If you purchased Thinx Period Underwear, you may be entitled to some money back in a class action settlement.
Thinx is a brand that sells period-proof underwear that are designed to be super absorbent — so you can wear them instead of, or in addition to, pads or tampons.
In May 2022 a class action lawsuit was filed against Thinx, in which the brand was accused of having harmful chemicals in their underwear. Thinx admits no wrongdoing but has settled the case by paying their customers $5 million.
Here’s everything to know about the Thinx lawsuit and if you’re eligible for a payout with the class action settlement.
Thinx was accused of deceptive advertising — but not of causing any physical harm.
According to the class action complaint, customers say that the company falsely advertised their period-proof underwear as being safe and free of harmful chemicals. An attorney representing the plaintiffs says that the case is focused on the company’s marketing and not on any personal injury claims related to the product.
The attorney said that customers would not have bought the product if they knew it contained harmful chemicals like polyfluoroalkyl substances (‘PFAS’) — “which are a safety hazard to the female body and the environment.”
According to the class action settlement, going forward Thinx will:
- Take measures to help ensure that PFAS aren’t intentionally added to Thinx Period Underwear products and will maintain reviews to ensure this.
- Continue to have suppliers of raw materials for Thinx Period Underwear review and sign a Supplier Code of Conduct and Chemical Supplier Agreement declaring that PFAS are not intentionally added to Thinx Period Underwear.
- Disclose the use of antimicrobial treatments on their website and will not to refer to the antimicrobial components of Agion as “nonmigratory.”
Thinx is accused of containing ‘forever chemicals.’
Some of the chemicals allegedly found in Thinx period underwear are “forever chemicals” or “long-chain” chemicals, often called PFAS. The full long-term impacts of PFAS exposure aren’t yet known and are still being studied.
The CDC says that PFAS are pretty much everywhere and can stick around in our bodies if we’re exposed to them a lot. They can be found in blood, food, and the environment. The Agency for Toxic Substances and Disease also mentions that being exposed to PFAS can lead to some health problems like kidney cancer, higher cholesterol, and even make vaccines less effective.
