What DivaCup Model 0 is made of, ingredients and materials
The DivaCup Model 0 is constructed from medical-grade silicone, a synthetic polymer that does not contain BPA, BPS, phthalates, or latex. Medical-grade silicone is specifically formulated and tested for prolonged contact with mucous membranes and has inherent resistance to microbial growth and degradation. Unlike lower-grade silicone or elastomers, medical-grade material undergoes rigorous biocompatibility testing per ISO 10993 standards. The material's inert chemistry means it does not leach endocrine disruptors or other synthetic additives during normal use or cleaning.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
Silicone degradation or leaching from improper cleaning agents
Bleach, hydrogen peroxide, and certain oils can degrade medical-grade silicone over extended exposure. Risk is low with water or approved cleansers but increases if users substitute harsh chemicals. No reported incidents specific to DivaCup Model 0 are on record.
Bacterial or fungal colonization from inadequate cleaning or storage
Any reusable internal device carries intrinsic risk if not cleaned or dried properly between cycles. This is a user-practice hazard, not a material defect. Boiling and air-drying as directed mitigates this risk substantially.
Vaginal irritation or allergic response to silicone
Medical-grade silicone is hypoallergenic by design, but rare individual sensitivities to silicone have been documented in clinical literature. The DivaCup Model 0 has no pattern of adverse event reports in regulatory databases, but pre-existing silicone sensitivity warrants patch testing or consultation with a healthcare provider.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Third-party PFAS-free verification
A third party reports verifying this product as PFAS-free.
No PFAS found in lab test
No PFAS detected in independent testing.
Microplastics
Medical-grade silicone used in approved menstrual cups and medical implants does not break down into microplastics under normal use. No testing data or field reports indicate shedding from the DivaCup Model 0 with proper care.
Source, EPA ↗Heavy metals
Medical-grade silicone formulations do not rely on heavy metal catalysts or azo dyes typical of textiles or lower-grade plastics. Third-party PFAS verification testing by the brand provides confidence in raw material purity, though comprehensive heavy metal profiling is not publicly disclosed for this specific product.

The brand's record and disclosure
Diva International has published material safety data and third-party PFAS test results confirming the absence of detectable PFOA/PFOS and related PFAS "forever chemicals" in the DivaCup. The company provides clear product documentation and has engaged independent laboratories for materials verification. No recalls or reported contamination incidents related to the DivaCup have been established in public health records or regulatory databases. The brand's transparency on silicone sourcing and manufacturing is consistent with medical device category norms.
How it compares in its category
Menstrual cups made from medical-grade silicone represent a lower-leaching alternative to single-use absorbent products and some competing cups made from elastomer blends or lower-grade silicone formulations. The DivaCup's material standard is typical among leading menstrual cup brands certified for vaginal use. Unlike some reusable fabric or bamboo alternatives, silicone cups do not shed microfibers and eliminate concerns about pesticide residues from textile production. The Model 0 (smaller size) is designed for lower-flow days or lighter-flow bodies, making it a targeted choice rather than a universal product.
If you buy it
Rinse thoroughly with water or use the brand-supplied cleansing wipes before insertion and after removal. Clean the cup at the end of each cycle by boiling in water for 5-10 minutes or using the provided DivaCup cleanser to prevent bacterial biofilm accumulation. The product is reusable for 10+ years with proper care; replace if the silicone becomes visibly degraded, sticky, or develops persistent odor. Do not expose to bleach, hydrogen peroxide, or oil-based lubricants, which can compromise silicone integrity over time.
