New York recently enacted legislation that specifically prohibits the sale of products containing chemicals known as perfluoroalkyl and polyfluoroalkyl substances (PFAS). PFAS are synthetic chemicals that are resistant to water, oil and heat, and break down slowly over time. Given their durable nature, PFAS have been found to be desirable in the manufacture of clothing, particularly for their ability to repel water and stains. However, New York’s enactment of Senate Bill S1322, taking effect January 1, 2025, will create additional PFAS regulations the garment industry must now follow.
