What TamponTribe Menstrual Cups is made of, ingredients and materials
TamponTribe cups are stated to be medical-grade silicone, a non-porous elastomer with no known plasticizers, BPA, or phthalates added during manufacturing. Medical-grade silicone is chemically inert at body temperature and does not leach endocrine disruptors under normal vaginal use. The concern is not the silicone itself, but whether the brand's supply chain or additives (colorants, vulcanization residues) introduce contaminants, a gap the brand has not publicly addressed.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Bacterial colonization and biofilm formation
Any reusable silicone menstrual cup can harbor bacteria if not boiled or air-dried fully between uses. TamponTribe's product-specific cleaning instructions are not publicly detailed; improper maintenance increases risk of urinary tract infection or bacterial vaginosis, not toxin leaching.
Silicone degradation and surface breakdown
Medical-grade silicone can degrade over 5-10 years with repeated heat exposure, pH changes, and friction. If the TamponTribe cup develops cracks, sticky residue, or discoloration, degradation may release microscopic silicone particles or trapped residues into tissue.
Allergic reaction or sensitivity to silicone
Silicone allergy is rare but documented; some users report irritation or contact dermatitis. This is not a TamponTribe-specific issue but applies to all silicone menstrual cups. Patch test or start with a lower-cost alternative if you have known silicone sensitivity.
PFAS
The brand's PFAS grade is 70/100 (good but not excellent) and the brand provides no public testing data. PFAS may be present in trace amounts from supply-chain inputs or manufacturing; the brand's silence prevents informed choice.

Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Colorant or vulcanization residues
No public record of heavy metals, azo dyes, or toxic residues in TamponTribe cups. Medical-grade silicone typically uses FDA-approved vulcanization systems; however, the brand provides no certificate of analysis or third-party verification to confirm this.
How is this PFAS grade calculated?
The brand's record and disclosure
TamponTribe does not publish PFAS testing, third-party certifications (e.g., FDA 510(k), CE marking), or ingredient transparency statements on available public record. The brand's silence on PFAS and chemical testing is typical of smaller menstrual-product makers, but it creates uncertainty for consumers prioritizing low-PFAS products. No major recalls or contamination incidents are on record for this brand as of available data.
How it compares in its category
Menstrual cups as a category carry lower chemical leaching risk than single-use tampons or pads because silicone does not absorb fluids the way cotton or rayon do, and reusable design eliminates additives like bleach residues or synthetic fragrances. TamponTribe sits in the mid-tier of the menstrual-cup market; established brands like Saalt, Lunette, and DivaCup publish third-party testing; TamponTribe does not, creating a transparency gap rather than a material safety gap.
If you buy it
Boil the cup for 5-10 minutes before first use and monthly thereafter to reduce bacterial biofilm risk. Do not use in an autoclave or dishwasher above 80°C, as high heat can degrade silicone durability over many cycles. Replace the cup every 5 years or if you notice discoloration, odor that does not wash out, or sticky residue, signs of silicone degradation or trapped contaminants. Store dry in a breathable pouch, never in a sealed plastic bag, to prevent mold and odor.
