12 Pack: Colgate Floss Mint Waxed Dental Floss – Travel Size, 3 Yards
Lower concern, but wax ingredients aren't disclosed.
Nylon monofilament with wax typically uses paraffin or beeswax, not PFAS-based coatings. Colgate makes no PFAS claims either way.
We flunk more products than we pass. This one earned its grade. How we grade
Material
Nylon monofilament with wax coating
Brand disclosure
Brand is silent on PFAS
Lab data
No public lab test
What’s concerning
Category baseline
PFAS exposure happens more often with clothing products.
No PFAS disclosure
The company has not publicly discussed PFAS in this product.
Nylon monofilament degradation and microplastic shedding
Nylon floss naturally sheds microscopic fibers during use, particularly if the strand frays. The amount is negligible in a single use, but cumulative lifetime ingestion is not quantified in scientific literature; this is a category-wide concern, not specific to Colgate.
What’s reassuring
Safe base material
Made from ceramic, mineral, or natural fiber with no PFAS risk.
Wax coating composition and allergens
Colgate does not disclose the specific wax type (paraffin, beeswax, synthetic) or additives. Standard dental floss wax is food-grade and poses no known toxicity risk, but individuals with severe paraffin or beeswax sensitivity are not catered to by this lack of transparency.
Heavy metals
No recalls or public reports of lead, cadmium, or azo dye contamination in Colgate floss. Nylon is not a typical reservoir for heavy metals, and Colgate is a large multinational with supply-chain oversight, though no third-party testing data is available.
Source: FDA ↗Choking or airway obstruction risk
This is a user-behavior hazard, not a product defect. Dental floss is intended for spitting out after use; swallowing should be avoided, though small incidental amounts are not harmful.
Teflon-type coating (Teflon) presence as alternative risk
Colgate Floss Mint is nylon-based, not Teflon-type coating-based, so thermal fume risk from heating does not apply. Some floss brands use Teflon-type coating; this product does not.
The full breakdown
What it's made of and why it matters
Colgate's floss is nylon monofilament (a single synthetic polymer strand) coated with wax, typically paraffin or beeswax-based. Nylon does not leach harmful compounds into the oral cavity under normal use because floss contact is brief, mechanical, and non-thermal. The wax coating reduces friction and improves handling but is not disclosed in detail by Colgate; standard dental floss wax is food-grade and poses no known ingestion risk in the minimal quantities transferred during use.
The brand's record and disclosure
Colgate-Palmolive has no public recalls or safety warnings specific to their floss products. The company does not publish detailed ingredient or material sourcing disclosures for dental floss, which is typical in the category but limits independent verification. No third-party testing or certification (such as Natural Products Association or EWG) is documented for this product. Colgate maintains general oral-care safety compliance with FDA rules for over-the-counter devices.
How it compares in its category
Nylon monofilament floss is the industry standard and considered chemically safe; alternatives include silk floss (biodegradable but similar chemical profile), charcoal-infused nylon (adds no known hazard), and Teflon-type coating/Teflon-based flosses (see hazard section below). Colgate's waxed version is mid-range in the category, with no distinguishing safety advantage or risk versus other major brands' nylon formulations. Travel-size packaging adds no material safety concern.
If you buy it
Use as directed: gently slide between teeth and along the gum line without forcing. Do not swallow floss; spit it out after use as with all dental floss. The wax coating is safe if small amounts are ingested incidentally during normal use. Store in a cool, dry place; no special handling is needed. Replace the container if the floss becomes frayed or if wax coating degrades visibly, though this is uncommon in a sealed travel pack.
