Dental Floss - 160 meter Dispenser Vial by Procter & Gamble - Glide-Floss - Shred Resistant - Wax Coated

F · High PFAS

Skip until clarification, waxed dental floss often uses PFAS-based water/stain repellents, and this brand discloses nothing.

Glide-brand dental floss is marketed as wax-coated and shred-resistant, but the specific wax formulation and coating chemistry are undisclosed. Dental floss, especially waxed varieties, has historically contained PFAS for water and stain resistance.

What we don’t know

This grade is a model-based estimate from public materials, coatings, and brand disclosure at 42% 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.
