What Listerine Reach Ultraclean Access Flosser is made of, ingredients and materials

This product combines a plastic handle (likely polystyrene or polypropylene), nylon monofilament floss, and a metal pick. Nylon floss is inert in the mouth and does not leach under normal use conditions. The plastic handle has minimal oral contact and poses no leaching risk during the brief 1-2 minute use cycle. Metal picks are typically stainless steel and chemically stable.

🫧

Microplastic shedding

Repeated bending or damage to the plastic handle during use could theoretically generate microplastic fragments, though the risk is low for a single-use disposable. Proper disposal in trash rather than drains mitigates environmental concern.

70/ 100

What’s reassuring

✅

Base material not linked to PFAS

The main material recorded for this product is not one associated with PFAS.

100/ 100
✅

Nylon floss structural integrity

Nylon monofilament is chemically stable and does not hydrolyze or leach monomers under normal oral use. No reported incidents of nylon floss causing oral irritation or chemical exposure.

95/ 100
✅

Plastic handle leaching (low-temp contact)

Polystyrene or polypropylene handles have minimal contact with saliva and are used for under 2 minutes per application. At mouth temperature (37C), leaching of unreacted monomers or additives is negligible in this brief-contact scenario.

95/ 100
✅

Metal pick corrosion or nickel release

Stainless steel picks do not corrode in the oral environment and do not release nickel under normal use. No reported cases of flosser pick corrosion or metal sensitivity linked to this product type.

95/ 100
💨

Formaldehyde / VOCs

Consumer flossers are not typically treated with formaldehyde-releasing resins or industrial azo dyes. The plastic is a commodity polymer without known antimicrobial or colorfast coatings that would require these chemicals.

How is this PFAS grade calculated?

The brand's record and disclosure

Listerine (owned by Johnson & Johnson) has not published detailed material disclosures or safety certifications specific to this flosser variant. The parent company has faced legacy litigation on talc contamination in personal care products, but that does not apply to oral floss. No recalls of this specific product are on record. Brand transparency on plastics and manufacturing chemistry remains limited.

How it compares in its category

Disposable plastic flossers occupy a middle ground in floss safety. They avoid concerns tied to wooden picks or charcoal-coated variants but generate more plastic waste than string floss alone. Compared to water flossers (which have reservoir concerns and electronic components), this product is simpler and carries lower contamination risk. Most dentists consider nylon floss to have lower concern for PFAS hazards regardless of brand.

If you buy it

Replace the flosser after each use as intended; do not reuse or soak in hot water or mouthwash for extended periods, as this can slightly stress the plastic and theoretically increase minor leaching. Store in a cool, dry place away from direct heat or UV light to prevent polymer degradation. The product requires no cleaning or maintenance beyond disposal. No special precautions are needed for routine daily use.
