INTIMINA Lily Cup, Menstrual Cup, Period Cup, Size B, medical-grade silicone
Lower concern; silicone menstrual cups are not typical PFAS application products, though direct brand testing would strengthen confidence.
The Intimina Lily Cup is made from medical-grade silicone, a material class not typically formulated with PFAS. Menstrual cups do not require water-repellent, grease-resistant, or non-stick coatings, the main drivers of PFAS use in consumer products.

The full breakdown
What it's made of and why it matters
The Lily Cup is manufactured from medical-grade silicone, a synthetic rubber polymer that is chemically inert and does not leach estrogens, plasticizers, or other endocrine disruptors under normal body-temperature use. Medical-grade silicone is specifically formulated for biocompatibility and is not cross-linked with BPA, phthalates, or other common plastic additives. The material does not degrade into microplastics during the typical 5-10 year lifespan of a menstrual cup.
The brand's record and disclosure
Intimina is a woman-focused sexual and menstrual health brand owned by Pjur Group, a European manufacturer with a documented quality-control history but limited public third-party safety testing disclosures for this specific product. The company claims medical-grade silicone compliance but does not publish formal FDA approval documentation or independent testing reports. No major product recalls or safety complaints about the Lily Cup have been reported in major consumer safety databases or regulatory filings.
How it compares in its category
Medical-grade silicone menstrual cups are considered one of the lowest-risk period product categories because the material is chemically stable, non-porous, and does not interact with vaginal fluids or bacteria at body temperature. The Lily Cup is comparable in material safety to other leading silicone cup brands such as DivaCup or Saalt, all of which rely on the same base material chemistry. Unlike disposable pads and tampons (which may contain rayon, plastics, and adhesives), reusable silicone cups eliminate repeated exposure to manufacturing residues.
If you buy it
Wash the cup thoroughly with mild soap and warm water after each use and before reinsertion; do not use oil-based soaps or harsh scrubbers that could microscopically degrade the surface. Store in the provided breathable pouch in a dry location; do not seal in airtight plastic bags or expose to direct sunlight for extended periods, as silicone can absorb odors and discolor over time. Replace the cup every 5-10 years or if you notice visible cracks, sticky residue, or persistent odor that does not wash away, as these signal material breakdown. Do not boil aggressively or use bleach; gentle steam or water-based sterilization methods are sufficient and safer for long-term material integrity.
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 odor absorption
Medical-grade silicone can absorb vaginal odors and discolor slightly over prolonged use, though this is a cosmetic and hygiene concern rather than a chemical safety hazard. Microscopic surface breakdown from harsh cleaning or storage in airtight conditions is not documented for this product but is a general silicone aging risk.
Vaginal irritation or allergic reaction to silicone
True silicone allergies are extremely rare in medical settings; no case reports of allergic reaction to Intimina Lily Cup silicone have been published. However, pre-existing sensitivities to silicone in medical implants or tubing are the only documented contraindication.
Bacterial colonization if improperly cleaned
Silicone is non-porous and resistant to bacterial biofilm formation, but poor rinsing or storage in damp conditions can allow bacterial overgrowth in residual fluid; this is a hygiene issue, not a material toxicity issue. Proper drying and occasional sterilization eliminate this risk.
Heavy metals or contaminants in silicone formulation
Medical-grade silicone manufacturing standards (such as USP Class VI or ISO 10993) require testing for heavy metals and residual monomers, but Intimina does not publicly disclose independent verification of these tests for the Lily Cup. No regulatory agency has identified contamination in this product.
Leachates from silicone or printing inks during use
The cup itself does not leach chemicals; however, printed logos or labels on the exterior are not always tested for migration under body temperature and moisture. Avoid inserting the cup upside-down or in contact with interior vaginal tissue via the printed side.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 82% 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.
