Thinx Class Action Lawsuit

In January 2023, it was reported that a class action lawsuit was filed against Thinx. The lawsuit alleged that the brand’s period underwear contained poly-fluoroalkyl substances, also known as PFAs, harmful chemicals that have been linked to fertility issues and certain cancers. Thinx settled the lawsuit out of court and denied the allegations that their underwear product contains PFAs. Per the official settlement website, which you can find here, “The proposed settlement is not an admission of guilt or wrongdoing of any kind by Thinx.” In addition, Thinx posted the following statement on its website:

“Thinx takes consumer health and product safety seriously, and we can confirm that PFAS has never been part of our product design and we have always prohibited our suppliers from using PFAS.

Thinx takes measures to help ensure that per- and polyfluoroalkyl substances (“PFAS”) are not intentionally added to Thinx period underwear at any stage of production. These measures will entail maintaining production controls, including material reviews.

Thinx ensures suppliers of raw materials for Thinx period underwear review and sign a Supplier Code of Conduct and Chemical Supplier Agreement, which require suppliers to attest that PFAS are not intentionally added to Thinx period underwear.”
