What Love of Earth Co. Floss + Glass Case is made of, ingredients and materials
Dental floss marketed as plant-based (typically cellulose or silk) avoids synthetic polymer matrices that can leach plasticizers or degradation byproducts into the oral cavity. Glass cases are chemically inert and do not leach contaminants into the floss or environment over time. The simplicity of these materials means few synthetic additives or stabilizers are needed, reducing the overall chemical exposure profile compared to nylon or polytetrafluoroethylene (Teflon-type coating) floss variants.
What’s concerning
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
Fragrance allergens or undisclosed additives
Marketing implies plant-based composition, but full ingredient lists and fragrance/flavoring disclosures are not publicly available. Some eco-brands add essential oils or flavor agents without detailed allergy labeling.
Microbial growth if floss is stored damp
Organic plant-based fibers in a moist environment may support bacterial or fungal colonization more readily than synthetic alternatives. Proper drying and storage in the glass case are essential for long-term safety.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Dyes or colorants in floss
No public reports of azo dyes, heavy metal pigments, or synthetic colorants in this product. If the floss is dyed, composition and safety testing are not documented in available sources.
Formaldehyde / VOCs
Plant-based and silk fibers do not inherently require formaldehyde for preservation or cross-linking; no known preservation additives are listed or reported for this product.
Source, ATSDR ↗Glass case integrity and microplastic shedding
Glass is chemically stable and does not shed microplastics. However, if the case chips or cracks during use or transport, sharp edges pose a minor physical injury risk but not a chemical hazard.
How is this PFAS grade calculated?
The brand's record and disclosure
Floss & Ploss (trading as Love of Earth Co.) does not appear in public safety databases or recall registries for this product. The brand maintains a silent stance on PFAS, which is not uncommon for smaller eco-focused manufacturers. No third-party certifications (such as EWG verification or NSF listings) are documented for this specific product, and marketing claims about plant-based composition have not been independently verified in available public records.
How it compares in its category
Plant-based or silk floss represents a lower-risk alternative to conventional nylon floss, which may contain dyes, additives, or residual monomers. Glass packaging is superior to plastic cases, which can off-gas volatile organic compounds (VOCs) or leach BPA/BPS over years of storage. However, without third-party testing or certification, claims about plant-based purity cannot be independently confirmed; consumers rely on brand transparency.
If you buy it
Store the floss in the glass case away from direct sunlight and heat to preserve plant fibers and prevent degradation. Replace floss when it becomes frayed, discolored, or develops odor, as these signs indicate microbial growth or fiber breakdown. Clean the glass case occasionally with mild soap and water; allow it to air dry fully before refilling. Discontinue use immediately if gum irritation, bleeding, or allergic reactions occur, as individual sensitivities to plant materials vary.
