Polyvinyl chloride (PVC) contains numerous toxic chemicals called adipates and phthalates ("plasticizers"), which are used to soften brittle PVC into a more flexible form. PVC is commonly used to package foods and liquids, ubiquitous in children's toys and teethers, plumbing and building materials, and in everything from cosmetics to shower curtains. Traces of these chemicals can leach out of PVC when it comes into contact with food. The World Health Organization's International Agency for Research on Cancer (IARC) has recognized the chemical used to make PVC, vinyl chloride, as a known human carcinogen[7]. The European Union has banned the use of DEHP (di-2-ethylhexyl phthalate), the most widely used plasticizer in PVC, and in children's toys.
