Common Ingredients In Period Products
There are a host of chemicals commonly found in tampons, pads, liners, and period underwear, such as:
- Dioxins or Persistent Organic Pollutants – this is from chlorine processing (Note: there are NO safe levels of dioxin since they can disrupt hormones and impact immune system function) 
- Chlorine – used in the bleaching process
- Rayon – commonly associated with an increased risk of Toxic Shock Syndrome 
- Most coventional pads and tampons are made from synthetic rayon
- Genetically modified cotton – the majority of cotton grown in America is genetically modified
- Undisclosed Synthetic Fragrance or Parfum

- Pesticide Residues

- Dyes, like Titanium Dioxide – may be linked to reproductive damage 
- Volatile Organic Compounds (VOCs) – may damage the kidneys, liver, and central nervous system [3, 4]
- Polyacrylate Foam
- Polyethylene, Polypropylene
- Thermoplastic Polymer Adhesives
- Plasticizers, like Phthalates 
- Furans – similar to dioxins [6, 7, 8]
- Triclosan – an antibacterial
- BPA & BPS-alternatives – for plastic applicators
- Toluene

- PFAS or Forever Chemicals
- Certain absorbent period underwear brands, such as Knix Wear, were sued for potentially containing forever chemicals, despite marketing themselves as PFAS-free. Thinx has also faced class action lawsuits.

With a woman using about 10,000 tampons in her lifetime, these chemical exposures add up. Many of these chemicals are even reproductive toxins. Very ironic when it’s used directly for our reproductive systems!
On average, a woman will use about 10,000 tampons in her lifetime.
Regulations In Period Products
Menstrual products, like pads, tampons, and menstrual cups, are regulated by the United States Food & Drug Administration (FDA) as Class II medical devices. This class means that the devices are of “moderate to high risk.” Other feminine hygiene products, like wipes & washes, are only considered cosmetics.
Despite the fact that many tampons on the market contain potentially harmful ingredients, the FDA does NOT require that manufacturers list all ingredients. While tampons are legally required to warn consumers about Toxic Shock Syndrome (TSS), labeling requirements for ingredients are slim to none.
The FDA does NOT require ingredient labels on period products.
Manufacturers of tampons classified as medical devices are required to submit a pre-market notification called a 510(k) form to the FDA stating that the product is “safe to use.” This process (thankfully) requires manufacturers to include material safety testing, microbiological testing, and absorbency testing, however labeling is weak.
The regulation states that the FDA “recommends that manufacturers include a warning statement about allergic reactions and irritations” for scented products. However, this is recommended (keyword)!
In fact, the guidance says the following:
|“FDA’s guidance documents, including this guidance, do not establish legally enforceable responsibilities. Instead, guidances describe the Agency’s current thinking on a topic and should be viewed only as recommendations, unless specific regulatory or statutory requirements are cited. The use of the word should in Agency guidances means that something is suggested or recommended, but not required.” |
Gaps In The Law
Luckily, New York State passed a 2019 law requiring that manufacturers disclose all intentionally added ingredients on menstrual product labels. This is a great step in the right direction since the NY law is impacting the whole nation, but we need federal-level regulations! 
The New York law is certainly not perfect, since many period product ingredient labels are still very vague. Manufacturers oftentimes do not fully disclose the adhesive ingredients they use, nor the types of ink.
Lack of transparency is a major issue in the menstrual health space.
Are Menstrual Cups Safe?
While menstrual cups are extremely sustainable, caution is needed. Menstrual cups are made from silicone, which is a polymer made from siloxane. Silicone is a type of plastic. It’s been shown that silicone may degrade over time, especially in warm/heated conditions. [12, 13, 14, 15,16, 17] Whether the silicone weakens or leaches inside a warm human body is still undetermined, but more studies are needed.
Like tampons, menstrual cups are linked to Toxic Shock Syndrome, since they can create a breeding ground for Staphylococcus aureus bacteria, so they’re not necessarily much safer.  There are also some rumors that menstrual cups may contain unintentional levels of heavy metals.  While this information isn’t confirmed, I like to err on the side of caution.
If you do opt for a menstrual cup, washing it off with soap and water will not cut it. It must be properly boiled and sterilized before every reinsertion! Opt for high-quality, food-grade, or medical-grade options only if absolutely needed.
How To Choose Nontoxic Period Products
Look for the following when shopping for low-tox menstrual hygiene products:
- Unbleached 100% organic cotton throughout (or at minimum, organic cotton cover for pads & liners)
- Dye-free or colorant-free
- Free of Titanum Dioxide
- Note: many brands label chlorine-free to make it seem healthier than it is. While you definitely should opt for chlorine-free brands, this term on its own does not mean it’s necessarily healthy.
- Full ingredient labels with the chemical names & function listed
- Avoid products that contain plastic (like polypropoylene, polyethylene, and polyester – mostly for tampons, since they’re inserted into your body)
- PEG-free (which may be contaminated with 1,4 dioxane or ethylene oxide)
To minimize the potential of Toxic Shock Syndrome (TSS), a rare but serious disease, it’s best to avoid tampons altogether. Yes… I know, this isn’t always possible, so when you need one, opt for the lowest absorbency and change it every four hours. While tampons are discrete and convenient, they’re not the only way. Always wash your hands thoroughly before and after. Using tampons for under 4 hours does not eliminate your risk of TSS. If you prefer tampons, cardboard applicators (or no applicator at all) will decrease your exposure to BPA and BPA alternatives.
And most importantly… never wear tampons when going to bed!
Additionally, it’s best to avoid most period underwear on the market – many have been shown to contain forever chemicals.
Safer Non-Toxic Period Products
Vaginal walls are very permeable, which means any chemicals that come into contact with it can be absorbed into the bloodstream. Check out the below best, better, & worst period product options.
Best – Opt For These!
Note: since pads are not going directly into your body, it’s less crucial that they’re 100% non-toxic since the adhesive is likely not going directly on your skin. For most people, these are perfectly safe.
- Natracare – do not disclose glue polymer
- Cora – contains polyethylene and polyester (for backsheet & acquisition layer), polypropylene (on wings), and undisclosed polymers/adhesive
- Lola – do not disclose bioplastic backsheet or adhesive ingredients
- Rael – contains polyethylene and polypropylene, undisclosed polymers, and undisclosed adhesive.
- Viv – do not disclose polymer or adhesive (code inonaround saves you 15% off your order!)
- Honey Pot – contains undisclosed polymer core with polyethylene and polypropylene backing [ONLY opt for non-herbal options without fragrance]
- Natracare [opt for cardboard applicator instead of plastic]
- Lola [opt for cardboard applicator instead of plastic]
- Rael [opt for cardboard applicator instead of plastic]
Many brands also offer applicator-free tampons. These are great alternatives, as long as your hands are thoroughly washed.
- Natracare – do not disclose glue polymer
- Cora – contains polyethylene and polyester (for backsheet & acquisition layer) and undisclosed polymers & adhesive.
- Lola – do not disclose bioplastic backsheet or adhesive ingredients
- Rael – contains polyethylene (for backsheet) and undisclose adhesive
- Viv – do not disclose polymer or adhesive(code inonaround saves you 15% off your order!)
- Honey Pot – contains undisclosed polymer core with polyethylene and poplypropylene backing [ONLY opt for non-herbal options without fragrance]
- Bambody – this brand doesn’t contain any PFAS and is OEKO-TEX certified.

The bottom line: beware of the potential hidden toxins lurking in period products. Regulations on menstrual health products are different per country, so make sure you do your due diligence for your specific area.  When in doubt, opt for 100% organic cotton pads when possible.
