Elmex Waxed Dental Floss 50m
Lower concern. Dental floss carries minimal PFAS risk.
Elmex waxed dental floss is nylon-based with wax coating. No PFAS disclosures found, but dental floss category poses lower ingestion/bioaccumulation risk than cookware or textiles.

What Elmex Waxed Dental Floss 50m is made of, ingredients and materials
Elmex Waxed Dental Floss is nylon fiber (likely polyamide 6 or 6,6) coated with wax, typically paraffin or beeswax blends. Nylon is chemically inert at room temperature and does not leach significant compounds during the brief, low-moisture contact of flossing. The wax coating serves to reduce friction and improve glide between teeth, and is not ingested in meaningful quantity. This material combination has lower concern compared to other options in the oral care category.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Fragrance allergens (if flavored variant)
Unflavored Elmex Waxed Floss carries minimal fragrance risk. Flavored variants (e.g., mint) may contain fragrance compounds; these are permitted in oral care but can trigger sensitivity in rare individuals with fragrance allergies. Check product label for flavor declarations.
Microplastics
Nylon fibers can fragment during use; small pieces may be swallowed incidentally. The total mass is negligible (milligrams per year of use), and nylon microplastics are not absorbed in the GI tract. This is a minor environmental concern, not an acute health hazard.

Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Wax composition and ingestion hazard
Paraffin and beeswax are food-grade, non-toxic substances when ingested in trace amounts. Elmex does not disclose wax type or additives; standard commercial paraffin wax carries no established oral toxicity at the micrograms-per-use exposure of flossing.
Synthetic dyes in nylon
Nylon fiber in this product is likely undyed or colored with approved colorants. No azo dyes or heavy metal pigments are expected in dental floss formulations under current regulation. No recalls or adverse events on record for Elmex floss color additives.
Nylon monomer residues (caprolactam)
Polyamide 6 nylon can release caprolactam monomer under elevated temperature or prolonged contact with lipids. Oral flossing occurs at body temperature (37C) with minimal lipid exposure; theoretical residual monomer is below oral-ingestion concern thresholds per EFSA assessments.
The full breakdown
The brand's record and disclosure
Elmex (owned by CP Pharma, a Colgate subsidiary) maintains established safety standards for oral care products and complies with EU and FDA cosmetic regulations. The brand does not publicly disclose detailed ingredient sourcing or PFAS testing, but nylon floss is not a known source of regulatory concern for Elmex products. No significant safety recalls or controversies specific to Elmex floss are on record. The brand's parent company has faced scrutiny on broader environmental and chemical transparency, but Elmex floss itself carries no established black mark.
How it compares in its category
Nylon waxed floss is the dominant category standard and generally considered lower-risk than flavored varieties (which may contain fragrance allergens or synthetic colorants). Unwaxed floss and Teflon-type coating-coated alternatives (like Teflon) are also commonly available; Teflon-type coating carries theoretical thermal decomposition risk if accidentally heated, whereas nylon-wax does not. Silk floss is marketed as a natural alternative but offers no meaningful safety advantage and may carry pesticide residues if not certified organic. Elmex's formulation represents mainstream practice with no distinguishing hazard profile.
If you buy it
Store floss at room temperature, away from direct heat and moisture, to preserve wax coating integrity. Do not heat, chew, or ingest the floss intentionally; swallow only trace amounts incidental to normal flossing. Replace the spool if wax coating visibly degrades or floss shreds, as this reduces efficacy and may indicate material breakdown. Flossing daily for 30-60 seconds per interdental space is a common practice; no hazard of this kind on record for nylon-wax floss.
