As a fast refresher, the interval underwear producer, Thinx Inc., not too long ago settled a category motion lawsuit that alleges Thinx’s advertising claims had been deceptive. Prospects who purchased the underwear inside a sure window of time can submit for a refund or voucher from Thinx, however the firm denies the allegations within the lawsuit and burdened that the settlement just isn’t an request for forgiveness or wrongdoing.
With all of that happening, we talked with Kelly Johnson-Arbor, MD, FACEP, FUHM, FACMT, a medical toxicologist and co-medical director of the National Capital Poison Center in Washington, DC, to search out out what these regarding chemical compounds are, the well being dangers they pose, and the way frightened we should always all be about our interval underwear.
So, what chemical compounds are in interval underwear?
Chemical substances have been present in different manufacturers of interval underwear, as nicely, and a number of the firms additionally use comparable language, equivalent to, “pure,” “non-toxic,” or “sustainable,” to explain their merchandise. Confusion in regards to the security of interval underwear has to do with per- and poly-fluoroalkyl substances (PFAS) additionally referred to as “eternally chemical compounds” being detected within the materials. PFAS are artifical supplies which might be used to make coatings and merchandise that resist stains, grease, warmth, oil, and water. They’re in clothes, furnishings, adhesives, and non-stick cooking surfaces, based on the Centers for Disease Control and Prevention (CDC).

“PFAS are utilized in takeout containers, stain-resistant materials, and cosmetics. The chemical composition of PFAS compounds consists of fluorine and carbon atoms which might be bonded collectively and are very proof against breakdown,” says Dr. Johnson-Arbor.
Not solely do PFAS cling round within the atmosphere, just about eternally, however additionally they construct up in fish and wildlife and may transfer via soils and contaminate consuming water sources.
What are the well being dangers of PFAS?
Persons are uncovered to PFAS by consuming contaminated food or water, based on the CDC, and probably through the use of merchandise that include PFAS. Well being dangers from publicity to low environmental ranges are unsure, however research of laboratory animals given giant quantities of PFAS present that development and growth could also be affected. PFAS may have an effect on the immune system, reproductive well being, thyroid operate, and the liver.
PFAS publicity has additionally been related to most cancers. “Many individuals understandably need to keep away from extreme PFAS publicity, together with from PFAS present in interval underwear,” Dr. Johnson-Arbor says. “Whereas there is no such thing as a proof that PFAS present in interval underwear are instantly liable for any undesirable well being situations, the additive results of PFAS exposures from a number of completely different sources could also be harmful for our well being general.”
After all, animal research aren’t the identical as human ones, so it may be tough to make a connection between the outcomes of animal research and human well being outcomes. “For PFAS, even a number of the human research have been inconclusive,” Dr. Johnson-Arbor says. “Since virtually one hundred pc of individuals residing in developed international locations have detectable ranges of PFAS of their bloodstreams, it’s difficult to find out precisely what antagonistic well being results are attributable to PFAS and never one other chemical or environmental publicity.”
How do I do know if my interval underwear is protected from PFAS?
Period products are regulated by the U.S. Food and Drug Administration (FDA). Although relying on a product’s classification, the producers could not embody all of the supplies used. You continue to need to assessment the product labels and the producer’s web site to see what else you’ll be able to be taught in regards to the elements concerned.
“Merchandise which might be marketed as being waterproof (a top quality that’s extremely fascinating in interval underwear) are prone to include PFAS or comparable substances. Even when a particular product is licensed as being PFAS-free, these chemical compounds might nonetheless be unintentionally launched into the underwear via the manufacturing or packaging course of, on condition that PFAS are discovered so extensively all through the atmosphere.” Dr. Johnson-Arbor says. “It’s necessary to do not forget that PFAS are all over the place and almost unimaginable to keep away from in our every day lives. We don’t totally perceive all of the potential well being results of PFAS.”
A priority with PFAS and interval merchandise is that the vaginal space is extremely delicate and could be absorbent. “There is no such thing as a proof connecting PFAS publicity in interval underwear to any antagonistic well being results, and from a medical toxicology perspective it’s protected to put on interval underwear due to this,” Dr. Johnson-Arbor says. “Interval underwear must be washed between makes use of and a few producers even advocate washing the underwear earlier than its preliminary use. It’s doable that the washing course of will lower the PFAS content material, making absorption even much less seemingly.”
The category motion grievance additionally alleges that Thinx underwear accommodates metallic nanoparticles used to deodorize clothes and may simply enter the physique. Nanoparticles are small particles that may be composed of various substances together with carbon, polymers, or metals, and are utilized in every day objects like toothpaste and cosmetics. “Metallic-based nanoparticles are additionally utilized in drugs resulting from their antimicrobial actions and are additionally added to toys and materials for this similar objective,” Dr. Johnson-Arbor says. “There are not any ailments which might be conclusively linked to metallic nanoparticle publicity. Nonetheless, as a result of they’re so small, nanoparticles can enter the physique and probably trigger DNA injury, hormonal imbalance, and immune system dysfunction.”
There will not be sufficient proof to help that interval underwear is unsafe, however is there sufficient knowledge to point out that it’s not? Till there are additional research or rules, it could come down to non-public alternative, and no matter brings you peace of thoughts.
