“Leach Alternative” — The Discovery Files

Researchers at University of California, Santa Cruz, have developed safer alternatives to phthalate plasticizers — which can leach out of plastics into food water and the environment — potentially preventing a variety of health problems. The alternatives can still enhance the suppleness, flexibility and longevity of plastics such as polyvinyl chloride (PVC), but they can’t leach out of them because they are chemically bonded to the polymer chain.
