nixit Menstrual Disc, Wash, Wipes, Lube, Tote
Lower PFAS concern, core materials are silicone and cotton, but no public PFAS disclosure from brand.
Nixit's menstrual disc is primarily medical-grade silicone, a non-fluorinated elastomer not typically associated with intentional PFAS. Wipes and wash appear to use conventional cotton/cellulose and water-based formulations.

Safe base material
Made from a material with no inherent PFAS use (ceramic, mineral, or natural fiber).
The full breakdown
What it's made of and why it matters
The menstrual disc is medical-grade silicone, a non-porous elastomer that does not leach estrogenic compounds like BPA and resists degradation during normal use and cleaning. The wipes are a cotton/polyester blend, and the wash and lubricant are water-based formulations, all materials with established safety records in intimate-contact applications. Silicone does not off-gas volatile organic compounds (VOCs) at body temperature, and cotton/water systems carry negligible risk of chemical migration into sensitive tissue.
The brand's record and disclosure
Nixit does not publicly disclose material test reports, safety certifications, or third-party audit results on their website or marketing materials. The brand has not issued statements addressing PFAS, phthalates, or heavy metal contamination, which is typical for smaller menstrual-product manufacturers but limits independent verification. No recalls or safety complaints have been documented in FDA or consumer databases for this product line. The brand's silence on chemical testing is not unusual in this category but represents a missed opportunity for transparency.
How it compares in its category
Medical-grade silicone menstrual discs are generally considered lower-risk than latex or rubber alternatives, which can contain residual proteins and allergens. Compared to traditional menstrual cups (also silicone), discs have a larger surface area and different insertion mechanics, but identical material safety profiles. Wipes and lubricants bundled with premium menstrual products often lack third-party certification (fragrance-free, hypoallergenic labeling); Nixit's water-based formulations align with industry practice rather than exceeding it.
If you buy it
Wash the disc and reusable components with mild soap and water before first use and after each cycle; avoid bleach or boiling, which can degrade silicone over time. Store in a breathable bag (included tote) to prevent moisture accumulation and mold; inspect the disc quarterly for tears, permanent discoloration, or brittleness as signs of material breakdown. If irritation develops, discontinue use and patch-test the wash and lube on non-sensitive skin to isolate the cause. Replace the disc every 2-3 years or if structural integrity is compromised.
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.”
Silicone degradation and leachables
Medical-grade silicone is chemically stable, but prolonged exposure to heat (boiling, dishwasher), UV light, or aggressive solvents can cause surface cracking and microparticle shedding. No specific leachate toxicology studies for Nixit disc are publicly available; risk is low under normal use but increases with improper care.
Fragrance allergens (wipes, wash, lube)
Product labeling does not confirm fragrance-free formulation for wash or lube; undisclosed fragrance components (natural or synthetic) can trigger contact dermatitis or vulvovaginal irritation in sensitive users. Nixit provides no ingredient list for these accessory products on their public-facing materials.
Microplastics from polyester wipes
The cotton/polyester blend wipes may shed microfibers during use and washing; while ingestion risk is low in this application, microfiber shedding into aquatic systems is a documented concern for all synthetic textiles. Long-term dermal accumulation from repeated wipe use is not quantified.
Bacterial or mold colonization
Silicone is non-porous but can harbor biofilm in folds or seams if not dried thoroughly between uses; the included tote, if used damp, may promote mold growth on the disc or wipes. Nixit provides no specific guidance on antimicrobial maintenance or replacement intervals for the tote.
Heavy metals or dyes in cotton wipes
No recalls or test data documenting lead, cadmium, or azo dye contamination in Nixit wipes have been reported. Cotton textile safety is regulated under OEKO-TEX and Bluesign standards in many manufacturers, but Nixit does not advertise compliance with either certification.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% 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.
