Per- and Polyfluoroalkyl Substances () refers to a class of more than 4,000 chemical compounds that have been used since the 1940s for a wide range of consumer and industrial products, providing grease and water-resistance properties to them. PFAS, however, is also referred to as "forever chemicals", meaning that when they contaminate soil or groundwater, they do not easily break down or degrade into a less harmful chemical form.

Nevertheless, despite these concerns, PFAS is currently still not regulated as hazardous substances by the US federal government, so there is no national regulation to control them, and therefore the industry can only follow the individual state regulations for ensuring compliance of their products with the latest requirements. In this connection, the following table summarizes the status quo of the PFAS control in various states relating to the Children’s or Juvenile products.
