The lawsuit, first filed in 2019, claimed that third-party lab testing found short-chain per- and poly-fluoroalkyl substances (PFAS) in Thinx underwear. PFAS are known as “forever chemicals” and have been linked to serious health risks. In the lawsuit, Thinx is being accused of not telling customers about the possible health risks that these products pose.
The Thinx lawsuit settlement agreement states that those who purchased a pair of period underwear from the company between November 12, 2016, and November 28, 2022, can claim a $7 USD refund per purchase, for up to three pairs of underwear, if they have the receipt. Those who do not have a proof of purchase receipt will receive a $3.50 USD cash refund per pair of underwear, up to a maximum of three pairs.
Thinx has denied all allegations made by the lawsuit, stating on Twitter, “We can confirm that PFAS have never been part of our product design. We will continue to take measures to ensure that PFAS are not added to our products…”
While the settlement does not admit Thinx’s wrongdoing, it is an important step toward ensuring customers have access to safe and sustainable menstrual products. In light of this lawsuit, other companies that make menstrual underwear, such as Knix and Aisle, have taken steps to ensure that their third-party textile suppliers do not use PFAS in the fabrics they supply.
I am not a professional regarding PFAS, however, what I will take away from this whole ordeal is how important it is to do your own research and stand up for what is important to you and your family. I am making an effort to be more diligent about the products I use but I am very aware that chemicals and health risks are all around us every day
