Bisphenol A Polycarbonite Plastic Safety
Bisphenol A (BPA) is a key building block of the polycarbonate plastic used in a variety of common products, including electronic equipment, automobiles, construction glazing, sports safety equipment and medical devices. The durability, shatter resistance and heat resistance of polycarbonate also make it an ideal choice for tableware as well as food storage containers and reusable bottles like plastic baby bottles and water bottles such as Nalgene®.
In recent years a number of researchers from government agencies, academia and industry worldwide have studied the potential for low levels of BPA to migrate from polycarbonate products and plastic water bottles into foods and beverages. These studies consistently show that the potential migration of BPA into food is extremely low, generally less than 5 parts per billion, under conditions typical for uses of polycarbonate products.
Using these results, the estimated dietary intake of BPA from polycarbonate is less than 0.0000125 milligrams per kilogram body weight per day. This level is more than 4000 times lower than the maximum acceptable or "reference" dose for BPA of 0.05 milligrams per kilogram body weight per day established by the U.S. Environmental Protection Agency.
In other words, an average adult would have to ingest more than 600 kilograms (about 1,300 pounds) of food and beverages in contact with polycarbonate every day for an entire lifetime to exceed the level of BPA that the U.S. Environmental Protection Agency has set as safe.
The European Commission's Scientific Committee on Food (SCF) has also recently confirmed the safety of polycarbonate plastic products for contact with foods and beverages. The SCF estimated total dietary intake of BPA from all food contact sources, including polycarbonate plastic products and epoxy resin coatings, to be in the range of 0.00048 to 0.0016 milligrams per kilogram body weight per day, which is below the Tolerable Daily Intake set by the SCF of 0.01 milligrams per kilogram body weight per day.
The study data and analyses show that potential human exposure to BPA from polycarbonate products in contact with foods and beverages is very low and poses no known risk to human health. The use of polycarbonate plastic for food contact applications continues to be recognized as safe by the U.S. Food and Drug Administration, the European Commission Scientific Committee on Food, the United Kingdom Food Standards Agency, the Japan Ministry for Health and Welfare and other regulatory authorities worldwide.
