    Are you looking for period underwear made without added PFAS? In a world where fashion meets functionality, the choices we make regarding our clothing extend far beyond style. From comfort to performance, there are lots of factors that influence our buying decisions. But have you ever considered the potential impact of perfluoroalkyl substances (PFAS) on the items you wear every day?  

    Polyfluoroalkyl Substances (PFAs) in Everyday Life

    Per- and polyfluoroalkyl substances (PFAS) are a group of synthetic chemicals that have garnered attention recently due to their prevalence in consumer products, including textiles. Their unique oil, dirt and water repellant properties make them incredibly useful in products like non-stick cookware, upholstery, and water-repellant textiles.

    However, research has indicated that PFAS are harmful chemicals that can accumulate in the environment and our bodies over time. They have been detected in water sources, leading to potential contamination of drinking water.  
    Prolonged exposure to PFAS has been associated with adverse health effects, including reproductive issues, developmental problems in kids, and certain types of cancers. Exposure to PFAS is potentially linked to period irregularities, high blood pressure in pregnant people, and the risk of low birthweights in babies exposed while in utero.
    Although studies are ongoing, the recent surge in discussions around the presence of PFAS in clothing is a reminder that the choices we make as consumers can have far-reaching impacts.

    Are my period underwear made without added PFAS?

    If period underwear has become a part of your regular period routine, it's unfortunate to know that some of it has also been influenced by the incorporation of PFAS. And although it might help to ensure period underwear’s leak protection claims, it also raises concerns about their potential impact on our well-being.  
    In terms of PFAS and period underwear, the main things you want to keep an eye out for as a conscious consumer are brands that have been made “without added PFAS”. Being a conscious period underwear consumer means finding period underwear brands that aren’t using PFAS in their manufacturing processes and are also taking necessary precautions to limit our exposure to these toxic chemicals overall.
    Unfortunately, PFAS don’t necessarily have to be added to period underwear to still be detected in low levels. This is due to their presence in our environment or other areas of manufacturing facilities because of PFAS used in other products.  

    PFAS Free Period Underwear

    You won’t find brands saying “PFAS free period underwear”. This claim is nearly impossible given their presence in our environment. But look instead for statements about using fabrics that aren’t treated with PFAS and information regarding independent testing done by reputable organizations. Third party testing helps ensure that our period underwear has been thoroughly tested for the presence of these harmful substances and is approved safe for daily wear.

    Regulations and Industry Responses

    In response to mounting concerns, regulatory bodies in various countries have taken steps to address PFAS use in consumer products. Some jurisdictions have banned or restricted the use of specific PFAS compounds in certain applications.  
    Additionally, some manufacturers have started to seek alternative solutions to PFAS-treated textiles, focusing on sustainable and eco-friendly fabric treatments that achieve similar functional benefits without the potential risks.
