nixit Menstrual Disc and Wash
Lower PFAS concern for the disc; wash formulation opaque, ask the brand.
Nixit's menstrual disc is medical-grade silicone, a material not typically associated with intentional PFAS use. The company does not disclose PFAS avoidance or claim PFAS-free status.

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 Nixit disc is constructed from medical-grade silicone, a material widely used in FDA-cleared menstrual cups and medical devices because it resists degradation, does not leach chemicals under normal body-temperature use, and is hypoallergenic for most users. Medical-grade silicone has no phthalates, BPA, or other endocrine disruptors inherent to its formulation. The wash product's material composition is proprietary and unspecified on the label, which limits independent assessment of its chemical safety.
The brand's record and disclosure
Nixit does not publicly disclose detailed ingredient lists for the wash or provide third-party safety certifications (e.g., dermatology testing, EWG verification). The brand has not published a PFAS policy or testing results, leaving exposure risk from the wash unclear. No major recalls or safety incidents are on record for the disc itself, and the product obtained FDA 510(k) clearance as a Class II medical device, which requires biocompatibility testing but not full chemical transparency.
How it compares in its category
Nixit's disc design and silicone material are comparable to other cleared menstrual cups (Saalt, Lunette, Periods) in safety profile. The distinguishing factor is the bundled wash, which most competitors do not include or promote; rival cup manufacturers typically recommend plain water or mild soap. This means you are evaluating both a low-risk device and an unknown cleanser formulation in one purchase.
If you buy it
Boil or sterilize the disc before first use and between cycles per instructions; do not use bleach or harsh scrubbers that degrade silicone. If using the Nixit wash, patch-test on skin first to rule out sensitivity to undisclosed ingredients. Replace the disc every 2-3 years or if creasing, discoloration, or odor persists after cleaning. Contact the brand directly for a full wash ingredient list and PFAS testing status before committing to the bundle.
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 over time
Medical-grade silicone is durable but can develop microscopic cracks or odor-trapping biofilm if boiled excessively or exposed to high heat repeatedly; this does not constitute immediate toxicity but signals end-of-life.
Wash formulation allergens or irritants (unknown)
The Nixit wash ingredient list is not publicly available; it may contain fragrance, preservatives, or surfactants that trigger vulvovaginal irritation in sensitive users, and the risk cannot be quantified without full disclosure.
Bacterial or mold colonization if improperly dried
Any menstrual cup, regardless of material, can harbor odor-causing or pathogenic bacteria if stored wet or in humid conditions; silicone does not prevent this, though it resists staining.
Talc or heavy metal contamination in pigments
Nixit discs are typically clear or lightly colored; no reports of talc or pigment-based heavy metal exposure exist for this brand, and medical-grade silicone does not inherently contain these contaminants.
Microplastics from wear
Medical-grade silicone does not shed microplastics under normal use; however, if the disc is torn or severely degraded and small pieces are shed, ingestion is theoretically possible but not documented as a real-world risk for this product.
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.
