OrganiCup size B in silicone | AllMatters
Lower-concern choice; silicone menstrual cups have no established PFAS risk pathway, but brand offers no transparency.
OrganiCup is manufactured from medical-grade silicone, a non-Teflon-family coating material with no typical PFAS application in period-care products. AllMatters provides no public PFAS disclosures or claims, which is typical for the category.

No PFAS disclosure
No public statement about PFAS in this product.
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
OrganiCup Size B is constructed from medical-grade silicone, a synthetic polymer widely used in internal medical devices because it resists degradation from body fluids and does not leach plasticizers or BPA. Silicone's cross-linked structure differs fundamentally from flexible PVC or polycarbonate, making it chemically inert during typical use (37°C internal body temperature, acidic/aqueous vaginal environment). The material has a documented 10-year shelf life and can withstand repeated sterilization without structural breakdown.
The brand's record and disclosure
AllMatters (the manufacturer/distributor) provides no independent material certifications or published testing data for PFAS, heavy metals, or volatile organic compounds. The company markets the product as organic-aligned but does not publish manufacturing standards, third-party lab reports, or supply-chain transparency beyond the medical-grade claim. No product recalls, contamination incidents, or complaints of chemical exposure have been established in published sources.
How it compares in its category
Medical-grade silicone menstrual cups (OrganiCup, Lunette, Saalt, DivaCup) occupy the lower-hazard end of period products because they avoid paper bleach (dioxins), synthetic fragrance, and absorbent polymer additives found in tampons and pads. Silicone cups eliminate single-use waste and repeated chemical exposure but require proper cleaning; comparable silicone brands rarely differ in material composition, though transparency varies. AllMatters' product is chemically equivalent to mainstream competitors; brand selection hinges more on fit, stem design, and user preference than safety differentiation.
If you buy it
Rinse the cup thoroughly before first use and after each emptying with lukewarm water or a fragrance-free wash; avoid petroleum jelly lubricants (use water or silicone-based lube). Sterilize monthly by boiling in water for 5-10 minutes or using a dedicated cup sterilizer; do not use bleach or harsh chemicals. Replace the cup if you notice discoloration, odor that persists after cleaning, or visible wear; most users report 5-10 years of reliable use before degradation. Store in the provided pouch in a cool, dry place between periods.
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 or leaching under extreme conditions
No evidence of silicone monomer or oligomer leaching during vaginal use at body temperature. Degradation risk is only documented under prolonged exposure to harsh solvents or high heat (>200°C), which do not occur in normal use.
Bacterial growth and biofilm formation if improperly cleaned
Silicone's surface texture can harbor bacteria if the cup is not rinsed immediately after removal or stored while damp. This is a maintenance issue, not a material hazard, but hygiene failure increases TSS (toxic shock syndrome) risk, a concern for all internal menstrual products, not specific to this brand.
Contact dermatitis or allergic sensitization to silicone
Documented allergic reactions to medical-grade silicone are extremely rare (<<1% of users). No case reports of silicone-specific dermatitis linked to OrganiCup or AllMatters in available literature.
Residual manufacturing impurities or additives
AllMatters provides no published analysis of colorants, curing catalysts, or trace metals in the finished silicone. Medical-grade silicone should undergo biocompatibility testing per ISO 10993, but the company does not disclose test results publicly.
Fragrance or antimicrobial coating additives
OrganiCup Size B is unfragranced and free from advertised antimicrobial treatments. No added irritant compounds are evident from product description, though independent analysis would confirm absence of synthetic fragrance compounds or zinc pyrithione.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 78% 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.
