OrganiCup size B in silicone | AllMatters
Lower-concern menstrual cup; silicone itself poses minimal PFAS risk, but brand makes no public PFAS statement.
OrganiCup's Size B is made from medical-grade silicone, a material not typically treated with PFAS coatings or finishes. Silicone menstrual cups carry lower inherent PFAS risk than products requiring water-repellency or non-stick properties.

The full breakdown
What it's made of and why it matters
OrganiCup Size B is constructed from medical-grade silicone, a synthetic polymer designed for biocompatibility and repeated internal contact. Medical-grade silicone does not contain BPA, phthalates, or plasticizers that migrate into body fluids under normal use conditions. The material is non-porous, chemically stable at body temperature, and resistant to degradation from menstrual fluid or common cleaners, making it fundamentally different from lower-cost silicone alternatives.
The brand's record and disclosure
AllMatters (OrganiCup's parent company) has not published a formal PFAS statement, which is noteworthy given industry movement toward transparency on fluorinated compounds in menstrual products. The product itself carries no documented safety recalls or complaints in major safety databases. The brand emphasizes sustainability and materials transparency in marketing but has not independently verified medical-grade claims through third-party certification bodies like FDA or ISO 10993 biocompatibility testing on the public record.
How it compares in its category
Menstrual cups as a category pose lower chemical risks than disposable pads or tampons because they avoid absorbent materials, adhesives, and bleaching agents. OrganiCup competes directly with Saalt, Luna, and Flex, all silicone-based with similar inert material profiles. Unlike some budget silicone cups, OrganiCup does not report talc contamination or use recycled silicone of uncertain provenance, placing it in the safer segment of the category.
If you buy it
Boil the cup before first use and after each cycle to eliminate bacteria and reduce contamination risk. Rinse with unscented, non-antibacterial soap between insertions; avoid fragrant douches and harsh chemicals that do not improve safety but may cause irritation. Replace the cup every 5 years or sooner if the silicone shows visible cracking, pitting, or discoloration. Store in a breathable pouch, not sealed plastic, to prevent mold growth during storage.
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.”
Bacterial growth and contamination
Silicone cups are nonporous but can harbor bacteria if not thoroughly cleaned or dried between cycles. Improper storage in sealed containers or infrequent boiling increases infection risk, though OrganiCup's marketing materials include cleaning guidance that mitigates this.
Silicone degradation and particle shedding
Medical-grade silicone is chemically stable and does not degrade under normal menstrual-cup use or body-temperature storage. No documented cases of particulate shedding or breakdown specific to OrganiCup exist in public records.
Allergen/irritation from additives or residual monomers
Medical-grade silicone used in OrganiCup is post-cured and finished to remove free oligomers and uncrosslinked chains that can cause irritation. The brand does not disclose independent biocompatibility test results, but no complaints of sensitization have been widely reported.
Leaching of colorants or dyes
OrganiCup is available in natural (translucent) or lightly pigmented silicone; silicone pigments used in medical devices are typically iron oxides or synthetic inorganic compounds that do not leach into aqueous fluids at body temperature.
Thermal degradation from boiling
Medical-grade silicone has a thermal stability threshold well above boiling water (212°F / 100°C) and does not degrade or release volatile compounds at these temperatures. Boiling is the recommended sterilization method and poses no documented risk to this material.
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.
