Intimina Lily Menstrual Cup B
Lower-concern product; silicone cups rarely require PFAS treatments, but brand transparency is absent.
The Intimina Lily Cup is made from medical-grade silicone, a material not typically treated with PFAS for functional performance. Menstrual cups, unlike nonstick cookware or water-repellent textiles, have no inherent need for fluorochemical coatings.

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 Lily Cup B is manufactured from medical-grade silicone, a synthetic polymer that does not contain plasticizers like phthalates or BPA by design. Medical-grade silicone is formulated to resist degradation in body-temperature and mildly acidic environments and does not leach estrogen-mimicking compounds the way polycarbonate or lower-grade plastics can. The material itself is non-porous and chemically stable when maintained properly, making it suitable for prolonged internal contact.
The brand's record and disclosure
Intimina (owned by Maude/Maude Inc.) has not published detailed ingredient sourcing, manufacturing certifications (e.g., ISO 10993 biocompatibility), or PFAS statements for the Lily Cup B. The product carries no third-party safety certifications visible in public documentation. The brand's silence on chemical transparency is typical for the menstrual-cup sector but limits independent verification of supply-chain controls.
How it compares in its category
Medical-grade silicone cups (Lily, DivaCup, Saalt, Flex) are chemically comparable and generally pose lower toxicant risk than non-medical plastics or latex alternatives. The Lily Cup B is pitched as a budget or travel-friendly option versus the flagship DivaCup, but uses the same base material class. No published safety testing distinguishes it from competitors in this segment.
If you buy it
Wash with fragrance-free soap and water after each use and inspect for visible tears or cloudiness before insertion, which may indicate silicone breakdown. Boil once monthly in plain water for 5-10 minutes to maintain sterility; avoid prolonged exposure to direct heat or UV light, which can degrade silicone over years. Replace every 3-5 years or sooner if you notice loss of flexibility, odor, or discoloration. Store in a breathable pouch, not a sealed plastic bag, to avoid moisture trapping.
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 microparticle shedding
Over extended use or improper storage (heat, UV, harsh chemicals), medical-grade silicone can lose tensile strength and potentially shed microscopic particles. No recalls or adverse-event reports specific to Lily Cup B are on record, but general menstrual-cup silicone durability depends on user maintenance.
Bacterial or mold contamination from improper cleaning
If the cup is not rinsed thoroughly or dried completely before storage, bacteria or mold can colonize the silicone surface, especially in the folds near the rim. This is a user-maintenance issue, not a product defect, but critical for vaginal health.
Allergic reaction or sensitization to silicone or residual manufacturing chemicals
True IgE-mediated silicone allergy is extremely rare; however, residual catalysts or release agents from silicone manufacturing could theoretically trigger contact dermatitis in sensitive individuals. No complaints or recalls for the Lily Cup B have been documented.
Leachables from cup or applicator packaging
The cup itself is silicone, but the storage pouch and any included applicators may contain plastics with unknown composition. Intimina does not disclose packaging material specifications publicly.
Lack of biocompatibility certification transparency
The Lily Cup B is marketed as medical-grade silicone but Intimina has not publicly shared ISO 10993 biocompatibility test reports or FDA clearance details. Competitors (e.g., DivaCup) similarly lack full transparency, making direct safety comparison difficult.
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.
