The Short Answer
Yes, most menstrual pads contain undisclosed chemicals. Because the FDA classifies pads as medical devices, manufacturers aren't required to list their ingredients on the label.
Recent lab testing found that 48% of sanitary pads contain PFAS "forever chemicals." Furthermore, conventional plastic pads emit volatile organic compounds (VOCs) and rely on synthetic fragrances that can severely disrupt vaginal health.
Why This Matters
Vaginal tissue is highly permeable. Chemicals that come into contact with the vulva are rapidly absorbed directly into the bloodstream. This makes chemical exposure from menstrual products uniquely concerning compared to skin contact elsewhere on the body. Are Pads Safe
The average menstruating person uses over 10,000 period products in their lifetime. Chronic, low-dose exposure to endocrine disruptors adds up over time. These chemicals have been linked to hormonal imbalances, fertility issues, and increased risks of reproductive diseases like endometriosis. Tampons Vs Pads Safety
Greenwashing is rampant in the feminine care aisle. In a massive consumer study, 13 of the pads that tested positive for PFAS were marketed as "natural" or "organic." You can't just trust a green box; you have to know what materials are actually being used. Are Organic Pads Worth It
What's Actually In Menstrual Pads
- PFAS ā Polyfluoroalkyl substances are added to make pads leak-proof. Lab tests found PFAS in 48% of pads, with levels ranging from 11 to 154 parts per million (ppm). These "forever chemicals" are linked to reproductive harm and reduced immune function.
- Volatile Organic Compounds (VOCs) ā Testing of Always pads found emissions of styrene (a carcinogen), chloromethane (a reproductive toxicant), and chloroform. These VOCs largely off-gas from the chemical adhesives used to stick the pad to your underwear. Is Always Pads Safe
- Plastics & Phthalates ā A single conventional pad contains up to five plastic bags' worth of plastic. Phthalates are used to make these plastics flexible, but they are notorious endocrine disruptors that interfere with your hormones. Is Plastic In Pads Bad
- Dioxins ā These are highly toxic byproducts created during the chlorine bleaching process. Manufacturers bleach wood pulp to make pads look "clean" and stark white, leaving behind trace amounts of carcinogenic dioxins.
- Synthetic Fragrance ā "Odor-control" technology is just a trade secret cocktail of synthetic chemicals. Fragrances in pads are a leading cause of vulvar irritation, yeast infections, and allergic contact dermatitis. Are Scented Pads Bad
What to Look For
Green Flags:
- Totally Chlorine-Free (TCF) ā Guarantees no dioxins are created during the bleaching process.
- 100% Organic Cotton Core & Topsheet ā Ensures the material touching your body is free from pesticide residues.
- Bioplastic or Plant-based Backings ā Reduces your exposure to phthalates found in traditional petroleum-based plastics.
Red Flags:
- "Odor-Absorbing" or Scented ā Code for undisclosed synthetic fragrances and potential chemical allergens.
- Rayon or Wood Pulp Blends ā Highly processed synthetics that often require aggressive chemical bleaching.
- Unspecified "Leak-Proof" Layers ā Often achieved using PFAS or heavy conventional plastics that don't breathe.
The Best Options
If you want to avoid hidden chemicals, you need brands that prioritize total transparency and independent lab testing. Check our guide on the Safest Pad Brand for a complete breakdown of the market.
| Brand | Product | Verdict | Why |
|---|---|---|---|
| Natracare | Organic Cotton Pads | ā | Plastic-free, TCF, and lab-tested free of PFAS. Is Natracare Pads Clean |
| Rael | Organic Cotton Cover Pads | ā | Uses OCS-certified organic cotton without harsh chemicals. Is Rael Pads Clean |
| Cora | Organic Cotton Pads | ā ļø | Clean cotton, but their period underwear had a past PFAS detection. Is Cora Pads Clean |
| Always | Ultra Thin Pads | š« | Independent lab tests found they emit carcinogens like styrene. Is Always Pads Safe |
The Bottom Line
1. Ditch the conventional plastic pads. Brands like Always and Stayfree expose you to VOCs, phthalates, and synthetic plastics.
2. Never buy scented period products. Your vagina does not need to smell like an ocean breeze, and those fragrances cause extreme irritation.
3. Look for TCF organic cotton. Prioritize brands that use Totally Chlorine-Free bleaching and 100% organic cotton top sheets to avoid dioxins and pesticides.
FAQ
Are organic pads actually chemical-free?
Not always. An EPA-certified lab found PFAS in 13 out of 18 pads labeled as "organic" or "non-toxic." While organic cotton limits pesticide exposure, the leak-proof backings and adhesives can still contain forever chemicals. Are Organic Pads Worth It
Do panty liners have the same chemicals as pads?
Yes. Daily panty liners undergo the exact same manufacturing process as full-size pads. Wearing them every day means chronic, daily exposure to plastics, VOCs, and potential PFAS against highly absorptive tissue. Are Panty Liners Safe
Is period underwear safer than pads?
It depends on the brand. While period underwear eliminates disposable plastics, 65% of tested brands contained PFAS for waterproofing. You must choose strictly vetted, PFAS-free brands if you make the switch. Period Underwear Vs Pads
