Dr. Collins Perio Pro Floss Mint Waxed 150m
Lower PFAS concern for dental floss; no known PFAS triggers, but brand offers no transparency.
Dental floss with wax coating typically uses non-Teflon-family coating waxes (carnauba, beeswax, or paraffin). No public evidence links this product to PFAS. However, Perioe does not disclose coating materials or make PFAS-free claims, leaving some ambiguity about wax source and additives.

The full breakdown
What it's made of and why it matters
Dr. Collins Perio Pro is a nylon monofilament floss coated with wax, typically paraffin or beeswax blend. Nylon is chemically stable in the mouth and does not leach into saliva under normal use conditions. The wax coating reduces fraying, aids gliding between teeth, and poses negligible ingestion risk since floss is not swallowed in meaningful quantities. Mint flavoring is typically food-grade and applied topically to the wax layer.
The brand's record and disclosure
Perioe is a South Korean oral care manufacturer with no widely documented safety recalls or chemical disclosure controversies on record for this product line. The brand does not publicly disclose material sourcing, third-party certifications, or PFAS testing results, reflecting a broader silence in the dental floss category on these issues. No substantive safety incidents have been reported in clinical or consumer databases for this specific product.
How it compares in its category
Waxed nylon floss represents the mainstream category standard alongside other nylon and Teflon-type coating alternatives. This product sits in the mid-tier in terms of transparency; many mainstream brands (Oral-B, Colgate, Listerine) offer similar material profiles without enhanced disclosure. Unwaxed floss and water flossers present no material advantage in chemical safety, though they serve different mechanical preferences.
If you buy it
Store in a cool, dry place away from direct sunlight to preserve wax integrity. Do not heat or expose to temperatures above 50C. Replace the roll if fraying increases or mint flavor fades, indicating wax degradation. Use standard oral hygiene practices; swallow no significant floss length and discard after 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.”
Synthetic dye or colorant in wax coating
Mint-flavored waxed floss typically uses food-grade colorants in the wax layer. No toxicological data or recalls specific to Dr. Collins Perio Pro indicate problematic dyes; standard regulatory oversight in oral care products applies.
Wax coating degradation and ingestion
If floss is frayed or brittle, small wax particles may be ingested during use. While paraffin and beeswax are food-safe at trace levels, chronic ingestion of floss fragments is not normal use and should be avoided by replacing degraded rolls promptly.
Mint flavoring allergens or irritants
Mint oil and mint extract are common in oral care and generally recognized as safe for the oral mucosa. No specific allergic reactions or irritation incidents are documented for this product; individuals with menthol sensitivity should patch-test or switch to unflavored alternatives.
Nylon microparticle shedding
Nylon fibers can shed microscopic fragments during normal flossing, particularly if floss is worn or degraded. Ingestion of trace nylon particles occurs but is not established as a health hazard in the scientific literature; systemic accumulation risk is considered minimal for this use case.
Bacterial growth on stored floss
Dental floss containers can harbor oral bacteria if not kept dry or if exposed to moisture and warmth. This is a hygiene concern for the product storage, not the floss material itself; standard dry storage mitigates this risk.
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.
