because flossing is brief contact with saliva, not heat or extended immersion. The plastic handle is not ingested and poses no leaching risk under typical use conditions.
The brand's record and disclosure
Plackers is owned by Edgewell Personal Care and has no public safety certifications or transparency initiatives specific to chemical composition. No recalls or safety controversies are on record for this product line. The brand does not publicly disclose PFAS testing or avoidance, consistent with broader industry silence on dental floss chemical profiles.
How it compares in its category
Dental floss products are among the lowest-risk personal care items because they involve minimal ingestion and no heating. Plackers Twin-Line sits at the mainstream middle of the category: functional, widely available, and without documented hazard reports. Alternatives like silk floss, waxed nylon, or plastic picks carry equivalent or slightly higher unknown-hazard profiles due to less established material histories.
If you buy it
Store in a dry place to prevent mold growth on the handle if left damp. Replace the flosser every 1-2 weeks or when the nylon becomes frayed or loses tension, as degraded floss is less effective and may splinter. No special heating restrictions apply. The product requires no maintenance beyond occasional rinsing under water.
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.”
Nylon microfiber shedding
Worn or frayed nylon floss may shed microscopic fibers into the mouth, but ingestion of trace amounts is not documented as a health concern in dental floss literature. Replacement of worn flossers minimizes this theoretical risk.
Plastic handle degradation and off-gassing
The polystyrene or similar handle is not heated and is never ingested, so off-gassing of VOCs into the mouth is not a documented issue for this product class. No safety reports link dental flosser handles to chemical exposure.
Bacterial colonization on reusable handle
The plastic handle is wet repeatedly and stored in bathroom conditions, creating conditions for mold or bacterial growth if not dried. Regular rinsing and air-drying reduce this risk; replacement every 1-2 weeks prevents long-term colonization.
Colorants or dyes in nylon or handle
Plackers Twin-Line floss and handles are dyed for visibility, but azo dyes and heavy metal pigments are not on record as concerns in dental floss products. The brief, low-contact nature of use makes dermal or ingestion exposure extremely unlikely.
Formaldehyde or resin residues in nylon
Nylon floss is not treated with antimicrobial formaldehyde-release resins or ceramic coatings, as are some textiles or cookware. Industrial nylon production does not leave residual formaldehyde under normal circumstances.
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.
