Avoid Microplastics

The controversy surrounding Thinx period underwear and the presence of per- and polyfluoroalkyl substances (PFAS) has sparked widespread concern among consumers. This article delves into the complex issue, examining the allegations, the company’s response, and the broader implications for menstrual product safety.

Understanding PFAS

PFAS, often referred to as “forever chemicals,” are a group of synthetic compounds used in various consumer products for their water-resistant and stain-repellent properties. These chemicals have come under scrutiny due to their persistence in the environment and potential health risks.

Health Concerns

Exposure to high levels of PFAS has been linked to several health issues, including:

• Developmental delays in children
• Increased risk of certain cancers
• Higher risk of obesity and high cholesterol
• Fertility problems in women
• Hormone disruption
• Increased high blood pressure during pregnancy

While the exact level of exposure leading to these health outcomes is not yet fully understood, the presence of PFAS in intimate products like period underwear has raised significant concerns.

The Thinx Controversy

In 2020, an article published in Sierra magazine brought attention to the potential presence of PFAS in Thinx period underwear. This led to multiple lawsuits against the company, which were eventually consolidated into a class-action lawsuit.

Testing Results

Dr. Graham Peaslee, a physics professor at the University of Notre Dame specializing in PFAS research, conducted tests on Thinx products. His findings indicated “high levels” of PFAS, particularly in the inner layers of the underwear’s crotch area.

Lawsuit Allegations

The plaintiffs in the lawsuit alleged that the presence of PFAS contradicted Thinx’s marketing claims that their products were “nontoxic, harmless, sustainable, organic, environmentally friendly, and otherwise safe for women and the environment”. They further claimed that the company knowingly concealed and misrepresented the true nature of their underwear.

Thinx’s Response

Thinx has consistently denied the allegations and maintains that their products are safe. In response to the controversy, the company has taken several steps:

1. Settlement: In November 2022, Thinx reached an agreement to settle the class-action lawsuit for up to $5 million, without admitting any wrongdoing.
2. Marketing Changes: The settlement requires Thinx to make changes to its marketing practices.
3. Product Safety Commitment: Thinx has stated that PFAS are not part of their product design and that they require suppliers to sign agreements attesting to the exclusion of these substances.
4. Third-Party Certification: The company claims their underwear is certified based on the STANDARD 100 by OEKO-TEX® and complies with OEKO-TEX® 100 Class II, Annexure IV standards.
5. Additional Testing: Thinx reports that they test finished products through an accredited third-party laboratory to ensure compliance with U.S. and international regulations.

The Challenges of PFAS Detection

One of the key issues in this controversy is the difficulty in definitively determining the presence of PFAS in products. There are several reasons for this:

1. Numerous PFAS Variations: There are approximately 9,000 different PFAS compounds, making comprehensive testing challenging.
2. Limited Testing Standards: Current certifications like OEKO-TEX® only test for about 30 PFAS in textiles, not all 9,000 known variations.
3. Lack of Labeling Requirements: In the United States, manufacturers are not required to identify PFAS on product labels.
4. Evolving Research: As new PFAS compounds are developed and identified, testing methods must continually adapt.

Consumer Concerns and Actions

The Thinx controversy has left many consumers wondering about the safety of their menstrual products. Here are some steps individuals can take:

1. Research Alternative Products: Look for brands that explicitly state their products are PFAS-free and provide third-party testing results.
2. Check for Certifications: While not comprehensive, certifications like OEKO-TEX® can provide some assurance of product safety.
3. Contact Companies Directly: Ask manufacturers for detailed information about their testing processes and PFAS policies.
4. Stay Informed: Keep up with the latest research and regulatory developments regarding PFAS in consumer products.

The Broader Impact on the Menstrual Product Industry

The Thinx lawsuit has had ripple effects throughout the menstrual product industry:

1. Increased Scrutiny: Other period underwear brands are facing similar questions about the presence of PFAS in their products.
2. Consumer Awareness: There is growing awareness among consumers about the potential presence of harmful chemicals in menstrual products.
3. Industry Response: Some companies are proactively addressing PFAS concerns by enhancing their testing and transparency practices.
4. Regulatory Pressure: The controversy may lead to increased regulatory scrutiny of PFAS in feminine hygiene products.

The Future of PFAS Regulation

As awareness of PFAS-related health concerns grows, there is increasing pressure for more comprehensive regulation:

1. State-Level Action: Some U.S. states have taken steps to restrict the use of PFAS in various products.
2. Federal Considerations: While PFAS are not currently banned at the federal level in the U.S., there is ongoing discussion about potential nationwide regulations.
3. International Efforts: Various countries and regions are implementing or considering stricter controls on PFAS use in consumer products.

Alternatives to Thinx

For consumers seeking alternatives to Thinx, there are several options available:

1. Other Period Underwear Brands: Research brands that explicitly state they are PFAS-free and provide third-party testing results.
2. Reusable Cloth Pads: These can be a PFAS-free alternative, but consumers should still verify the materials used.
3. Organic Disposable Products: Look for certified organic tampons and pads that are free from synthetic materials.
4. Menstrual Cups: Made from medical-grade silicone, these are typically PFAS-free but should still be verified with the manufacturer.

Conclusion

The question of whether Thinx underwear contains PFAS remains complex. While the company denies intentionally adding PFAS to their products, independent testing has suggested their presence. The settlement of the class-action lawsuit has brought about changes in marketing practices and renewed commitments to product safety from Thinx.

This controversy highlights the broader issues of PFAS in consumer products, particularly those marketed towards women. It underscores the need for more comprehensive testing methods, stricter regulations, and greater transparency from manufacturers.

As research continues and awareness grows, consumers are encouraged to stay informed, ask questions, and make choices that align with their health and environmental concerns. The menstrual product industry is likely to see ongoing changes as it adapts to these evolving consumer demands and potential regulatory shifts.

Ultimately, the Thinx controversy serves as a reminder of the importance of scrutinizing the products we use most intimately. It calls for a balance between innovation in menstrual products and ensuring the utmost safety for consumers and the environment.
