AllMatters Cup Starter Kit
Lower concern product; silicone cups unlikely PFAS vector, but brand silence on materials limits full assurance.
AllMatters menstrual cup starter kits are made from medical-grade silicone, a material not typically associated with PFAS use. Period-care products don't require water-repellent or nonstick coatings that are common PFAS sources.

The full breakdown
What it's made of and why it matters
The AllMatters Cup is constructed from medical-grade silicone, a high-purity polymer backbone with minimal additives compared to consumer-grade silicone. Medical-grade silicone is specifically formulated and tested to withstand repeated sterilization (boiling, autoclaving) without degrading or leaching problematic compounds into body fluids. No coatings, glazes, or enamels are disclosed, eliminating common hazard vectors like lead in glazes or Teflon-type coating fume risk. Silicone's inert nature means it does not readily leach plasticizers, BPA, or phthalates under normal use conditions.
The brand's record and disclosure
AllMatters provides material specifications identifying medical-grade silicone but does not publicly detail supplier identity, manufacturing standards (ISO 10993 biocompatibility certification status), or independent third-party testing results. The brand's silence on PFAS in supply chain or manufacturing processes is consistent with many small menstrual cup manufacturers but limits independent verification. No recalls or safety controversies for this product appear in public databases. The lack of transparency on these upstream details is a minor concern but not a disqualifying factor given silicone's inherent low-migration profile.
How it compares in its category
Medical-grade silicone cups (AllMatters, DivaCup, Saalt, Lunette) are considered the safest menstrual cup option compared to latex, rubber, or thermoplastic elastomer alternatives, which may contain more additives and allergens. AllMatters sits in the middle price tier and offers no distinctive material advantage over competitors, though all silicone cups share the same low chemical hazard baseline. Silicone cups are superior to disposable tampons and pads in avoiding synthetic fibers, bleach residues, and dioxin concerns, though that comparison crosses product categories.
If you buy it
Boil the cup before first use and after each cycle to sterilize; silicone withstands repeated boiling without degradation. Do not expose to open flame, prolonged sunlight, or harsh solvents, which can degrade the material surface over time (though this affects function, not chemical safety). Replace the cup every 5-10 years or if you notice visible tears, brittleness, or odor that cleaning does not remove. Store in a breathable pouch (typically provided) rather than airtight containers to prevent mold and odor accumulation.
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 leaching (thermal/mechanical stress)
Medical-grade silicone is highly resistant to leaching under normal vaginal conditions, but repeated boiling, autoclaving, or exposure to alcohol-based cleaners can gradually degrade surface properties over years. No specific leachate migration data for AllMatters Cup appears in public literature; degradation is primarily a durability concern rather than acute toxicity risk.
Bacterial and mold contamination (maintenance failure)
Menstrual cups in general carry a documented low but real risk of bacterial overgrowth (including toxic shock syndrome bacteria) if not cleaned, boiled, or stored properly between cycles. AllMatters Cup material itself is not a vector, but user care lapses are common. Manufacturer guidance on sterilization frequency is essential; verify it is present in product documentation.
Allergic reaction to silicone or residual additives
True silicone allergy is extremely rare and would be reported widely across the medical cup category. No published allergic reactions specific to AllMatters Cup are on record. Fragrance, scent, or color additives in some cups can trigger irritation; AllMatters Cup is marketed as scent-free and plain, reducing this risk.
Heavy metals in silicone feedstock or pigments
Medical-grade silicone is subject to USP/EP purity standards that limit heavy metal impurities; AllMatters does not disclose third-party metal testing, but silicone cups as a class do not appear in heavy metal contamination alerts. No recalled batches of medical-grade silicone cups for metal content have been documented.
Oxidation and hardening over time
Silicone can harden and lose elasticity after 5-10 years of use, especially if stored in warm or UV-exposed conditions. This is a functional degradation (cup becomes less flexible, less effective) rather than a chemical safety hazard, but worn cups may harbor bacteria more easily if cracks form. Regular replacement prevents both issues.
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.
