Because of the unique characteristics of PFAS it has become essential in a wide range of industries and products. Key applications include nonstick cookware, water-repellent textiles and outdoor gear, firefighting foams, and grease-resistant food packaging such as microwave popcorn bags and fast-food wrappers. PFAS are also used in industrial processes, such as semiconductor manufacturing, and in medical products like surgical gowns and implantable devices. Additionally, they appear in cosmetics, dental floss, cleaning products, and automotive and aerospace components. Despite their utility, concerns over their persistence in the environment and potential health risks are driving efforts to find safer alternatives for many of these uses.
Apparel: Starting January 1, 2025, New York and California implemented bans on clothing containing PFAS. Apparel companies are working to comply, though challenges remain with existing inventory. Just an example of the status of some clothing manufactures is listed.
Cookware: With lack of federal legislation many states have started to institute bans for PFAS in cookware. California's Assembly Bill 1200 prohibits the sale of cookware containing intentionally added PFAS. The law also mandates manufacturers to disclose the presence of certain chemicals on product labels. Colorado has expanded its PFAS restrictions to include cookware, aligning with its broader efforts to limit these substances in consumer products. Connecticut has enacted legislation banning PFAS in cookware, reflecting a growing trend among states to address the presence of these chemicals in kitchen products. Vermont Governor Phil Scott signed S 25, expanding the state's PFAS restrictions to include cookware, among other consumer products. Minnesota has enacted a ban on PFAS in cookware, set to take effect in 2025. This legislation also includes dental floss and menstrual products, marking a significant step in reducing PFAS exposure from everyday items. Some brands that use PTFE but not PFOA include:
Cosmetics and Cleaning Products: States like California, Colorado, Connecticut, Maine, and Minnesota have passed laws to phase out PFAS in cosmetics and cleaning products, reflecting a broader trend toward eliminating these chemicals from personal care items.
Because of limited transparency in ingredients, it is often harder to tell what cleaning products contain PFAS.
PFAS are used to create a barrier against stains and liquids.
Firefighting Foam: PFAS in firefighting foams are a problem because they are highly persistent in the environment, contaminate soil and water, and are thought to pose significant health risks, including cancer and developmental issues, to humans and wildlife. While there is no comprehensive federal ban on PFAS-containing firefighting foams, the Federal Aviation Administration (FAA) has issued guidance on transitioning to fluorine-free foams. Several U.S. states have enacted bans or restrictions on the use of PFSA containing firefighting foams. These measures primarily focus on Class B Aqueous Film-Forming Foams (AFFF), commonly used to extinguish flammable liquid fires.
Food: In February of 2024, the FDA negotiated a voluntary market phase out of PFAS grease-proofers applied to paper and paperboard food packaging (preemptive PFAS regulation). Beyond that the FDA has tested over 1,300 food samples with 97% found to be PFAS free. The current focus of the FDA is seafood which has been found to have 74% of samples to be contaminated with low levels of PFAS. In the absence of comprehensive federal regulations, several states have enacted their own laws to address PFAS in food packaging:
Beyond the U.S., the European Chemicals Agency (ECHA) has proposed a comprehensive restriction on PFAS, including their use in food contact materials, reflecting a global trend toward stricter regulation of these substances. These regulatory efforts aim to mitigate the potential health risks associated with PFAS exposure from food packaging, promoting the use of safer alternatives in the food industry.
