Cocofloss · Dental Floss
Cocofloss Mini, 8 yd — 40 Pack
Lower PFAS concern for standard dental floss; no evidence of Teflon-family coating or water-resistant treatment typical of high-risk categories.
Cocofloss Mini is a basic dental floss product with no public disclosure of PFAS-containing coatings or treatments. Dental floss typically does not require water-resistant or non-stick treatments that would trigger PFAS use.

The full breakdown
What it's made of and why it matters
Cocofloss Mini is a nylon-based dental floss, a common food-grade polymer used in oral care for over 70 years. Nylon is chemically inert at mouth temperature and does not leach known endocrine disruptors or heavy metals during normal use. The 8-yard format and mini size suggest this is a standard waxed or unwaxed nylon filament with minimal additives beyond slip agents and minor colorants.
The brand's record and disclosure
Cocofloss (owned by Environmental Mouth & Body) markets itself as a sustainability-focused oral care brand but provides limited public transparency on material sourcing, manufacturing location, or third-party certifications. No recalls, safety warnings, or documented complaints specific to Cocofloss floss are on record with the FDA or consumer safety databases. The brand does not publicly disclose PFAS testing or use, consistent with industry silence on this issue.
How it compares in its category
Standard nylon floss is the category baseline and carries no known chemical hazards beyond those of generic plastics. Cocofloss positions itself as more eco-conscious than conventional brands (e.g., Oral-B, Colgate) but offers no material safety advantage; the product safety profile is equivalent. Silk floss alternatives pose identical use-safety but may cost more and biodegrade faster.
If you buy it
Store in a cool, dry place away from direct sunlight to prevent minor discoloration of packaging. Use daily as directed; nylon floss is mechanical and requires no heat exposure or special handling. Replace the container every 2-4 weeks depending on frequency of use. No special precautions are needed; this is standard oral care with no known usage restrictions.
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 degradation and microplastic shedding
Nylon floss can shed microscopic fibers during aggressive flossing or if the filament frays; no published data on Cocofloss specifically, but nylon-based oral products are mechanically prone to this. The amount and impact of any fibers swallowed daily is considered negligible by dental authorities.
Colorant or slip-agent allergens
Cocofloss does not publicly disclose dyes, waxes, or surfactants used in manufacturing. Standard dental floss colorants (azo dyes, titanium dioxide) are food-contact approved, but no specific testing or ingredient list for this product is available.
Heavy metals in nylon resin
Food-grade nylon used in oral care is manufactured under FDA oversight and does not require heavy metal testing at point of sale, as ingestion risk is minimal and nylon is inert. No recalls or alerts for lead, cadmium, or other metals in dental floss exist.
Antimicrobial additives or triclosan residue
Cocofloss marketing does not mention antimicrobial treatments. Standard dental floss does not contain triclosan or other regulated antimicrobials; this product appears to be simple nylon or silk without chemical additives for antimicrobial effect.
Wax coating safety (if present)
If waxed, the coating is typically food-grade paraffin, beeswax, or candelilla wax, all safe for oral use and non-toxic if swallowed. Cocofloss does not disclose wax type, but no hazard reports exist for this product line.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 78% 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.
