Context:

A recent study has revealed alarming levels of toxic PFAS chemicals in some reusable menstrual products such as pads and period underwear, raising concerns about their safety. These 'forever chemicals,' known for their persistence in the environment and potential health risks, were found in both ionic and neutral forms, with neutral PFAS being less understood but potentially more harmful due to their ability to be absorbed through the skin. Despite these findings, the presence of PFAS was not universal across all products, indicating that they are not essential for manufacturing these items. The study highlights the need for greater transparency and regulation in the production of menstrual products, as well as further research into the absorption and long-term effects of PFAS on health. Consumers are largely unaware of the presence of these chemicals due to the lack of labeling, posing a significant challenge for informed decision-making concerning eco-friendly menstrual products.

Dive Deeper:

• Extremely high levels of PFAS, particularly in their neutral form, were detected in reusable menstrual products, which are gaining popularity for their eco-friendly appeal. Neutral PFAS are harder to detect but can be absorbed through the skin and mucous membranes, posing potential health risks.

• PFAS chemicals, known for their persistence and potential to cause various health issues such as cancer and hormone disruption, were found in concentrations as high as parts per million, significantly higher than previously measured ionic PFAS.

• The study, which analyzed 59 products, including period underwear and reusable pads, found that a substantial portion had intentionally added PFAS, likely for leak prevention, although these chemicals are not necessary for product function.

• The lack of labeling on products containing PFAS means consumers are unaware of their exposure to these chemicals, complicating efforts to make informed choices about environmentally friendly menstrual products.

• Neutral PFAS have not been well studied, and there are currently no regulations specifically addressing them, underscoring the critical need for more research and regulatory oversight in the manufacturing of menstrual products.

• The study suggests a broader need for transparency and regulation around materials used in menstrual products, as many users, including teens and adults, seek safer and environmentally friendly options.

• Despite the presence of PFAS in some products, the study's findings also offer hope, as not all products contained high levels of these chemicals, suggesting that safer manufacturing processes are possible and should be pursued.
