Have you been hearing the buzz about PFAS? As someone interested in period underwear, you might be wondering, "what even are these chemicals and what do they have to do with period underwear?" We’re here to clear up the confusion, so you can make an informed choice about how to care for your body.
What are these PFAS I keep hearing about?
PFAS, or polyfluoroalkyl substances are commonly referred to as “forever chemicals,” meaning they take a really long time to break down. Because these chemicals do not biodegrade, they can build up in the human body and interfere with our systems. The most commonly studied PFAS chemicals “can cause reproductive and developmental, liver and kidney, and immunological effects,” according to the EPA.
This all sounds kind of freaky, especially considering that these chemicals are found in a wide range of common household products, including non-stick cookware and even some food packaging. As new studies reveal more and more evidence of adverse health consequences, the conversation about PFAS continues to change.
Okay, so what do PFAS have to do with period underwear?
Some period underwear companies use PFAS in their underwear as a stain- and water-resistant coating. Our vaginal tissues are highly sensitive and absorbent, which is why you definitely don’t want PFAS just hanging out in your period underwear.
Is Saalt Wear safe?
Yes! Here at Saalt, we are deeply committed to your health and wellbeing.
We do not use any PFAS in our fabrics or finishes and test all materials for a wide range of known hazardous substances, including PFAS and other known harmful chemicals.
We are a team of people with periods, (who are all kinda in love with our Saalt Wear) and we would never add something to our garments that we wouldn’t want in our own underwear! We are passionate about doing the right thing for our customers and for our planet.
I’m ready to nerd out. Can you show me the science?
We thought you’d never ask! Because PFAS do not break down, they are becoming more and more prevalent in the world. This means that all types of products can be exposed to PFAS inadvertently in shipping or manufacturing (kind of like that warning you see on granola bars that says, “manufactured in a facility that also produces peanuts”).
Saalt has tested our products through licensed, third party facilities and results have varied between 0 and 10ppm (parts per million) which is well below the regulatory limit of 100ppm. Extremely low levels of PFAS, like 10ppm are indicative of accidental exposure through contact with equipment or other products containing PFAS. When PFAS are deliberately added to fabrics they will appear in much larger quantities.
I’m ready to change the world, one period at a time.
Your body— and the planet—thank you for learning about PFAS and prioritizing your health! With Saalt Wear, you’ll have no waste, no leaks, no worries. Feel free to email us at firstname.lastname@example.org if you have any questions or would like some guidance to find your perfect fit.
