When we think about fossil fuels and climate change, we don’t often think about the clothing we wear. While renewable energy sources are growing, the petrochemical industry is working to replace its loss of profits from fuel by selling oil and gas to plastics manufacturers. Because of this, toxic chemicals produced from petroleum like bisphenol A (BPA) are becoming more ubiquitous in our lives, in our environment, and even in our clothing. CEH sent legal notices to 95 companies after our testing showed that BPA levels in socks made for babies, children, and adults could expose consumers to up to 31 times the legal limit for this chemical under California law. From March to December 2021, CEH tested socks with different blends of polyester, cotton, and spandex, and found BPA in the socks made predominantly from polyester with spandex.  BPA is a well-studied hormone-disrupting chemical, known to cause developmental and reproductive harm, and can be absorbed through our skin. Exposure to BPA is linked to an increased risk for breast cancer, prostate cancer, obesity, diabetes, and other serious health concerns. These legal notices are just the beginning. Through ongoing litigation proceedings, we will push companies including Hanes, Champion, Tommy Hilfiger, New Balance, Fruit of the Loom, Reebok, and others—to reformulate their products so that toxic BPA is removed from socks. We are encouraged by the response of some companies that are working collaboratively with CEH to begin the process of removing BPA from their products. This year—and for years to come—CEH will continue to hold companies accountable when they prioritize profits over the health of people and the planet.
