What Delicious Mint Woven Dental Floss is made of, ingredients and materials
Cocofloss Mint uses plant-based fibers (typically derived from sustainable sources) coated with wax, rather than the nylon or polyester found in conventional dental floss. The wax coating provides glide and structural integrity without relying on synthetic polymer bases. Plant-based fiber floss avoids concerns tied to microplastic shedding from synthetic alternatives and reduces reliance on petroleum-derived materials. The mint flavoring is applied to the wax; the actual hazard profile depends on whether synthetic fragrance compounds or natural mint extract are used, which is not disclosed in available product information.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
Fragrance allergens and sensitizers
The mint flavoring formulation is not specified; if synthetic fragrance compounds are used, potential for contact sensitization exists in susceptible individuals, though no adverse events are on record for this product.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Third-party PFAS-free verification
A third party reports verifying this product as PFAS-free.
Formaldehyde / VOCs
Plant-based waxed fibers do not typically require formaldehyde-releasing resin treatments; MADE SAFE certification would flag such use if present. No evidence of formaldehyde exposure risk in this product.
Source, ATSDR ↗Heavy metals
Mint coloring and wax coating are minimal in mass; MADE SAFE certification includes heavy metal testing. No contamination reported or flagged for this product line.
Source, FDA ↗1,4-dioxane as manufacturing byproduct or contaminant
MADE SAFE certification explicitly tests for 1,4-dioxane residues. No evidence of this concern in Cocofloss products.
How is this PFAS grade calculated?
The brand's record and disclosure
Cocofloss has obtained MADE SAFE certification, a third-party program that tests for harmful chemicals including heavy metals, phthalates, and volatile organic compounds. The brand explicitly markets PFAS-free status and has been transparent about material sourcing as plant-based and sustainably harvested. No product recalls, safety complaints, or regulatory actions are on record for this floss line. The brand does not disclose the complete ingredient list (specific wax type, fragrance source) on packaging or their website, limiting independent verification of all components.
How it compares in its category
Typical dental floss falls into nylon monofilament (conventional), polyester tape, or plant-based waxed fiber categories. Nylon and polyester flosses carry no significant chemical hazard on record but may shed microplastics with repeated use. Plant-based waxed floss, including Cocofloss, eliminates microplastic risk and aligns with consumers prioritizing natural materials, though efficacy and durability are individual factors. MADE SAFE certification is less common in the floss category, making this product a higher-transparency choice than most mass-market alternatives.
If you buy it
Store floss in a cool, dry location away from direct heat or humidity to preserve the wax coating and prevent degradation. Replace the spool when fibers begin to fray or lose wax coating, typically every 2-4 weeks depending on use. If you have sensitive gums or are prone to gum bleeding, introduce any new floss gradually and discontinue if irritation develops. As with all dental floss, do not swallow; discard used lengths in the trash, not down the drain.
