Your team and your guests deserve access to PFAS-free period care.

It’s common for period products to be made with cancer-causing forever chemicals.

Key Takeaways:

  • PFAS (per- and polyfluoroalkyl substances), or forever chemicals, are widely used chemicals that repel water and oil, and they are commonly found in everyday products — including some period care items.
  • Because PFAS don’t break down easily, they can remain in the environment and in the body over time.
  • Not all period products are made the same. Aunt Flow’s period products are made without forever chemicals.

What you put in your body matters, especially when it comes to period products. And believe it or not, it’s shockingly common for tampons and pads to be made from materials that are harmful to both humans and the environment alike.

Your team members, customers and visitors deserve period products that are free of forever chemicals and crafted with non-toxic ingredients — products that are made with menstruators and the planet in mind

What is PFAS?

PFAS, sometimes called “forever chemicals,” are chemicals that repel water, dirt and oil. They’re often found in non-stick pans, but they’re also found in products that contain waterproofing — including some period products.

What do forever chemicals do?

Forever chemicals don’t break down easily — instead, they build up in our bodies or stick around in the environment. According to the Centers for Disease Control and Prevention, these chemicals can represent a major cancer risk — and for menstruators, they can impact hormones, immune systems and fertility.
