Colgate Total Dental Floss, Mint Flavor, Travel Size 3 Yards, Waxed Glide Floss for Plaque Removal Between Teeth and Along Gumline, Compact Pocket

Excellent

Lower concern, yet brand transparency on PFAS is missing.

Verdict: BuyStandard nylon dental floss with minimal established hazards; no brand transparency issues unique to this product.

Standard waxed nylon floss doesn't typically require PFAS, and no red flags exist. The brand hasn't disclosed its PFAS stance or testing.

Material

Nylon floss 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.

80/ 100
♾️

No PFAS disclosure

The company has not publicly discussed PFAS in this product.

85/ 100
🫧

Nylon degradation and microplastic generation

Nylon fibers can shed microscopic particles during aggressive flossing. Ingestion of these particles occurs naturally but cumulative exposure over years remains unstudied in humans; the practical significance is unknown but represents a non-zero environmental and physiological exposure route.

70/ 100

What’s reassuring

Safe base material

Made from ceramic, mineral, or natural fiber with no PFAS risk.

100/ 100

Wax composition and purity

Colgate does not disclose whether wax coating is food-grade or pharmaceutical-grade paraffin, beeswax, or a blend. No contaminant testing or impurity reports are publicly available for this product line, but nylon floss wax is swallowed in minute quantities during normal use and poses minimal acute risk.

95/ 100

Mint flavoring agents

Mint flavoring compound is not specified. Natural or synthetic menthol and other flavor oils are standard in dental floss and are not designated as hazardous in oral care products; allergic sensitization is rare but possible in individuals with specific fragrance sensitivities.

95/ 100

Bacterial colonization of floss material

Nylon and wax are not known substrates for pathogenic biofilm growth during single-use application. Reusing floss (not recommended) or storing damp floss increases mold and bacterial risk, but this reflects misuse, not product design.

95/ 100

Gum trauma from improper use

Floss itself carries no chemical hazard, but mechanical injury to gums is user-dependent. Aggressive insertion, excessive pressure, or pre-existing gum disease can cause bleeding or recession; this is a technique issue, not a material safety issue.

95/ 100

The full breakdown

What it's made of and why it matters

Colgate Total Dental Floss is nylon filament coated with wax (composition unspecified by Colgate, typically paraffin or beeswax). Nylon is a synthetic polymer chosen for strength and glide; the wax reduces friction and helps the floss slip between teeth without shredding. No adhesives, plasticizers, or reactive compounds are typically present in basic dental floss formulations, making the material profile straightforward and low-risk during normal oral use.

The brand's record and disclosure

Colgate does not publish detailed material safety data sheets or ingredient sourcing for dental floss products. The brand has faced recalls on other oral care products (notably toothpaste in certain markets for microbial contamination) but no documented safety recalls on this floss line. Colgate maintains ISO and FDA compliance certifications for dental products but offers no third-party testing transparency specific to floss formulations.

How it compares in its category

Waxed nylon floss is the most common category segment globally and is considered a commodity product with minimal differentiation in safety profile. Alternatives include unwaxed nylon, silk, and plant-based fibers; none carry established safety advantages over waxed nylon for typical users. Colgate's travel size and mint flavoring are convenience features, not safety considerations, and fall within standard formulation ranges for major brands.

If you buy it

Use as directed: unwind 12-18 inches, wrap around fingers, and guide gently between teeth using a sawing motion. Mint flavoring is cosmetic and poses no ingestion risk in normal use; discard floss after single use and do not reuse. Replace the 3-yard travel pack when depleted; no storage precautions beyond keeping dry are needed. If gums bleed excessively or become inflamed, consult a dentist, as this reflects technique or gum health, not product defect.
