Humble Brush Floss Picks Charcoal 50 Pieces
Lower concern. Bamboo and nylon floss picks unlikely to contain PFAS.
Floss picks are simple plastic and bamboo tools without water-repellent or non-stick coatings that typically trigger PFAS use. Brand provides no PFAS disclosure, but product category carries minimal risk.

What Humble Brush Floss Picks Charcoal 50 is made of, ingredients and materials
This product combines a bamboo handle with nylon floss and a charcoal coating. Bamboo is a natural, rapidly renewable material that does not require the synthetic binders or heavy-metal pigments common in plastic alternatives. The nylon floss itself is a standard food-contact polymer with no known leaching concerns at room temperature and normal use. The charcoal coating is a surface treatment applied for appearance and minor absorbent properties; there is no public record of hazardous additives in this specific application on floss picks.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Microplastics
Nylon floss fibers may shed microscopic fragments during normal use, but ingestion via floss pick is incidental and not a recognized exposure pathway compared to textiles or food-contact packaging.
Source, EPA ↗What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Formaldehyde / VOCs
Bamboo processing may involve formaldehyde-based adhesives, but floss picks are not heat-processed post-manufacture and oral contact is minimal and brief. No formaldehyde off-gassing has been reported for this product category.
Source, ATSDR ↗Heavy metals
Charcoal pigments and coatings are not standardly tested for lead, cadmium, or arsenic in food-contact applications. No public record of contamination exists for floss-pick charcoal coatings specifically.
Source, FDA ↗Bamboo processing contaminants
Bamboo handles may retain pesticide residues from cultivation or processing solvents, but oral-contact risk is negligible and no recalls have been issued for this product type.
Dyes or finishes on handle
The charcoal coating is the only named finish; azo dyes or other colorants are not documented for Humble Brush floss picks and bamboo handles typically use natural finish or minimal treatment.
The full breakdown
The brand's record and disclosure
Humble Brush has no established safety recalls or regulatory warnings on record for this product line. The brand maintains silent positioning on PFAS, which limits independent verification of supply-chain screening. Bamboo toothbrush and floss pick manufacturers rarely undergo third-party material testing for heavy metals or coatings, so formal certifications are uncommon across this market segment. The company's sustainability messaging does not address chemical safety protocols.
How it compares in its category
Floss picks as a category carry minimal chemical exposure risk compared to other oral-care or cosmetic products because contact time is brief and the product does not enter the mouth in bulk. Bamboo variants pose lower concern than plastic-handled alternatives due to absence of synthetic polymers and their associated additives. Charcoal coatings on wood products are not on record as a source of concern, though they remain largely unregulated for food-contact use.
If you buy it
Store picks in a cool, dry location to prevent moisture damage to the bamboo handle. Do not soak or leave wet for extended periods, as this can promote mold on natural material. The nylon floss is single-use and should be replaced when frayed. No special cleaning of the handle is necessary beyond occasional wiping with a dry cloth.
