Period Underwear Without PFAS: The Ultimate Guide to Non-Toxic, Chemical-Free Protection


The Benefits of Non-Toxic Period Underwear: Say Goodbye to PFAS and Chemicals

For centuries, women have relied on various menstrual products to manage their periods. From cloth pads and tampons to menstrual cups and period underwear, the options are endless. However, with the rise of awareness around the potential health risks associated with traditional menstrual products, many women are looking for safer and nontoxic alternatives. This is where period underwear without PFAS comes in. In this article, we’ll discuss the benefits of choosing nontoxic period underwear and how it can provide a safer and more comfortable period experience.

When Thinx made its debut in the 2010s, it revolutionized the feminine hygiene industry by introducing reusable period underwear to the mainstream market. However, it was later discovered that the fabric used in Thinx products contained an alarming amount of per- and polyfluoroalkyl substances (PFAS). These chemicals are widely used due to their stain- and water-resistant properties, and are commonly found in various products such as rain jackets, non-stick cookware, and even organic pasta sauces. However, exposure to some types of PFAS, even in small amounts, has been linked to cancer and reproductive issues.

Given the vulva’s high absorption rate, it is crucial to choose period underwear that is not only absorbent but also free from harmful chemicals. Fortunately, the market now offers a plethora of natural and sustainable options that prioritize responsible sourcing, inclusive sizing, and ethical production. These period underwear choices not only offer a comfortable and secure fit, but also provide peace of mind knowing that they are free from PFAS and other harmful substances.

Whether you prefer to wear period underwear on its own or as a backup for leaks, there are many options available that will keep you feeling safe, secure, and sustainable.

What is PFAS and Why Should You Avoid It? & Why Choose Non-Toxic, Chemical-Free Period Underwear?

PFAS (Per- and Polyfluorinated Substances) a group of synthetic chemicals, commonly dubbed as “forever chemicals”, have a prolonged degradation process that can enter the human body through multiple channels, such as the nose, mouth, and skin. Overexposure to PFAS may result in health consequences, including hormone disruption, high blood pressure, cancer, and birth defects if exposed during pregnancy.

Consumers often face the responsibility of avoiding PFAS on their own. The Green Science Policy Institute says that Clothing that contains PFAS, such as rain gear, ski gear, athletic gear, and now, leakproof underwear, is usually waterproof yet breathable. Direct skin contact with PFAS is possible when wearing Thinx period underwear, increasing the risk of exposure.

Recent scientific research has provided evidence that being exposed to certain levels of PFAS could result in adverse reproductive effects such as reduced fertility or high blood pressure during pregnancy. Additionally, children may experience developmental delays or other effects, and there is an increased risk of certain cancers such as prostate, kidney, and testicular cancer. Furthermore, PFAS exposure may weaken the body’s ability to fight infections by impairing the immune system and interfering with the natural hormonal balance of the body. These are just a few of the potential health hazards associated with exposure to PFAS, as further research is still required to fully understand the extent of its impact on human health.

According to Marta Venier, PhD, an assistant professor at the School of Public and Environmental Affairs at Indiana University, Bloomington, “The concerning aspect is that these products come into contact with very sensitive parts of our bodies.” She added that the risk of dermal absorption is higher in these areas since they are more susceptible to absorption. However, researchers are uncertain about the most dangerous levels of PFAS or how much exposure time is necessary to pose a health risk.

Although the Environmental Protection Agency is attempting to limit PFAS exposure, it is still challenging to achieve. It is often recommended to avoid these chemicals completely, but that is easier said than done. Most companies do not test products for PFAS before releasing them to the public, making it difficult to ensure that garments or other items are safe.

As Professor Peaslee explained, PFAS can be intentionally or unintentionally added to products, and there is frequently no indication of their presence on the label. However, as soon as studies highlight their negative effects, there is a demand for products without PFAS.
