OrganiCup Menstrual Cup
Lower concern, silicone menstrual cups are not a known PFAS vector, but AllMatters does not publicly disclose PFAS absence.
OrganiCup is made from medical-grade silicone, a polymer not typically used for PFAS coatings. Menstrual cups do not require water-repellency, stain resistance, or non-stick treatments that drive PFAS use in other categories.

Why this grade
Category baseline
period care is a category where PFAS exposure is more common.
No PFAS disclosure
No public statement about PFAS in this product.
Uncoated safe material
Bare, uncoated material (cast iron, stainless, carbon steel, or glass) with no surface treatment to contain PFAS.
The full breakdown
What it's made of and why it matters
OrganiCup is manufactured from medical-grade silicone (USP Class VI certified), which is chemically inert and does not leach plasticizers, BPA, or phthalates during normal use or when heated. The stainless steel rim is non-reactive and does not corrode or shed metals into menstrual fluid. Medical-grade silicone is the same material used in clinical implants and surgical devices, designed to withstand repeated sterilization and extended body contact without degradation.
The brand's record and disclosure
AllMatters (the company behind OrganiCup) does not publicly disclose detailed PFAS testing or absence statements on their website or product materials, which is a transparency gap for a health-focused brand. The company holds CE marking and has published safety data sheets indicating USP Class VI silicone compliance, but does not voluntarily communicate beyond regulatory minimums. No recalls, contamination incidents, or safety controversies are on record for this product line.
How it compares in its category
Medical-grade silicone menstrual cups (OrganiCup, Diva Cup, Saalt, Cora, etc.) are chemically safer than disposable pads or tampons, which may contain chlorine residues, rayon microfibers, and fragrance additives. Unlike some cheaper silicone competitors lacking USP certification, OrganiCup's medical-grade material reduces risk of degradation or leaching over repeated use cycles. The stainless steel rim is standard across premium brands and presents no toxicity concern relative to silicone-only designs.
If you buy it
Boil or steam-sterilize before first use and after each cycle (silicone withstands high heat without breakdown). Wash daily with water or mild soap; avoid bleach or peroxide-based cleaners, which degrade the material faster. Replace every 3-5 years or if you notice visible cracks, loss of flexibility, or discoloration; degraded silicone may shed particles. Store in a breathable pouch (not sealed plastic) to prevent mold growth in the cup itself.
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 lose elasticity or develop small tears after repeated boiling or aggressive scrubbing over 3-5 years; no established health risk from degraded particles at typical cup volumes, but replacement is prudent.
Bacterial or fungal colonization if not maintained
Improper cleaning or storage in sealed containers can allow mold or bacterial biofilm growth on the cup surface; this is a hygiene issue, not a chemical hazard, but relevant to safe menstrual cup use.
Allergic sensitization to silicone (rare)
A small population reports local irritation or allergic reaction to silicone; this is not a material contamination issue but individual susceptibility, more common in people with known silicone sensitivities.
Stainless steel rim corrosion
Grade 316L or 304 stainless steel used in menstrual cups is highly corrosion-resistant in acidic menstrual fluid; no leaching of nickel or chromium is established in published literature or recalls.
Formaldehyde or volatile off-gassing
Medical-grade silicone does not contain formaldehyde resins or release VOCs; silicone cups have minimal odor compared to latex or PVC alternatives.
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.
