California Proposition 65: 60 Day Notice of Violation for BPA in Socks
Bisphenol A (BPA) is a chemical typically found in reusable food/beverage containers, can linings, receipt tape, and various consumer products comprised of rigid plastic materials. In 2015 BPA was added to the California Proposition 65 List and deemed a carcinogen. The current dermal exposure limit is 3 micrograms per day.
On September 1, 2021 several sock manufactures and retailers received a 60 day notice for BPA in socks. Currently the socks do not contain a Proposition 65 warning label. The concern is that consumers may unknowingly have dermal exposure to BPA by wearing the socks. The use of BPA in fabrics is not discussed as often as its use in plastic and canned items. The use/purpose of BPA in fabric materials is: used in the dye agent, flame retardant production, and for antistatic reasons.
