The per-and polyfluoroalkyl substances (PFAS) are a large group of complex chemicals used to make fluoropolymer coatings and products that resist heat, oil, stains, grease, and water. These chemicals  are ingredients in various everyday products. For example, they are used to keep food from sticking to packaging or cookware, make clothes and carpets resistant to stains, and create firefighting foam that is more effective. In the textile industry these chemicals have been used to enhance performance characteristics such as water and stain resistance.

Many PFAS, including perfluorooctane sulfonic acid (PFOS) and perfluorooctanoic acid (PFOA), are a concern because they:

• do not break down in the environment,
• can move through soils and contaminate drinking water sources,
• build up (bioaccumulate) in fish and wildlife.

PFAS are found in rivers and lakes and in many types of animals on land and in the water. PFAS persist in the environment and exposure in people can occur by consuming PFAS-contaminated water or food. Exposure may happen by using products that contain PFAS.

Human health effects from exposure to low environmental levels of PFAS are uncertain. Studies of laboratory animals given large amounts of PFAS indicate that some PFAS may affect growth and development. In addition, these animal studies indicate PFAS may affect reproduction, thyroid function, the immune system, and injure the liver.

Both California and New York legislators are pushing forward proposed legislation that regulates per- PFAS content in textile products. Both states would prohibit the sale of items containing intentionally added PFAS.

The Mitchell Group has never had PFAS in any of its products.
