The Lawsuit and Settlement

In 2020, a class-action lawsuit was filed against Thinx, claiming that the company's period underwear contained chemicals such as polyfluoroalkyl substances (PFAS), which could be harmful to human health. PFAS are a group of synthetic chemicals that have been associated with various health issues, including hormonal disruption, reproductive problems, and even cancer. The presence of these chemicals in Thinx products contradicts the brand's promise of offering a safe and sustainable alternative to traditional menstrual products.

After years of legal battles, Thinx has agreed to settle the claims by paying up to $5 million. This settlement includes a fund to compensate consumers who purchased Thinx underwear between November 12, 2016, and November 28, 2022.

The company has also pledged to improve its testing protocols and implement measures to ensure product safety in the future. People who submit a claim have options ranging from receiving a cash refund up to $21 to a voucher for 35% off future purchases.
