Reach Dental Floss Waxed
Lower-concern dental product; no known PFAS risk, but brand silence leaves room for uncertainty.
Reach Waxed Dental Floss is a nylon filament product with wax coating, neither material class typically associated with intentional PFAS use. Dental floss has not emerged as a documented PFAS exposure vector in public health literature.

The full breakdown
What it's made of and why it matters
Reach Waxed Dental Floss is a nylon monofilament or multifilament strand coated with wax (typically paraffin or beeswax-based). Nylon is a synthetic polymer with no known leaching of monomers or plasticizers under the low-moisture, low-temperature conditions of oral use. The wax coating serves only a mechanical function (glide and durability) and is not systemically absorbed; any swallowed floss fragments are inert and pass through the digestive tract unchanged.
The brand's record and disclosure
Reach is owned by Johnson & Johnson and is a legacy oral care brand with a long market history. The brand does not publicly disclose detailed material sourcing or independent safety certifications for floss products. No recalls specifically targeting chemical hazards in Reach floss are on record. The brand's silence on PFAS does not necessarily indicate use; standard dental floss formulations do not require PFAS, and no credible testing has flagged conventional nylon floss as a PFAS vector.
How it compares in its category
Waxed nylon floss is the dominant category globally and carries no higher chemical risk than unwaxed variants or alternatives like polytetrafluoroethylene (Teflon-type coating) tape. Some premium brands offer silk floss or plant-based waxes, but safety data does not show meaningful advantage over nylon-paraffin. Reach's formulation is conventional and poses no distinct hazard relative to Oral-B, Colgate, or store-brand equivalents.
If you buy it
Dental floss is not ingested; swallowing small fragments or traces of wax during normal flossing is inconsequential. Replace the spool if the filament becomes frayed, shredded, or loses structural integrity, as degraded floss is less effective and may lodge between teeth. No special storage, heat exposure, or maintenance is required. Use once daily or as directed by your dentist; there is no cumulative exposure concern from routine use.
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 composition (paraffin vs. alternative)
Reach does not publicly specify wax type. Paraffin wax is food-grade and non-toxic; if any alternative wax is used, no published data links it to oral or systemic toxicity from trace ingestion during flossing.
Nylon monomer (caprolactam) leaching
Nylon filament does not leach caprolactam under oral pH and temperature. No case reports or testing suggest migration into saliva from dental floss during normal use.
Microplastic or filament fragmentation
Aggressive or repeated flossing can cause nylon filaments to fray and shed microscopic fragments. Total exposure is minimal and occurs in the mouth (not swallowed systematically); clinical significance is unknown but not documented as a concern in dental literature.
Dyes or pigments in colored floss variants
If Reach offers colored floss, no heavy-metal dyes or azo dyes are commonly reported in dental floss products. FDA does not regulate floss dyes as strictly as cosmetics, but no known incidents link Reach floss color to toxicity.
Bacterial colonization of spool or packaging
Reach floss is supplied in sealed, single-use spools and does not require maintenance. No special storage concerns; normal bathroom conditions do not promote mold or bacterial growth on the floss itself.
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.
