Interval underwear or interval panties are tremendous absorbent and a lifesaver for girls when their interval has come, however a few of them is also coated with persistent and hormone-disrupting per- and polyfluoroalkyl substances (PFAS) chemical compounds. The Mamavation neighborhood members requested us to start out testing “leak-proof” interval underwear to see if it had any traces of PFAS so we did.
And we have now continued to check for over two years. So which interval underwear is much less prone to be made with a PFAS coating and higher on your energetic life-style?
You’ve trusted Mamavation to carry you subjects like greatest unhazardous cookware, greatest air purifiers for the house and greatest natural mattresses, now be part of us for the perfect and worst unhazardous interval underwear with lab outcomes exhibiting that 65% of merchandise examined may very well be contaminated with PFAS. Scroll all the way down to the underside if you wish to see the uncooked information.

Interval Underwear Might Be Exposing Customers to Poisonous PFAS
In early 2020, Jessian Choy, a journalist at Sierra Journal (from the Sierra Membership) shared outcomes from the Laboratory of Utilized Nuclear Physics on the College of Notre Dame concerning potential PFAS contamination in the most well-liked interval underwear model — Thinx.
We interviewed Jessian Choy and she or he instructed us that after years of questioning if such a underwear contained a kind of PFAS chemical, she determined to enlist the assistance of Dr. Graham Peaslee, a fellow on the American Chemical Society and professor of Utilized Nuclear Physics. Dr. Graham Peaslee was additionally involved with the potential final result of PFAS in interval underwear after releasing comparable outcomes about American meals packaging.
Peaslee has been researching PFAS for the previous few years and was the scientist that found the presence of PFAS in fast-food wrappers in 2017. He’s additionally served as an envoy for the newly debuted movie starring Mark Ruffalo about PFAS referred to as “Darkish Waters,” by which he led a dialogue about PFOA at Notre Dame College.
The outcomes from these panties have been stunning as a result of they made it clear that merchandise like interval underwear may very well be manufactured with PFAS chemical compounds inside their “moisture-wicking” material and offered to unsuspecting American shoppers. Since your interval lingerie are proper up in opposition to the vagina, it’s an necessary dermal publicity because it lies cosy in opposition to the vulva for an prolonged time frame.
As a result of scientists are already involved about dermal publicity, it may very well be a really related avenue for poisonous air pollution into the physique.
After Dr. Peaslee discovered fluorine in Thinx panties and it was coated by the Sierra Journal, it was adopted by Thinx denying any accountability or risk that it was true. Thinx then employed consultants (who have been notorious for representing poisonous chemical firms and thwarting regulation and public coverage arduous on poisonous chemical compounds like perchlorate) to refute the findings of what Dr. Graham Peaslee present in his lab on the College of Notre Dame.
Shortly following the denial, Thinx modified the language on their web site to permit them to promote Individuals interval panties with PFAS with out stepping into scorching water. (We all know as a result of we checked.)
Mainly, any reference to the “PFAS” chemical class was eliminated, and as a substitute, they changed it with language that solely claimed they have been free from PFOA, which is one particular chemical inside the class. We additionally observed different manufacturers making comparable adjustments in authorized phrases on their websites, however not all.
So in different phrases, the manufacturers like Thinx haven’t modified their product, however they’ve modified the way in which they speak about their product. They aren’t telling you no PFAS chemical is current, they’re as a substitute telling you PFOA (one of many 1000’s of chemical compounds in that class) isn’t current. However clearly, there’s extra to fret about inside these panties than PFOA.
What in regards to the different 12,000+ PFAS chemical compounds? Shouldn’t we find out about these too? Mamavation reported on these findings in early 2020. Afterward, the neighborhood was very involved about this product class and requested us to start out testing completely different manufacturers of interval underwear to get a greater understanding of which manufacturers didn’t have any detectable fluorine.
So that is precisely what we did beginning in 2020 and you’re studying the outcomes of our privately commissioned examine at the moment. We’ve constantly added to this examine with further outcomes as they’re donated model new in packaging to us by followers.
Why PFAS Chemical substances Are Problematic Round Your Vagina
PFAS chemical compounds, in any other case often known as per- and polyfluoroalkyl substances (PFAS), have been dubbed “endlessly chemical compounds” due to their endurance. These chemical compounds are extraordinarily problematic to human well being and the atmosphere as a result of they’re persistent, which means they construct up and don’t go away. They resist degradation within the atmosphere they usually stay in our our bodies for YEARS after publicity, generally a long time.
“The truth that this can be a preventable publicity that accumulates within the physique, and younger child-bearing-age ladies are being uncovered has impacts not solely for individuals who use this underwear, but additionally doubtlessly for his or her future youngsters as a result of these compounds keep in our our bodies for years!” says Hannah Gardener, founding epidemiologist at Agreenslate.com and Advisor to Mamavation.
“These underwear with ‘endlessly chemical compounds’ have environmental implications from manufacturing to being washed in our washing machines all the way in which to the tip of their life cycle in landfills.”
Researchers are additionally very involved about dermal contact of PFAS and are frightened that the well being outcomes could also be much like ingestion. Subsequently, it’s necessary to keep away from PFAS as a lot as attainable across the vaginal space and another space as a result of it builds up within the physique.
In different phrases, they don’t seem to be rapidly excreted from our our bodies like different hormone-disrupting environmental contaminants. And that endurance has develop into a really huge deal in meals packaging, water … and now materials.
I extremely suggest watching Darkish Waters, a real story about PFAS chemical compounds contaminating small-town America starring Mark Ruffalo, Anne Hathaway and Tim Robbins. This brief trailer provides you with a fast understanding of what’s occurring round the USA to our water provide. And it’s fairly severe.
Potential Well being Results of PFAS Chemical substances From Analysis
PFAS (aka PFCs or perfluorinated chemical compounds, together with PFOA and PFOS) are added to many merchandise we buy to make them “stain-resistant,” “grease-proof” and “waterproof.” In meals packaging, they’re utilized in popcorn baggage, pizza containers, quick meals canisters and wrappers and the flat dish on the underside of truffles.
They’re additionally in carpeting, furnishings and clothes as “stain-proof” brokers. You may also discover them on nonstick pans, some tooth flosses and cosmetics. Right here is the listing of well being issues (PFAS) perfluorinated chemical compounds are linked with.

“These outcomes add to the rising physique of proof reaffirming that we have to know extra, not much less, in regards to the elements in interval merchandise. Hundreds of thousands use menstrual merchandise month-to-month.
It’s unacceptable that there are such a lot of unknowns in regards to the elements, security and well being impacts of merchandise that come into contact with one of the crucial delicate and absorbent elements of the physique,” stated Alexandra Scranton, Director of Science and Analysis at Girls’s Voices for the Earth (WVE), a nationwide environmental well being group, that has been advocating for ingredient transparency and security of interval care merchandise for the final decade.
“Moreover this new testing additionally exhibits that PFAS-free interval underwear is feasible. Which suggests, not solely are these chemical compounds including doubtlessly dangerous publicity to our our bodies and the atmosphere, however they’re additionally pointless to the efficiency and efficacy of those merchandise.”
For those who really feel such as you’ve been uncovered to PFAS, the Company for Poisonous Substances and Illness Registry, a division of Neighborhood Well being Investigations has created this reality sheet to make use of when speaking to your physician.
Why Are Manufacturers Claiming They Are PFAS Free When They Are Not?
We observed that some manufacturers have been making claims of being PFAS-free as a result of they use OEKO-TEX® licensed materials and have been beneath the impression that OEKO-TEX® means “PFAS-free.” We discovered this assumption NOT to be true. After discovering examples of OEKO-TEX® licensed interval panty materials testing for top ranges of fluorine, Mamavation determined to research additional.
We interviewed Ben Mead, Managing Director of Hohenstein Institute America, which is an organization that manages the OEKO-TEX® normal in the USA. Ben made it clear to us in an interview over the telephone that OEKO-TEX® checks for less than 30+ the most typical PFAS chemical compounds immediately like PFOA and they don’t take a look at their materials for fluorine in any respect.
As a result of OEKO-TEX® doesn’t take a look at their accredited chemical compounds for fluorine, we can’t be certain they don’t include any of the opposite 1000’s of PFAS chemical compounds they don’t seem to be testing for. It’s like a “take a look at no evil see no evil” sort of state of affairs.
OEKO-TEX® has added some further “PFOA-like” chemical compounds to their testing in 2021, however we’re nonetheless not satisfied they’re searching for each attainable PFAS chemical, particularly the “short-chain” ones. Subsequently any model that’s counting on OEKO-TEX® to make that declare, may very well be in for an enormous shock. Sadly, It’s not fool-proof as you’ll see within the outcomes we acquired.
As we have been interviewing manufacturers about this matter, it was clear to us that almost all of them weren’t even conscious you would take a look at for fluorine as a strategy to spot “short-chain” PFAS chemical compounds of their panties. The one trade excelling at testing for fluorine as a substitute of every PFAS chemical individually is the composting and meals packaging trade. Interval underwear firms must catch up.
Present Federal Testing Necessities Are Not Sufficient to Defend Households
Pete Myers, our fundamental scientific advisor, gave us an interview about what the issues are when it comes to how chemical compounds are evaluated on the Federal stage and the way that leaves HUGE gaps of considerations for households, notably ladies and kids.
Pete Myers reviewed three issues that exist that may be adjusted to make pregnant ladies and households safer. A lot of the issues are round how the chemical compounds are examined and controlled.
Low-Dose Testing of Chemical substances Isn’t Required by Feds and It Ought to Be
You understand that saying “dose equals the poison?” It’s the concept that chemical compounds are solely harmful at numerous doses inside your physique. Excessive doses might trigger loss of life so they’re usually averted, however what if low-doses might additionally trigger harm over time?
First, the Feds assumed that prime dose testing will inform them every thing they should find out about low-dose testing with out doing the low-dose testing. In accordance with Pete, they do the excessive dose testing after which extrapolate what they suppose will occur at low-doses. Nevertheless, nothing is definitely accomplished to have a look at these low-doses.
Whereas that works with some poisons based on Pete, it emphatically doesn’t for endocrine-disrupting compounds. And that’s as a result of completely different genes get turned on and off at completely different elements of the dose-response curve. What occurs at low-doses will be simply the other of what occurs at excessive doses. And due to the way in which they construction their checks, they by no means dose on the low ranges which might be related to most individuals’s expertise.
In different phrases, they actually don’t know what’s going to really occur. They’re guessing. Pete has written a number of scientific (and peer-reviewed) papers on this. And when he printed the second the nation’s high toxicologist, Dr. Linda Birnbaum, former director of the Nationwide Institute of Environmental Well being Sciences wrote an editorial concluding that this needs to be the overall expectation for endocrine-disrupting compounds.
Ought to low-dose testing be thought-about? I assume it relies on what your interpretation of “secure” is. For those who don’t need to know, don’t take a look at. For those who don’t take a look at low-doses, you positively gained’t perceive their impacts.
Solely the Lively Ingredient Is Analyzed to Decide Security Leaving Out Actual-World Exposures
Second based on Pete, when the Feds take a look at pesticides, they solely take a look at the energetic ingredient. They aren’t taking a look at our real-world publicity of an entire formulation, simply sure elements inside. And that’s additionally fully absurd. It’s like testing the tomatoes in a spaghetti sauce however lacking the oils, herbs and different elements.
Refusing to check your complete formulation means they don’t know the way it’s reacting along with your physique because it’s offered or utilized. The precise product accommodates a posh combination of different chemical compounds which might be included particularly to make the energetic ingredient extra poisonous. And it’s not simply pesticides which have this downside.
We dwell in a soup of nasties that may work together in ways in which dramatically make the combination extra harmful than only one chemical. Is that this poisonous soup secure? I assume it relies on what your interpretation of “secure” is. For those who don’t need to know, don’t take a look at the merchandise the way in which households expertise them of their houses.
The Feds Use Antiquated Testing As a substitute of Fashionable Testing to Consider Fashionable Chemical substances
Third based on Pete, the checks they use are manner old-fashioned. The Feds depend on antiquated testing in comparison with the instruments that unbiased scientists use when inspecting toxicity.
Right here’s Pete’s analogy: “Think about you’re an FDA worker and also you’ve simply seen pictures in Nationwide Geographic of distant galaxies taken by the Hubble House Telescope. You’ve by no means seen something prefer it. So what do you do? You seize your binoculars and go into your yard at evening, lookup towards the celebrities, and see nothing like these pictures. You don’t see something so that you conclude the pictures are FAKE NEWS.
One of many crude checks the EPA and FDA use was really developed within the Thirties. In case they didn’t know, medical science has superior quite a bit since 1935. Their checks are completely insensitive to what we have to find out about endocrine-disrupting chemical compounds. To find out what’s ‘secure’ it’s essential to use fashionable medical instruments.
Not surprisingly, they aren’t discovering something, so they can say ‘no hazard right here!’ However does that imply they’re proper? I assume this relies on what your interpretation of ‘secure’ is.”
Mamavation’s Investigation of Interval Panties and Interval Underwear
Mamavation examined the most well-liked interval panties (some as much as 4x) searching for fluorine, the chemical that unites all PFAS chemical compounds. That is necessary to know — as a result of there are millions of PFAS chemical compounds in commerce and most are usually not even attainable to seek out as a result of we shouldn’t have the checks accessible, we’re testing for fluorine as a substitute.
That is precisely what the meals packaging trade does to find out whether or not PFAS was “deliberately added” and will be composted or not. So this normal already exists in different industries and inside completely different state legal guidelines formulated round packaging and PFAS and generally is a helpful instrument to interval underwear firms when testing their very own merchandise for PFAS.
As a result of testing for fluorine is the one normal that’s on the market, we’ve tailored this to materials and are utilizing it for this investigation on interval underwear. BPI Industries makes use of the usual of 100 ppm of fluorine to find out if PFAS was deliberately added, so we’ve accomplished the identical.
Manufacturers with over 100 ppm of fluorine go into the “not our favourite” class, whereas manufacturers that take a look at between 0 ppm to 100 ppm can be within the “higher” class, and types that don’t have any fluorine residue can be within the “greatest” class.
Outcomes From Mamavation’s Research on Interval Panties
Be aware: [Updated With Additional Product Since Original Study Posted. Mamavation has accepted donations of brand new period underwear products and has continued to update this recommended list.
August 16, 2021: Mamavation added additional results from 2 period underwear brands bringing the total up to 19 period underwear products tested. UPDATED October 15th, 2021: Mamavation added 1 additional brand bringing total to 20 brands. Those new brands are marked with a *. UPDATED June 15th, 2022 Mamavation added 1 additional brand bringing the total to 21. UPDATED June 23rd, 2022 Mamavation added additional brands.]
Unique examine Might 24, 2021: Mamavation despatched 17 pairs of interval underwear from 14 manufacturers to an EPA-certified laboratory that used the dedication of whole fluorine by oxygen flask combustion and ion-selective electrode evaluation. The extent of qualification (LOQ) was 10 elements per million.
We didn’t take a look at panty liners, tampons, menstrual cups, interval swimwear or common underwear. We examined a bikini, briefs, waist bikini, high-waist, boxer briefs and tremendous hiphugger interval underwear marketed to accommodate heavier move days in sizes from XS to XXL. Listed here are the most important findings from our laboratory:
|
About 65% of the merchandise examined had detectable ranges of fluorine current in both the outer or internal layer of the crotch. Of the 17 pairs of interval underwear examined, 11 pairs had detectable fluorine current. |
|
35% of the merchandise examined did NOT have detectable ranges of fluorine current in both the outer or internal layer of the crotch. Of the 17 pairs of interval underwear examined, 6 merchandise didn’t include detectable ranges of fluorine. |
|
57% of interval underwear manufacturers examined had detectable ranges of fluorine current in both the outer or internal layer of the crotch. Of the 14 interval underwear manufacturers examined, 8 manufacturers had detectable ranges of fluorine current. |
|
3 manufacturers of interval underwear had ranges of fluorine over 100 ppm, with one as excessive as 940 ppm. |
|
2 manufacturers of interval underwear had merchandise with numerous ranges of fluorine detected so they’re discovered in several ranges of the investigation. |
|
7 manufacturers of interval underwear had merchandise with decrease ranges of fluorine current suggesting they might have been uncovered unintentionally from processing or from the packaging. |
|
6 manufacturers of interval underwear out of 14 manufacturers have been fully freed from detectable fluorine, suggesting PFAS chemical compounds are usually not wanted in interval underwear in any respect. (At the moment that quantity is larger!) |
Not Our Favourite Interval Underwear Manufacturers
These manufacturers examined at over 100 ppm of fluorine. We examined a number of varieties of manufacturers and retested several types of underwear for some manufacturers that ended up right here. The 100 ppm normal is identical normal used to find out if meals packaging is compostable. It’s not an ideal normal, however that is what we have now. Nevertheless, we make no claims as to how a lot fluorine is harmful vs. secure for dermal publicity in your vaginal space. We merely have no idea.
- Thinx Boyshort — 619 ppm fluorine
- Thinx Excessive Waist — 940 ppm fluorine
- Thinx BTWN — 132 ppm fluorine
- Knix Excessive Rise — 373 ppm fluorine
- Proof Hipster — 234 ppm fluorine
Higher Interval Underwear Manufacturers
Fluorine was discovered however beneath 100 ppm. That particular stage is identical normal to find out whether or not meals packaging is compostable, so we’re utilizing it right here for comparable functions. Nevertheless, we make no claims as to how a lot fluorine is harmful vs. secure. We merely have no idea.

Cora — 14 ppm and 13 ppm natural fluorine* (new model added) |
|
Knix Boyshorts — 43 ppm fluorine |
|
Knix Excessive Waisted Interval Underwear — 17 ppm fluorine (new outcomes added) |

|
Thinx Converse Excessive Waist — 10 ppm fluorine |
|
Victoria’s Secret — 20 ppm and 12 ppm fluorine |
Finest Interval Underwear Manufacturers
Mamavation used an EPA-certified lab to do that testing. No fluorine was detected in any of those merchandise despatched to the lab in 2020 and 2021. The Degree of Qualification (LOQ) for testing was 10 elements per million, subsequently if merchandise had fluorine at decrease ranges, the take a look at wouldn’t discover it. We can not assure these manufacturers will proceed to check the identical.
This was solely a snapshot in time to assist information you in purchases. Most manufacturers are utilizing a skinny layer of polyester or nylon to seize as much as 5 tampons’ price of heavy move and maintain it in your panties.
