Period Underwear in Singapore: Exploring the Risks of PFAS and the Thinx Lawsuit Settlement

Period Underwear in Singapore: Exploring the Risks of PFAS and the Thinx Lawsuit Settlement

Ladies, have you switched to period underwear for comfort and environmental reasons? Before you do, read about the potential risks of PFAS and the Thinx lawsuit settlement. Learn how to protect your health and make an informed decision. #periodunderwear #healthrisks #PFAS #Thinxlawsuit #Singapore

Period underwear has become popular for women seeking a more comfortable and environmentally friendly option. However, recent news of a Thinx lawsuit settlement has raised concerns about the safety of period underwear, particularly about toxic substances like per- and polyfluoroalkyl substances (PFAS). This article will explore the safety of period underwear in Singapore and what we need to know about PFAS, the “forever chemical” behind the Thinx lawsuit.

Is period underwear in Singapore safe?

There is currently no peer-reviewed scientific publication on the measurement of PFAS in period underwear. Any reports of PFAS in period underwear found in the public domain may be related to investigations performed by independent organizations.

However, the presence of PFAS in period underwear may be related to stain-resistant fabric or other similar materials used in its manufacturing, according to Professor Eric Chan, a pharmaceutical scientist at the National University of Singapore’s Department of Pharmacy said. More research is needed to determine how much PFAS is absorbed by the skin in the vaginal area.

Because there is no regulation on the level of PFAS in period underwear, it is difficult for consumers to select PFAS-free products over the counter. Consumers need more knowledge about what products they can buy that are free of PFAS.

The ‘forever chemical’ behind the Thinx lawsuit

PFAS are a group of man-made chemicals used in various consumer and industrial products for decades. They are commonly found in products designed to resist water, oil, and stains, as well as heat-resistant and non-stick. Some examples of everyday products that might contain PFAS include non-stick cookware, waterproof clothing, carpets, food packaging, and menstrual products.

PFAS can be absorbed through the skin and has been detected in human blood and breast milk. In the industry, they are known as “forever chemicals” because they persist in the environment. They do not break down easily and can accumulate in the body over time.

According to American activist group EWG, PFAS “cause harm to the environment and human health, even at low levels”. Some research supports this statement, including a 2019 review of the substances’ impacts on cancer, immune function, metabolic outcomes, and neurodevelopment. EWG identified links between PFAS exposure and high cholesterol, pregnancy-induced hypertension and preeclampsia, testicular cancer, kidney cancer, and thyroid disease.

In response to the Thinx lawsuit, Thinx has announced that it will be transitioning to a PFAS-free coating in its products. Uniqlo, which carries a small range of Airism Absorbent Sanitary Shorts, has also removed PFAS and other hazardous chemical substances from its processes.

While more research needs to be done on the safety of period underwear, consumers should be aware of the potential presence of PFAS in such products. The lack of regulation on PFAS in period underwear means that consumers need more information and knowledge to select PFAS-free products over the counter.
