Cocolab Cocofloss Dental Floss Refill Duo Young Coconut
Lower-concern choice; coconut floss material itself doesn't typically require PFAS coatings.
Cocofloss uses natural coconut fiber as its primary material, which inherently does not require Teflon-type coating or Teflon-family coating coatings for function. The brand makes no PFAS claims and no public disclosure of PFAS testing. No third-party certifications addressing PFAS were found.

The full breakdown
What it's made of and why it matters
Cocolab Cocofloss is manufactured from coconut-derived fiber, a plant-based alternative to nylon or polyester dental floss. Coconut fiber does not require Teflon-type coating (Teflon) or wax coatings that typically contain PFAS in conventional floss products. The material is biodegradable and poses no risk of microplastic shedding into the mouth or waterways, distinguishing it from synthetic polymer-based floss.
The brand's record and disclosure
Cocofloss maintains no publicly available third-party certifications (e.g., NSF, EWG verification) and does not voluntarily disclose detailed ingredient sourcing or manufacturing testing results on their website or product labeling. The brand has not issued statements addressing PFAS or other chemical safety concerns, which is typical silence rather than a red flag for a small oral-care producer. No recalls or safety complaints have been documented for this product line in publicly available databases.
How it compares in its category
Most conventional floss (Oral-B, Crest, Colgate) uses nylon or Teflon-type coating-coated polyester and typically contains PFAS compounds in the wax or coating. Cocofloss ranks among the safer plant-fiber alternatives (alongside silk or bamboo floss) because coconut fiber inherently resists fraying without chemical additives. However, unlike some competitors, Cocofloss does not advertise organic certification or third-party testing, leaving sourcing transparency lower than premium eco-brands.
If you buy it
Store the refill duo in a cool, dry place away from direct sunlight to preserve the coconut fiber's integrity. Use standard flossing technique; coconut fiber is slightly coarser than nylon and may feel different initially but is equally effective at plaque removal. Replace the spool when strands begin to fray visibly or lose tension. No special care is required; dispose of used floss in regular waste (it will biodegrade within months).
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.”
Fragrance allergens (Young Coconut scent)
The 'Young Coconut' scent variant may contain fragrance compounds not itemized on packaging. While coconut fragrance is generally low-risk, undisclosed essential oils or synthetic odorants could trigger contact dermatitis in individuals with fragrance sensitivity. Cocofloss provides no ingredient list for the flavoring agent.
Fiber degradation and splinter risk
Natural coconut fiber can splinter or shed shorter segments if overused or stored in humid conditions. While floss fragments pose minimal oral injury risk, individuals with gum disease or tissue sensitivity should monitor for any irritation from rough fiber ends.
Microbial growth if refill container is unsealed
The product comes in refill form with a spool that must be stored in a clean container. If the container is not washed between refills or stored in humid environments, bacterial or fungal growth could colonize the fiber before use.
Pesticide residues in coconut source material
No testing data is publicly available for pesticide or fungicide residues in Cocolab's coconut fibers. The brand does not claim organic certification, so conventional coconut farming practices (which may include synthetic inputs) cannot be ruled out, though oral exposure via floss contact is minimal.
Heavy metals in dye or finish (if any)
Coconut fiber floss typically requires no dyes or finishes for color or texture. No reports of lead, cadmium, or other heavy metals in Cocolab Cocofloss exist in available literature; the material's natural color is sufficient.
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.
