Intimina Lily Menstrual Cup A
Lower PFAS concern; silicone menstrual cups rarely require PFAS treatments.
Intimina Lily Cup A is primarily medical-grade silicone, a material not typically associated with PFAS use. Menstrual cups do not require water repellency, stain resistance, or nonstick coatings, PFAS-prone treatments common in apparel and cookware.

The full breakdown
What it's made of and why it matters
The Lily Cup A is constructed from medical-grade silicone, a synthetic polymer chosen specifically for menstrual products because it resists degradation, does not leach known endocrine disruptors, and tolerates repeated sterilization. Medical-grade silicone undergoes stricter purity controls than food-grade silicone and is designed to meet biocompatibility standards (ISO 10993 series). Unlike latex or some lower-cost elastomers, silicone does not contain phthalates or BPA by formulation. The material's stability means it maintains integrity through boiling and microwave sterilization without releasing volatile compounds.
The brand's record and disclosure
Intimina is a subsidiary of Lupin Pharma and markets the Lily Cup across multiple regions; the product carries FDA clearance in the US and CE marking in Europe, indicating regulatory review. The brand does not publicly disclose detailed material sourcing, manufacturing origin, or independent third-party testing results for heavy metals or residual monomers. No product recalls or safety complaints have been established in public health databases or consumer safety records. The brand's silence on PFAS and broader chemical transparency is typical of the menstrual cup market but not a documented safety failure.
How it compares in its category
The Lily Cup A sits in the mid-to-premium segment of silicone menstrual cups and is comparable to Diva Cup, Saalt, and Lunette in material and design. All mainstream brands use medical-grade or food-grade silicone, making material composition roughly equivalent; differentiation rests on ergonomics, stem design, and brand transparency rather than hazard profile. Intimina's product does not stand out as notably safer or riskier than established competitors. Lower-cost alternatives sometimes use cheaper elastomers or undisclosed materials, but the Lily Cup A avoids that risk category.
If you buy it
Boil or steam-sterilize between cycles according to package instructions; do not expose to sustained high heat (above 150°C/300°F) outside sterilization cycles, though silicone is extremely heat-stable. Inspect the cup for tears, discoloration, or odor changes yearly; replace if material shows visible degradation or loss of grip texture. Wash with warm water and mild soap between insertions and after sterilization. Store dry in the provided pouch or a breathable cloth bag; avoid prolonged storage in airtight plastic, which can trap moisture.
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.”
Residual silicone monomers and oligomers
Manufacturing of silicone can leave trace cyclic oligomers; medical-grade material reduces but does not guarantee zero residue. No published tests of Lily Cup A for specific monomer levels are available. Initial rinse or boiling before first use may reduce residual content.
Heavy metals in pigments (if colored variants)
The Lily Cup A is available in clear and opaque color options. Medical-grade silicone typically does not use problematic pigments, but published testing of Intimina products for lead or cadmium is not on record. No recalls or alerts have been issued.
Bacterial growth if stored wet or contaminated
This is a use and maintenance hazard, not a material defect. Silicone itself does not promote microbial growth, but improper storage or incomplete drying creates opportunity for biofilm. Follows standard menstrual cup care guidance.
Allergic reaction to silicone (rare)
True silicone allergy is extremely rare but documented in medical literature. Individuals with prior sensitivity to silicone implants or medical devices should consult a provider. Intimina does not publish allergen testing or patient adverse event summaries.
Coating or gloss degradation over time
High-quality medical-grade silicone does not typically develop peeling or discoloration with normal use and care. No published wear-out or coating failure issues specific to the Lily Cup A exist in consumer reports.
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.
