Most women use sanitary pads every month without ever questioning what they are made of. They are often marketed as “soft,” “cotton-like,” and “safe.” But what is actually inside them?
Recent studies have found that some feminine hygiene products may contain chemicals of concern, including PFAS, often called “forever chemicals” because they can remain in the body and the environment for a long time.
As a result, more consumers are researching safer period care alternatives, including reusable pads and period underwear.
The Hidden Concern: Endocrine-Disrupting Chemicals in Menstrual Products
The feminine hygiene market is a multi-billion-dollar industry, yet product transparency remains limited. Many consumers still do not know what materials are used in conventional pads and tampons.
Scientific studies have identified trace levels of certain chemicals in some menstrual products, including:
- Phthalates – commonly associated with plastics
- Bisphenols (such as BPA) – used in polymer materials
- Parabens – widely used as preservatives
- PFAS – often referred to as “forever chemicals”
Vaginal and vulvar tissue is more absorbent than regular skin, which is why material safety in period care products matters so much. Consumers are increasingly paying attention to what touches their most sensitive areas.
Why PFAS in Pads and Tampons Is Raising Concern
PFAS are often discussed because of their persistence. These chemicals do not break down easily and may remain in the body and environment for years.
Public concern around PFAS in sanitary pads and PFAS in tampons has grown because these substances have been associated in broader research with hormone disruption, fertility concerns, immune system effects, and certain cancers.
This has led many women to question whether conventional disposable products are the best long-term choice.
Environmental Impact
The issue is not only personal health. Disposable period products also create a major environmental burden.
On average, a person who menstruates may use thousands of pads or tampons in a lifetime. Many disposable pads are made largely with plastic-based materials, and many tampons also include plastic applicators and plastic packaging.
Over time, this creates a significant amount of waste. Used products can remain in landfills for centuries, and improperly discarded items may pollute beaches, waterways, and oceans.
In short, products designed for a natural monthly cycle can contribute to a long-term waste problem.
Why Most Brands Do Not Talk About What Is Inside Sanitary Pads
One of the biggest issues in the menstrual care market is lack of transparency.
In many regions:
- Brands are not required to disclose full ingredient lists
- Manufacturing processes are not clearly explained
- Independent testing data is rarely shared openly
As a result, many consumers rely on marketing language instead of verified product information.
Why More Women Are Switching to Reusable Period Products
More women are now exploring reusable period care options such as:
Reusable Pads
- Period underwear
Common benefits include:
- Reduced waste
- Long-term cost savings
- More control over materials
- Greater product transparency
Are Reusable Period Products Safer?
Reusable period products can be a better option when they are made with the right materials and manufacturing standards.
When evaluating safe reusable period products, look for:
- Certified safe fabrics such as OEKO-TEX® certified materials
- No added fragrances
- Durable, washable construction
- Reliable leakproof layers
The Future of Period Care
The future of menstrual care is moving toward:
- Greater transparency
- Safer material selection
- Sustainable product design
Consumers are no longer satisfied with vague claims. They want to know exactly what they are using, why it is made that way, and whether it is better for both the body and the environment.
Conclusion
As awareness grows around chemicals in sanitary pads, PFAS in menstrual products, and the environmental impact of disposable period care, more consumers are rethinking their options.
Reusable alternatives such as period underwear and reusable pads are gaining attention because they offer greater material transparency, lower waste, and more control over what comes into contact with the body.
